CoolRAC DF
New design
Combines the advantages of CW and XC systems — free-cooling for low and medium outdoor temperatures and direct expansion cooling for use during high outdoor temperatures. The system thus reaches optimal minimum operating costs without the need to compromise.
Product introduction
A range of indoor Room-Cooling Units. Variable fan module installation allows for air outlets above the floor, in a raised floor, or on ductwork. CoolRAC units can be equipped with numerous additional accessories and fitted with one or two powerful radial EC fans for increased redundancy.Key benefits of the product
- Cooling capacity up to 46 kW
- Free-cooling for the majority of the year — the unit has the most efficient heat exchanger in its category
- Smart control system uses free-cooling to pre-cool the air even during high outdoor temperatures — energy consumption thus remains minimal
- Investment in the unit returns within a few years thanks to savings on operating costs (compared to DX or XC systems)
- Since the main heat carrier is water, waste heat can be reused for heating or other purposes to further reduce costs
- The water circuit and compressor circuit can be connected to two separate water sources — the unit can thus be fully redundant
