Below a schematic overview of the basic components of our cryogen-free dilution refrigerator system. On the left the control unit,  in the middle the gas handling unit, and on the right the dilution refrigerator unit.

The control unit contains all electronics, pump controllers, pressure and flow readout equipment and pneumatics to control the valves. It connects to the gas handling unit by pneumatic lines and a few electric control lines. All pumps and compressors in the gas handling unit are oil-free and require little maintenance. Like anywhere else in our system, we only use high quality products, for example pumps from Varian, vacuum valves from VAT and pressure sensors from Pfeiffer Vacuum. The gas handling unit should preferably be placed in a separate pumping room. Finally this unit connects to the dilution refrigerator unit , which also contains the Cryomech pulse tube cooler. 

 All connections between the different units will be delivered to customer's length specifications.
