SplitAir
Air conditioning units for flexible installation
The SplitAir is the space and energy-saving version for the reliable cooling of containers. The precision air conditioning unit consists of an indoor and an outdoor unit, and because the indoor unit can be mounted either on the wall or ceiling, it is ideal even when space is limited.

Optimum operational reliability 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 units support numerous communication protocols for integration in building services management systems.
- Data recording
- Remote configuration
- Firmware updates
- Alarm relaying
Backup operation for maximum reliability
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.
Direct Free Cooling
In many base stations and small data centers, comfort air conditioning units without Free Cooling mode are still used today for air conditioning, with high energy consumption as the result. Units from STULZ’s Shelter Cooling series exploit the potential of Free Cooling, dramatically lowering your energy costs.
Savings with Direct Free Cooling
Efficient air conduction and intelligent control of operating modes enable savings of up to 83 % to be achieved.
Free Cooling mode
In many base stations, comfort air conditioning units without Free Cooling mode are still used today for air conditioning, with high energy consumption as the result. STULZ SplitAir units exploit the potential of Free Cooling and slash running costs.
Mixed mode
STULZ SplitAir units feature Mixed mode. If the outside temperature exceeds a given threshold, Free Cooling alone is no longer sufficient. Then, in Mixed mode, the runtimes of the compressor are kept to a minimum by the simultaneous use of Free Cooling and compressor cooling. In this way, depending on the local temperature profile, annual energy costs can be cut by a further 10 %. Further potential savings are achieved by the split air conditioner working in partial load mode.
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.
Reliable operation in any weather conditions
Whether your business-critical system is working in temperatures of up to 55 °C, in ambient air contaminated by particles, in temperatures as low as -40 °C, or in a permanently humid environment – you can always rely on systems from STULZ.
Plug & Play
- 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
Flexibility thanks to variable air conduction
Due to the adjustable air supply via the front or underside of SplitAir indoor units, they are suitable for mounting both on the wall and ceiling.

EC compressor
Advantages of the speed-controlled EC compressor
- Maximum energy efficiency in partial load mode
- Constant supply air temperature
- Refrigerant R410A
- Integrated compressor soft start for low starting currents
- Long service life thanks to continuous operation without compressor on/off cycles
Control and monitoring
The SEC.blue consists of a controller and optional operator terminal. The controller manages all functions of the SplitAir unit. The operator terminal, consisting of a keypad and LCD, displays the most important operating states and alerts.
