Heat recovery unit
These units allow to extract a certain amount of exhaust air from the room and supply an equivalent quantity of fresh air.
A crossflow aluminium plate exchanger assures an efficient heat exchange between exhaust and fresh air: therefore the fresh air is pre-heated or precooled according to the seasons.
The supply air is filtered before entering the heat recovery exchanger that is protected with a synthetic filter also at the exhaust air side.
The supply air can optionally be re-heated with a hot water coil or with an electric coil.

The URX_CF series is the mono-bloc solution designed for the installation requirements typical for public spaces like bars,
restaurants, offices, meeting rooms.
The URX_CF units combine in one mono-bloc unit, besides the fan, filter, and heat recovery sections, a heat pump refrigerant circuit
with scroll compressors of high output and low noise.
The supply air is heated or cooled, based on the season, through the heat pump refrigerant circuit located within the unit and
charged with refrigerant R410A. All this allows to have a complete unit, with the automatic operation in each season and capable of
combining the required space ventilation requirements with efficient heat recovery.
The careful design of the machine combines very compact dimensions, which permit easy installation in false ceilings, with an
excellent accessibility for maintaining all the internal components.

TECHNOLOGY
HIGH
EFFICIENCY
The units from the URHE_CF series represent the high efficiency solution to satisfy the temperature and humidity comfort and ventilation
requirements in air conditioning systems that serve public spaces and the commercial sector, such as offices, bars, restaurants, etc.
The URHE_CF units are particularly efficient machines in that they use a high efficiency cross flow plate heat exchanger of high
capacity combined with a heat pump refrigerant circuit operating with refrigerant R410A.
The use of a high capacity cross flow heat recovery unit permits a significant reduction in the operating time of the refrigerant circuit
throughout the year, thereby reducing to the minimum the electrical energy consumption.
The small unit dimensions allow an easy installation even in false ceilings, allowing excellent accessibility for the maintenance of all
the internal components.
The numerous accessories available on request, for example the high efficiency compact filters, the hot water coil or the silencers,
complete the functions of the machine which is usually combined to an air conditioning system.
