Full Fresh-Air Self Contained Air Handling Unit
The RRU FA Series was conceived by Roccheggiani S.p.a. to meet the growing demand for air quality and energy saving. Units are intended to suit for all systems where primary air supply has to be guaranteed (e.g. systems with hydronic terminals or chilled beams, induction systems, radiant systems, update of existing systems not originally provide with the correct amount of fresh air). Fresh air handling is initially performed by a first stage heat recovery through thermal hygroscopic wheel, with efficiencies up to 85% (rotary recovery); the second stage of heat recovery is based on a fully integrated refrigerant/heat pump system (thermodynamic recovery). The ecological refrigerant R410 is adopted. The third stage of heat recovery takes place within the summer treatment, as dehumidication is conducted by fresh air reheating through hot spilled R410A (thermodynamic recovery). Units might be equipped with a water pre-heating/cooling coil; return water from radiant systems or chilled beams might be used in that coil; alternatively RRU FA units might be integrated with geothermal or solar heat sources. RRU FA series is designed and manufactured in full compliance with norm EN 1886 as certified by MIP Politecnico di Milano. Check out the attached flyer for further information.
