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.
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.
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.
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 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.
High Quality Components: High-performance 7-blade fan assembly and redesigned combustion chamber, Jumbo Tiger Loop, 450mm One Way Adaptor, Jumbo Ecoflam Diesel Burner, 300mm Crush Proof Fuel Hose, 6000 Series ISO Male Tip Pro and BSPP Male x BSPP Male adapter.
Tough & Robust: Built to perform in challenging areas, including construction sites, workshops, warehouses, agriculture, events and more.
Portable Design: Large wheels and a handle make the heater very portable. It is easy to transport, position and re-position when required on site. Lifting eyes on top of the unit allow it to be lifted on and off transport.
