Packaged indoor air-condition units, specifically developed for cooling of data rooms or switch board rooms with a raised floor. However, the units can also be delivered with plenum for air grille supply or support duct connections. The refrigerant used is CO2, Carbon Dioxide, a refrigerant with no ODP or GWP impact. The CO2 refrigerant is neither flammable or toxic and not subject to the F-Gas regulation.
A future safe refrigerant!
Units are connected to an external air cooled or water-cooled CO2 gas cooler (see separate information leaflets).
The gas coolers normally have an inlet temperature limitation of +20°C for water and +25oC for ambient air.
Due to these cooling temperature limitations the CO2 compressors can operate in either subcritical or transcritical condition.
