Find out more about the operation and benefits of our products for the various types of climate control – from air cooling and cooling units to liquid cooling and enclosure heating.
Air cooling
Operation:
- Heat loss to be dissipated up to 2,900 W at ∆T = 10 K
- The heat inside the enclosure is dissipated into the surroundings via a forced airflow (air exchange)
- Air routing inside the enclosure may be at both the extracting and discharging end
Benefits:
- Highly versatile as a result of different design variants – standard, EMC and EC technology
- Tool-free work (installing on enclosure, making electrical connections, quickly replacing filter mats)
- Lower energy costs for fan-and-filter units with efficient EC motors
- Integrated interface for easy monitoring and control of fan speed/operation in the case of EC fans
Operation:
- Heat loss to be dissipated up to 3,100 W at ∆T = 10 K
- The heat inside the enclosure is dissipated into the surroundings via a forced airflow (air exchange)
Benefits:
- Highly versatile as a result of different design variants – standard and EC technology
- Simple assembly and maintenance (innovative clamp fixing, plug terminal ensures easy electrical connection, filter mats can be replaced quickly)
- High protection category of IP 55 as standard
- Excellent efficiency and integrated interface for speed regulation and fan monitoring in the case of EC fans
Operation:
- Heat loss to be dissipated up to 900 W at ∆T = 10 K
- Unlike fans, the air/air heat exchanger consists of two closed circuits
- Instead of external air flowing through the enclosure, external and internal air flow through the heat exchanger fins according to the cross-flow principle
- The heat in the internal air is absorbed by the external air without any direct contact, which means a high protection category can be achieved, as the contaminated external air does not come into direct contact with the air inside the enclosure
Benefits:
- Reduced maintenance thanks to separate control of internal and external fans
- Easy cleaning thanks to a removable heat exchanger module
- Longer maintenance intervals, which reduces servicing costs
Cooling units
Operation:

- Energy efficiency thanks to Eco-mode control – the evaporator fan is deactivated in line with requirements based on the internal enclosure temperature
Operation:
- Heat loss to be dissipated up to 2,500 W at L35/L35
- Using a cooling medium (refrigerant R134a), the air in the enclosure is cooled in a separate internal and external circuit, and the heat is dissipated into the surroundings
- Because external air does not enter the enclosure, a high protection category is achieved
