Selecting the right performance level for high temp vacuum jacketed hoses

Share on:

For high temperature fluid transfer applications that require very high levels of insulation performance, Insulon Vacuum Jacketed Hose provides a compact, effective, and reliable solution. Insulon hoses are used to insulate high temperature fluids up to 900 degrees Celsius (1652 degrees Fahrenheit).

Critical high temperature fluid transfer applications include deposition lines in semiconductor manufacturing; steam lines in food production processes; and hot exhaust gases found in a range of industrial applications.

Insulon Vacuum Jacketed Hose are available in two performance levels: Standard and High Performance (MLI). Standard Insulon hoses are engineered to be compact, lightweight, and highly flexible. Insulon hoses with MLI are engineered with multi-layer insulation to deliver the maximum thermal insulation performance. Both performance levels include the following features:

  • Diameters: 1/4″, 3/8″, 1/2″, 3/4″, and 1″ ID
  • Lengths: 0.6 to 20 meters (2 to 66 feet)
  • Operating temperature: -270 to 900 C (-454 to 1652 F)
  • Material: 316L stainless steel
  • Pressure: High pressure and low pressure options
  • End fittings: Compatible with virtually any end fittings
  • Delivery: Quick lead times

Standard Insulon Vacuum Jacketed Hose

Standard Insulon vacuum jacketed hoses are engineered to deliver outstanding thermal insulation in a lightweight, compact, and flexible transfer line. Standard Insulon hoses use ultra-deep Insulon vacuum barriers to minimize convective and conductive heat transfer. Unique benefits include:

  • Sleekest, most compact design
  • Smaller outer diameter than most other vacuum jacketed hoses
  • Very flexible; Smaller minimum bend radius
  • Lightweight, ergonomic hoses ideal for mobile applications

The data above illustrates empirical test results. High temperature air was transferred through Insulon Vacuum Jacketed Hose, Standard, 1/2″ ID x 6′ Length. Inlet Media refers to the temperature of the air as it enters the hose. Midpoint External Surface refers to the touch temperature halfway along the length of the hose. Outlet Media refers to the temperature of the air as it exits the hose.

Insulon Vacuum Jacketed Hoses with MLI

Insulon hoses built with multi-layer insulation (MLI) are engineered for maximum thermal insulation performance. Insulon hoses with MLI use proprietary, high-density multi-layer insulation to minimize radiation heat transfer. While these hoses deliver the best thermal performance, they are slightly larger, heavier, and less flexible than standard Insulon hoses.
