Setting up a new liquidfier

A project log for Helium Recovery Recycling System

I manage a helium recovery system. Labs use liquid helium for their experiments and I recover that helium as gas and liquidfy it.

Finished installation of the liquidfier unit.

This is our bigger liquidfier. I installed this over a few months. We had to run braided stainless steel helium lines to the pulse tubes to the external compressors. The units are from CryoMech. It has a 500L dewar and it can liquidfy 60L a day.

Installing stainless lines. Very fragile and easily damaged. It took a few guys to run each line and they did not like to be bent in certain ways. It was very stiff

More photos of the compressors. They use pulse tube refrigerators. The compressors are similar to a hvac style compressor. It has a Hitachi Scroll compressor unit inside modified for helium use. Each stainless steel line is pressurized to 200 PSI and it uses helium as a refrigerant.

I had to move the liquidfier away first to set up the lines. We had a overhead crane at our facility to lift it in place.

Finished product. Sadly the computer that was sent to use died and our RMA package was actually lost when we shipped it back to the company. Our temporarily permanent computer in place of the official unit.
