OMNI waste oil heaters do not requiring constant cleaning and adjustments. |
|
|
OMNI burns fuels from kerosene to 90W gear oil (including synthetics). OMNI's hands-off system combines our patented oil preheat and oil flow control to burn a wider range of fuel than other waste oil burners, with no adjustments. |
|
Highest quality heaters/boilers/air conditioners on the market. OMNI's advanced design, high level of quality and craftsmanship combine to make OMNI the premier unit in the industry today. |
|
State of the art, solid state Oil Preheat System. OMNI's patented system provides consistent oil temperature and viscosity to the burner. Solid state controls allow only a 3° variance in oil temperature. This maintains oil viscosity and results in the most thorough, clean and consistent burn available. Other manufacturers' mechanical preheat systems allow large temperature variances which cause varied fuel viscosity and inconsistent flame in combustion chamber, resulting in uneven heat and quicker failure of chamber. |
|
Preheater heats both oil and air at the same time for optimum atomization (spray) and completeness of burn. |
|
Electronic oil shut off valve eliminates nozzle drip - won't allow stalagmite of sludge at the bottom of the chamber. |
|
Patented Oil Preheat System ELIMINATES the need for routine disassembly of your burner to scrape out carbon build up in the oil heat block. OMNI's patented oil preheater uses advanced technology to eliminate the need for cleaning. Our superior design will not carbon. OMNI is the only manufacturer that can say this! |
|
Built-in air compressor. OMNI includes a built-in vane oil-less compressor as standard equipment. Our compressor requires no maintenance and allows the unit to be operated 24 hours/day without an external air supply. You eliminate the risk of destroying a shop air compressor if an air line were to rupture. |
|
Long burn path provides high efficiency and eliminates the need for a target wall. OMNI waste oil burners are up to 85% efficient. Our long combustion chamber burn path and oil flow control capabilities eliminate the need for a target wall. With others, target walls are subject to direct exposure to flame and extreme temperature changes which destroy the target and require them to be replaced frequently. |
|
Stainless steel heat exchanger is standard. OMNI waste oil furnaces feature high grade stainless steel heat exchangers. Stainless steel is the longest lasting, most durable material available for high temperature applications. Other manufacturers use lower cost materials and try to compensate with thicker walls of inferior steel. |
|
Patented Oil Flow System controls fuel by volume. OMNI's patented flow control system regulates fuel by volume. Conventional waste oil burners use a preset pump and control fuel delivery with a fuel pressure regulator. This conventional system creates variable to fuel flow and cause over and under firing. |
|
12 Year Warranty. OMNI waste oil furnaces are so reliable that they are backed by a 12 year non-prorated warranty. |
|
Swing out burner. Allows easy access for cleaning of burner nozzle and end cone if needed. Combustion chamber annual clean out is easy. OMNI provides complete access to inside of combustion chamber and heat exchangers with the largest openings in the industry. |
|
Full access clean out panel. OMNI provides complete access to the inside of heat exchanger and combustion chamber through our full length clean out panel. Other manufacturers provide only limited access or require clean out of exchangers that are too small to thoroughly reach. |

![]() ![]() Flame Control System The OMNI Flame Control System is a patented system that consists of an Oil Flow Supply Pump and a Non-Carboning Oil Preheater that controls the fuel by volume. The Flame Control System can be purchased separately with a universal burner mounting flange allows easy retrofit of our burner system to various configuration and sizes of combustion chambers. Initial flame adjustment is all that is needed with complete control thereafter. Flame Control System Benefits:
Single Burner Does it All! * Burner can be purchased separately! *
Omni includes a built-in vane oil-less compressor as standard equipment.
Swing out burner door, no fuel or air lines to disconnect. Removal of one nut and electrical safety plug allows easy access to flame end cone and nozzle for quick service.
The Industry's ONLY Non-Carboning Oil Preheater Block
with a These items precisely control the oil and air temperatures to insure stable viscosity for optimum control of the flame resulting in a thorough burn. Heater block never carbons or needs to be removed for cleaning. Industry normal annual parts kit not needed with OMNI's system! Readjustment of electrodes and nozzle replacement every 5 years is all that is needed due to erosion only.
Our Heat Exchangers consist of formed 304L 16 Ga. Stainless steel plates with have a double rolled pressed seam. This pressed seam construction eliminates the possibility of stress cracks that can occur from welding.
High Volume Fans
Easy Access For Pass Through Cleaning.
Our long combustion chamber burn path and oil flow control capabilities eliminate the need for a target wall. With others, target walls are subject to direct exposure to flame and extreme temperature changes with destroy the target and require them to be replaced frequently. Burns Clean – Zero Smoke. |
