​Explosion-proof refrigerators or explosion-proof freezers are mainly used in petroleum, chemical, pharmaceutical, scientific research, laboratory and other fields, used to cool and store pharmaceutical reagents at lower temperatures, and are not easy to store volatile flammable and explosive dangerous goods at room temperature. According to its structure, it is divided into single door, double door and multi-door and horizontal and vertical type. It consists of refrigeration compressor, condenser, condenser fan, evaporator, temperature controller. In order to make it safe to use in hazardous locations, we also use composite explosion-proof technology to protect the freezers. The compressor and condensing fan are treated by pouring or flameproof technology, and the thermostat is used as a passive switch and explosion-proof active optocoupler solid-state relay group to achieve a quality-safe temperature automatic control system. In order to protect the compressor from damage, time-delayed explosion-proof solid state relays and overload protection and thermal protection devices are adopted, and some control appliances are flameproof treatment. In order to prevent the harm caused by static electricity, spray conductive paint on the inner cavity of the freezer to eliminate the electrostatic effect, which is safer and more reliable to use; Set up closed inner tank, high safety factor; Forced air cooling, rotating fan for circulating cooling, special fuse protection, refrigerator designed with internal grounding protection
