Deep Freezer

Units cryogenic refrigeration system consists of high-temperature parts and low temperature part. Their low temperature portion to provide the required cryogenic capacity, high temperature RR404A, low temperature cryogenic refrigerant R23, etc., but the type of the refrigerant condensing temperature low requirements with cooling water under the same pressure is difficult to its condensation. The high temperature portion of the refrigerant circulating in use temperature, and its role is used for the condensation temperature refrigerant, the high temperature portion and a low temperature portion sharing an evaporator condenser and "cascade", thereby forming a cascade refrigeration cycle to apply two refrigerants.

A. dual cascade cryogenic machine:

Dual cascade refrigeration system combination temperature stage (R404A/R22), low temperature R23, ultra-low temperature -30 ? - 80 ? process cold source; frozen mechanism cold quantity range dual cascade 5kw ~~ 700kw; the dual cascade cryogenic freezer at home and abroad have strong economic and technological advantages.

B. three yuan cascade cryogenic machine:

By the temperature stage (R404A/R22) cryogenic stage R23, ultra-low temperature level (R14) combination, the the lowest -120 ? ultra-low temperature process cold source. Dual cascade frozen mechanism cold quantity range 3kw ~ 300kw;

C. The stand-alone automatic cascade cryogenic unit, using a variety of non-azeotropic working fluid, single-stage compression, automatic cascade, -40 ° C to -135 ? cryogenic liquid, due to the stand-alone compression technology automatically cascade The system is simple, with high reliability, cost-effective and high.

1 Germany Bitzer compressor Taiwan Hanbell semi-hermetic twin-screw compressor; major components are internationally renowned imported brand components, such as Denmark, Danfoss, Emerson, Alco, USA, Italy Castel refrigeration components; energy efficient, stable;

3 Germany Siemens Siemens industrial grade PLC programmable controller and a large-screen man-machine interface of touch screen LCD; self-control of a high degree, the operation is simple and convenient.

4 special scientific oil subsystem design to solve the traditional cascade low temperature units the cryogenic refrigeration oil is difficult to separate technical problems, so the device can achieve continuous production

5 special pressure relief the expansion system design; scientific the cryogenic equipment refrigerant R23 can ensure at any time in the including safety pressure range, more security, more energy-efficient, environmentally friendly;

 (5, 6, is characterized by the company in the years to cascade unit design optimization results; reached the international advanced level).

6. Electronic expansion valve refrigerant trace precisely regulated to ensure that the unit part load and full load can be energy-efficient to run. Incorporated in the compressor itself with the energy adjust steplessly energy regulation basis, can be transferred with a dedicated hot gas bypass, can achieve 10% -100% of the units.
