Thermodynamic heat recovery units series CFR-HP
The characteristics of these units make the plant installations easier, especially when they are really difficult (and much more expensive) by using common heating/cooling systems.
Description
The CFR-HP heat recovery units by SIC Srl are distinguished by twin heat recovery system for transferring the energy otherwise lost when extracting air from the room: the first system, static type, by aluminium plated crossflow heat recovery, the second system (in sequence to the previous one) by electric driven air-to-air R410A heat pump device.
Therefore, by a single independent system and at the same time, it can match the needing of ventilation while ensuring room comfort, the outside air thermal loads and the energy saving, due to the very high unit efficiency, both on winter and summer time.
Together with their compact dimensions, the characteristics of these units make the plant installations easier, especially when they are really difficult (and much more expensive) by using common heating/cooling systems. These units can be perfectly integrated into traditional room heating/cooling systems, placed in sequence or in parallel.
CFR-HP series is composed of five sizes, horizontal version only, to cover a needing of ventilation from 600 up to 3200 m3/h. The models of the series CFR-HP can be given with a ionization system of the air called BIOXIGEN®. This system, unique in his type, makes the air and surfaces of the machine, of the ducts and of the bordering rooms healthy and good smelling.
