100% Clean Hot Air: The heater blows out 100% clean, fume-free warm air from its warm air outlet. This makes it ideal for heating enclosed areas safely, such as marquees and tents, workshops, warehouses, areas on construction sites and much more.

Ducting Connection: Sections of ducting can be attached to this heater, in order to direct the clean warm air into the space that you need to heat.

Flue Gas Exhaust: Combustion by-products are exhausted out of the top of the heater. Sections of flue pipe are available separately, allowing you to safely vent exhaust fumes away from the space.

Fan Options Available: The axial version, the IMA 111AX, generates up to 130Pa of pressure build up, whereas the radial fan version, IMA 111RAD, offers up to 300Pa of pressure. The high pressure radial fan version, IM 111RHP, offers up to 500 Pa - ideal for distributing air through long lengths of ducting.

Tough & Robust: Built to perform in challenging areas, including construction sites, workshops, warehouses, agriculture, events and more.

Portable Design: Forklift slots, large wheels and a handle make the heater very portable. It is easy to transport, position and re-position when required on site.

Thermostat Connectivity: An optional heavy duty thermostat can be connected to this heater, allowing you to set a required temperature within the space. The thermostat will switch the heater on and off as required in order to maintain the set temperature. This saves fuel and adds extra convenience.

Tigerloop Included: This heater features no internal fuel tank. It is designed to be connected to an external fuel tank of your choice. The tigerloop removes any air from the fuel as it enters the heater.

Fan Only Switch: Allows the fan to operate without heat in order to ventilate areas when required.
