Desiccant & Zeolite Rotors — industry application reference image

The Substrate Inside Every Honeycomb Rotor

Desiccant and zeolite rotors are built from flat and corrugated paper layers wound into a honeycomb, then loaded with silica gel, molecular sieve or zeolite. Our wet-laid glass fiber forming paper is the substrate rotor manufacturers corrugate, wind and impregnate into their own wheels.

01

The Industry Challenge

The rotor substrate has to survive corrugating and winding without cracking, accept the impregnation or coating chemistry, and stay stable through repeated adsorption and hot regeneration cycles. Because every rotor maker uses its own channel geometry, adsorbent and process, the paper has to be matched to that process rather than chosen from a generic data sheet.

Typical Components

  • Silica gel desiccant rotors for industrial dehumidification
  • Dehumidification rotors for battery dry rooms and pharmaceutical production
  • Zeolite rotor concentrators for VOC abatement
  • Molecular sieve rotors for low-dew-point drying

Key Benefits

01

Inorganic glass fiber base suited to hot regeneration air; limits depend on binder and the finished rotor

02

Wet-laid formation for an even fiber distribution across the roll

03

Roll material sized for corrugating and winding lines

04

Basis weight, thickness and width reviewed against your rotor design

05

Binder selected for compatibility with your impregnation or coating system

06

Sample trials through your own process before production approval

04

What to Confirm When Selecting

Fiber performance depends on the finished part and process. Confirm these conditions with our engineers before choosing a grade.

01

Rotor type and adsorbent: silica gel, molecular sieve or zeolite

02

Channel geometry and the corrugating or forming method

03

Impregnation, coating or in-situ synthesis route and its chemistry

04

Regeneration temperature and operating environment

05

Validation method and acceptance criteria for approval
