Airrex 2500 21000 btu capacity industrial spot cooler

A powerful unit suitable for office, industrial and commercial environments. A versatile high capacity unit with a vent hose of up to 9 meters all off a standard 240v 13amp supply.

This unit has options for ducting;.

The insulated 2.8m reducer duct fits on the exhaust spigot to allow the exhaust air to be directed either to ceiling void or through a window. The diameter of the duct is 17" at the inlet end and 12" at the outlet end making it easier to handle. The insulation ensures that the extracted heat is not dissipated back into the room via the duct walls.

The 3m insulated duct extension can be connected to the outlet of the insulated reducer to provide extra reach to get to the point where the warm air is discharged.

The 3m un-insulated duct extension is again an option to connect onto the reducer section, however it is in tended for applications where there is no problem with the exhaust duct dissipating heat through the duct walls.

The 3m cold air extension ducts fit onto the units own cold air delivery ducts to provide extra reach for the delivery of cold air.

Please not that this machine is designed to work effectively with up to 9m of ducting. That is either 9m on the warm air exhaust side, or 9m in the cold air delivery side, or some combination of the two where the overall length is no more than 9m.'TitleValue Cooling capacity21000 BTU Condensate tank volume12 litres Power consumption2.41 kw Operating Temperature18-45.
