Our full range of refrigerated display cases can be supplied as plug-and-play air-cooled units and/or can be connected to a waterloop system. With a waterloop system you can save up to 17% of your energy costs compared to a conventional COsystem.

Waterloop – the energy-efficient alternative to CO2

A waterloop is a fully integrated refrigeration system with plug-and-play refrigerated display cases connected in a closed water circuit. The condensation heat generated is transported out of the store via a pipe system. Heat exchangers can be used to recover the waste heat and to heat the store, for example.

With this system, the expansion options are virtually limitless: the individual display cases and counters can be quickly and easily connected and removed again without affecting the rest of the circuit and without the need for a specialist. This approach prevents product losses across multiple units and completely eliminates the need for a complex central refrigeration system, in turn creating advantages from the perspective of maintenance and service costs.

How much you could potentially save with a waterloop

Based on the average life cycle of 12 years for a food store

Amount saved in energy costs

- 96.000 €*
(EUR 8.000 p.a.)

Amount saved in
service and maintenance costs

- 53.900 €
(ca. 4.500 € p.a.)

Amount saved by
not having to inspect the pressure equipment every five years

- 6.000 €

*Assumptions: EUR 0.20 per kWh – branch with a floor space of 1,700 m2 –approx. 120 linear metres of refrigerated display cases and counters – 5 refrigeration cells – 2 preparation rooms
