PCPC InertGas Controlled Pyrolysis - Oxidation Control Cleaning Furnaces
The ultimate in safety, Pollution Control`s patented inert gas oven models can handle any combustible that can legally be removed with heat, even space age engineered plastics and polymers. PCPC`s InertGas ovens (U.S. Patent 4,557,203) expand the Controlled Pyrolysis® process with enhanced cleaning capabilities. InertGas furnaces leave the primary burner on during the initial "pyrolysis" stage of the cleaning cycle to produce an oxygen-deficient atmosphere inside the furnace (10% oxygen versus the usual 21% as in the air). Lower oxygen eliminates the danger of fire and allows for the safe processing of highly combustible materials in large volumes.

InertGas Ovens
- For parts with up to 50% combustibles
- Maximum 900°F (482°C)
During this initial "pyrolysis" stage, the IntertGas furnace temperature controller and the stack temperature controller each operate double water spray mists at double set-points for maximum protection. During the final "oxidation" stage of the process, the primary burner cycles on and off, increasing the oxygen level in the oven to completely oxidize any remaining char or carbon off the parts.
- Save labor cost
- Full compliance with EPA regulations
- Eliminate your employee exposure to injury
- Gentle process that extends the life of your tooling
- Quick cycle times
- Inexpensive utility costs
- Fully automatic and self-adjusting cleaning cycle
- Simple-clean process with no splattering or mess
- 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 800ºF (427ºC). 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.
- Automatic Time Cycles run the furnace only as long as it takes to process the load.
- Fully Automatic no cycle time or ramp recipe to select.
- Automatic Cool-Down if secondary burner fails during a cycle.
- 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.
- Door Switch, Purge Timer, Extra Gas Valve and High/Low Gas Pressure Switches enhance burner safety that may be required by some insurers.

Specifications and Data
- Cabinet: Heavy Gauge sheet steel supported by structural steel angles and channels, and covered by heavy-gauge sheet metal shell.
- Floor: Hard castable refractory, reinforced with structural steel channels. Allows easy removal of ashes.
- Doors: Equipped with cam-type lock assemblies and tadpole stealing gaskets. Door opens 95°.
- Explosion Relief: Unique gravity sealed top relief door automatically opens to relieve excess pressure, then closes, preventing air from reacting with combustible material.
- Insulation: Walls and ceilings are covered with 4? of a two layer light weight ceramic fiber insulation and 1/8? vapor barrier to prevent corrosion. Perforated metal liner protects insulation. Hot face insulation rated at 2300°F (120°C)
