Air–air heat exchangers reduce running costs

Air–air heat exchangers reduce running costsRittal air–air heat exchangers can lead to attractive cost savings over refrigerant-based air conditioners due to their simple design, low energy consumption and low maintenance requirements. Air–air heat exchangers utilise the ambient air to cool the air within the enclosure interior using only two working parts.

The exchangers' operation is based on the counterflow principle in which heat is extracted from within the enclosure and released into the surrounding environment. Completely separate airflows are routed through the heat exchanger module by powerful fans that control the internal and external airflows. (Thermal winding protection on the fan motors is provided as an added safety feature). The exchanger matrix, which is made of aluminium, makes the unit light and offers excellent durability.

Units can be mounted internally or externally on the wall or roof of an enclosure. Spanning between 12 and 90W/K, the range follows a similar platform design including appropriation to UL, and units are available ready for connection along with wiring and cutout drawings. Sizes and cutout dimensions match the Rittal TopTherm cooling units, which gives the exchangers the added adaptability of being interchangeable with TopTherm cooling units.
