RFM

Heat recovery unit
WITH REFRIGERANT CIRCUIT BUILT-IN ON/OFF AND PLATE RECOVERY UNIT
from 900 to 4.000 m³/h

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

DOWNLOAD THE TECHNICAL SHEET
 
  • Supporting frame made of sheet metal and doubleshell infill panels in pre-painted sheet metal completely removable with mineral wool thermal-acoustic insulation with a minimum thickness of 20 mm.
  • Static heat recovery unit of cross-flow air-air type with condensate collection tank.
  • Centrifugal electric fans with forward blades with double intake at 1 speed, possibly equipped with constant flow inverter motors.
  • Refrigerant circuit with heat pump (R410A) >consisting of condenser made of copper tubes and fins in hermetic scroll compressor, evaporating coil and aluminium coil, bi-directional thermostatic valve, liquid separator and receiver, 4-way valve for reverse cycle, safety valve, high and low pressure switches, freon filter and liquid light.
  • Internal electrical panel for the management of all powercommands; temperature and defrost probes for winter evaporator.
  • Microprocessor regulation, for automatic management of the room temperature, of hot/cold switching and defrost cycles; display for parametric setting and display of probe and set-point values with remote control up to 30 m from the unit.

 

 
High efficiency aluminium heat exchanger
 
Refrigerant circuit with R410A gas
 
The technical compartment outside the air flow allows
very easily operation
(1) External air 32°C 50% RH, return air 26°C 50% RH (2) External air -5°C 80% RH, return air 20°C 50% RH

The table shows the sound power values (SWL) in octave band and totals; the sound pressure values (SPL) at 1m, 5m and 10m in supply, in return and outside of the unit. All values refer to the operation of the ducted unit at MAXIMUM speed and nominal airflow.
