Precision Air Handling Cabinets
Precision air conditioning cabinet specially designed for the air handling requirements (filtration, temperature and humidity control) of computer rooms, telecommunications rooms and specific purpose rooms (electronics, sensitive storage, medical, controlled atmosphere rooms, etc.).
Chilled water
Cooling capacity: 5 to 27 kW
Air flow rate: 800 to 6 000 m3/h
Direct expansion
Cooling capacity: 5 to 47 kW
Air flow rate: 800 to 12 000 m3/h
Chilled water model (CW) – 7 sizes
Direct-expansion air-cooled model – 11 sizes
Upflow (‘over’) or downflow (‘under’)
Specially designed for the air-handling needs in small and medium-size corporate data centers
Dual-wall construction. The choice of technology used (self regulation depending on the room loads, EC motor: electronically commutated) can reduce the energy consumption.
This unit is quick and easy to install, and particularly simple to use.
