ELBA Refrigeration Systems, for large supermarkets aiming to efficiency and reliability


The ELBA family has been designed for large supermarkets and hypermarkets aiming to maximize efficiency and reliability.
Elba is the answer to widespread environmental concerns, as it combines low energy consumption and the use of natural refrigerant CO2.
It is also a form of protecting investments against cost increase and unavailability of synthetic refrigerants.
While E4N models are designed for medium temperature applications only, E4N-B models are the booster version which combines MT and LT refrigeration.
