NEVA Refrigeration Systems, for medium-size supermarkets


The NEVA family has been designed for medium-size supermarkets. It is characterized by simplicity and reliability.
It is the answer to widespread environmental concerns, as it combines low energy consumption and the use of natural refrigerant CO2.
While E5N models are designed for medium temperature applications only, E5N-B is the booster version which combines MT and LT refrigeration.
