Features & Benefits

Low profile

Casings are of compact design which allows ease of fitting.

Material strength

A robust unit with a double skin galvanised sheet steel casing in powder coat finish with fire resistant mineral wool infill for excellent sound characteristics.

Warranty

Komfovent Heat Recovery Unit has a 12 month warranty.

Performance

High efficiency pressed aluminium impellers are directly driven by an AC external rotor motor, designed to provide high performance characteristics.

Filtration

Units are equipped with compact, high quality air filters and filter monitoring providing customer notification of service period of filters.

Electrical

All units are suitable for 220-240V 1 phase operation or 380-440V 3 Phase dependant on model. All the AC motor specified units operate only on 50Hz whilst all EC motor specified units can operate on 50Hz or 60Hz

Quality assurance

All units are designed and manufactured with procedures as defined in BS EN ISO 9001: 2008.

Specification

Heat Recovery Units as manufactured by Elta Fans Ltd. 46 Third Avenue, Pensnett Trading Estate, Kingswinford, West Midlands, DY6 7US, UK. Tel: +44 (0) 1384 275800 - If you need more information - Contact us.

Casing

Panels are double skinned comprising two galvanized steel sheets, infilled with fire resistant thermal and sound attenuating insulation – mineral wool (l = 0,036W/mK). Units with 45 mm thick insulation may operate in unheated premises. Doors are manufactured with 45 mm insulation and equipped with locks. External casing surfaces are powder painted: RAL 7035 as standard preventing the unit from corrosion

Motors

The range of units may have either EC or AC single rotor motors fitted as standard. The motors contain sealed for life bearings.

Heat Recovery

SREGO units incorporate a rotary heat exchanger which recovers heat up to 90%, rotary heat exchangers work on the principle of heat recovery: a rotating aluminium rotor absorbs heat of the exhaust air and warms up the air supplied to the ventilated premises. SRECU units incorporate a plate heat exchanger which recovers heat up to 65%, the heat of the exhaust air is transferred to supply air through aluminium plates of the heat exchanger. Air flows through the heat exchanger crosswise. Unit design prevents penetration of the exhaust air to the fresh air flow

Quality Management

All units in the Elta range are designed and manufactured to procedures as defined in BS EN ISO 9001:2000.
