Heat recovery units

HIGH EFFICIENCY WITH ENTHALPY EXCHANGER AND INTEGRATED CONTROL

from 700 to 23.500 m³/h

Supporting structure in extruded aluminium profiles and curtain panels (42mm. thick) of sandwich type with special sealing gaskets; exterior finish RAL 9002; thermal acoustic mineral wool insulation class 0 and high density.
Filtering sections of F7 efficiency class with soft bags on the outside air circuit and M5 on exhaust air circuit, removable from the side.
Fan sections with single inlet backward-curved blades plug-fans directly coupled to EC Brushless electronic motors.
Dynamic air-to-air type recovery system consisting of high efficiency enthalpy rotor, Eurovent certified, produced in aluminium alloy with hygroscopic treatment, complete with purge sector and drive belt engine designed for free-cooling management in on/off mode.
Complete control panel with remote-display and microprocessor for temperature control at fixed air flow, based on the operation logics designed to maximize energy savings and environmental comfort, thanks to the modulation of air flow guaranteed by the inverter technology. The unit is designed for RS485 connection to supervision systems based on Modbus RTU protocol.

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.
