RECOVERY UNIT
from 900 to 4.000 m³/h
CLINICS
The RFM heat recovery units dedicated to exchange of air
and to its heat treatment (with the possibility to control
OFFICES
the ambient input temperature) have been designed and
developed in order to reconcile the many typical needs of
SUPERMARKETS
both commercial and tertiary applications.
The RFM series is based on six sizes, for air flow rates
ranging from 900 to 4000 m3/h.

INSTALLATION INSTALLATION

ADVANTAGES

• Reduced energy consumption

• Indoor installation (in false ceiling) and
outdoor installation (with cover)
• Integration with the most popular
supervision systems
• Compactness and ease of installation
• Integration of “ALL-IN-ONE” functions (air
recirculation and heat treatment)

RFM OPERATION

The units of the RFM range recirculate the air in the rooms, the thermal loads associated with the recirculation air.
particularly where the presence of smokers is permitted, All this process is performed by integrating the unit with
recovering up to 50% of the exhaust air and neutralising other heating/cooling systems.
