Description
   The CS-202FF is a versatile closed cycle cooler with an o-ring sealing surface for easy integration. The system typically includes a compressor, hoses, DE-202FF expander, temperature controller and sensor and heater instrumentation.  The DE-202NFF is a modified version of the two stage Gifford-McMahon refrigerator.  This inexpensive modification results in a 6.5 K bottom out temperature and higher capacity at 10 K.

Features Include:
  • 10 K to 350 K operation
    or 6.5 K to 350 K and
    (Options 450K and 800K)
  • 36W, 36V foil resistance heater
  • Higher Capacity at 10 K for the 202N
  • Simple pneumatic drive has only two moving parts allowing easy field maintenance
  • Hermetic compressor component is designed specifically for helium operation for maximum reliability
