SYSTEMS


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 refrgeration 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 exteranal condenser are connected to one another by a closed refrigerant circuit.

AS System:

Like the A system, the AS system uses the direct evaporator principle.  To make the system even more efficient, the AS system is equipped with an infinitely adjustable EC compressor.

Water Cooled System: Simple heat dissipation via water cooled condenser

Like the A system. Difference: In the water cooled system, the heat from the DX circuit is transferred to water by a plate type or shell n tube condenser integrated in the air conditioning circuit.  The air conditioning system circulates water in a closed circuit via dry cooler or in open circuit via cooling tower.

ACW system: CW system with redundant A system (dual fluid)

Two independent cooling system (CW and A) in one air conditioning module ensure maximum failure resistance.  If the main, liquid-cooled system (CW) fails, the aircooled A system ensures that air conditioning continues without interruption.
