EC Plug fan(s) circulate large air volumes evenly across the full heat exchanger surface for enhanced life expectancy.

Free blowing heaters are supplied with (loose) long throw discharge nozzles complete with horizontal louvres which can be rotated through 360o. Models 30-300 are supplied with a raised rear nozzle.

Ductwork can be fitted directly to the top of those heaters requiring ducted discharge.

Cabinets are constructed using sheet metal frame construction with profiles in galvansied powder painted panels to form a rigid and durable casework.

Panels for the heating section are provided with internal insulation along with inner heat shields manufactured from aluminised steel.

All electric motors comply with EC motor directive 2005/32/EC. This provides better overall electrical efficiency and a more consistent airflow across the heat exchanger.

Also improving the overall heat exchanger efficiency.

Inversion combustion chamber with four pass heat exchanger assembly provides improved thermal efficiency with extended life expectancy. The 304 stainless steel combustion chamber is combined with a high efficiency flat tube heat exchanger to achieve combustion efficiencies of up to 94% (ncv).

The complete assembly is mounted to allow for thermal expansion, thereby avoiding undue thermal stress and premature heat exchanger failure.

Gas fired units are supplied with a fitted high/low fully automatic forced draught burner complete with full safety controls to EN676. Heaters are CE certified and UKCA approved.

Oil fired units are also supplied with a fitted high/low fully automatic burner including safety controls.

Fire valve and oil filter are supplied as loose components. An additional external fire valve may be required in accordance with BS 410: Part2:1978.
