The new ACE (RT) Radiant Tube Heat Clean-ing Ovens are big on performance and havethe ultimate in energy savings, about 20%over convection-only Burn-Off ovens. ACEintroduces the radiant tube heater, which forthe first time utilizes radiant plus convectionheat. Heat from the radiant tube results in aconsequent heat extraction efficiency of 90%.Heats even in the harshest environment.

ACE HYBRID HEATING DESIGNThe (RT) system consists of a radiant tube,which directs the radiant energy upward. Theradiant tube is located under the oven cart. Itis positioned in the center of the oven andextends from the back wall to oven door. Agas burner fires directly into the length of theRadiant Tube. Convection heat evenly comesout the numerous holes on the left and rightside along the entire length of the RadiantTube. Radiant energy is also evenly emitted

OVEN DESIGNThe ACE Heat Cleaning Oven System is de-signed to remove varnish, epoxy, paint,grease, oil, rubber or other combustible mate-rials from metals. Heat clean motor stators,paint hooks, automotive engine parts, rubber-to-metal bonded parts, virtually any metalpart. The ACE system will also debond brakeshoes and clutch plates. Parts are loaded on awheel-in cart and heated to 650° - 800° F(340° - 427° C), in an oxygen deficient atmo-sphere, where the combustible hydrocarbonsdecompose. Parts leave the oven completelydry and ash residue is easily removed.

CONSTRUCTIONThe ACE Oven is fabricated from 11 gauge steeland coated with a high temperature, rustresistant paint. 4 inches of high temperatureinsulation rated at 2,300o F (1,260o C) lines theoven and self-supporting exhaust stack to offermaximum energy efficiency. The thick door issecurely sealed by husky cam type latchingmechanisms located on the top and bottom ofthe door. For reasons of safety, the latch isdesigned to accept a lock, as the door shouldnot be opened during the heating cycle.

ONE TOUCH CONTROL (OTC)OTC is a new automatic self-adjusting controlsystem. It monitors the combustible vapor inthe oven and controls them at a safe level.Requires no program selection by the operator,thus removes the possibility of operator error.An accurate, simple, yet highly effective systemto automatically provide the shortest possiblesafe heat cleaning cycle times. The OTCsystem automatically self adjusts the cycle timeto the weight of the non-combustible andcombustible load. Naturally, lightercombustible loads automatically take lessprocessing cycle time than heavier combustibleloads.

BURN OFF OVEN with ONE TOUCH CONTROL (OTC)The automatic self-adjusting system permits no margin-of-error for over or under processing. It does not require anexperienced operator to select a menu or estimate theamount of combustible material in the load. One touch ofthe start button, then let the OTC do the work for any sizeload.

HOW IT WORKSA digital temperature control is programmed at the factoryto heat your load on high fire in the shortest possible time.The primary and secondary water systems activate and orthe main burner goes to low fire to control the heat cycle ata safe rate. If the primary and back up secondary waterspray systems cannot control a rapid increase intemperature, the main burner will go to low fire. Theafterburner stays on, and both primary and secondarywater spray systems continue to operate until thetemperature is under control.

Rest assured, the OTC will not turn off the burners untilthere are no combustible materials remaining on the ovenload. When the load is done, the oven is automaticallyturned off by the OTC.OTC continuously monitors the heat-up rate of the ovenchamber. If it heats up too rapidly, indicating excessivecombustible vapor, the load is cooled by the water spraysystem or oven burner goes to low-fire until the heat-uprate is acceptable. The system starts workingimmediately after the process starts. Thus, controls areautomatically set for much faster processing time.

OTC is a successful system, because it has a “sixthsense”, a fast heat sensitive response time, whichanticipates and prevents excessive combustion vapor inthe oven at a safe level. It works on a principle calledthermoelectricity, in which extremely small heat variationscreates instant current flow to the OTC system.

OPTIONAs an option, should there be a power failure, the waterspray system is activated to cool down the load. Thus,helping to prevent smoke, fumes and odor emissionsfrom the exhaust stack. The water system isautomatically turned off when oven temperature dropsbelow 300°F. (149°C) to prevent flooding the oven.

COMPARISON OF (3) CONTROL SYSTEMSOTC has many important improvements over the otherthree commonly used control systems:(1) Ramp & Soak control, (2) Rate-Of-Change control and

(3) Batch Cycle Timer control.

2. Rate-Of-Change ControlOTC is not a rate-of-change control system thatcontinuously monitors the heat-up rate of both theoven chamber and the afterburner. OTC only hasone digital control. Our automatic self adjustingcontrol system’s “sixth sense” anticipates andprevents excessive combustion vapor in the ovenand controls it at a safe level. Vapors aregenerated in the oven and should rigidly becontrolled by one sensor in the oven and notshuttled off to yet another interfaced sensor in theafterburner.“Rate-of-change control requires two digitaltemperature controllers, one to monitor oventemperature and the other to monitor afterburnertemperature. The rate-of-change control system isa factory programmed system that continuouslymonitors heat-up rate of both the oven chamberand the afterburner. If either heats up too rapidly,indicating excessive combustible vapor, the load iscooled until the heat-up rate is acceptable.”Rate-of-change control requires two digitalcontrols, which are hard wire interfaced to shuttledata back and forth to monitor the temperaturerate-of-change of both the oven and afterburner.

3. Batch Cycle Timer ControlOTC is not a batch cycle timer control system. Abatch cycle timer is not installed in the OTCsystem. In the batch cycle timer system, anexperienced operator is required to select anestimated length of time the oven will run to dothe job. The operator could very easily under orover estimate the required processing time for theload. This could result in the oven prematurelyshutting off during processing, resulting in partiallycleaned loads, and emissions of smoke, fumes andodors out the exhaust stack. Extra timeinadvertently added to the cycle will result inwasted fuel and cycle time.

PATENT PENDING

Requires the operator to select the proper rampand soak profile program for the size load to beprocessed. OTC is not a Ramp & Soak controlsystem.OTC completely eliminates ramp & soakprofile programs in the controller for various sizeloads. OTC requires only one touch of the startbutton, then lets the OTC do the work for any sizeload. OTC does not require the operator to makeany decisions. It helps prevent operator error.OTC automatically adjusts to safely run any sizeload in the safest and shortest possible time.OTC continuously monitors the heat-up rate in theoven chamber during the entire cycle.OTC automatically turns off the oven when theload is done.
