Note:
1. The cooling capacity is measured under the following temperature conditions: the coolant is alcohol; the cooling water inlet/outlet temperature is 32/37 °C.
2. Working range: The cooling water outlet temperature is 22 ° C to 37 ° C. The cooling water inlet temperature difference is 3.5 ° C to 10 ° C.
The outlet temperature of the freezing liquid is -55 ° C to -110 ° C. The temperature difference between the inlet and outlet of the freezing liquid is 2.5 ° C to 5 ° C.
3. The stainless steel wire connection of the pair of frozen liquid inlet and outlet is provided at the time of shipment, and the coolant (alcohol) is provided by the user.
4. The above specifications are subject to change without prior notice. This will help our company to bring the latest scientific and technological achievements to customers at any time.
 
        The company has independent intellectual property rights, multi-component mixed-use environmentally-friendly refrigerant, international advanced natural cascade refrigeration technology, research and development, design, production, sales of single-compressor ultra-low temperature cascade refrigerator (-80 ° C ~ 160 ° C) to achieve a number of Technological breakthroughs have gradually replaced traditional multi-compressor cascade chiller systems and liquid nitrogen refrigeration methods, and have been applied to various industries.
 
        One-time compression multiple natural segregation mixing medium self-cascading freezer refrigeration technology uses a single compressor, with multiple mixed working fluids as refrigerant, achieving low-temperature cooling of -160 ° C, beyond the traditional cascade refrigerator Cooling effect with two or three compressors. It greatly simplifies the structure of the refrigeration system, reduces initial investment costs, reduces system operation energy consumption, and improves system reliability. The self-cascading refrigeration unit refrigeration system uses the method of rectification to ingeniously complete the high-efficiency separation of lubricating oil and mixed working fluid, ensuring that the system does not have oil plugging problem in the low temperature section. The structure is simple, the operation is stable, the energy efficiency is high, the miniaturization is convenient, and a plurality of innovative technologies are possessed.
 
        The self-cascading freezer is compared to a conventional three-stage cascade freezer. In the same way to achieve low temperature refrigeration of -100 ° C, the technology reduces two compressors and two plate heat exchangers than the three-stage cascade cycle, and only adds one self-made liquid separator, regenerator, and as a mixer. The quality replaces the multi-stage refrigerant of the existing cascade refrigeration unit, which greatly reduces the cost, energy saving and energy consumption, and has a simple system structure and stable operation.
 
Self-folding three large pieces
        The natural cascade refrigerator mainly consists of a mixed working medium, a regenerator and an oil separator. It can be assembled into a self-cascading ultra-low temperature refrigeration system with a standard universal refrigeration unit such as a single compressor and a condenser to achieve a minimum of -160 ° C. Ultra-low temperature refrigeration and freezing function. It should be widely used in various cryogenic refrigeration equipments, such as high energy efficiency, ultra-low temperature, simple and reliable system, including ultra-low temperature freezer process, high and low temperature test chamber, ultra-low temperature refrigerator, low temperature thermostat, freeze dryer, ultra-low temperature cold trap and other industries. .
 
Self-cascading freezer
        The self-cascading freezer consists of a compressor, a set of self-assembling three large parts, a condenser plus fan, an oil separator, and some auxiliary accessories. Available in -60 °C, -80 °C, -120 °C, -150 °C, -165 °C temperature specifications. Compared with the traditional multi-stage cascade refrigeration, it has the advantages of simple structure, low installation cost, high temperature control precision, high efficiency and energy saving. Can be widely used in high and low temperature test chambers, low temperature thermostats, low temperature refrigerators, freeze dryers, low temperature cold heading, low temperature reactor, low temperature cold storage, natural gas liquefaction, BOG reliquefaction, ultra low temperature mobile phone opener, environmental waste gas recycling, various types Food freezing, aerospace and other fields.
 
Ultra-low temperature freezer
        Mainly used in pharmaceuticals: synthesis, hydrolysis, esterification, etherification and other processes that require temperature control; chemical industry: rectification and purification, rubber pulverization, low temperature grinding; metal treatment: low temperature assembly, low temperature fire; food: ultra-low temperature food processing such as tuna Storage; Electronics: environmental testing of components; aerospace: heat sink test, environmental simulation test of parts and components; environmental protection: waste gas condensation recovery, net emissions. Natural gas liquefaction, BOG reliquefaction; nuclear industry.
 
High and low temperature test chamber
        It is mainly used in the research and development of quality control engineering for the defense industry, aviation industry, automotive parts, electronic parts, plastics industry, food industry, pharmaceutical industry, and related products.
 
Cryogenic bath
        Mainly used in petroleum, chemical, electronic instrumentation, physics, chemistry, bioengineering, medical and health, life sciences, light industry food, physical property testing and chemical analysis, research departments, universities, enterprise quality inspection and production departments, working for users Provide a hot-cold controlled, uniform temperature field source for constant temperature testing or testing of test samples or products, or as a source of heat or cold for direct heating or cooling and auxiliary heating or cooling.
