CWK cooler is designed for horizontal installation to cool or heat the air in a ventilation system. The design includes an access panel for cleaning and inspecting the coil, drip tray, and air channels. To ensure optimal cooling and heating efficiency, the heat exchanger must be cleaned regularly. Cleaning is made easier with the use of a mild detergent, while regular maintenance helps maintain healthier and cleaner ventilation air.

The CWK cooler housing is made of galvanized sheet steel, and the heat exchanger consists of copper tubes with aluminum fins. CWK duct coolers meet Class C air-tightness requirements according to the EN 15727 standard, ensuring efficient and reliable performance.
