  • Insulation coating does not interfere with the rotation of the drying cans
  • Long lasting performance (5-10 years or more)

When a denim manufacturing company contacted energy efficiency expert, Kolorgen Ltd., they had an interesting challenge. They’d never been able to insulate their rotating drying cans to save energy. This was due to the limited amount of space and the constant rotation during the manufacturing process.

Fiberglass, mineral wool, foam… nothing they found was suitable. That is, until Kolorgen introduced them to Synavax™ patented thin film thermal insulation technology.

Their steam temperature was 160C (320F) and they were losing a lot of heat energy! The denim factory used Heat Shield™ High Heat thermal insulation coating by Synavax™ in an easy spray-on application on the ends of the cans that did not interfere with the rotation of the drying can array.

They were thrilled with the savings and grateful to have finally found a solution for energy savings on this equipment.

Bold Plans. Bold Results.
