Selecting Liquid Cryogenic or Cryogen-Free Cooling

Cryostats are available as pour-filled liquid cryogen dewars or cryogen-free refrigerators. In general terms, dewars are passive cooling devices that contain vacuum-insulated reservoirs of LN2, LHe, or LN2 plus LHe that provide all cooling power needed in these open cycle systems. Refrigerators use mechanically refrigerated cold heads embedded in a vacuum case in a closed cycle system. Both dewar and refrigerator systems are readily adapted to many different applications.

Cryostats

Liquid Cryogenic Dewars

Liquid cryogen dewars are compact with no moving parts, easy to use, and have a lower initial cost. Recommended for simple, reliable operation:

  • Use LN2 and LHe
  • Simple, compact cooling solution
  • Lower cost of equipment
  • No mechanical noise and vibration
  • No bulky compressor and hoses
  • High reliability

Hybrid System

Cryogen-Free Refrigerators

Refrigerated systems are larger, more complex, and have a higher initial cost but eliminate the expense of refilling cryogens. Recommended for cost-effective, continuous unattended cold operation:

  • Uses mechanical refrigeration
  • No expensive LHe
  • Continuous operation with no refilling required
  • Reliable; no unexpected warmups
  • Acceptably low vibration in most cases
