Reliable Cabinet Heaters From Leading Industrial Brands
A high quality cabinet heater is essential for maintaining safe and comfortable operating temperatures, protecting sensitive equipment and ensuring reliable performance in demanding industrial environments.
At National Heater Shops, we provide a comprehensive range of industrial and robust cabinet heaters from trusted brands and manufacturers such as Sealey, Elite, Arcotherm and Powrmatic amongst others.
What Is A Cabinet Heater?
A cabinet heater is a specialised heating device designed to regulate temperatures within large industrial areas. By maintaining a stable temperature, cabinet heaters help to prevent condensation, moisture build-up, corrosion and temperature related equipment failure - whilst keeping employees comfortable and productive.
These heaters are floor standing units that feature a large metal enclosure, featuring a stainless steel combustion chamber
Cabinet heaters are commonly found in warehouses, workshops, production lines, garages, and other large industrial environments.
Choosing The Right Cabinet Heater
The right cabinet heater is one that effectively and efficiently warms the desired area. We have units ranging from a compact 18kW, to large 400kW units. We also have a choice of fuel options available, from oil, gas, biofuel and waste oil to choose from.
Oil fired Cabinet Heaters
These units can be fuelled using diesel, red diesel or kerosene. They are available in a wide range of sizes, from the 18kW Arcotherm Vertigo, to the 300kW Powrmatic CPx300. Smaller units usually have their own internal fuel tank, whilst larger units need an external fuel tank. The wide range of sizes offers a solution for small workshops as well as large factories and warehouses.
Multi Fuel Heaters
Also known as 'waste oil heaters' or 'universal oil heaters'. These units can be fuelled using biofuels, such as rapeseed oil and certain vegetable oils, waste oil and diesel. They are easy to ignite and offer a great solution for garage workshops and other similar spaces. The Thermobile Bio Energy 1 offers a compact and slim profile, 27kW heat output and an airflow of 1000m³/hr.
Gas Cabinet Heaters
Also known as fixed gas heaters, these fired cabinet heaters offer a more industrial solution, for demanding applications. Top brands including Reznor and Powrmatic produce these heaters, for installation in large industrial buildings. Both LPG (Propane) and natural gas fired units are available.
When purchasing a heater, there are many factors to consider:
