\n\t\t\t\t\t\t\t\t\tThe new RFD 500 heat recovery units have been designed and developed to satisfy both the exchange of air (with possibility of variation in flow rate) and its heat treatment (with the possibility of controlling the supply temperature in the rooms) and for dehumidifying, during the summer season, those rooms already equipped with water sensible cooling systems.

\n\nThe units in the RFD range recover the air in the areas to be treated. They recover 70% of the exhaust air temperature with integration of an existing heating and cooling system.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Outside air introduced into the building is cooler if compared to the return air, thus contributing to reduce the colling sensitive load.
During the dehumidifying process the unit produces warm water (with a temperature of 45\u00b0C) for free use (e.g. boiler DHW).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
