A Revolutionary Boiler Design

OMNI's unique design provides high efficiency. The OMNI cast iron boiler is a revolutionary idea in industrial heating. It utilizes the highly efficient, extremely durable Scotch Marine design principle that has been proven in decades of use in large commercial and industrial heating systems. Boiler is manufactured in Germany, and sections are assembled there as well.

Waste oil boiler Designed For Easy Maintenance

Easy to Maintain

Swing out door and rear cleanout ports allow money saving serviceability. Unlike traditional boilers which require hours of disassembly, the OMNI's hinged front door provides instant access to all of the boilers' heat transfer surfaces. All service and cleaning can be completed literally in minutes, creating additional savings.
A clean boiler is a more efficient boiler.


Compare the OMNI 3 Pass Design
The OMNI Three Pass Design
 This unique wet base design passes the hot combustion gases three times through the boiler under negative pressure. This maximizes the gases contact with the boiler's water surface area. The result: 84% Efficiency, Burns Clean, Zero Smoke
Conventional One Pass Design
 Competitor's Designs
Our competitor's conventional one-pass design is less efficient and requires time-consuming, cumbersome disassembly of parts for cleaning.

 

Long burn path combined with scotch marine triple pass design provides the best combination of high efficiency and super-low maintenance.
Stainless steel chamber is standard. OMNI waste oil boilers feature high grade stainless steel combustion chamber liner. Stainless steel is the longest lasting, most durable material available for high temperature applications of waste oil burning. This liner creates a secondary burn resulting in a more thorough burn - less ash build up.
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.
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. Large boilers come equiped with flue brushes.
Full access clean out door. OMNI provides complete access to the inside of heat exchanger and combustion chamber through our full clean out panel. Other manufacturers provide only limited access or require clean out of exchangers which are too small to thoroughly reach.
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 stat 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.
