Optimum operational liability for your application
Connectivity for maximum availability
Monitoring and remote diagnosis are available for all units via a web interface. This enables rapid intervention and therefore immediate troubleshooting in all situations. What’s more, our outdoor air conditioner units support numerous communication protocols for integration in building services management systems.
Backup operation
Backup operation for maximum liability
In telecommunications, in particular, high reliability is vital to prevent any loss of network availability. Thanks to the additional 48 V DC power source, backup operation with Free Cooling is available. If the main power supply fails, the Shelter Cooling units continue providing backup cooling to keep your system running reliably.
Available operating voltages:
- 230 V AC 1ph 50/60 Hz
- 230 V + 48 V DC backup cooling
- 48 V DC
Direct Free Cooling
When it comes to reducing energy consumption and costs, Free Cooling offers the largest potential for energy savings. CabinetAir PRT uses filtered outside air to provide optimum air conditioning for the outdoor cabinet. The air conditioning system is operated in Direct Free Cooling mode for most of the year - this creates enormous savings potential. If the outside temperatures rise above the supply air temperature setpoint, an integrated DX system with a compressor automatically provides air conditioning.
Savings with Direct Free Cooling
Efficient air conduction and intelligent control of operating modes enable savings of up to 90 % to be achieved.

Free Cooling
At low outside temperatures, outside air is used directly for cooling. The outside air is conveyed into the interior when the air damper is open. Energy-intensive compressor cooling is not needed when outside temperatures are low. This way, Free Cooling brings you huge potential savings.
Compressor mode (DX)
If outside temperatures are so high that the outside air would no longer help to cool the inside, all cooling is generated using the compressor. Even in this mode, the perfectly harmonized components we use keep STULZ air conditioning units working reliably and efficiently.
Low-noise operation
Optimum air conditioning keeps the entire system running quietly
Especially in the vicinity of residential areas and offices, noise emissions should always be kept to a minimum. CabinetAir PRT is designed to ensure that the air conditioning keeps all system equipment running quietly. Regardless of the outside temperature, the air conditioning system creates ideal operating conditions, drastically reducing the noise level of the system equipment as a whole.
Plug & Play
- Simple installation and removal
- Fast and easy replacement of units while the outdoor cabinet is still in operation
- Units can be serviced and replaced by the operator’s own personnel (no refrigeration engineers required)
- All products in the Shelter Cooling series are factory tested, filled with refrigerant and ready for connection and operation right from the start
- Reduced installation time and costs
- Speedier start-up
Individual installation options
The units are available in three versions for maximum flexibility. Whether you need more space for your IT equipment or protection from vandalism and adverse weather – the CabinetAir PRT will satisfy all your installation requirements.
Reliable operation in any weather conditions
Whether your business-critical system is working in temperatures of up to 60 °C, in ambient air contaminated by particles or in temperatures as low as -20 °C – you can always rely on systems from STULZ.
Control and monitoring
The C100 control system is a microprocessor-controlled I/O controller installed in the control box of the air conditioning unit. An optional operator terminal is required for displaying the operating status and messages, and for changing parameters.
Options
Thanks to the numerous options available, you can perfectly adapt STULZ units to your particular requirements.
- Electric heater
- External operator terminal
- Connection to common BMS systems via Modbus RTU interface
- Available operating voltages:
- 230 V AC 1ph 50/60 Hz
