Hot air ovens are designed to generate heat with the help of a fan recirculating the air inside the chamber at a temperature from ambient +10 C to 150 C, 200 C, or 250 C. They are also generally called forced air ovens and are widely used for drying glassware, sterilizing N95 masks, general instruments, and packaging items.Specifications:Construction: Double WalledInner Chamber: Made Of Stainless Steel 304 Grade.Outer Chamber: Made Of Mild Steel And Finished With Powder Coated.Insulation: Gap Between Inner And Outer Chamber Is Filled With Glass Wool Insulation.Trays: Two Stainless Steel Trays Included.The Motorized Forced Air Circulation To Maintain Uniformity Inside The Chamber.Temperature Range: 5c Above Ambient To 200c With Accuracy +/- 2c.Power Supply: 230volts Single Phase 50hz, Ac Supply.Temperature Control: By Microprocessor Based Pid Controller With Dual Display (process Value And Set Value), Low And High Limit Setting, And Cral ThermocoupleCapacity in Liters: 42Inner chamber size [WXDXH] CMS: 35X35X35Capacity in Liters: 90Inner chamber size [WXDXH] CMS:45X45X45Capacity in Liters: 120Inner chamber size [WXDXH] CMS: 45X45X60Capacity in Liters: 210Inner chamber size [WXDXH] CMS: 60X60X60Capacity in Liters: 320Inner chamber size [WXDXH] CMS: 60X60X90
