Explosion-proof instruments and equipment are essential products for modern industrial safety systems. They are specifically designed and manufactured for high-risk environments such as chemical, petroleum, military, aerospace, and pharmaceutical industries. Explosion-proof equipment integrates multiple technologies including flameproofing, potting, intrinsic safety, and inerting protection, achieving stable and reliable operation in high-temperature, flammable and explosive gas, or dust environments, fundamentally eliminating the risk of explosion and ensuring the safety of personnel and assets. Its technological foundation is built upon a multi-layered active and passive safety architecture. Key equipment such as drying ovens and test chambers utilize reinforced alloy steel bodies and specially designed sealing components to form a robust explosion-proof enclosure, effectively withstanding and isolating any potential internal arcs or sparks. Furthermore, for equipment like explosion-proof fans and air ventilators… Fans and air conditioners, which drive air circulation and temperature regulation, employ fully enclosed explosion-proof motors and spark-free blade designs to ensure that no electric arcs or static electricity accumulation, which could serve as ignition sources, are generated during continuous operation. Explosion-proof vacuum chambers create a low-pressure environment to remove oxygen, while some models of drying ovens are equipped with positive-pressure nitrogen filling systems that continuously inject inert gas into the chamber, forming and maintaining a slightly positive pressure safety zone higher than the external pressure, thereby physically preventing the infiltration of external flammable gases. Explosion-proof high and low temperature test chambers can absolutely guarantee the safe inertia of the internal environment while simulating extreme temperature conditions. Explosion-proof water baths provide a safe and stable heat source platform for the constant-temperature heating of flammable solvents. All of these devices have passed rigorous international explosion-proof certifications (such as CNAS), and their intelligent control systems integrate temperature sensors, pressure monitors, and fault self-diagnosis protocols, enabling all-weather safety status tracking and early warning. This ensures risk-free and high-precision production processes in critical fields such as petrochemicals, pharmaceutical synthesis, aerospace, military manufacturing, and hazardous chemical storage, even when facing the most complex process challenges. Explosion-proof instruments and equipment are not only environmentally adaptable devices, but also core nodes in modern industrial intelligent safety management and key infrastructure for the "inherent safety" concept.

Shanghai Dengsheng Instrument Manufacturing Co., Ltd. is a high-tech enterprise specializing in the design and production of Explosion-proof Series manufacturer equipment. Our range covers forced-air drying ovens, vacuum drying ovens, constant temperature and humidity chambers, high and low temperature test chambers, water baths, vacuum pumps, fans, blowers, and air conditioners—all engineered for hazardous zones where flammable gases, vapors, or dust are present.
We build these units in our 8,000-square-meter production facility with in-house sheet metal processing, welding, painting, and electrical assembly. Our R&D team holds 23 national patents, and our quality system is ISO-9001 certified. Every explosion-proof unit is designed to meet the national GBT 3836.1-2021 standard and is available with IIBT4 or IIB T1-T6 ratings, depending on the model and your process requirements.
Our Explosion-proof Series covers nine core product types, each matched to a specific thermal or environmental process. We configure the working chamber size, temperature range, and control options to your application.
These units are used in petrochemical, pharmaceutical synthesis, aerospace, military, and hazardous chemical storage facilities. The choice of product type depends on the process: whether you need drying under vacuum, forced convection, humidity control, or thermal cycling.
For example, an explosion-proof vacuum drying oven is ideal for removing solvents from powders or components that oxidize easily, while a forced-air oven suits bulk drying of non-heat-sensitive parts. Constant temperature and humidity chambers are used for long-term stability testing of electronics or materials in flammable atmospheres.
We also consider the chemical compatibility of the chamber interior. Standard interiors use 304 stainless steel with rounded corners for easy cleaning. For aggressive solvents, we can specify fluororubber seals or additional surface treatments to resist corrosion and static buildup.
Our explosion-proof design follows a multi-layered approach. The outer shell is made of cold-rolled steel (Q235) with phosphating and anti-static powder coating. The working chamber is 3mm 304 stainless steel. The enclosure is reinforced to contain any internal explosion and prevent propagation to the outside.
Key safety features include:
For humidity chambers, we use encapsulated explosion-proof compressors and intrinsically safe sensors. The control system uses a 5.7-inch LCD with menu-driven interface and automatic screen lock to prevent accidental changes.
We provide standard models with defined temperature ranges and chamber sizes, but most projects require some level of customization. We can adjust the following based on your process:
We also integrate with automated production lines. Our control systems can include data logging, Ethernet or RS-485 communication, and alarm outputs for integration with your plant SCADA system. We ensure that communication interfaces do not compromise intrinsic safety.
Our factory operates under ISO-9001 with a 4-stage inspection process: incoming material, in-process, aging test, and final pre-shipment check. We use precision instruments to verify temperature uniformity and fluctuation. Each explosion-proof unit undergoes pressure resistance testing and leakage rate monitoring to confirm enclosure integrity.
We also perform thermal shock tests on the chamber structure to ensure joint tolerance stability. These tests are documented and included in the shipment. Our quality system is backed by 23 utility model patents covering heating systems, sealing structures, and energy-efficient designs.
