These Class 100 ovens come in five sizes and include insulated floors with removable truck wheel guide tracks. They feature full horizontal air flow and adjustable opposed louvers on full coverage supply and return duct work. Easily removable
interior duct work for cleaning.

Each features completely wired, side access UL listed control panel enclosing terminals for incoming power, temperature controllers, push buttons and pilot lights. Motor starter and solid state heating element relay electrically interlocked to shut off heaters if power to blower is interrupted and to permit operation of blower without heat for cooling. Incoloy sheathed tubular heating elements. Exhaust outlet 4" diameter.

Stainless steel (type 304, 2B finish) interior with continuously back-welded seams. Recirculated air flow is continuously passed through high temperature HEPA filters to remove particles. High temperature HEPA filters have stainless steel housing and are 99.97% efficient on 0.3 micron particles.

Mechanical enclosure covers recirculating blower motor, heating element terminal box, air flow safety switch and other components to provide continuous exterior surface for easy cleaning.

Outer door cover and control panel face constructed from #4 brushed finish, type 304 stainless steel. Aluminized steel exterior finished with white epoxy enamel paint.

Optional loading trucks hold nine(9) shelves on 6" vertical centers and are all welded stainless steel construction including stainless steel casters. Loading trucks are moved to and from oven on optional transfer dollies.
