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.
FEATURES:PATENTED CONTROLLED PYROLYSIS® water spray system controls the rate of smoke emissions which prevents an ignition or overheat condition in the furnace.BURNERS AVAILABLE for:1. Natural Gas2. Propane Gas3. Number 2 Fuel OilPRIMARY BURNER heats the metal parts to 800°F (427°C). The volatile materials are driven off as smoke. Burner flame is confined to combustion chamber never touching the parts.SECONDARY BURNER raises the temperature of the smoke to 1400°F (760°C) for 1/2 second to completely burn it before discharging it to the atmosphere. 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. Failure of an indicator light to illuminate can help you pinpoint oven operation problems.EXHAUST EFFLUENT consists primarily of carbon dioxide and water vapor which are invisible, odorless and harmless.
