PCPC Controlled Pyrolysis - Burn-Off Oven

• Controlled Pyrolysis Ovens
• For parts with up to 15% combustibles
• Maximum 800°F (427°C)

Located in the afterburner stack, this sensitive system (U.S. Patent 4,270,898) monitors the rate of smoke emission from the parts by measuring the stack temperature. When the stack temperature reaches a preset point, the stack controller turns on a water spray mist to cool the parts, lowering the smoke emission rate before it reaches an ignition state. The water spray also activates if the oven temperature exceeds its set-point temperature by 30°. A back-up water spray activates should the water spray nozzles become clogged or malfunction in any way. Additionally, a manual-reset high-limit temperature controller turns off the primary burner if the oven temperature controller should fail.

• Controlled pyrolysis cleaning furnaces provide a safe process that helps to clean and extend the life of your industrial parts in a method that doesn`t pollute or harm the environment.
• Our controlled pyrolysis ovens eliminate hydro-carbon emissions and the use of hazardous chemicals and abrasives.
• The control system is easy to operate and helps to ensure safe and thorough cleaning with reduced labor costs to you.

• Auto-Parts and Engine Rebuilding
• Reclaiming Diesel Particulate Filters
• Paint & Powder Coating
• Oil & Gas

• Patented Controlled Pyrolysis^® Water Spray System controls the rate of smoke emissions preventing damage due to ignition or over-heated in the furnace.
• The Primary Burner heats the cleaning chamber to 800°F (427°C). Volatile materials are driven off as smoke. The burner flame is confined to the combustion chamber never touching the parts.
  
• Back-Up Water Spray if nozzles are clogged.
  
• Manual-reset high-limit switch
• Diagnostic Panel indicator lights reflect the operational status of the oven and its controls. Indicator light failure pin-points the problem

Controlled Pyrolysis^® Model Features

• Patented Controlled Pyrolysis^® Water Spray System controls the rate of smoke emissions preventing damage due to ignition or over-heated in the furnace. Standard
• Optional Burners available:
  1. Natural Gas
  2. Propane Gas
  3. Number 2 Fuel Oil
• The Primary Burner heats the cleaning chamber to 800°F (427°C). Volatile materials are driven off as smoke. The burner flame is confined to the combustion chamber never touching the parts. Standard
• Back-Up Water Spray if nozzles are clogged. Standard
• Manual-reset high-limit switch Standard
• The Afterburner operating at 1400°F (760°C) for ½ second burns the smoke consuming the pollutants, leaving only invisible, odorless and harmless water vapor and carbon dioxide to exit the exhaust stack.
• Explosion Relief Door(s) automatically opens to relieve excess pressure then closes preventing air from reaching combustible materials.
• Diagnostic Panel indicator lights reflect the operational status of the oven and its controls. Indicator light failure pin-points the problem. Standard

Specifications and Data
