- Supporting structure in extruded aluminium profiles, panels (th. 42 mm), sandwich type, with special sealing gaskets; external finish RAL 9002; thermoacoustic insulation in high density 0 class rockwool.
- High efficiency static heat recovery >(> 70%) of the cross- flow air-air type with aluminium plates, integrated with a total motorised by-pass system; aluminium condensate collection tank, with a 1’’ double side discharge
- Dynamic recovery section created with R410A reversiblerefrigerant circuit, consisting of: EC twin rotary brushless hermetic compressor(s) with dedicated inverter, Cu/Al finned tube evaporator/condenser, electronic expansion valve, cycle reversing valve, high pressure switch, high and low pressure transducers, liquid separators and receivers.
- Compact filters th. 98 mm on the air recovered from the environment, in efficiency class ISO ePM10 50% (according to ISO 16890: 2017), extractable from both sides and compact filters th. 98 mm on the recirculation air, in efficiency class ISO ePM1 50% (according to ISO 16890: 2017), extractable from both sides.
- Centrifugal fans with free impeller with backward curved blades directly coupled to an EC motor equipped with built-in control electronics, extractable from both sides.
- Electrical panel complete with on-board machine display and microprocessor to manage the fixed-point thermoregulation in delivery, based on operating logics designed to maximise energy savings and environmental comfort, thanks to the modulation of cooling capacity and air flow guaranteed by the inverter technology. The unit is prepared for connection via RS485 to supervision systems based on Modbus RTU/ Modbus RTU/RS 485/Modbus TCP/IP protocol; Bacnet TCP; Webserver.
Electronic expansion valve
Device for constant flow (or constant pressure) Working mode
Modulating fans and high efficiency filters
(A) Input temperature ≤ 20°C; balanced air flow rates
B) Input temperature ≥ 22°C; balanced air flow rates
(1) outdoor air at -10° C 90% RH, ambient air at 22°C 50%
(2) outdoor air at 32° C 50% RH, ambient air at 26°C 50% RH; nominal air flow rate
(3) with ventilation regulation signals and heat pump at the maximum permissible value
With reference to the nominal operating conditions, the following 
table shows the sound power values (SWL) in octave band and the related results; the sound pressure values (SPL) at 1m, 5m and 10m in supply, in return and outside of the unit are also highlighted, under ducted unit conditions.
The graphs provide an indication of the useful static pressure (P a) as the airflow [m3/h] [m3/h]supplied by the base inlet unit varies. Consult the technical bulletin to check the specific data of the unit’s aer aulic performance.
