Electric Models
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 heating element contactors electrically interlocked to shut off heaters if power to blower is interrupted and to permit operation of blower without heat for cooling. Alloy wire heating elements. Exhaust outlet 4″ diameter.
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. Automatic pre-ignition purge period and push button electric ignition contributes to ease of operation. Modulating gas burner is protected with electronic flame safety relay.
Combination Air Flow
These electric or gas models come in two sizes. They feature combination vertical and horizontal air flow for truck processing of various size parts at temperatures to 500°F.
TA Series Size 36″ x 36″ x 60″ high provides 45 cubic feet of work space. Truck tracks 2″ wide, 24″ center to center. Optional companion truck holds twelve 30″ x 30″ shelves on 4″ centers.
TB Series Size 48″ x 48″ x 60″ high provides 80 cubic feet of work space. Truck tracks 2″ wide, 36″ center to center. Optional companion truck holds twelve 42″ x 42″ shelves on 4″ centers.
Horizontal Air Flow
Similar to TA and TB Series, these electric or gas models feature full horizontal air flow with adjustable patented opposed louvers on full coverage supply and return duct work. Used when vertical air flow through the load is restricted. Ideal for processing flat sheets, pans of parts or when shelves are densely packed.
Capacity HP Outlet Diameter Height
80 CFM 1/8 4″ 16″
130 CFM 1/3 4″ 20″
325 CFM 1/3 6″ 23″
650 CFM 1/2 6″ 23″
