Low temperature technique – cryogenics

Cryogenics deals with studying and using material properties in low temperatures. It is also used to obtain and measure low temperatures. Cryogenics makes a substantial contribution to the fields like: cosmic space research, biology and medicine, industries: food, metallurgy, chemical and superconductor devices.

We specialize in practical cryogenics use.

We handle design and production of devices for keeping low temperatures (cryostats) and cryogenic lines for liquid oxygen and nitrogen transfer.

We are experts in selection of elements for transfer lines of liqufied gases and heat isolations:

  • vacuum isolation (heat transfer ratio k=5 mW/mK)
  • multi-layered isolation (heat transfer ratio k=0.01 mW/mK)
  • powder isolation (heat transfer ratio from k=0.01 mW/mK  to k=44 mW/mK, depending on customer requirements)

Our experience applies the use of:

  • the phenomenon of boiling cryogenic liquid eq. liquid nitrogen (-195.8°C) or liquid synthetic air (-191°C)
  • systems using Joule ’a-Thompson’s phenomena using carbon dioxide (-57°C) or nitrous oxide (-87°C)
  • freon refrigeration systems
    • cascade systems – much more efficient then multistage systems by having independent cooling systems, refrigerants and compressors (minimized problem of oil leveling)
    • auto-cascade systems – used to achieve a temperature range of -70°C to -110°C, using compact design but relatively low cooling efficiency to achieve ultra-low temperatures.

Low temperature systems are designed for individual customers and designed to meet very specific requirements.

Based on our knowledge and experience we are able to offer a solution that will meet your expectations.
