Thermobile AT307 Waste Oil Cabinet Heater

Save time, money, effort and waste by recycling used oil

Using a revolutionary system that can utilize recycled waste oil as fuel, the Thermobile AT307 universal oil fired heater has the potential to save the operator thousands of pounds in fuel bills over its total service life, whilst at the same time offering exceptional and consistent performance. These cabinet heaters can be fuelled with diesel, red diesel, bio diesel, 35 second heating oil, processed fuel oil (PFO), rapeseed oil, linseed oil, certain vegetable oils and waste oil from diesel or petrol engines, gearboxes, transmissions, hydraulic systems, diesel oil or any combination of these. (Subject to licensing control). The following must not be used; solvents, thinners, petro-chemical based oils, transformer oil or any oil above S.A.E. 90.

100% clean, odourless heated air

Perfect for both commercial and industrial applications

This waste oil heater utilizes a built-in fuel tank, perforated combustion chamber, and internal vaporizing burner to maximise the efficiency from whatever fuel source has been implemented and offers a fixed outlet temperature of between 50 and 70 °C. Despite having the ability use waste oil, this doesn’t mean that the air or heating quality is compromised, as like other Thermobile heaters of this type, the AT 307 only emits 100% clean, odourless air. This unit also includes an extra burner dish as standard. The fumes produced during the combustion process are flued out of the space using a flue kit (sold seperately).

The Thermobile AT307 produces a combination of radiant heat plus hot air from the top mounted 'THERMO’ blower, to heat spaces safely and effectively.

Perfect for applications including workshops, warehouses, transit sheds, garages or other locations that may benefit from utilizing waste oil, this cabinet heater also possesses all the characteristics that make it suitable for day-to-day use. The safe outer shell casing is durable and powder coated to effectively protect the internal components from accidental damage on site.

Safe, reliable and exceptional build quality

Starring oil overflow and overheat security thermostat

During operation, the Thermobile AT307 heater also employs an overheat security thermostat and oil overflow security protection which also goes towards this protection and promotes positive maintenance practices.

Please observe all manufacturer recommended conditions and safety information when operating these heaters, and ensure correct and suitable ventilation is properly implemented before use. Please also ensure all local and national building rules and regulations are followed before operating.
