Nichias Product Features
High Air Volume Capacity
Thanks to the honeycomb structure, pressure loss (airflow resistance) is low, enabling dehumidification of large air volumes while reducing fan power consumption.
Effective Dehumidification Even at Low Temperatures
Compared to compressor-based systems, stable dehumidification performance is maintained even in low-temperature environments without any degradation.
Easy Maintenance
The rotor rotation mechanism has a simple structure, making maintenance straightforward and hassle-free.
Long Service Life
All materials used offer excellent heat and moisture resistance, resulting in an extended service life.

Overview
In recent years, moisture in the air has become a major cause of quality issues across a wide range of industries, including pharmaceuticals, food processing, chemicals, semiconductors, and lithium-ion batteries, making humidity control an absolute necessity.
Dehumidification methods for controlling and managing humidity include the desiccant dehumidification method, which uses dehumidifying materials, and cooling dehumidification, which lowers humidity through supercooling.
Nichias has long supplied the market with honeycomb rotors for desiccant dehumidification (hereinafter referred to as "dehumidification honeycomb rotors").
Structure
The dehumidification honeycomb rotor is a product in which a highly active hygroscopic material is impregnated into a honeycomb structure, reinforced with a metal frame, and formed into a rotor shape. When installed in a dehumidifier, it provides dehumidification functionality.
Operating Principle
The dehumidification honeycomb rotor is used in a device divided into zones by a heat-resistant seal structure: (A) Process Zone + Regeneration Zone, or (B) Process Zone + Cooling Zone + Regeneration Zone.
By rotating the rotor at an optimal speed determined by air conditions, dehumidification (adsorption) and regeneration (desorption) are carried out continuously, enabling a steady supply of dry air.
