Industrial portable indirect heaters – M series- oil or gas fired mobile heaters
Industrial portable heaters – gas and diesel heaters – Output range from 22kW to 173kW of heating power fired by Diesel Oil, LPG Gas or Natural Gas
Efficient, reliable and applicable anywhere essential for heat distribution via warm air hoses, makes these a great heater for large space industrial use heating with the fuel type options of red diesel or gas in these highly energy efficient industrial fan heaters.
Due to the high-power radial fans fitted to this range of mobile heaters, these units are especially suitable for heat distribution with warm air hoses. This ensures efficient heating from outside the building for many applications such as a warehouse ,marquees, exhibition halls, medium sized commercial or industrial premises that is being heated.
They are also used on building sites to provide temporary heating, comfort heating or to provide heat for frost protection. With their high delta T – they are particularly suited to reduce drying times in construction.
The optional re-circulating air module allows an even more efficient and economical operation, and come as standard with a remote thermostat socket so these gas and diesel heaters can have adjustable thermostatic control to deliver warm air at your required desired temperature.
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. More on this dedicated webpage – Industrial portable air conditioner
Industrial space heaters diesel
When fitted with a diesel burner, the M series of portable industrial heaters, can be called a mobile or portable diesel industrial space heater. When supplied in this configuration, these mobile warm air heaters have an integral fuel tank and heating cartridge ( which ensures reliable starting of the heater) on the M25 and M50 models ( also an option on the M70 industrial portable heater model )when supplied with the red diesel oil burner version, make these portable industrial space heaters independent, space saving and immediately ready for use.
The diesel heaters models M70 to M200 have a oil fuel supply pipe to be connected to an external oil tank and a preheated filter which makes them also immediately ready for use. Quality branded oil burners and silent, yet powerful fans convert more than 93 % of the energy into heat.
Industrial Portable Propane Heater
Another option on these industrial mobile heaters is to have an LPG or Propane burner fitted to these mobile industrial heaters. This allows you to your propane as your preferred fuel source to provide warm air heating. You can then use propane cylinders or even use a bulk propane tank.
Some customers prefer this fuel as an option as it does offer some benefits over oil for example, as there is no risk of oil being spilt and contaminating the ground, although there are some downsides to propane, as any cylinders need top be protected from tampering with by any unauthorised people – This is normally achieved by placing the propane cylinders in a protective cage.
Whether an industrial portable propane heater is suitable for your mobile warm air heating application is down to you and your site conditions and applications

How far with these heater blow the warm air ?
Mobile Heaters – Pascal ( Pa ) explained -Air Pressure is expressed Pascal and has been since 1971.The SI unit for pressure is the Pascal (Pa), equal to one Newton per square
meter (N/m2 or kg·m−1·s−2). This special name for the unit was added in 1971; before that, pressure in SI was expressed simply as N/m2
Mobile Heaters have the units generated air pressure normally expressed in Pa
For example a M70 Industrial portable heater will produce 180 Pa
Everything that is attached to the end of a heater causes frictional resistance, and this depletes the amount of PA available after going through the duct or a bend in the duct etc
We have some approximate values for calculating how far our M series portable industrial heaters can blow the warm air –
For every 1 metre of duct, (it doesn’t matter if it’s horizontal or vertical) = 2 Pa /metre
A 90 degree bend in the duct = ca 20 Pa , Single warm air hose connector = ca 15 Pa
Minimum desired pressure at the end of a duct = ca 30 Pa
Thus a M70 heater with a straight run of ( warm air) duct could do –
Heater pressure – 180 Pa
Less desired PA at the end of the duct – 30 pa , less warm air hose connector – 15 Pa
= 135 Pa
= 135 Pa dived by 2 Pa per meter = 67.5 metres of straight duct
