About us
Dryvex designs and builds industrial dehumidifiers, desiccant rotor units, ultrasonic humidifiers and constant temperature and humidity equipment, supplied to factories, cold chain, pharmaceutical, food and building projects.

Dryvex designs and builds humidity control equipment: condensing dehumidifiers for workshops and stores, ceiling and ducted platforms for concealed installation, desiccant rotors for low dew points, ultrasonic humidifiers for dry processes, and constant temperature and humidity units for rooms that must hold both values.
The factory covers 7,200 m² in Hangzhou, Zhejiang, and works across application, design, engineering, manufacturing and assembly. Cabinets are built to a released drawing, coils and rotors are fitted against the agreed supply, and each unit is run before dispatch so the drawing set delivered with the equipment matches the tested configuration.
Equipment has been supplied to underground car parks, pharmaceutical plants, cold stores, ice rinks, laboratories, food factories, printing halls, pools and residential projects. The approach is the same in each case: start from the room, state the assumption, and put the calculation behind the recommendation.
