Select your length and end fittings; lengths range from 2 to 66 feet (0.6 to 20 meters).

Cryogenic Applications

Minimize heat ingress, improve thermal efficiency, and reduce material costs with Insulon vacuum jacketed hoses with MLI for cryogenic fluids. High performance thermal insulation is critical for delivering high quality liquid cryogens with the lowest possible gas content. Reducing the amount of gas present in the transfer line help to minimize boil-off losses. Less boil-off means less wasted materials, helping conserving cryogens and reduce overall material costs. Including MLI in the vacuum space delivers the maximum thermal insulation performance available, and is particularly useful for applications where cryogens are flowing continuously. Compatible with liquid nitrogen, hydrogen, helium, oxygen, carbon dioxide, and other cryogens.

High Temperature Applications

Insulon vacuum jacketed hoses with MLI deliver the maximum thermal insulation for high temperature fluid transfer applications up to 900 degrees Celsius (1652 degrees Fahrenheit). At high temperatures, reducing radiation heat transfer becomes critical to effective thermal insulation. Minimize heat loss, improve thermal stability, and increase energy efficiency with Insulon Hose HP MLI, our highest performing, industrial-strength transfer line solution. Reduce the external surface of the transfer hose to limit extreme temperature exposure and improve safety. Compatible with process heating oils, steam, exhaust gases, carrier gases, and other high temperature fluids.
