The CIVIC EC LB units ductless ERV & HRV air handling units designed for the single-room; schools, offices, and other public and commercial premises. They offer the ideal simple and efficient heat recovery ventilation solutions for existing and renovated buildings and require no layout of air ducts.
Made of high quality polymer coated steel, internally lined with heat- and sound insulation of mineral wool or other materials. Available modifications with an integrated preheater and reheater for cold climate applications.
High efficient electronically commutated (EC) motors with external motor and impeller with forward curved blades. Such motors are the most state-of-the-art energy saving solution.
The automatic supply and extract air dampers are used to prevent uncontrollable air droughts during the unit standstill.
Supply air is cleaned with MERV8 and MERV14 (PM2.5 > 75%) supply cassette air filters. For premises requiring high air quality it is recommended to install carbon MERV14 filters and HEPA filter (PM2.5 > 95%)(purchased separately). Cassette MERV8 filter is used for extract air filtration.
How a heat recovery ventilator works. Cold outside air flows through the filters and heat exchanger, and is moved to the room with a supply centrifugal fan. Warm polluted air from the premise flows through the filter and the heat exchanger and is exhausted outside with an extract centrifugal fan.
