Product Description

Designed and developed with outstanding, unique features.  The heavy-duty, IP55 rated air circulation fan is mounted on the under-side, taking in the coldest air whilst preventing the fan blades from collecting dust, as happens with side and top mounted fans.  Fan is selectable, allowing for either continuous operation or to run only when the heater is firing.

The externally mounted burner is supplied to burn either oil (kerosene or paraffin) or gas (natural or LPG), and are interchangeable, allowing you to switch to the lowest cost fuel (providing you have both an oil and a gas burner).  The burner has a self-diagnostic control for ease of service/set-up, and the complete burner can be easily removed and sent away for servicing without the need for an engineer to visit your site.  This ‘quick-release’ feature means any new type of burner can be easily fitted at a later stage making this heater future proof.

The control panel is mounted in an IP65 rated enclosure, and comes with a digital temperature control with remote sensor.  Alternatively, control relays can be fitted for computer control.

Requires single phase 230v AC power supply (3-phase can be supplied)

Available in three sizes – 75Kw, 100Kw or 120Kw

Full nationwide installation service offered. 

Direct Fired Models

The main body is galvanised, for long life, and has removable covers allowing quick and easy internal access. The extra-long, stainless steel combustion chamber keeps the body of the flame within the surrounds of the heater.  It also features an after-burn cassette to ensure cleaner combustion, a worthwhile advantage considering the bi-products of the combustion process remain within the building.

For the natural gas models we specify 1/2” gas hose for the 75Kw and 100Kw heaters, and 3/4” for the 120Kw unit.  For propane (LPG) heaters we recommend using a 2 bar, two bottle changeover valve with a 37mb pressure regulator fitted at the heater.  This will ensure the heater receives the fuel at precisely the correct pressure.
100% efficiency with clean combustion
Direct-fired heaters enrich CO2 levels

Extras: Air duct kit, which brings clean air from outside of the building straight to the burner for even cleaner combustion, sling kit for suspending the heater, floor stand on which to sit the heater, auto changeover valves, regulators, hose etc. See page 80.
