Chemistry and Chemical Explosion refrigerator cold storage belonging to one of the design requirements of the standard in general is higher than the average refrigerator, Mainly used for some chemical industrial supplies, chemical reagents, laboratory research. As a result of explosion-proof refrigerator versatile leading microelectronics technology integration and optimization of proof; and the use of all-optical isolation microwatt level intrinsically safe control circuit, multiple security technologies, standardization of technology and technology leading import compressor, refrigeration equipment cold storage explosion and accessories must be explosion-proof rating, for example, explosion-proof switch, explosion-proof pipeline, explosion refrigeration compressors, chillers, etc. explosion. Cold storage design and installation of explosion-proof characteristic aspects of the analysis in several ways: (1) Explosion-proof integrated cold storage using leading technology, the size and weight-proof system only uses a few tenths of a traditional proof technology. Its microwatt level full optical isolation intrinsically safe control safety circuits, several orders of magnitude than the use of traditional techniques, and low system price. (2) proof sets cold by a separate unit composed of explosion-proof cooling system, a leading international technology imported compressor and direct cooling mode, and therefore reliable, maintainability, including valves, pipes selection and installation; ( 3) proof refrigerator using pressure and temperature monitoring of multiple protection technologies limit the maximum surface temperature: when abnormal conditions and airtight leak-proof structure can shutdown protection. While using anti-ignition ground and other security technology, good safety performance. Users also optional upper and lower temperature alarm device. (4) The user can demand the flexibility to choose the volume, the number of units and the installation of auxiliary equipment, applicability, ease of disassembly, moving, expansion and so on. Other cold-related work. During the construction process, we must strictly regulate the project mainly by the building envelope, refrigeration units, library evaporator, cooling piping, temperature control system and defrost drainage systems and other components. People ran to the explosion process refrigeration proof cold storage design, material selection, each system equipment installation, commissioning, maintenance and repair services; construction of electrical control systems and lighting systems of cold storage, always strict quality control. During operation, sealed good, manipulation of light, save energy. All cold storage are in accordance with customer requirements and design of professional programs, to ensure that we do every cold storage can provide users with the largest savings and most convenient to use.
