Controlled Pyrolysis® Models
Available from Pollution Control Products Co.
For parts with up to 15% combustibles.
Maximum 800ºF, 427ºC
Controlled Pyrolysis® models can remove the same combustible materials as Dry Cleaner models but in greater quantities, 2 to 15% by weight. These models have a much more sensitive control system, (covered by U.S. Patent 4,270,898) located in the afterburner stack. That system monitors the rate of smoke emission from the parts by measuring the stack temperature. Any increase in smoke emission raises the stack temperature. When the stack temperature reaches a preset point, the stack controller turns on water spray mist to cool the parts, lowering the smoke emission rate before the smoke can reach an ignition state inside the oven’s cleaning chamber. The water spray system also operates if the oven temperature exceeds its set-point temperature by 30°. A separate back-up water spray turns on should the main water spray nozzles become clogged. A manual-reset high-limit temperature controller turns off the primary burner if the oven temperature controller should fail.
