Heat recovery units

WITH BUILT-IN HEAT PUMP SYSTEM

from 900 to 4.000 m³/h

Pre-painted frame and fully removable sandwich panels with 20 mm thickness thermal and acoustic insulation.
Static heat recovery of the air-to-air cross flows type with condensation collection pan.
G4 efficiency class synthetic cell filters.
Single speed double inlet forward curved fans, on request supplied with inverter driven fan motors with constant air flow algorithm.
Heat pump refrigerant system (R410A) composed of scroll hermetic compressor, Cu-Al evaporator and condenser coils, bi-directional thermostatic valve, liquid separator and receiver, 4-way valve for cycle inversion, overpressure safety valve, high and low pressure switches, freon filter and fluid indicator.
Internal electrical board for supplying all the electrical powers; room, outside and frost temperature sensors.
Microprocessor control for fully automatic management of room temperature, display for setting and for visualizing sensor and set-point temperature values, connected up to 20 m far from unit board.

The table lists the sound power values (SWL) in octave bands and totals; it also indicates the values of sound pressure level (SPL) at 1 m, 5 m and 10 m at supply, return and at the outside of the unit. All values refer to the operation of the ducted unit at FULL speed and at the nominal flow rate.
