4 Lmf Clima 6 FERRARO GROUP HRS Very high efficiency heat recovery units WITH HIGH EFFICIENCY HEAT RECOUPERATOR from 3 to 4. m³/h Air-handling unit designed and manufactured for nonresidential applications, which allows to combine the requirement for air change-over with the maximum energy saving. It is equipped with a counter-flow aluminium plates heat recovery unit, complying specifically with the requirements of the EU 3/4 norm. These units naturally integrate with traditional heating/cooling systems though, when equipped with the suitable accessories, they may also be used autonomously. The series, in both horizontal and vertical execution, is divided into six sizes with air volumes from 3 to 4 m³/h. The casing is made of mm thick double skin panels, with external sheets in RAL 9 prepainted galvanized steel and internal ones in galvanized metal sheet, internally insulated with thermo-acoustic fire-proof rockwool insulation. The heat recovery unit has extremely high efficiency (> 9%) in counter-flow aluminium plates, with integrated by-pass system for free-cooling operation. Filters are M efficiency class on room air exhaust and F7 on fresh air intake, efficiency calculated according to EN 779:. Fans are backward-curved blades type, directly coupled with EC motors. The units includes an integrated control board with electronic control of all the functions: ventilation and temperature control, monitoring of the status of the filters, week programming, defrost management and anti-freeze device, fire alarm and Modbus interface. >9 % EU 3-4 COMPLIANT PLUG&PLAY EC FANS EFFICIENCY HORIZONTAL ORIENTATION VERTICAL ORIENTATION
