Hecu CO₂ 

Description

By using DC inverter compressors, the Hecu sistema can offer real modulation of cooling capacity, so as to achieve low energy consumption above all at part loads. Such very high performance attainable with CO₂ means the system helps reduce the carbon footprint of refrigeration systems, an area of special interest for the food retail industry.

The high reliability of the solution dramatically reduces system down-time. The CAREL approval process also assures definition of the optimal electrical parameters, by testing all the critical points for each compressor so as to avoid all issues in the field. Hecu sistema also stands out for its real-time communication with the refrigerated units, allowing implementation of advanced system optimisation logic, with dynamic set points and extremely stable control in order to ensure perfect food preservation and reduce food waste.

Hecu sistema is available for medium and low temperature applications, with one evaporation line.
