PWD Air / Water heat exchanger

This roof air-water heat exchanger, PWD, with a IP 55 protection degree, is ideal for dusty environments with high temperatures. Air cleanliness and the temperature around the enclosure will not affect the heat exchanger's performance. Floor standing enclosures may be cooled independently, if needed, which reduces energy consumption. The heat exchanger is placed on top of the enclosure, which means cooling can be provided also when there is not enough space on the door or side panels.

Roof Air-Water heat exchanger with a IP 55 protection degree.


The heat exchanger provides cooling without using the air immediately around the enclosure. Cooling can be provided to enclosure's that do not have enough space on the door or side panels whether standalone or as part of an enclosure assembly.


The air cleanliness and temperature immediately around the enclosure will not affect the performance of the heat exchanger, making it a good solution for dusty environments with high temperatures. Floor standing enclosures can be cooled independently of each other, if required. This avoids cooling the entire enclosure assembly, reducing the amount of energy required, saving unnecessary costs.
