利用强制空气循环,热风烤箱基于“增大化现实”技术e 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也用于实验室，医疗或生物医学和制药和制药和纺织工业领域的高品质干燥和烘焙应用，其中快速加热和一致的温度是主要的必要条件。通常称为热空气循环烤箱，这些单元配有鼓风机或风扇内部，以便在内腔的每个角落分布热空气（暖空气）。在老化之前和之后分析材料的物理性质，以便找出它们对特定应用的适用性。

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 from22 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.

高度：
所有热空气烤箱都提供温度范围5°C above ambient to 250°Cwith 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.

建造：
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.
