Two new adiabatic 5,000 m3/hr cooling and ventilation units have been installed, ensuring that the air in the production hall around the injection molding machines is constantly refreshed with filtered outside air, creating a comfortable working climate in which any noxious vapors and odors emitted are vented out.
The adiabatic units operate on the principle of evaporative cooling. The ambient temperature is lowered by some 6 Celsius indirectly, with the help of a heat exchanger. During the winter, the heat recovery module is automatically switched on.
Each 5,000 m3/hr unit consumes approximately 4 kWh of electricity and 2 m3 of water per month. Rainwater may also be used instead of tap water.
It is a system that has proven invaluable in these times of corona, when ventilation is key, as it’s based on a continuous flow of refreshing air rather than on the recycled indoor air relied on by traditional air conditioning systems alone. And it has allowed us to address two separate issues with one solution: the system provides both fresh air for our employees, even after the coronavirus crisis has abated and an environmentally friendly air circulation solution.
