APPLICATIONS

Where to use ?Whenever big quantities of hot water are needed and/or big peaks of absorptionare present.� Restaurants - Hotel - Canteens� Laundries - Residential Complex - Sport Centers� Hospitals - Agrifood industry - Gyms

How does it work?Transcritical cycle operated by CO2 is ideal for efficient use of the high tempera-ture glide of refrigerant for heating water from a low temperature.

OPTIONS

� Evaporator with anti-corrosion coating� Stratified water tank� Manometers panel� Electronic soft starter� Metallic mesh for protection of finned coil evaporator� EC ventilators

High pressure CO2 at high temperature circulates in one heat exchanger - singleor double wall- and heats up in a single passage (once-through) mains water,circulated with a variable speed pump so as to reach the set water temperaturein the most efficient way.

The high water temperature makes it possible to store it in a special vessel, soavoiding, as with normal heat pumps, to mix water at different temperatures.

By using this kind of water storage it is possible to operate the heat pump atnight time, taking advantage of lower energy costs.
