Working with liquefied gases like liquid nitrogen and liquid oxygen isn’t easy. You’re constantly fighting heat, trying to keep everything cold enough so your product doesn’t turn to gas and drift away. That’s where HL Cryogenics steps in. We build cryogenic piping systems with serious insulation—exactly what you need when every drop matters. Our main focus? Eliminating flash gas and keeping heat out. The star of our lineup is the Vacuum Insulated Phase Separator. It makes sure only pure, super-cold liquid actually reaches the end point, so you lose less along the way. Pair that with our Vacuum Insulated Pipe and Flexible Hose, and you get a transfer setup where thermal efficiency really drives the design. These pipes aren’t basic. They’re double-walled, with a high vacuum in between, plus layers of insulation to keep heat at bay.

If your setup needs lots of bends or tricky routing, our Flexible Hose handles that without letting the vacuum seal slip. Long-term performance matters, too. That’s where our Dynamic Vacuum Pump System comes in. It keeps the vacuum tight, fighting off any outgassing from the metal, so your system stays efficient for years—no surprises, no slow leaks in performance. And for flow control, our Vacuum Insulated Valve gives you precision without letting frost or ice build up outside. In a lot of LN₂ setups, the Phase Separator does the heavy lifting. It acts like the heart of the whole network, making sure gas and liquid get split so your application gets the best possible quality.
