E.COOLINE COOLING CLOTHES for better performance

Health and safety at the workplace in hot ambient temperatures is difficult to achieve. Often clothing is soaked by sweat and the staff is exhausted, has problems to concentrate which results in mistakes and accidents and working performance is at its lowest. Some even have severe health problems. Especially workplace safety decreases drastically. Personal protection equipment (PPE) provides heat protection from external factors as radiation heat but often even worsens the heat stress for the person inside the suits.

Not only people are affected by heat problems companies also lose performance.

Different studies worldwide determined that productivity decreased by 12% on hot days. With the help of an online survey carried out with 88 companies in Germany, a bachelor’s thesis analysed heat at the workplace and its effects on workers and companies.

Too many employees
affected by heat

  • 0-10% of our employees are affected 49% 49%
  • 10-20% of our employees are affected 23% 23%
  • Over 30% of our employees are affected 16% 16%
  • 20-30% of our employees are affected 11% 11%

More and more companies report that heat is a problem for a significant part of their employees. 34 % of the companies say, that 10-30 % of their employees are affected by heat and even 16% of the companies talk about over 30% of their workforce with heat. Especially elder employees suffer from high temperatures and the average age of the workforce in companies increases. It is evident that the impact of heat to the attractiveness of companies can be significant.

About 25% of the companies, do have workplaces over 37°C all over the year. 53% of the companies operate with workplaces with such temperatures at least in summertimes.

Illness rate is higher in heat



  • Yes, Accident- and illness rate is higher in heat 75% 75%
  • Only 4% of companies think that there is no impact 25% 25%

Too much companies report that the stress level of their staff increases in heat.

75% of the companies interviewed believed, that the sick rate was elevated when temperatures rise. Apart from health problems of workers, this evidently led to higher downtimes. This resulted in less overall productivity.

Lower performance
by high temperatures?

  • Yes, concentration and performance of employees is lower in heat 96% 96%
  • Only 4% of companies think that there is no impact 4% 4%

96% of the interviewees said that concentration and performance was decreased at hot temperatures, which had a direct effect on performance. 

Another aspect regarding heat is aggressiveness. This aspect is additionally supported by studies of Solomon Hsiang of Berkely University. In 2009, Wuppertal University found out that aggressiveness increased in heat. This issue is supposed to be reflected in the working atmosphere and shop morale.

The question whether the working atmosphere deteriorates in heat or whether conflicts or aggressivity increases in heat was analysed. Although this aspect is relatively new, more than 50% (56%) of the companies being interviewed confirmed the question.

Workplace analyses confirm cooling efficiency

Workplaces with temperatures exceeding 26°C or even 37°C are found in many facilities, mainly in steel mills or chemical factories but also at construction sites and in the automotive industry. E.COOLINE was already successfully tested in most of these working areas. In all situations, E.COOLINE helped to keep the body temperatures of the employees at normal physiological level, i.e. between 28-32°C.

Thermo kinetics study with E.COOLINE

The “THERMOMAN*”study conducted by the Swiss Research Institute Empa – Materials Science and Technology in St. Gallen confirmed the efficiency of E.COOLINE. The parts of the body protected by the high-tech material showed a lower temperature rise than those not protected by the new high-tech fleece. Cf. Empa study report n° 204’959


Cool instead of flabby

Better cooling effect at high temperatures

A thermo kinetics laboratory study carried out in-vitro of the high-tech material determined a temperature reduction by 6°C from 24°C to 18°C. With outside temperatures of 30°C, the temperature on the high-tech material was determined at cool 16°C for more than 20 hours.

The quantity of water evaporated in the 3D structure of the E.COOLINE material is, per time unit, higher at elevated temperatures and thus produces a greater cooling effect through higher energy consumption. Cooling at lower temperatures is also lower because less water is evaporated per time unit. E.COOLINE reacts similar to an automatic air conditioning system. At high temperatures more cooling energy is released.
