Select the right performance level for your application
With Insulon hose, customers can build the vacuum jacketed hose system that is right for their unique application, goals, and constraints. Liquid cryogens rely on special features like multi-layer insulation (MLI) to minimize boil-off losses. Manufacturing plants that require hoses to consume as little space as possible select Standard hoses to reduce the outer diameter. Applications that need an easy-to-maneuver insulated hose, including cryogenic dispensing, benefit from improved handling and ergonomics with Standard Insulon hoses as well.

Standard Performance
With a smaller outer diameter, Standard Insulon Hose are ideal for space-constrained systems or applications that require greater degrees of flexibility.
- Proprietary Insulon vacuum space
- Smaller outer diameter
- Greater flexibility (smaller minimum bend radius)
- Excellent thermal insulation performance
- Reduce boil-off material losses
MLI Performance
With proprietary, high-density multi-layer insulation, Insulon Hose with MLI deliver maximum thermal insulation for cryogenic fluids to minimize boil-off material losses.
- Proprietary Insulon vacuum space
- Larger outer diameter
- Less flexibility (larger minimum bend radius)
- Maximum thermal insulation performance
- Minimize boil-off material losses
Reduce condensation in cryogenic dispensing applications
Cryogenic dispensing applications often opt for uninsulated hoses due to their lightweight and flexible design. But, this leads to excessive moisture buildup and dangerous exposure to extreme temperatures. With Standard Insulon Hose, cryogenic dispensing applications finally have low profile, flexible, vacuum insulated hoses to improve operator comfort and safety.

Safer surface temperature analysis
This chart illustrates the temperature difference between the process media (LN2, -196°C) and the external surface of an Insulon vacuum jacketed hose. The temperature difference at steady state was over 205°C (369°F). Ambient temperature was 23°C.
This analysis was conducted with a 1/2″ ID x 6′ L Insulon Vacuum Jacketed Hose, Low Pressure, Standard. High pressure hoses also available. Option to include multi-layer insulation (MLI) for “super” insulation performance.
Reduce boil-off losses up to 45% compared to other vacuum jacketed hoses with MLI
High performance Insulon Vacuum Jacketed Hose includes multi-layer insulation (MLI) to reduce boil-off material losses by up to 45%.
- During the LN2 Boil-Off Testing, Insulon Vaucum Jacketed Hose with MLI achieved a boil-off rate of 0.6 W/m.
- During the same period, another vacuum jacketed hose with MLI allowed liquid nitrogen to boil-off at a rate of 1.1 W/m.
Insulon hoses are engineered for cryogenic fluids including liquid nitrogen, hydrogen, helium, oxygen, and more. In addition to minimizing boil-off, Insulon Vacuum Jacketed Hoses with MLI reduce condensation, improve thermal energy efficiency, maintain safer surface temperatures, and more.
Ideal for space-constrained applications, Insulon hoses have smaller outer diameters than most other vacuum jacketed hoses. (Learn more → How compact are Insulon vacuum jacketed hoses?)
