Structure and Insulation: Corrosion resistant pre-painted galvanized sheet at the outer body. EPDM leak proof gaskets providing full air tightness at the connections of casing sheets. Tested and approved Class B fire-rated 10 mm thickness elastomeric rubber foam insulation with Low Thermal Conductivity and High Water Vapor Diffusion Resistance for thermal leak reduction.

Heat Exchanger: Aluminum cross-flow plate heat exchanger up to 60% efficiency.

Fan: Highly efficient AC plug fans with aerodynamic backward curved blades or AC centrifugal fan with forward curved blade in order to guarantee low sound level.

Filter: High air quality thanks to ISO Coarse ≥ %40 (G2) up to ISO ePM10 ≥ %50 (F7)filter classes. Long-life filters with 25 mm thickness.

Drain: Double inclined electrostatic powder painted condensate drain pan, that is manufactured from galvanized sheet metal.

Maintenance: Easy maintenance and access for fans, filters and heat recovery unit with the help of a compact design that enables easy disassembly and services doors.

Power Supply and Control: Plug-and-play unit due to factory fitted controller able to communicate with Building Management System (BMS) via Modbus RTU communication protocol.
