Heats up to 550 F.

A 550 F, electrically-heated, universal style oven from Grieve Corp., Round Lake, Ill., is for preheating acrylic and polycarbonate sheets prior to forming.  Workspace dimensions of Grieve’s No. 1026 oven measure 34-in wide x 120-in. deep x 48-in. high.   The oven chamber is heated by 60KW Incoloy-sheathed tubular elements, while a 4200 cfm, 3-hp recirculating blower provides horizontal, front to rear airflow to the workload. 

The oven has 6-in. insulated walls, aluminized steel exterior, Type 304, 2B finish stainless steel interior and four front access doors with automatic door switches to shut off the heat and blower when a door is opened.  Four structural steel slide beds are provided to support the plastic sheets during processing.  

Controls on the 1026 include a digital indicating temperature controller, manual reset excess temperature controller with separate contactors, recirculating blower airflow safety switch, SCR power controller and eight auxiliary thermocouples connected to a selector switch
