The RPL heat recoveries, for horizontal inside installation allow the combination of maximum comfort with a safe energy saving. It is more and more necessary in modern systems to create a forced ventilation, but also involves the expulsion of climate-controlled air, thus determining a higher energy consumption. The unit is equipped with a countercurrent heat recovery unit and allows an effective heat exchange between the expulsion air flow and fresh air that is pre-heated or pre-cooled, depending on the season, thus saving the energy that would otherwise be lost with the expelled exhaust air. They can be integrated in the direct expansion and hydronic systems both in heating and cooling mode.
The units of the RPL series, suitable for horizontal installation, are equipped with a crosscurrent heat recovery unit with aluminium plates for effective heat exchange, aeraulic by-pass with the free-cooling function, and synthetic filters in both internal air intake and external air emission. The recovery unit can be equipped with a post-heating system with water coil or electric resistor, suitable also for the antifreeze function. Double suction centrifugal fans or plug fans with phase cutting device paired with AC motor. Some sizes come with radial fans with EC motor and speed regulator.
