MultiChiller S/M/L

Chiller with very low refrigerant charge

normal & air conditioning
heat pump

The MultiChiller is the basis for our system concepts. This and the associated components are part of a MultiChiller kit. They are designed and approved for indoor installation. The MultiChiller itself consists of a closed cooling circuit with a unique plate heat exchanger. All refrigeration components are located in a monitored housing. The refrigeration cycle has an extremely low refrigerant charge, which, depending on the version, is between 0.5 and 2.4 kg propane / propene or butane.

Depending on the application, the power ranges from 5 to 75 kW. The MultiChiller can be used as a single device or when using several devices in a hydraulic network (up to 8 MultiChiller). This means that cooling capacities of up to 500 kW and possible redundancies are possible. To make assembly easy, we offer a suitable hydraulic module. With this you can connect up to 8 MultiChillers at the same time. As an example, see on page 9 “MultiHydro”. Each multi-chiller is supplied via its own separate control (MultiControl). The MultiChiller V-Series has a control integrated in the housing including frequency converter.

1) excluding safety devices and gas sensors

Compact design, easy assembly and installation

The compact design of the chiller allows the transportation with a lift truck. Low filling quantities allow the installation indoors. Since the chillers are developed as plug’n’play system, they can be easily installed, connected and immediately commissioned.

Individual, modular and exchangeable

Due to the different sizes, the systems can already be adapted to the individual solution with one device only. For higher capacities, several chillers can be interconnected hydraulically without problems. Due to the simple plug-in system, it is also possible to replace the individual components or chillers quickly and uncomplicatedly for service purposes.

Safe, maintenance-free and environmentally friendly plant operation

A TÜV (German Technical Inspection Association) certified safety concept via gas sensor and ventilation system, as well as the use of natural refrigerants with minimum potential for CO2 emissions ensure a sustainable and environmentally friendly operation of the plant.
