Tenders Description & Specification for Hot Air Oven
Hot Air Oven UK, Kenya, China, Turkey, Thailand, Dubai and Malaysia
Utilizing forced air circulation, hot air ovens are used in laboratories to perform effect of ageing on various physical properties of any type of materials including yarns, fabrics and paper etc; in addition, these forced air convection ovens are also used for high quality drying and baking applications in the field of laboratory, medical or biomedical and pharmaceutical and textile industries, where fast heat up and consistent temperature are prime requisite. Often known as hot air circulating ovens, these units are fitted with blower or fan inside in order to distribute hot air (warm air) in every corner of the inner chamber. Physical properties of materials are analyzed before and after ageing in order to find out their suitability for specific applications.
Our hot air oven systems offer continuous temperature up to 250°C and feature safe operation; allowing operators to worry-free perform their tests. Standard models of our hot air ovens are available from 22 liters to 300 liters volume; however, we can design and manufacture hot air ovens meeting customer provided temperature range, sizes and capacities. There are various optional accessories that our company can add on extra cost in order to make your working more comfortable. Under economical price, our hot air ovens deliver superior quality drying facilities.

emperature:
All hot air ovens provide temperature range 5°C above ambient to 250°C with
accuracy of ±2°C. Temperature is controlled with mechanical temperature
control (rotary knob) or by digital control (PID controller). For
uniform rotation of heat inside the chamber noise-less fan is used for
air circulation.
Construction:
Each hot air
oven is produced with double walled construction and made of 304 grades
stainless steel with insulation of mineral wool for efficient thermal
loss. In economical models, exterior chamber is made of powder coated
MS, while 304 stainless steel is used as an option. Inner chamber is
completely made of stainless steel, which is easy to clean and maintain.
Shelves are made of painted steel and can be easily adjusted inside the
chamber with ribs created inside the interior chamber walls.
Doors:
Doors
are double walled, made of MS steel (stainless steel optional) and also
fully insulated with mineral wool, fitted on heavy hinges. Sturdy
handle provides comfortable opening and closing. Doors open 180° in
order to provide enough access to the heating chamber.
Heating Elements:
For
efficient heating, our hot air ovens are fitted with branded heating
elements, nickel / chrome plated nichrome wire, kept inside the beads
and placed at the bottom and both sides of the chamber.
Ventilation:
For safe removal of hot gases and fumes air ventilators are provided near the top of the both sides.
Safety Features:
For
safe operation of hot air oven, several safety instruments are fitted;
automatic circuit breaker turns off the unit in case of over temperature
and other short circuits. Audio and visual alarms can be fitted as
option, alert the user if temperature goes beyond the selection.
