Customized refrigeration systems

Energy efficiency, capital investment, running costs, room size, noise protection, redundancy, local climate – every project has its own specific requirements when it comes to precise air conditioning. 


Our customers can choose between different configurations and so achieve an ideal balance between capital investment, running costs and energy efficiency. STULZ is the world's only manufacturer to offer such a huge spectrum of configuration options. 

A system: Compressor cooling with compressor refrigeration system based on the direct evaporator principle (DX/direct expansion) 

The refrigerant circuit of the air conditioning module consists of an evaporator, an expansion valve, a scroll compressor and an external air cooled condenser. Conveyed by a fan, the room air flows through the evaporator, where heat is extracted from it and transferred to the refrigerant. The air conditioning unit and external condenser are connected to one another by a closed refrigerant circuit.
