With a deep commitment to the global market, Shanghai Dengsheng Instruments has earned international acclaim for its quality.






Explosion-proof ovens, also known as explosion-proof drying cabinets, are primarily used in military systems, nuclear industries, aerospace systems, factories affiliated with the Ministry of Machinery and military bases, civil explosives industries, chemical industries, pharmaceutical manufacturing, paint and coating industries, research institutes, and university laboratories. They serve to dry various powders, cure surface coatings on products, dry detonator components in military enterprises, conduct aging tests on electronic components, and dry microporous products and biomedical products.
1. The product meets the IIB explosion-proof standard and is suitable for hazardous locations with explosive gas mixtures in temperature classes T1 to T4. It achieves an explosion-proof rating of IIB T4. The product has been certified by the ****** Electrical Safety Quality Inspection and Testing Center and issued with the ********* Explosion-Proof Certificate.
2. The electrical control system employs a combination of flameproof and intrinsically safe explosion-proof technologies. The operation switch is a passive switch that generates no mechanical sparks during operation, ensuring safe and reliable use. The sensor is equipped with an external safety barrier for explosion-proof isolation.
3. The explosion-proof digital temperature controller features a menu-driven interface displaying set temperature, operating temperature, constant-temperature duration, and heating status on a single screen for intuitive operation. Its microcomputer PID control system ensures precise temperature regulation with minimal fluctuation;
4. Equipped with self-diagnostic startup, temperature calibration, over-temperature alarm, timer setting, and parameter memory functions;
5. Built-in over-temperature protection automatically cuts off heating power when temperature exceeds set value, ensuring safe and stable operation;
6. Insulation between the working chamber and outer casing uses flame-retardant fiberglass material. Thickened insulation layers achieve ideal thermal insulation, minimizing internal heat loss for energy efficiency;
7. Door seals are crafted from custom silicone rubber composite material, featuring high-temperature resistance, anti-aging properties, and minimal deformation. Excellent sealing prevents heat loss, achieving energy-saving objectives;
8. Features a proprietary hot air circulation system with high-temperature resistant explosion-proof fans and multi-wing centrifugal impellers. Circulating air passes through multi-fin cast explosion-proof stainless steel heating tubes into the chamber, flows over the dried workpieces, and is drawn into the opposite duct, forming a closed-loop system. This ensures stable and efficient airflow, significantly improving temperature uniformity within the chamber;
9. Rapid heating rate with built-in forced air circulation. Heated air is forcibly circulated through proprietary ducts to the test specimens, significantly reducing drying time and accelerating testing processes;
10. The outer shell is constructed from cold-rolled steel plate with an advanced electrostatic powder coating finish that resists fading and static electricity. The inner chamber features premium 304 stainless steel with a thickness of 1.2mm and rounded corners for easy cleaning. Multiple adjustable shelves are provided inside the chamber with customizable spacing.
