UT-REC

These horizontal UT-REC heat-recovery units are compact and easy to fit which makes them ideal for false-ceilings in residential and commercial applications. UT-REC units combine maximum ambient comfort with guaranteed energy savings. Existing air-treatment and conditioning systems require forced ventilation which results in the treated air being expelled, involving high energy consumption and increased costs.

The UT-REC series is designed to solve these problems by using a static heatrecovery unit that saves over 50% of the energy which would otherwise be wasted. These units, which can easily be incorporated into conventional systems made up of fan coils, radiators and conditioning units, operate in both winter and summer mode.

The UT-REC series includes seven models which offer air flow rates ranging from 250 m3/h to 3200 m3/h. The high static pressures generated enable ducting to be installed which allows air to be extracted from or admitted into several rooms.

UT REC R

The UT-REC R series is comprised of double flow fan units with rotary hygroscopic heat recovery unit and centrifugal fans. The rotor consists of alternating flat and corrugated sheets of aluminum wrapped around each other.

This results in a honeycomb structure through whose ducts pass the two air flows in opposite directions.

The surface, which has been made porous by means of special treatments, allows the humidity to be absorbed. Half of the rotor is immersed in the discharged air flow, which (during winter operating mode) gives up its heat and humidity to the matrix; due to the effect of the rotation, through these ducts subsequently flows fresh air and their sensible heat as well as their accumulated humidity content (latent heat) is transferred to it.

The UT-REC R series rotary heat exchanger makes it possible, during winter operating mode, to recover not only the sensible heat, but also the latent heat contained in the humidity of the discharged air. This allows a maximum efficiency on the order of 90% to be achieved. In the summer operating mode a portion of the humidity from outdoors is transferred to the discharged air, thereby achieving similar efficiency values. As a result of the high yield, the fresh air in the winter operating mode can be introduced directly into the space, without any need to install post-heating sections. The intake fan directs air to the heat recovery unit: in this manner any leakage of air from the fresh air circuit is directed toward the discharge air circuit.

With the adoption of the UT-REC R series’ hygroscopic recovery, condensate does not form: a portion of the humidity contained in an air flow is absorbed by the porous surface, but it is then completely transferred to the opposite air flow. Therefore, neither collection pans nor discharge tubing are necessary.

The capability of stopping the heat exchanger’s rotation, while the fans continue to operate, allows the changing of the air to occur in any case, thus creating a virtual bypass that is useful between seasons.
