Diesel Space Heater – high energy efficiency warm air mobile heaters – from 22 kW to 173 kW Output from Flexiheat UK

Diesel Space Heater – These diesel space heaters are fuelled either with diesel oil and have multiple safety features such as a automatic flame-out sensor which cuts the fuel supply if the flame is accidentally extinguished ensuring there will be no fuel leakage. This range of  Kroll Diesel Space Heaters are  solid, mobile diesel heaters that are ideal for spot-heating of structures such as marquees, temporary buildings, additional heating , construction sites etc.

These warm air oil fired heaters are indirect, which means that they have a heat exchanger, and all products of combustion are expelled via a flue pipe chimney, thus meaning no products of combustion such as CO2 are in the clean warm air produced, which means you don’t need to have well ventilated indoor areas. The flue kit features a straight exhaust pipe and a terminal.

These diesel space heaters are also suitable as temporary and emergency heating systems, as well as for specific applications in the construction industry, such as concrete drying and defrosting pipelines or machinery. Our diesel space heaters can also provide comfort heating to workers outdoors, as warm air ducts can be added to pipe the warm air to the desired location.

These are not paraffin space heaters – paraffin heaters – use paraffin oil which is also known as kerosene oil ( 28-second oil) , these heaters are a range of diesel heater that use gas oil / diesel  – known as 35 second oil for many benefits such as cost effective, highly efficient, easy heat control, low noise space heaters for vehicle workshops, garages, factories, workshop or site.

Quite simply paraffin space heaters / paraffin heaters must use kerosene / paraffin as a fuel, as they are designed and manufactured to use it. Thus the term paraffin space heaters / paraffin heaters.

Please note that we now have a mobile industrial heating and cooling unit with 42.9 kW of heating capacity and 33.5 kW of cooling capacity that is run off a 3-phase, 415 volt electrical supply. If this electricity is from a renewable energy source, then these units can provide a carbon-neutral heating and cooling solution.

Industrial diesel space heater – Portable industrial oil heaters

Our range of industrial diesel space heaters produce 100% clean and dry heat, and raise the temperature of the incoming air between 40-60 °C depending on model. This is known as a high delta T, which is required when using these industrial large portable oil heaters are being used in colder conditions. They have a high efficiency heat exchanger which is 92% efficient, which results in lower fuel consumption, and lower running costs. The radial fan, which is extremely powerful ensures a large heat throw of the warm air.

Applications for these large portable heaters include –

In the building industry – for the heating and drying of building sites and all-weather projects and alike

Flood restoration market – the drying of buildings after flooding or leak damage

Temporary and or marquee heating -these industrial diesel heaters are especially suited for heating marquees, sports facilities or showrooms

In the agriculture sector with the heating of warehouses and storage facilities, to protect products from frost damage or for the drying of agricultural products, such as storing or drying of flower bulbs without the customer creating risk of harmful ethylene emission.

In Industry, such as the warm air heating of workshops and transit buildings

And horticulture heating, such as the heating of poly-tunnels or greenhouses without the risk of harmful CO2 emission into the heated area.

Although technically our mobile multi oil heater is termed “mobile” in reality it needs to be located in one location, as the additional components such as the oil supply tank and air compressor that the unit requires are bulky and time consuming to move around, as you can see from the following picture
