STULZ CabinetAir PRT cooling control

STULZ has introduced its CabinetAir PRT solution, part of its Shelter Cooling portfolio and designed to control the temperature in outdoor multifunction telecommunications cabinets by combining the benefits of mechanical cooling with energy saving direct free cooling technology.

CabinetAir PRT operates at a temperature range of –20 to 60°C and provides service even during extreme temperature fluctuations. As well as lowering the noise level of active system equipment, its direct free cooling technology helps to significantly reduce energy consumption by using the outside temperature to cool the telecommunications cabinet. This is particularly effective in locations where the ambient air temperature is colder than that required inside a cabinet. For locations with higher outside temperatures, CabinetAir PRT combines direct free cooling with mechanical cooling. Both modes are controlled by an integrated STULZ C100 microprocessor, which also enables optional connection to a central building management system via Modbus RTU, as well as alarm management and a multi-level configuration menu with password protection.

The CabinetAir PRT range is available in three versions — fully integrated, semi-integrated and side mounted. The fully integrated option offers protection against vandalism, while the semi-integrated and side mounted variants allow more space for IT and network equipment.
