Vacuum insulation for low temperature fluid transfer

Insulon hoses excel when handling extremely cold or cryogenic temperatures. The key lies in their double-walled design which offers unmatched thermal insulation and energy efficiency. By incorporating advanced vacuum technology, the double-walled hose creates a vacuum-sealed space between the inner and outer layers. The vacuum barrier effectively minimizes heat transfer and reduces cryogenic fluid boil-off losses.

Proprietary Technology

Insulon hoses are different from other vacuum jacketed hoses. They are manufactured with a proprietary process that has a range of benefits:

Low maintenance: Other vacuum jacketed hoses may require pump-down maintenance; Insulon hoses do not. Concept Group’s proprietary manufacturing process results in a hyper-deep vacuum space that delivers reliable, long term performance.

Smaller outer diameter: For a given inner diameter hose size, Insulon hoses typically have smaller outer diameters than other vacuum jacketed hoses. This makes Insulon hoses ideal for compact applications.

Compatible with hydrogen: Hydrogen is different from other cryogens and has its own unique material requirements. Insulon vacuum jacketed hoses are compatible with liquid and cryo-compressed hydrogen transfer.

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 (LP). High pressure hoses also available. Option to include multi-layer insulation (MLI) for “super” insulation performance.
