temperatures upto 250°C
Lab Hot air ovens are generally applicable for temperatures upto 250°C for treating chemicals and glassware in laboratories. Lab Hot Air Ovens also find a wide application in research institutions, industries, hospitals and R&D centers for various applications such as heating, drying & sterilizing.
The external Body / Frame of hot air ovens are made of mild steel / stainless steel depending upon the application based requirement, often with strong seamless welding and covered with a thick layer of stoved epoxy polyester paint. This provides a strong, highly screech and heat resistant surface for a long lasting attractive finish to the Hot air ovens. Internal surfaces (including the doors) of Hot air ovens are manufactured from either aluminum or stainless steel, with great care in order to eliminate sharp edges.
The double walled chamber of hot air ovens is filled with high grade insulation to prevent heat loss which is generally glass wool for ovens till maximum temperature of 250 degree Celsius. Elements of the hot air ovens are of the sheathed black heat type are put inside beads and placed at the bottom and in both the side ribs are placed for uniform temperature. The door of hot air oven closes on to an asbestos gasket the shelves slide neatly into the fixed runners. Fixed ventilators are provided on both sides of the Hot air oven's wall so as to control the ventilation of air as per operational requirement.
A Digital Microprocessor based PID Temperature Controller come display unit is provided on the top of Hot air oven to keep a constant check on the temperature which is being displayed on the seven segment L.E.D display and also to set the temperature range according to the requirement. The Hot air oven is mounted on four rubber foots to prevent slipping and this protects the bench surface. The control panel houses a main ON/OFF switch, LOAD ON/OFF Indicator lamps and A Digital Microprocessor based PID Temperature Controller come display unit.
Working Principle of Hot Air Oven is the forced circulation of hot air inside the chamber of oven. As it is a universal scientific fact that in any chamber hot air rises above, So by utilizing this principle when the hot air reaches the top of chamber it is circulated back to bottom by a fan installed inside the chamber and hence optimum amount of heat is achieved gradually inside the Hot Air Oven.
