Jd-8002 Temperature And Humidity Box Heating Time ≤5-8 °c/min High Temperature Oven
 
 
Manufacturing Overview:
 
The high temperature safety oven is designed and manufactured according to the national standard (JB/T 5520-91 drying box technical conditions), and is widely used in petroleum, chemical, composite materials, electronics, medical pharmacy, scientific research laboratories and other related production and research fields. Used for drying, baking, heat treatment, etc. of articles. This device has the following basic features:
 Adopt centrifugal multi-wing fan circulation system, unique air duct structure, stable temperature control and uniform temperature field. The manufacturing process specification is beautiful in appearance, convenient in operation and maintenance, and the buyer only needs to provide power and meet the required working environment.
 The matching of components and assembly is good. The main functional components are all original parts with international advanced level.
The temperature adopts intelligent digital display temperature control system. The control system adopts digital display and has PID control function. It can realize automatic operation of test program, and can automatically combine subsystems such as heating and fan to ensure high quality control of the whole temperature system. .
 Designed with a safe venting hole, located at the rear of the box, can automatically discharge pressure when the gas expands in the working chamber, to avoid damage to the door when the gas inside the studio expands and further damage the staff.
 The control system is equipped with a stand-alone digital over-temperature power-off protection system, which can be used with confidence when unattended.
 Configure high temperature resistant graphite sealing strips, humanized environmental awareness, and protect the health of users.
 
 
First, the main technical indicators:
 

 
Second, the room structure characteristics:
2.1 Structure: The horizontal integrated structure is used, and the control operating system is located on the upper side of the studio.
2.2 Box outer wall material: It is made of 1.5mm cold-rolled steel plate, and the outer surface is electrostatically sprayed;
2.3 Box body wall material: made of 304 stainless steel plate;
2.4 Gate and insulation sealing material: single door, high density asbestos,
2.5 partition: 2 layers, adjustable up and down;
 
 
Third, the air conditioning system:
3.1 Temperature control mode: Balanced temperature regulation (BTC), temperature difference with temperature control mode (TB). The method not only controls the output of the heater through the PID automatic calculation output according to the set temperature point, but also compensates for the heat loss, and finally achieves a dynamic balance control method.
3.2 Air circulation device: There are 2 high-temperature resistant stainless steel long-axis centrifugal multi-wing fans in the air conditioning room. The unique air duct forced closed circulation mode is used to push the circulating airflow through the heater to the working chamber, which greatly improves the air flow. And heat exchange capacity with the heater, thereby greatly improving the temperature uniformity.
3.3 Air heating mode: stainless steel closed electric heating tube, non-contact control (solid state relay).
