Damper lined with high-temperature insulation

Vacuduct is Danser, Inc.’s patented high-temperature vacuum-formed ceramic fiber insulation. Below we dissect what it is, as well as its properties and applications.

What is high-temperature insulation?

High-temperature insulation is used for applications operating at 650⁰F or higher. Typical applications include: expansion joints, heat exchangers, furnaces, ovens and kilns, dryers, exhaust duct, exhaust stacks, combustors, afterburners, and more.

What is high-temperature ceramic fiber insulation?

High-temperature insulation can be broken into several categories, one of which is ceramic fiber. This type of insulation uses high-temperature ceramic fibers made from alumina-silica materials. Ceramic fiber insulation is stable in high temperatures and has low heat storage and excellent thermal shock resistance.

What is high-temperature vacuum-formed ceramic fiber insulation?

Vacuum-forming is the process of using a vacuum system to draw a ceramic fiber water solution through a product-shaped filter die. As the water is drawn out, the ceramic fiber is deposited on the die. The die is removed before the ceramic fiber component is dried in an oven. This process allows for versatility of size and shape to best meet customers’ needs. Danser’s patented process for high-temperature vacuum-formed ceramic fiber is Vacuduct.
