PRM has been manufacturing oxidizers for the remediation market for over 10 years. Our designs are safety first and are consistant.

With NFPA 86, the maximum loading allowable of VOCs in an oxidizer is 25% of the LEL. With CEM equipment, the allowance is up to 50% loading.

Electric Oxidizers:

PRM offers both Electric Catalytic and Catalytic Convertible Thermal Oxidizers. For remediation projects, the Electric oxidizers have shown that they operate more efficiently than do Gas fired units and uptime is usually much higher.

For sites that will have high initial concentrations, PRM asks that you consider the overall site loading over the course of time. Usually when an electric unit is installed on a hot site, the system is tuned back during the first month to allow for a steady state of influent VOCs to the oxidizer. Over 90% of hot sites are ran more efficiently with the Electric Units.

Electric Catalytic Oxidizers:

PRM manufactures Electric Catalytic oxidizers for destruction of VOCs from off gas equipment. The CatOx-E electric  unit offers destruction efficiencies to 99.99% destruction using the latest monolithic low temperature catalyst modules. All PRM CatOx-E catalytic oxidizers are manufactured of T304 Stainless Steel. The entire inner shell, heat exchanger and ducting are manufactured from T304 SS. 6" of insulating refractory material keeps the heat inside and the outer shell cool to the touch.

PRM catalyst modules are provided by Sud Chemie Prototech and offer superior catalytic destruction given their excellent cell density of 400cpi (cells per inch With a 70% preheat efficient heat exchanger standard, the CatOx-E  unitoffer the most energy efficient means of VOC destruction available on the market.  CatOx-E  units offer the ease of maintenance and also much higher "UPTIME" than is available with any other type of oxidizer, whether it is a  thermal or catalytic design.

Unlike gas fired units which have a difficult time responding to slugs, the CatOx-E unit is available with a 3-way valve that is easily implemented with SVE or dual phase blowers. . Please call our technical team to discuss the proper Oxidizer for your application.

Key Benefits:

• All electric
• 5-10 minute preheat time (maximum)
• 70% preheat efficient heat exchanger
• No hassles with gas supplies (natural or propane)
• Automatic restart on power failure
• LEL sensors and strip chart recorders available
• Ability to replace or add catalyst modules in less than 30 minutes
• Much lower liabilities than gas fired units as  these units are  flameless
• Optional web-based monitoring to read, log temperatures and air flow. Much more reliable than chart recorders.

Thermal Oxidizers:

Gas Fired Thermal Oxidizers are typically used for destruction of higher concentrations of VOCs. When operated in a straight thermal mode, the units are fired to 1400F and retention times are 1.5 seconds. Destruction is typically >99.999% for VOCs. When operated in catalytic mode, the units are fired to 700F and destruction is typically >99%. PRM uses a unique 90 degree burner tube and we crossfire the inlet fume directly into the most intent flame of the burner. Cross firing is done where there is no potential for creation of erratic flame. Cross firing of the fume into the burner provides destruction that other oxidizers do not obtain.

PRM Gas Fired Thermal Oxidizers are the safest oxidizers on the market. We go to additional steps to ensure safety. These safety steps are invisible to the operator as the PLC controller is providing background scans at an extremely rapid pace, looking for potential problems.

Key Benefits:

• 6" Thermal refractory lining, 8" refractory under exhaust stack
• Cylindrical design for equalized flow distribution
• SS exhaust stack with zero loss rain shield stack and sample port
• Skid mounted units with integral control panel
