Industrial Heaters

Large industrial diesel space heaters. Wheeled models and containerised models. Up to a massive 383KW heat. These industrial heaters require an external fuel supply from a portable tank. Used for construction sites, exhibition tents etc. Popular in heater hire industry. Heat exchangers keep fumes seperate from the heated air.

Industrial Heater Guide

Kerosene Fuel

Kerosene is also known as Class C2 oil fuel, or 28 sec oil fuel. Where flue pipes are fitted to a heater, they have to be rated for 250 deg C (T250 rating).

Diesel Fuel

Diesel for heating is also known as Class D oil fuel, Gas Oil, 35 sec oil fuel, or Red Diesel. Where flue pipes are fitted to a heater, they have to be rated for 400 deg C (T400 rating).

Radiant Diesel Infrared Space Heaters

These popular garage heaters use diesel to heat up a large metal plate until it glows orange, radiating heat like the sun.

Portable Diesel Space Heaters

Small portable diesel heaters normally have fuel tanks, whilst large heaters usually have to be connected to a seperate fuel tank.

Direct or Indirect Heaters ?

Most portable diesel heaters are direct fired, i.e. the fan blows heat directly from the flame. Indirect fired heaters are more expensive as they have a heat exchanger and a flue. The heated air is fume free, whilst exhaust gases go up the flue.

Axial or Radial Fan ?

Most portable space heaters have axial fans. For large air flows, and especially along long ducts, radial fans (centrifugal fans) are recommended. For fans with large air flow, three-phase (400V) electricity is required.
