HL Cryogenics stands out worldwide for designing and building top-tier cryogenic equipment. We help people handle liquid nitrogen, liquid oxygen, LNG, and other super-cold fluids in all sorts of industries — from labs and hospitals to semiconductor factories, space projects, and LNG terminals. Our main products, like Vacuum Insulated Pipe, Vacuum Insulated Flexible Hose, Dynamic Vacuum Pump System, Insulated Valves, and Phase Separators, form the backbone of safe, reliable cryogenic transfer and storage systems. Take our recent work in lunar research as an example. Our Vacuum Insulated Flexible Hose proved itself under brutal conditions on a lunar project, showing just how tough and dependable our gear really is.
Let’s talk a bit about what makes our Vacuum Insulated Flexible Hose tick. The design uses advanced vacuum insulation, plus layers of reflective shielding, to keep heat out and cold in. Inside, you’ve got a corrugated stainless-steel tube that’s both flexible and tough enough to work with LN2, LOX, LNG—basically any cryogenic fluid you need. The outer vacuum jacket, also stainless steel, protects that vacuum layer and shrugs off bumps and knocks. We custom-engineer the ends—bayonet, flanged, whatever the job calls for—so everything fits tight and leak-free into your system. Thanks to that multilayer insulation, you can move liquid nitrogen over long distances without losing the chill, keeping experiments on track where temperature really matters.
Our Vacuum Insulated Pipe works hand-in-hand with the Vacuum Insulated Flexible Hose, giving you a rigid option for moving cryogenic fluids over distance. These pipes use seamless stainless-steel inner tubes and the same vacuum-jacketed, multilayer insulation approach. The result? Outstanding thermal performance in everything from nitrogen labs to LNG plants. Our Insulated Valves and Phase Separators round out the system, letting you safely shut off flow, fine-tune regulation, and separate gas and liquid phases—all while keeping things cold and stable. We build all these components to tough standards—ASME, ISO, or whatever the customer needs—so engineers know they can count on our stuff.
The Dynamic Vacuum Pump System is a crucial part of the package. It keeps the vacuum insulation in top shape by actively maintaining low pressure inside the Vacuum Insulated Pipes and Vacuum Insulated Flexible Hoses. That means you get maximum insulation for the long haul, even if conditions change or you’re not running the system all the time. This matters a lot for space projects, where gear absolutely has to work—no excuses. We keep downtime to a minimum with regular monitoring and maintenance, stretching the life of your equipment and keeping costs down for labs, hospitals, and industry.
We’ve seen it firsthand—our Vacuum Insulated Flexible Hoses keep their flexibility and reliability through endless cycles of freezing and thawing. The combo of high-grade steel, vacuum insulation, and reflective barriers lets these hoses handle bending and mechanical stress without losing vacuum or letting heat sneak in. On lunar analog missions, they delivered liquid nitrogen exactly where it was needed, keeping sensitive materials cold and stable. Our Valves and Phase Separators managed the flow and phase changes smoothly, preventing pressure spikes and making sure everything stayed precise in tight, temperature-critical spaces.
At HL Cryogenics, safety and thermal efficiency drive our designs. Every piece we make—pipes, hoses, and all the supporting equipment—focuses on reducing risks like overpressure, frost buildup, or mechanical failure from temperature swings. The high-vacuum insulation slashes heat leak to almost nothing, and the extra shielding boosts performance for non-stop LN2 delivery. For LNG terminals or chip manufacturing plants, this means you lose less product, run more efficiently, and stay compliant with tough industry rules.
