Industry Cryogenic ULT Freezer

ULT Freezer Application:

It is mainly used in medical, industrial refrigerating treatment, so that the matrix of the metal structure to generate a uniform, fine and dispersed precipitation. The precipitation of carbide will improve the abrasion resistance, friction performance and increase hardness of metal. The carbide is the ideal alternative to liquid nitrogen.

For the copper sleeve and bearings contracting, it is widely used in precise mechanical assembly. Applied to large scale equipment (cars, large engineering machineries, aircraft component, Aerospace equipment parts, Military equipment parts etc.) lower temperature test. Can be used for touch screens, screen freezing unglued, demolition.

ULT Freezer Features:

  • Microcomputer control, cascade temperature controller, digital temperature display, 0.1°C regulation, operation temperature from -20°C up to -125 °C adjustable.
  • Multi-safety protection, more reliable operation.
  • Compressor from TECUMSEH, DANFOSS and EMERSON, automatic cascade refrigeration technology.
  • With self-diagnosis function, freezer overload protection, high pressure switches, overload relays, thermal protection device and other security functions, and fully guarantee the use of safety.
  • Three sealed mold layer of insulation, Extra-thick high-density polyurethane foam insulation layer, the effect of good insulation; Inline vacuum insulation panels.
  • Human design, more convenient and flexible.
  • Suitable for mechanical producing plant use.
  • Large condenser design, fully guaranteed plant environment cooling effect.
  • Wide volume ratio design, large load capacity design.
  • Can be set to open compressors and compressor off temperature.
  • Fault alarm (over-temperature alarm, sensor alarm, high alarm, overheat alarm compressor.
  • Delay boot protection.
  • So grounding components safely.
  • LED display, clear display inside temperature and the desire temperature; can set the over temperature alarm and the inside temperature, fault prompt functions.
  • Non-standard sizes can be customized, Ultra-low temperature freezer (can be produced within -100°C 100 cubic).
  • Power supply: 380V/50Hz, can be changed to other standard.
  • Optional: PLC controller, LCD color touch-screen, temperature recorder etc.
