Waste Oil Burner / Universal Oil Burner -KG/UB Models
Waste Oil Burner – Output range 26kW to 190kW
Waste Oil Burner -Warm air heaters are the most economical way of heating a commercial or industrial workshop,factory, garage, warehouse etc. especially when they are run with a multi/waste oil burner instead of a conventional oil or gas burner. Flexiheat offers you a large product range of warm air waste oil heaters and boilers, specially designed for this purpose.
Without any significant modifications, mineral oils, vegetable oils and animal oils can be used as a fuel source. There are no special tools required. Just turn a dial to adjust the pre-heating temperature and the combustion air to the oil in question.This is one of the very few burners to be designed and approved to burn pure rapeseed oil and conforms to European Standard EN 267 with relation to rapeseed oil according to DIN 51605. This makes it a full bio oil burner, from B10 to B100 classification for bio oil.
Waste Oil Burners – How do they work ?
The combustible oil is atomized using compressed air at comparatively low pressures.This allows us to use larger nozzle diameters which prevent blocking of the nozzles,even if polluted or viscous oils are being burnt. A separate fuel supply system lifts the oil out of the storage tank and pumps it reliably over large distances to the burner. Here, it is filtered and preheated.This is important – for a consistently good quality of ignition and combustion of the waste oil.
Economic and Environmental Benefits of Multi Oil Burners
Due to the ever increasing cost of mineral oils, vegetable oils are playing an more important role as a fuel source. Their calorific value is very close to the values of heating oil. Vegetable oils are renewable , CO2 neutral and do not contain any sulphur or heavy metals.
Waste Oil Boiler or Waste Oil Warm Air Heater
Most new and old boilers, and our Waste Oil Warm Air Heaters can easily be equipped with a Kroll universal / waste oil burner, giving you the flexibility to choose the oil you want: be it for economic or ecological reasons , or a combination of both.
This range of burners require a compressed air supply , many sites have their own supply or we do a very quiet compressor, which has been specifically designed to create the compressed air required to run our burners. Our compressors are the diaphragm type ( Oil Free )and are continuously rated, which is very important as many compressors aren’t, requiring very little maintenance and are also very quiet – 70dBA max , for reference normal speech is 60dBA. This is an important factor , as for example when used with one of our waste oil boiler set ups, if the boiler thermostat says you need heat at 3 AM in the morning, the last thing you need is to be woken by a big noisy compressor ! Also as our compressor is controlled via the burner, and only operates on demand , there are large energy savings achieved by using one, meaning lower running costs. They are also very compact , roughly of the size of a small briefcase
Fuels that can be used in the Kroll universal / waste oil burner –
- 35 second Heating Oil/Diesel
- Processed Fuel Oil ( PFO )
- Rapeseed Oil
- Linseed Oil
- Most Vegetable Oils
- Used Engine Oil
- Bio Diesel
- Hydraulic Oils
We believe we have the best waste oil burner for sale worldwide, let alone the best waste oil burner in the UK & Ireland

Compressed Air supply for Waste Oil Burners – FHMOB Range
We encourage you the customer to use compressors with tank capacities of 80-100 litres, thanks to which the compressor operation pause times can be extended, as meany compressors aren’t continuously rated . In case of the waste oil burners being installed in areas where the noise levels can’t be high, we suggest using screw compressors or medical compressors, the noise levels of which amount to 45-50 dbA.
Waste Oil Burner – Maintenance of the FHMOB Multi Oil Burners
These Flexiheat waste oil burners are designed for continuous operation throughout the entire year, and do not require daily maintenance. However, due to normal wear of the burner components, it is recommended to have service personnel maintain the appliances at least once per year before the start of the heating period. In case of burners operating all year long without a seasonal brake, then service the burner after 2,500 hours of operation. The fuel system requires maintenance in terms of cleaning of filters found in the fuel tank and the precision cleaning filter placed just upstream from the pump. The filter cleaning frequency depends on the type of fuel used for combustion. For light fuel oil (i. e. kerosene / gas oil and similar), this time may be extended to a couple of heating seasons. Flexiheat UK, despite this, recommends cleaning of filters before each heating period. In case of use of waste fuel, mineral oils or plant oils, filter cleaning is recommended every 700 hours of operation. Note burning used vegetable oils, please ensure they do not contain excess solids, as these shall cause the filter cleaning periods to shorten drastically. It is recommended to place a vacuum meter on the fuel filter clean side to control the filter cleanliness on a continuous basis, and will allow one to prevent emergency burner shutdowns due to lack of fuel.
The usual maintenance procedures for the burner also entail checking the combustion chamber condition of the warm air heater or boiler, in which the burner operates. The combustion chamber condition lets one determine, whether the combustion process is correct. A wet combustion chamber and dark colouring of the walls all point to bad combustion of the oil, while a dry chamber with a beige hue covering it indicates a correct combustion process.
These burners can be mounted to our waste oil boiler range or our waste oil warm air heater range , and make a great package solution.Please see our products page for more information on our waste oil heaters or waste oil boilers
