EC LB Single-room heat recovery unit Air flow up to 341 CFM
Heat recovery ef ciency up to 97 %
• The CIVIC EC LB units are designed for single-room ventilation of schools, of ces and other public and commercial premises. Offer the ideal simple and ef cient ventilation solutions for existing and renovated buildings and require no layout of air ducts. • Ef cient supply and extract ventilation for separate premises. • EC fans with low energy consumption. Low-noise operation. • Simple mounting.
• Made of high-quality polymer coated steel, internally lined with heat- and sound insulation of mineral wool or other materials. • Available modi cations with an integrated preheater and reheater for cold climate applications. • EC motors are featured with high performance and total speed controllable range. High efficiency reaching 90 % is the premium advantage of the electronically commutated motors.
• Supply air is cleaned with MERV8 and MERV14 (PM2.5 > 75 %) supply cassette air lters. For premises requiring high air quality it is recommended to install carbon MERV14 lters and HEPA Filter (PM2.5 > 95%) lters. Available as specially ordered accessories. • Cassette MERV8 lter is used for extract air ltration.
The automatic supply and extract air dampers are used to prevent uncontrollable air draughts during the unit standstill.
• 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 ows through the lter and the heat exchanger and is exhausted outside with an extract centrifugal fan.
The CIVIC EC LB unit has a counter-flow heat recovery core made of polystyrene and aluminium. • In cold season the heat energy of the extract air flow is absorbed by intake air flow, thus decreasing the heat losses caused by ventilation. Condensate generated during heat recovery is collected in a drain pan and removed to the sewage system. • In warm season the heat of the outdoor air is absorbed by extract air ow. This way the supply air temperature decreases and heat recovery reduces operation loads for the air conditioner.
