Single Stage 30 K Class Cryocooler with Helium Compressor |
Quick View Leaflet
Single stage 30 K class cryocooler with Helium compressor are key component in various commercial and industrial applications. Single stage 30 Kelvin class cryocooler technology deploys Gifford McMahon cycle to achieve ultra-low temperature at it’s cold finger. These cryocoolers have unique role in applications with small heat load requirements for temperature range in-between boiling point of liquid Nitrogen 77 to 30 Kelvin. It is considered as dry and cryogen free technology to cool small equipment or samples while cutting down on the bulk of the traditional cooling infrastructure needed for the realization of this technology. Helium compressor module for operating this cryocooler is developed in house by modifying commercially available refrigeration compressors with suitable oil injection and separation sub-system for continuous supply of very high purity compressed helium gas.

2. Typical End Users
They are very popular amongst the low temperature scientific community because of their simplicity and high reliability. These systems are required in large numbers and has huge potential for producing liquid Nitrogen on demand in the field of animal husbandry for the livestock improvements program, Nuclear Magnetic Resonance (NMR), pharma industry, stem cell research and in-vitro fertilization (IVF). This can be deployed in several other applications pertaining to DAE, Defense, Public Sector, R&D Units, Universities, Large and Scale Industries. Cryocooler system inherently have very high reliability, thus provide continuous uninterrupted cooling for very long operating periods.
