The product is widely used for hard baking and soft baking of wafer wafers, LCD、CMOS、IS、 Preheating, aging, baking, heat curing, quenching and stress relief processes in many industrial fields such as medicine, laboratory, aerospace, etc.

Clean oven Model:Class-270A/B

Product Features：

This equipment is a new type of industrial grade clean drying equipment, which adopts a unique internal and external compartment separation structure combined with an internal circulation air duct design. It continuously self purifies and filters the interior through a high temperature resistant and ultra high efficiency filter H.E.P.A, thus forming a high cleanliness, uniform temperature, and closed high-temperature hot air baking environment.

Load layer rack:The interlayer spacing can be adjusted according to the size of the item, resulting in high space utilization efficiency.

control system

★control panel:adoptPID automatic calculation, 7-inch touch screenScreen display, temperature, time、Curve and programmable segmentation settingsWaiting for parameters

Alarm function:Equipped with sensor disconnection alarm function and over temperature alarm protection function, ensuring the safe operation of the product

★heatTube:The heating tube is located on the back of the device (which can effectively prevent liquid droplets from falling onto the heating tube and causing detonation)

Air duct structure:

Air duct structure:The air duct adoptsBack ventilation, blowing air from all sides up and downEnsure temperature uniformity inside the box，adoptHigh density perforated wind panel.

Air supply device:Adopting high-power three-phase asynchronous high-temperature resistant long shaft silent motor+Large diameter stainless steel turbine blades, the turbine is horizontally corrected to ensure smooth airflow.

Air supply device safety protection system:Equipped with over temperature, overload and overcurrent protection function, ensuring the service life and safety performance of the motor and fan.

Electric heating system: using covered stainless steel dust-free electric heating generator, clean and dust-free.

Clean circulation system：

After using a flat horizontal rear air supply, it passes through a high temperature resistant and efficient filter H.E.P.A device toUp, down, and on both sides on all four sides(Special air duct design) directional air supply, 0.3um diameter PARTICLE, filtration efficiency of 99.97%, and the cleanliness inside the box can reach Class 100.

Exhaust port: (with automatic opening and closing damper) to achieve strong circulation effect and cooling.

Differential pressure gauge: Imported differential pressure gauge that can monitor the working status of H.E.P.A in real time.

Equipped with fully automatic switchrowThe air door is tightly closed during the baking process to ensure that the interior is sealed off from the outside and prevent external exhaustPARTYCLE dust return pollution

Security function:

Adopting an over temperature protection system to ensure the overall safety performance of the enclosure during operation.

Internal electrical protection system of the box (ensuring smooth, safe and reliable operation of electrical appliances inside the box):

Overtemperature preventer (independent temperature limit, power outage due to overheating);

Phase sequence protection (under voltage and under phase protection);

Motor overcurrent protection;

Control circuit fuse;

Electric heating overcurrent protection;

No fuse switch.
