HOT AIR OVEN HIGH TEMP-STI-278/ STI-279

PRODUCT APPRAISAL/APPLICATION

High Temperature Hot Air Oven is elegantly designed and fabricated to suit various applications in ever-growing field of Medical, Agricultural and Industrial Research, for day to day heating, drying, sterilizing, baking etc., in Laboratories, Hospitals & Industries.

BASIC CONSTRUCTION

High Temperature Hot Air Oven is a Triple Walled unit. Outer Chamber/body of the hot air oven is fabricated out of thick Mild Steel Sheet/PCRC sheet duly/Galvanized Iron Steel Sheet duly pre-treated with primers for rust proofing and durably painted with long lasting powder coating paint. The inner chamber is made of heavy gauge high Grade Stainless Steel Sheet and intervening wall of Mild Steel/Galvanized Iron sheet. The gap between the walls is filled with special grade mineral glass wool, which ensures maximum thermal efficiency in laboratory ovens. Inner chamber of the hot air oven is incorporated with ribs for placing the shelves or trays at convenient levels. Door is lined with quality Gasket & provided with the best Handle. Air Ventilators are placed near the top of the both sides to remove hot gases and fumes if any. The unit is provided with one to three stainless steel Wire Mesh shelves/Ms shelves depending upon the size of the Inner Chamber. Unit is provided with an efficient Heavy duty Motorized blower which results in uniform temperature at any point inside the working chamber.

TEMPERATURE CONTROL

HEATING

An efficient Heating system is provided in the unit. Heating in the chambers is achieved by means of Quality Air heaters of suitable wattage. Heating elements are placed in the path of moving air duly insulated from the body. To ensure utmost temperature sensitivity the warm air is evenly distributed throughout the chamber through Heavy Duty Motorized Blower unit.
