With OGR

Introducing The OGR Solution from Biozone Scientific

The OGR solution is an automated, chemical-free treatment system that reduces the accumulation of grease, oil, and unwanted food odors from commercial and industrial kitchens.

The OGR solution combines the power of ultraviolet oxidation and UV photolysis to prevent the accumulation of oil and grease particles while eliminating food odors in kitchen exhaust systems.

If your customers can benefit from an automated, chemical-free cleaning system for their kitchen hoods and ductwork,

A Powerful Technology Ingredient

The latest technology saves your customers’ maintenance costs and reduces the time they will spend on manual cleaning. 

OGR reduces the risk of dangerous fire hazards, kitchen odors, and cooking emissions.

New construction and upgrades to existing cooking facilities can benefit from including OGR.

The OGR solution amplifies the working efficiency and lifetime of any hood and ventilation system, and is the perfect complementary technology to kitchen hood baffles.

Would your customers benefit from being prepared for inspections, every single day?

The Patented Biozone Advantage

Ultraviolet light is one of Nature’s most powerful and effective disinfectants, perfectly designed to destroy odors, bacteria, viruses, mold, and mildew, and to break down unwanted chemicals and compounds.

Biozone’s patented solutions use a mix of technologies, including UV light and plasma, oxidize grease particles in the hood and throughout the duct.

The solution is exceptionally effective against grease particles too small to be captured by baffles, ensuring complete treatment for the entire system.

How OGR Works

Large particles of grease and oil rising from the grill can be effectively captured and stopped by the baffles in the kitchen hood.

Small particles, however, are borne upward by the flow of the exhaust air stream, past the baffles.

The OGR solution oxidizes grease and oil particles which are too small to be captured effectively by baffles, turning dangerous, flammable material into small amounts of low-combustion ash, easily wiped off at the end of the day.

The OGR system immediately reduces airborne pollutants, grease, kitchen oils, and other chemicals by up to 95%, reducing the burden on ventilation systems and lowering the risk of dangerous kitchen fires.

Agencies such as the United States EPA, FDA, and ASHRAE approve ultraviolet technologies like OGR for industrial and commercial applications providing disinfection and sanitation.

Baffles and UV: Complementary Technologies

This graphic shows how kitchen hood baffles (a type of mechanical air filtration) and the OGR solution (the leading ultraviolet light system) can be used together to capture a majority of airborne grease and oil.

When used alone, baffles are effective at capturing large particles of grease and oil, but less effective at capturing smaller airborne particles.

The OGR solution can reduce the amount of grease and oil particles which pass the kitchen hood baffle by


A Solution for Every Kitchen Hood

The OGR system is made up of components which can be customized for any kitchen hood and duct combination.

It is available as a standard system and also as an OEM solution.

Designed for simplicity, several of the system components are serviceable by the end user.  This includes replacement of the ultraviolet bulbs themselves, available from Biozone.
