STULZ, the global specialist for mission-critical air conditioning, launched its CabinetAir PRT solution. The latest addition to the company’s innovative Shelter Cooling portfolio, CabinetAir PRT is designed to control the temperature in outdoor multifunction telecommunications cabinets. It combines the benefits of mechanical cooling with energy-saving direct free cooling technology.
Reliable operation guarantee
According to the announcement, CabinetAir PRT operates at a temperature range of -20°C to 60°C and can guarantee reliable operation, even during extreme temperature fluctuations. Its direct free cooling technology helps to significantly reduce energy consumption by using the outside temperature to cool the telecommunications cabinet.
Uwe Kudszus, product manager at STULZ, said,
“For over 40 years we have been synonymous with precision air conditioning and have designed systems for use in locations all over the world. CabinetAir PRT is the latest example of our ongoing commitment to producing reliable and energy-efficient solutions that can help telecommunications providers maximize levels of uptime. By integrating direct free cooling within CabinetAir PRT, energy-intensive compressor cooling is not required when the outside temperature is lower than inside a cabinet, leading to massive financial savings and enhancing the overall lifetime of system equipment.”
For locations with frequently higher outside temperatures, CabinetAir PRT uses both direct free cooling and mechanical cooling. In addition to this, a control panel is also available for displaying status and system messages, and for changing parameters.

The CabinetAir PRT range has three versions including fully integrated, semi-integrated, and side-mounted. The fully integrated option offers particularly effective protection against vandalism, while the semi-integrated and side-mounted variants allow more space for IT and network equipment, as well as being resilient to extreme weather conditions.
