WALK IN OVENS
1) HIGH TEMPERATURE WALK IN OVEN
For annealing, sintering, precipitation hardening, burn off or any other high temperature processing of large or numerous parts. Constructed with an isolated inner oven to eliminate heat transfer and leakage at seams commonly found in standard panel construction. Designed and constructed for long, hard, continuous use with the temperature uniformity required for consistent results at elevated temperatures.

Other electrical characteristics available
- All Models
Exclusive construction is far superior to commonly used panel construction Consists of an isolated inner oven completely surrounded by insulation to eliminate heat transfer from through metal and hot air leakage at panel seams. Insulated floor standard. Trilite Green enamel painted aluminized steel exterior.
- Electric Models
each features completely wired, side access control panel enclosing terminals for incoming power temperature controllers, push buttons and heating element contactors electrically interlocked to shut off heat for cooling. Incoloy sheathed tubular heating elements on all models. The 6500C models have a heat chamber high limit control.
- Gas Models
1,000 BTU natural gas at 6″ water column pressure 1″ NPT inlet
other gas characteristics available
Control panel as detailed above and safety devices as listed on the front of this bulletin. A 325 CFM powered forced exhauster in included up to 800,000 BTU/HR, at 880,000 BTU/HR a 650 CFM exhauster is included. Both exhausters have 6″ outlets. Automatic preignition purge period and push button electric ignition contributes to ease of operation. Modulating gas burner is protected with electronic flame safety relay.
