Heat recovery unit
VMC-EFresh air terminal unit with counterflow static heat recovery.
Key features
Extremely compact
High efficiency recovery
Very silent
Brushless DC fans
Description
Construction features
• Galvanised sheet steel self-bearing structure, insulated internally and externally.
• Recovery unit: thanks to a high yield static type heat exchanger with back-current flows consisting of flat layers of special paper that allow total heat exchange, thereby recovering both sensitive and latent heat. The air flows are kept separate with relevant sealing.
Maintenance is easily performed on the heat exchanger and filters thanks to side extraction.
• By-pass motorised system of the recovery unit actuated automatically by the electronic control
• Air filtration in F9 efficiency class (with G3 pre-filter) on the fresh air and G3 filter on return air.
• Integrated dirty filter signal pressure switches
• Fans: fresh air inlet and centrifugal exhaust with BRUSHLESS EC motors that allow higher efficiency to be achieved in comparison to traditional motors with energy savings of up to 60%. 10-speed management option.
• Ducting connections with plastic round fittings.
• Incorporated electrical panel with electronic board to control the freecooling and fan functions.
Separately supplied accessories
• KSBE1: electric pre-heating heater with defrost function complete with safety thermostats and control relay, which can be activated from the KPCM panel
• KSBE2: electric post-heating heater complete with safety thermostats and control relay, which can be activated from the KPCM panel
The two units cannot be managed at the same time, so they are one as an alternative to the other
Controls
• KPST- Touch screen remote control panel
• KQSW- CO2 wall sensor for fan adjustment
• KUSW- Wall humidity sensor for fan adjustment
