Cold Head with Built in Liquefying Circuit
This option gives the customers the ability to create liquid helium for their external helium circuit. Only available with our 2 stage PT cold heads, this built in liquefying circuit liquefies Helium and directs the liquid through a VCR fitting. The helium gas enters the circuit through a fitting on the base plate. The helium is then precooled at the 1st stage heat exchanger then cooled again on the exterior of the 2nd stage regenerator tube. Lastly, the circuit directs the cooled helium to the 2nd stage heat exchanger where it condenses.
