HARSHAW Nearly every laboratory has requirements for ruggedly constructed, accurately controlled ovens for aging, conditioning, drying, pre-heating and various other applications. The "Precision"— Freas electric heat, automatically controlled, gravity and mechanical convection ovens provide for extremely wide variations in performance requirements. Cabinets are durable wall construction built on structural steel framework, mounted on a sturdy base with heavy, stamped steel legs welded to the outer walls. Cabinets are all metal, electrically welded with no screws or bolts. All doors are double walled and packed with a 3 " blanket of glass wool. Thermal insulation,
safe closing pressure latches insure tight closures, Bakélite handles stay cool. Inner and outer walls are braced by V-shaped struts, constructed so that heat losses are reduced to a minimum. A 3 " blanket of glass wool insulation is provided between the inner and outer walls. All wiring is fully enclosed, protected by either a sheet metal enclosure or conduit and outlet box fittings. The wiring, relays, switches, pilot lamps and auxiliary electrical devices are approved by the U. S. Underwriters Laboratories and meet the National Electrical Code.
