STULZ CabinetAir PRT series telecoms cabinets

The STULZ CabinetAir PRT solution is the latest addition to the company’s Shelter Cooling portfolio. CabinetAir PRT is specifically 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 has been designed to offer reliable operation, even during extreme temperature fluctuations. As well as substantially 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.

For locations with frequently higher outside temperatures, CabinetAir PRT combines direct free cooling with mechanical cooling. Both modes are controlled by an integrated STULZ C100 microprocessor to cool down the inside at any time with maximum efficiency. The STULZ C100 also allows 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. Additionally, a control panel is available for displaying status and system messages, and for changing parameters.

The CabinetAir PRT range is available in three versions — fully integrated, semi-integrated and side mounted — to suit the requirements of different locations and provide maximum flexibility.
