Products & SolutionsDry Room

Dry room created by a dehumidifier manufacturer

As a manufacturer specializing in dehumidifiers—the core components of dry rooms—we have the expertise to meet a wide range of needs.


1. Dew point temperature available: As low as -90 °C DP

2. Equipped with a heat pump system and high energy efficiency

3. Optimal design according to conditions from equipment selection to installation

4. Includes a weekly scheduling function

Dry Room System Overview

Moisture in the air acts as an inhibiting substance in the manufacturing processes of lithium-ion secondary batteries and organic EL displays. Therefore, research, development, and production are conducted in dry rooms that maintain a low-humidity environment.

Dehumidifier supply air volume(m3/h)

Example : Dry room with a humidity load of 100 g/h
