High quality as family tradition

High quality as family tradition

Bernhard Mayer-Klenk, the founder of Kemitron GmbH, was passionate about top quality. He always wanted the products he developed to put a smile on his customers’ faces and to function reliably. This he also owed to himself, as he emphasized again and again, because he had known many of his customers for decades and was personally and very often also on friendly terms with them. He wanted to see them supplied only with the best; the philanthropist saw this as his motivation.

In 1977, after Chemoform GmbH – which he had built up with his brother (see history) – and he had parted company, he founded Kemitron GmbH with the support of his wife Ingeborg. And here he lived his conviction that the best quality produces the most satisfied customers and aligned his product portfolio accordingly. He also did not move his production to cheap producing foreign countries, as many did, did not buy cheap raw materials and parts when this became fashionable and also did not have his technology cheaply pre-produced abroad. Success proved him right.

“We can only maintain this high quality standard if we control every step of the product creation process,” says Stephan Mayer-Klenk, son of the company founder and his successor in the management. “This begins with the purchase of raw materials, continues with the design, which is created in-house, and ends with the company’s own production. Anything else would also contradict our corporate philosophy for environmental and human rights reasons, because our quality expectations are high here, as well.” Like his father, his success proves him right.

In the meantime, an enthusiastic third generation is already in the starting blocks (and is already contributing regularly). They have grown up with the quality standards lived out in the family. In this respect, already now many more years of best quality from Kemitron can be expected.

Perfect after an intense workout: sauna and heat

Perfect after an intense workout: sauna and heat

Many gym-goers or athletes see a visit to the sauna after a workout as mandatory. First and foremost, the stressed muscles should relax faster, muscle regeneration should be initiated and the entire body should be allowed to recover. Because the faster muscles can recover, the faster their performance is restored.

Fitness studios almost always offer a combination of strength training and sauna, and not without reason. Is it therefore advisable to take a sauna immediately after exercise? To answer this question, we should first consider what effect the sauna has on the organism.

The total body temperature of the sauna user increases during sauna. This is called overheating (hyperthermia). This is because we override the body’s own response mechanisms to heat during sauna bathing. Because even though we sweat, there is no evaporation effect in the sauna (due to the high ambient temperature) and therefore no heat release, while heat continues to be constantly supplied to the body over the period of the stay. The temperature of the skin increases from 30-32°C to approx. 40-42°C, while the heat in the body core increases by approx. 2°C (Weineck 2010, 795). This reverses the relationship of the temperature of the body core to the skin, because otherwise the skin is always cooler than the core. Increasing the core body temperature in this way raises metabolic activity to such an extent that total energy expenditure increases by up to 40%. This effect is best observed in the skin cells, because cell renewal is running at full speed there (Fritzsche/Fritzsche 1975, 15; Weineck 2010, 795).

This is also supported by a study from the American Council on Exercise (Iwen et al. (2019) Int J Res Ex Phys. 15(1):1-12). Staying warm after exercise can enhance this effect.

The researchers tested three groups – a control group, one that spent 30 minutes in hot water, and another in which participants wore a sauna suit after exercise.

Both passive warming strategies were equally sufficient to increase core temperatures, and both remained below temperatures (39°C, 102°F) that could increase the risk of heat illness.

After three weeks, mean VO2max* and lactate threshold changes were “statistically significantly greater” in both the hot water and sauna groups compared with the control group. The researchers said these post-exercise heat interventions allow people to “extend their training without increasing volume and/or intensity, meaning they can achieve performance gains without increasing the risk of overtraining or injury.

So, is heat in a sauna session after intense physical training done in the pre-run recommended or not??

Definitely yes! Because the above explained hyperthermia in the sauna leads in the muscles, cartilage, tendons and ligaments to an increased blood flow and therefore to an accelerated regeneration. The restoration of performance is achieved more quickly and not only in professional athletes.

Thus, a sauna session after training is a useful way to support the body after endurance sports or intensive strength training for effective recovery and regeneration of the muscles.

*VO2max = The maximum oxygen uptake. This indicates the maximum number of milliliters of oxygen that the body can utilize per minute in a state of exertion. It is given in milliliters of oxygen per minute.

Sauna bathing against COVID19

Turning up the heat on COVID-19: heat as a therapeutic intervention

Marc Cohen has written a paper in which he discusses the benefits of sauna bathing in the context of fighting viruses (specifically SARS-COV-2).
He writes that a healthy human body produces fever to defend itself against viruses. When using saunas, this fever heat is mimicked. Viruses – especially enveloped viruses, such as SARS-COV-2 – are deactivated when exposed to heat of 55-65°C for 15 to 30 minutes. These are temperatures that a human body can easily withstand.
Viruses are most comfortable in cool, dry weather. They first nest in the respiratory tract, especially if the mucous membranes are dried out by low humidity.

In the human body, the first line of defense against this nesting is the respiratory tract with its usually moist mucous membranes. Inhaling hot, humid air, as is the case in a sauna, can already kill the viruses located there and supportively counteract an infection.
If viruses get past this first line of defense and infect a body, our body forms a fever as a second defensive action of the immune system. All mammals have trained this immune response over 600 million years as an effective weapon against viruses. If the whole body is exposed to high heat – which is also the case in the sauna – then we mimic a fever.

Putting these facts together, Marc Cohen:
“Heat is a cheap, convenient, and widely accessible therapeutic modality with a long history of traditional use, but it remains to be seen whether heat can be effective in treating or preventing COVID-19. The relatively low cost and widespread availability of heat treatments, along with multiple mechanisms of action that include both physical and psychological dimensions, make heat an attractive option for combating viral infections. Integrating these ancient forms of treatment with modern technology can lead to greater incorporation of natural therapies into regular healthcare, with the potential to support the well-being of both patients and healthcare professionals. This can also lead to greater convergence between the health and wellness industry and the development of systems and activities that build wellness and resilience in the broader community, thereby reducing the impact of future pandemics.”

Marc Cohen is a physician and also a member of the Global Wellness Summit,
Shareholder of Maruia Hot Springs, a boutique hot springs resort in the Southern Alps of New Zealand. He is also a member of the Global Thermal Think Tank, co-founder of the Bathe the World Foundation and founder of the Extreme Wellness Institute.

Infusion fragrances - enchanting additions

Infusion fragrances - enchanting additions

According to a survey by the Deutscher Saunabund (German Sauna Association) (1), guests appreciate infusions with fragrances: only 3 percent of sauna guests want a pure water infusion, while 81 percent appreciate the addition of a fragrance. Further 12 per cent would like no infusion at all. In addition to the adequate amount of water, the choice of the right infusion/fragrance is of great importance. You are offered an almost endless variety on the market, and it is not easy to find your way around. First of all, the dosage is important: scent should be easily perceivable, but not intrusive. Therefore, do not use products where the dosage is unclear to you, high-quality products are characterized by a precise description. If you are unsure or do not want to think about the dosage permanently, you can consider using automatic dosing pumps or systems (we will be happy to advise you on this as well). Also important in terms of cleanliness and dosability is whether the fragrances are alcohol- or emulsion-based.

Some fragrances change in the heat, so you should definitely pay attention to fragrance stability and whether they fill the room long-lasting and sustainable. As a positive side effect, fragrances not only stimulate the sense of smell, but also have a beneficial effect on the psyche and, through it, on the body. Let the variety and the effect of pure nature surprise you above all. However, pay attention to natural fragrance oils, because only these have a – often already proven – effect on body and soul. In a combination of fragrances, individual scents should not overlap each other. The sequence should be adapted to the theme and type of effect (calming, stimulating, etc.). After all, plants have been used for their effects for thousands of years. Owners of private saunas can also take advantage of these effects:

Aphrodisiac: patchouli, rose, sandalwood, ylang ylang and cinnamon

Calming: alpine and mountain herbs, anise, bamboo, fennel, lilac, green tea, hay flower, elderberries, chocolate, vanilla, forest fruits cinnamon.

Concentration-enhancing: basil, peppermint, rosemary, black pepper, lemon and cypress

Relaxing: lilac, geranium, elderberry, honey, jasmine, chamomile, lavender, lime blossom and rosewood

Stimulating: anise, ice mint, eucalyptus, spruce needle, grapefruit, ginger, rosemary, sage, thyme, juniper and citrus fruits such as orange, tangerine, lemon, lime or grapefruit

Uplifting: acacia blossom, pineapple, banana, bergamot, green apple, kiwi, coconut, lime, mango, orange, rose, sandalwood, all citrus essential oils

If you feel unwell or dizzy in the sauna during the infusion, or if you experience shortness of breath, you should definitely leave – even if some tough-minded sauna-goers consider this a faux pas. Thoughtfulness towards others at the expense of one’s own health is fundamentally wrong. When in doubt, sensitive people prefer to do without the infusion altogether. The positive health effect can be achieved even without an infusion, as long as the interplay between cold and warm is maintained correctly.

CAUTION: Many fragrances are highly flammable, so never put the fragrances directly on the stones/sauna stoves. Ideally, you should drip the fragrance (a few drops are sufficient) directly into the water of the infusion bucket without taking the fragrance bottle into the sauna.

Surface disinfection

Differentiation between hygiene, cleaning, disinfection

By hygiene we mean all measures and behaviour that prevent the transmission of pathogens.
Cleaning is the removal of visible pollution and contamination as well as invisible organic material, which prevents the reproduction of microorganisms.
Disinfection we call the killing or inactivation of pathogens of any kind, to prevent infections.

Correct surface disinfection

Since there are pathogens that survive on surfaces for months and then can still be transmitted to humans, surface disinfection as an infection prophylaxis is an important measure to prevent exactly this.

For a functioning prophylaxis the surfaces must be disinfected routinely, i.e. continuously, e.g. according to a cleaning schedule. In case of the occurrence of specific pathogens or after obvious contamination, a surface is disinfected in a targeted manner.

The following areas should be disinfected continuously:

  • Surfaces with frequent hand or skin contact (door handles, handrails, keyboards, etc.). In case of infection, it should be considered to keep doors open with a wedge if possible.
  • Surfaces in communal sanitary areas (toilets, bathtubs, showers, washbasins, etc.)
  • Work surfaces
  • Floors

In hygienically sensitive areas or where infections occur, the surfaces and floors should be smooth, wipeable, joint-tight and disinfectable. Textile floor coverings are difficult to disinfect and should therefore not be laid in places where regular disinfection is required.

In general, the following should be considered when disinfecting surfaces:

  • The surface must always be wiped with a sufficient amount of disinfectant under light pressure.
  • Always follow the instructions of the manufacturer of the surface disinfectant used!
  • Suitable safety gloves protect you from infections and are kind to the skin.

After the routine disinfection of surfaces such as floors, the surface can be used again or walked on as soon as it is visibly dry – regardless of the exposure time. The disinfecting effect is still given.

In some situations, however, the specified exposure time must be waited before the surface is used again for safety reasons, e.g:

  • When disinfecting during an outbreak, i.e. during an epedemic/pandemic (formerly: plague).
  • For the disinfection of (whirl) baths and washbasins, as the disinfection is terminated by the inflow of water
  • For the targeted disinfection of contaminated surfaces
  • When disinfecting surfaces that come into contact with food and must be rinsed with drinking water before reuse

We recommend for surfaces: Kemitron Pure Desino

Pure Desino, offers you safe protection on all surfaces. Because it is not only effective against the corona virus (COVID-19), it also protects against many other viruses, such as: Herpes-, Prox-, Hepadna-, Asfar-, Fla-, Alpha-, Toga-, further Corona- (SARS, MERS), Hepatitis D, Orthomy-, Paramyxo-, Rhabdo-, Bunya-, Filo- (among others Ebola), Retro- and Arteri.

It is also microbiologically tested and is effective against bacteria, fungi, legionella and algae. It has the biocide approval – necessary for all disinfectants.

It can be used as a disinfectant over a large area on various surfaces, such as plastic, tiles, glass, natural stone, leather, wood, stainless steel, metals, etc. and is therefore suitable for almost every business and recreational area.

We recommend thorough and regular surface disinfection as an important measure to prevent infections! Please ask us or the responsible authorities for more information.

Pure Desino has a PH value of 4.5, it does not bleach and is fragrance-free.

Desino and other disinfectants are available here:

Kemitron: The Connection between Quality and Sustainability

Kemitron: The Connection between Quality and Sustainability

Throughout the more than 40 years of its existence, Kemitron has always remained true to its corporate philosophy of only processing the best quality. During this time the competition has become tougher and more dogged, the price war has often taken on difficult proportions. In other companies, production was moved abroad and cheap goods were added to the range. Kemitron has always rejected this.

According to the motto “buy right once and save twice” we believe that good quality pays off and in long term it saves both your money and our environment.

How does this work?

The Kemitron technical products (Technico) are developed, designed and assembled from high-quality individual parts in our company. They are not purchased pre-assembled. Our employees know the blueprints, the design and every single part of the products. This also applies to those that we have meanwhile modernised or have already taken out of our range.
As we pay attention to the high quality of all individual parts, our products are therefore extremely durable, which saves the customer from throwing them away and buying new ones after a few years. On the other hand, should a functional impairment occur, our products can always be repaired, even after many years of use in continuous operation. The prerequisite is, of course, that the customer follows our recommendations for use and operation.
Since development and design, as well as manufacturing is done in-house, there are no delays in customer requests, no need to send parts back and forth, not even the little power needed to send emails, because we can always go to the engineer, the designer or to the manufacturing department and ask for information.

In this way, our customers only pay once for many years of pleasure. And mountains of rubbish with environmentally harmful individual parts are avoided.

The same applies to our fragrances (Aromee) and care cleaners/disinfectants (Pure). Created and developed in our company, they are made from high quality raw materials and are extremely economical. This saves both delivery routes to us and from there to our customers, because orders are placed less frequently. Thus, not only the customer benefits, but also our environment, because fewer deliveries plus less packaging materials on the entire level can only do good for our nature. Furthermore, Kemitron products (as far as known) are not allergenic Furthermore, Kemitron products are (as far as known) due to the high standard not allergenic. The customer therefore has to order less often and buys products for which he can rely on a consistently high quality.

So while everyone is talking about sustainability, Kemitron has been living it since its founding.

Sauna and wellness in Corona times

In advance

Please note: At the moment we want to address the health issues when using the in-house sauna in a non-public area!
Naturally, here too, the general hygiene conditions must not be disregarded!

You can make your own contribution to the hygiene of your sauna as follows:

  • Do not invite people who do not belong to your core family
  • Disinfect all surfaces after using the sauna
  • Pay attention to regular and above all thorough hand hygiene
  • Avoid touching your face
  • Sneeze and cough in the bend of your arm if necessary

Sauna & Wellness plus Corona?

No one will deny that saunas have a positive effect on physical and mental health. But how does it look like when viruses, such as the new corona virus, complicate our lives? Is it still advisable to go to the sauna? We take the answer for granted: Yes! After all, right now it is essential to support the immune system. How a sauna session positively supports your immune system is explained below:

How does an infection with the corona virus proceed?

As with influenza viruses, coronaviruses initially multiply in the throat and pharynx area. In a COVID-19 infection, it is mainly the lower respiratory tract that is infected. The pathogen first multiplies rapidly and then causes an immune reaction, in many cases attacking the lung tissue and, in the worst case, causing pneumonia.

Using the sauna and the virus

First of all, it is wrong that the coronavirus cannot survive outside temperatures above 27° C! In this case it could not survive in the human body (approx. 36°C) and therefore we would have no problem!

But it is a fact: “At a temperature of 55 to 70 °C (damp heat), viruses [in general – ed.] denature their viral shells within a few minutes and thus lose their infectiousness”.[1]

Viruses do not like the hot and humid ambient air in the sauna. Especially if the temperatures are set to 80-90°C. Breathing in this hot air can also have a supportive effect against the pathogen. Regular sauna visits strengthen the body’s own immune system, which means that the body is generally better protected against viruses and other possible diseases.

In order to counteract an infection with COVID-19, you can take a sauna, but also use salt or dry salt inhalation. In addition to the above-mentioned benefits, salt activates and promotes the self-cleaning function of the lungs and is also anti-inflammatory. In addition to removing bacteria, allergens such as pollen and dust as well as viruses in the entire respiratory tract, the lungs are also cleansed in this way, thus stimulating blood circulation.

Therefore, sauna and salt or dry salt inhalation are well suited to strengthen the immune system in the long term in order to better resist the corona virus.

Swimming pool use

The chlorination of pool water kills any viruses present in the pool. However, it does not protect against viruses that have already entered the body, because they are not affected by chlorine or other disinfectants!

General hygiene in pools and wellness areas, when lock-down ends

Saunas and wellness areas have always required very high hygiene standards. Regular inspections by external hygiene institutes check and document their compliance. This applies to all areas where guests may come into skin contact.
When the lockdown is ended and public areas can be used again, there will certainly be regulations that will guarantee the safety of every single person. We will provide more detailed information about these in due course.

Herbs can help!

Natural essential oils are used in many different ways for room scenting or also in bath salts, perfume, facial oils and creams. However, not only do they help to spread an enchanting scent, in difficult times natural essential oils can also be used for a larger purpose:

Since scents act on the body through the oldest part of the human brain, the limbic system, they subconsciously trigger an immediate reaction in us. Because emotions are handled and controlled in this part of our brain. They are not pre-processed and filtered by the thalamus like optical or acoustic stimuli. Thus they can trigger feelings in us quite unconsciously and influence our state of mind. And because our sense of smell is closely linked to our mood and feelings, essential oils are used specifically to increase our physical and emotional well-being. Now different scents are attributed with certain effects, invigorating, promoting concentration, decelerating ... Today we want to concentrate quite consciously on the scents that are supposed to have a calming, stress-relieving or relaxing effect on us. In addition, create a relaxing and calm environment and practice relaxing breathing exercises.

Depending on health, physical condition and stress situation it can be said in principle: Flowery, soft and subtle woody notes are harmonising, whereas bitter, herbaceous or strong woody notes are calming.


The bergamot is known to give Earl Grey tea its unmistakable taste as a citrus fruit.  Its fragrance is said to calm, relax and soothe restlessness, while at the same time helping to regain energy. Attention! Bergamot oil can increase your sensitivity to sunlight!


The geranium is one of our most popular balcony plants and is said to have a relaxing effect, especially in cases of stress and exhaustion.


Jasmine fragrance is said to be able to support you in your worries. The scent is believed to calm the nervous system, lift the mood and give new energy. For a positive start into the day, you can try to be inspired by the scent of essential jasmine oil already in the morning.


Chamomile is known as a soothing fragrance. It is said to have positive properties to promote inner peace and restful sleep, and to alleviate irritability, brooding and worry.


The unmistakable scent of lavender can help you relax and relieve the nervous system. It helps with difficulties in falling asleep and for a peaceful night's rest. Restlessness, irritability and insomnia are said to be relieved by lavender scent.


Melissa is considered a proven household remedy against stress, nervous tension, melancholy, depression and sleep disorders.  The scent of melissa is said to have a harmonizing effect on body and mind.


The orange scent is supposed to lift the mood and help to cope with stress.  So it is just the right thing for those who suffer from listlessness, nervousness and exhaustion.


Traditionally the rose is associated with love and the heart. It is said to calm sadness or inner turmoil. It is also said to help relieve tension and worry.


The scent of rosemary is said to awaken the spirit of life and support migraine, stress and exhaustion. Furthermore, it is believed to have warming and circulation-promoting properties.


The fine aroma of vanilla is supposed to lift the mood, exude a warm atmosphere and also serve for relaxation.


Incense can look back on an already very long history.  It is extracted from the resin of the incense tree and can be used to relieve tension and relax the mind. Traditionally incense is used to deepen meditation.


Ylang-Ylang oil comes from the flowers of a tropical tree.  The fragrance is said to reduce symptoms of anxiety and depression, lift the spirits and relieve headaches. Attention! It can possibly lower blood pressure, so it should not be used by people with low blood pressure!


The aromatic scent of lemongrass is not only said to have a stimulating and very refreshing effect, it is also said to relieve anxiety, lighten the mood and help with listlessness.

Please always keep in mind: Fragrances can have a supporting and relieving effect in many ways. However, please always follow the dosage instructions and the recommendations on the label or package insert. For medical purposes, seek advice from trained specialists! Aromatherapists and doctors will be able to help you at any time.
