Green solution to high factory temperatures
By specifying six Breezair TBA coolers, CoSaf Environments has reduced temperatures in the company's Gearbox Plant by over 10degC.
The tests were performed by the Labor Dr Rabe HygieneConsult laboratories in Germany, which carries quality management accreditation according to DIN EN ISO/IEC 17025.
Seeley International (Europe) was awarded the compliance Certificate after 16 months of rigorous live testing, carried out on its Breezair Evaporative Air Cooling system at the international furniture manufacturer Mathias Wiemann near Osnabruck, Germany where the air was already laden with bacteria, spores and endotoxins.
Testing of the Breezair installation was undertaken using the VDI 6022 standard regulations, norms and guidelines encompassing hygiene; planning; manufacture and execution; operation and maintenance and industry-specific requirements.

The successful installation of five Breezair coolers into Fortis Bank's headquarters in Brussels, Belgium has resulted in far more comfortable working conditions for employees.
Of particular interest to existing and potential users of Breezair coolers will be the results of the general ventilation testing.
Results included the quality of the input air and any potential health hazards; as well as the quality of the air leaving the cooler.
According to the VDI standard, ventilation and air-conditioning equipment for production-related areas should improve air quality in respect of particles, odours, moisture and excess heat, in addition to protecting personnel against the effects of harmful and irritating airborne substances.
During testing it was found that Breezair air coolers, which were set up with a daily pad drying cycle of 60 minutes, removed 53% of bacteria from the air, thereby providing very effective air scrubbing and removal of most of the impurities from the air delivered into the factory.
The VDI Standard also demands that for all air conditioning environments, ventilation and air conditioning equipment must be designed, operated and maintained in such a way that increased risk, due to harmful chemicals and inorganic and organic pollution is prevented.
Testing found that Breezair measurably reduced fungal spores and endotoxins were reduced significantly by 25%.
The Standard also covers industry-specific requirements for the food, timber, textile, printing and automobile industries, which require high levels of humidity to prevent moisture evaporation from products.
Breezair was found to be ideal for these industries as evaporative air-cooling adds water vapour to the air, increasing the humidity and reducing the vapour pressure deficit (VPD), which is the force that removes water from the environment.
Perhaps one of the most important findings from the 16-month of testing was the fact that the laboratory was unable to find any trace of Legionella bacteria in the Breezair coolers.
It is well known that air conditioning cooling towers are renowned as a potential source for Legionnaires disease and the Legionella bacteria thrive in any warm, non-sterile water.
It has now been scientifically proven that Breezair evaporative air coolers are not a potential source of Legionnaires disease when correctly installed with the pad drying cycle enabled.
The following statements are contained in the Report's conclusion: "No mycelia were noted on the (Chillcel) pads, which suggests that there was no fungus growth (on the Chillcel panels)".
"No Bacteria nor Endotoxins had been released from the (Breezair) unit into the surrounding air".
"There was no growth of mould on the upper surfaces of the (Breezair) unit".
Commenting Steve Kirkwood, Sales Manager for Seeley International (Europe) said: "By achieving VDI 6022 compliance for Breezair, we have broken through many barriers that have prevented evaporative air cooling being accepted in Germany.
The path is now clear for us to become a major force in the ventilation and air-conditioning industry throughout Germany and the rest of Europe".
The only company to provide a full range of evaporative coolers for a cross section of industries and applications, Seeley International's RPX, EA, TBA, ICON and Mobile air coolers incorporate the most advanced evaporate cooling technology in the world.
The systems are economic to install, they provide scientifically proven healthier working conditions and consume far less energy than conventional air-conditioning systems.
Breezair is suitable for both commercial and industrial applications in a spectrum of industries that include agriculture, horticulture, manufacturing, catering and hotels, and public and residential buildings.
Manufactured to the highest standards, the Breezair is backed by Seeley International's 30 years of experience in climate control and the company's commitment to excellence in customer service.
