NASA studies show that human productivity falls 3.6 % for every degree above 22ˇăC and 4.7% over 32ˇăC. The air quality is also affected so fresh air is required to avoid loss of staff productivity, absenteeism strains and accidents.
The heat generated by machines and processes can quickly become unbearable when outdoor temperatures increase.

JH cooler, with its simple design, offers cool, fresh, clean air at an affordable price. The outside air is filtered and cooled by the evaporation process. Investment costs are divided by 5 and running cost by 8 or even more compared to conventional air conditioning. JH cooler supplies a constant flow of naturally cooled, fresh air, without the air being recirculated.The stale air is pushed away using existing openings or with extractors.

Keeping the air quality and temperature at reasonable level means :
increased productivity
reduced operating temperatures
improved working conditions
meeting health and safety regulations
decreased absenteeism
decreased accident rate

Low investment and running costs
No compressors are used, just a fan and a water pump are necessary. Compared to conventional air conditioning JH cooler can be 5 times cheaper to install and 8 times cheaper to run !
Easy installation
No need for complicated ductwork. Choice of down or side discharge.
