CFR-HEXA
HEXA fresh air handling units are distinguished by twin heat recovery system, together with a summer fresh air indirect adiabatic water cooler which helps to reduce the installed power.
Thanks to high efficiency scroll compressors (variable flow inverter driven type as an option) and EC motor fans, the purpose of heat loads & ventilation control is always to achieve as the highest system efficiency as the highest reduction of energy consumption and pollutant emissions.
These units, equipped with the needed additional treatment optional systems, may be a stand-alone plant solution or can well integrate central heating/cooling systems, both series and parallel layout.
HEXA series is composed of five sizes, double deck version only, to cover a needing of fresh air from 2800 up to 15500 m3/h.
The models of HEXA series can be fitted 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.
