MultiChiller S/M/L

Chiller with very low refrigerant charge

normal & air conditioning
heat pump

The MultiChiller forms the basis for our system concepts. It 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 refrigeration circuit with a unique plate heat exchanger.

All refrigeration components are located in a monitored housing. The refrigeration circuit has an extremely low refrigerant charge, which ranges from 0.5 to 2.4 kg of propane/propene or butane, depending on the model. Depending on the application, the outputs range from 5 to 70 kW for cooling applications and 9 kW to 90 kW for heating applications. The MultiChiller can be used as a single unit or in a hydraulic network with several units (up to 8 MultiChillers). This allows for cooling capacities of up to 500 kW and any necessary redundancies.

Compact design, easy assembly and installation

The MultiChiller is the versatile all-rounder among refrigeration systems and heat pumps. It is suitable for a wide range of applications in normal and air conditioning cooling.
The waste heat generated during the cooling process can be fully utilised. In heat pump mode, outlet temperatures of up to 90 °C are possible, depending on the refrigerant used.
The compact design of the chiller allows it to be transported with a pallet truck, and low filling quantities enable indoor installation. Developed as a plug-and-play system, the chillers can be easily installed, connected and put into operation immediately.

Individual, modular and exchangeable

Thanks to the various sizes available, the systems can be adapted to individual requirements using just one device. For higher outputs, several chillers can be easily connected together hydraulically in a network. In addition, if servicing is required, individual components can be replaced quickly and easily thanks to the simple plug-in system.

Safe, maintenance-free and environmentally friendly plant operation

A safety concept involving gas sensors and ventilation systems, as well as the use of natural refrigerants with minimal emission potential, ensure that the system operates in a sustainable and environmentally friendly manner.
