Vacuum insulation for high temperature fluid transfer up to 815C (1500F)

Insulating high temperature fluid systems has never been simple. After installing the process piping, a secondary insulation material needs to be wrapped around the pipe and clamped, taped, or otherwise fixed into place. Once installed, the insulation requires periodic inspection and maintenance to manage moisture, corrosion, and other issues.

Now, high temperature insulated tubing is available in the form of Insulon Vacuum Jacketed Hose for fluid transfer systems up to 815 Celsius (1500 Fahrenheit). A groundbreaking solution for high temperature applications, Insulon hose delivers ultra-high performance thermal insulation in a corrosion-resistant, stainless steel package.

The vacuum barrier is pre-installed into the double-walled hose, arriving at your facility with the thermal insulation already in place. Rather than installing transfer hoses and insulation materials separately, the pre-insulated Insulon hose can be installed in one easy step.
