Instructions to Use Explosion Proof Refrigerator

Explosion Proof Refrigerator is a kind of special refrigerator mainly used for the special industrial environment to keep dangerous goods which are difficult to preserve, volatile and inflammable and explosive. With the development of petroleum, chemical industry, medicine, aerospace, military and other fields, the use of explosion-proof refrigerators is more and more frequent. However, in terms of technology, performance, technology, design and so on, few can meet the national standard.

As to the use of the refrigerator for the first time, you must follow the instructions, otherwise, improper operation may cause some unnecessary accidents. So you should carry out in accordance with the corresponding instructions to the operation and avoid freely use the machine with high precision, in order to avoid the loss of function of the equipment, which will cause more dangerous results.

Also, it should be noted that you can run it for one to six hours with an empty container when electrifying for the first time, so as to make sure the equipment is at a normal state, after which you can put the objects in it. Meanwhile, If the machine stops when running, you should wait at least five more minutes before it can be turned on again, so as not to damage the compressor in a short time. These small details noticed the use of such high-precision instruments will be easier.
