At HL Cryogenics, we know that Molecular Beam Epitaxy (MBE) and semiconductor work leave no room for error when it comes to thermal management. That’s why we built our latest Vacuum Insulated Phase Separator—to raise the bar for liquid nitrogen delivery. Gas flash in complex cryogenic transfer setups can throw off temperature-sensitive processes, so using a top-tier Vacuum Insulated Phase Separator is key if you want pure, saturated liquid right where you need it. We focus on getting the most out of the latent heat in cryogens. Every Vacuum Insulated Pipe and cryogenic pipe we make fits into a system designed to keep energy loss as close to zero as possible. Our pipes rely on a tough multi-layer insulation (MLI) approach and high-vacuum tech, which seriously cuts down on heat sneaking in from the outside.

If you need some flexibility, our Vacuum Insulated Flexible Hose gives you the freedom to connect mobile Mini Tank units or tanker hookups to fixed lab gear—without losing vacuum performance. We don’t cut corners on quality. Each Vacuum Insulated Flexible Hose goes through helium leak testing, so you know the thermal barrier holds up, even after lots of heating and cooling cycles. The real backbone of any high-efficiency cryogenic network, though, is vacuum longevity. That’s why we introduced our Dynamic Vacuum Pump System. It keeps the vacuum jacket in top shape, making sure the Vacuum Insulated Valve and the rest of your cryogenic pipe network run at peak efficiency for years—decades, even.

With the Dynamic Vacuum Pump System, decision-makers can trust that their cryogenic hose and piping won’t slowly lose performance from outgassing, which usually plagues static vacuum setups. Safety and control matter, too. Our Vacuum Insulated Valve series tackles frost heave and stem seizing in both liquid nitrogen and liquid oxygen systems. It acts as a solid thermal break and lets you modulate flow precisely inside the Vacuum Insulated Pipe network, while still protecting sensitive actuators in the cold-box environment. For smaller labs or research setups, our Mini Tank line gives you compact, tough storage that works perfectly with our Vacuum Insulated Flexible Hose for quick, seamless deployment. Whether we’re helping out a massive LNG terminal or a high-stakes aerospace test site, we put reliability first—using advanced materials and sticking to strict international safety standards.

Our Vacuum Insulated Phase Separator uses gravity-feed and smart internal baffling to separate gas from liquid with almost 100% efficiency. That’s not just a nice-to-have; it’s crucial for stable MBE operations, where even tiny pressure swings can mess up thin-film growth. We build our cryogenic hoses and pipes with low-conductivity internal supports to cut down on solid conduction heat transfer. Maintenance is simpler, too, thanks to our modular design. This lets us offer custom cryogenic piping solutions that last and perform. From analyzing your liquefied gas distribution needs to installing the Dynamic Vacuum Pump System, we’ve got your back with technical support every step of the way.
