How do Insulon hoses compare to other vacuum jacketed hoses?

Flexible insulon vacuum jacketed transfer hose in half inch diameter size

Insulon vacuum jacketed hoses deliver unparalleled thermal insulation performance in environments that require ultra-high precision and temperature control. Effective in both moderate and extreme conditions, Insulon vacuum jacketed hoses operate in applications ranging from -270 to 900 C / -454 to 1652 F.

Additional benefits include a compact design and small outer diameters, flexibility with low springback to reduce stress on joins and connections, and lots of options. Select from high pressure and low pressure hoses, with the option to include multi-layer insulation (MLI). Diameters include 1/4″, 3/8″, 1/2″, 3/4″, and 1″ ID. Lengths from 2 to 66 feet (0.6 to 20 meters).

Cryogenic vacuum insulation

Insulon hoses are engineered for cryogenic fluid transfer applications including liquid nitrogen, helium, and carbon dioxide. In addition, Insulon vacuum jacketed hoses for cryogenic hydrogen transfer are built with fully annealed materials to combat effects of hydrogen embrittlement.

High temperature vacuum insulation

Vacuum insulation is widely recognized as the most effective type of thermal insulation available, and is often compared to aerogel. This high performance insulation technology has supported the thermal demands of cryogenic (super cold) applications for many years. But, high temperature applications have had to turn to other materials.

Now, high temperature applications can also achieve ultra-high thermal insulation performance with Insulon technology.

Insulon is a proprietary, advanced form of vacuum insulation that uses hyper-deep vacuum spaces to deliver thermal insulation for cryogenic, cold, and high temperature applications.

Insulon vacuum jacketed hose delivers thermal insulation for fluid transfer applications from -270 to 815 degrees Celsius (-454 to 1500 degrees Fahrenheit).

Compact design; Smaller outer diameter

For a given inner diameter, Insulon vacuum jacketed hoses typically have a smaller outer diameter than other vacuum jacketed hoses. Insulon’s compact design is based on proprietary vacuum insulation and multi-layer insulation (MLI) technology.

Reducing the thickness of these insulated hoses helps make them lighter, more flexible, and more ergonomic. In addition to improving handling, Insulon’s compact packaging helps reduce both shipping costs and inventory storage needs. For space-constrained applications, Insulon hoses can fit more transfer lines in limited space.

To reduce size even more, Insulon customers can also choose to exclude multi-layer insulation (MLI). Insulon vacuum jacketed hose are available in low pressure (LP) and high pressure (HP) models without MLI for an ultra-thin design.

Multi-layer insulation

Option to include MLI

Insulon hoses with MLI are engineered with a proprietary, high-density form of multi-layer insulation for maximum thermal insulation performance, even in high temperature applications. MLI works by minimizing radiation heat transfer with layers of reflective materials.

Multi-layer insulation uses reflective materials to reduce radiation heat transfer

Option to exclude MLI

Insulon hose is based on proprietary vacuum technology that creates reliable, hyper-deep vacuum spaces to drastically reduce convection and conduction heat transfer. Many applications that transfer fluids intermittently, or that are at less extreme temperatures benefit from excluding MLI from the vacuum jacketed hose assembly. Benefits include an even smaller outer diameter for our most sleek and compact design, improved flexibility, and lighter weight.

No pump down maintenance

Insulon vacuum jacketed hoses are engineered with proprietary technology and do not need pump down maintenance. With traditional vacuum jacketed hoses, pump down maintenance can take hours. Reduce downtime and improve productivity with Insulon hoses.

Range of pressure rating options

Many insulated hose applications end up purchasing hoses with pressure ratings that far exceed their requirements. These overengineered products provide the adequate thermal insulation, but also incur unnecessary cost. Insulon vacuum jacketed hoses are available in a range of pressure rating options to best fit each application.
