The chiller utilities are an essential part of the refrigeration system and as such must be given the best solution available that allows state of the art performance and flexibility.

Each controller dedicated to the utilities must ensure the correct storage temperature and monitor the operating conditions.

However, in addition to ensuring the basic necessities, the CAREL retail system pays special attention to energy savings and reliability.

There are solutions available that allow for high performance operation, with a subsequent reduction in energy consumption, and greater control with back-up procedures in case of anomalies, and thus greater security.

In the food industry, refrigeration is one of the most delicate and complex applications because food requires treatments at different temperatures depending upon the processing phase.

Refrigeration slows the growth of bacteria on foods. The technique is based on the extremely quick and intense action performed by the cold temperature that allows the organoleptic qualities of the food to be kept intact, prolonging storage time.

Both systems designed and installed on and industrial scale and those for large consumption are based on standard procedures and techniques. The chiller system is only one part of the more complex system that allows the evaporator to define the ideal heat exchange and thus maintain the food.

The use of E2V proportional electronic expansion valves in chiller utilities allows us to take full advantage of the available energy savings in chiller unit controls.

The possibility of operating at fully floating condensation and evaporation pressures is perhaps the primary distinctive element of energy savings as a result of the use of the E2V expansion valves.

This optimization is possible through continuous research and in real time by the better operating conditions that are possible for the entire system, an opportunity that is always ensured by using an integrated solution such as the CAREL retail system.
