Industrial Dehumidifiers — Manufacturer of Commercial and Industrial Dehumidification Equipment

Our dehumidifiers use R290, R134a, or R32 depending on the model and capacity. Smaller commercial units (GDH-50E, GDH-58E) use R290 or R134a; mid-range and industrial models (GDH-60E and above) typically use R290; some industrial models also support R32. The exact refrigerant for each model is listed on its product page. For OEM projects, we can adjust the refrigerant choice to match destination market regulations (for example, R290 or R32 for EU markets to meet F-gas requirements).

Compressor dehumidifiers (GDH and GDH-CE series) operate efficiently between 5°C and 38°C. For environments below 5°C — including cold storage, pharmaceutical low-temperature warehousing, and electronics drying rooms — or for applications requiring relative humidity below 30%, the ROD rotary desiccant series is the appropriate choice. ROD units use a desiccant rotor with PTC regeneration heating, so they don't rely on condensation and maintain extraction performance at low temperatures. Catalog applications include defense, aerospace, electronics manufacturing, chemical industry, pharmaceutical storage, cold storage, textile, artwork drying, and specialized drying rooms.

Compressor dehumidifiers in our catalog operate between 5°C and 38°C (some models 5–35°C or 5–30°C — check the specific product page) at 30%–80% relative humidity. Rotary desiccant ROD units extend operation to lower temperatures and lower target humidity. Each product page lists the verified working temperature and humidity range for that model.

Compressor dehumidifiers ship with LCD touchscreen control and built-in humidity sensors that allow operators to set a target humidity level. Rotary desiccant ROD models offer adjustable humidity differential between 1% and 5%, allowing tighter control for applications such as pharmaceutical storage and electronics manufacturing where ambient humidity must remain within a narrow band.

Yes. Smaller commercial units (GDH-50E to GDH-138E) include a water tank with optional drain hose. Industrial floor-standing models (GDH-180E and above) and ceiling-mounted GDH-CE models use direct continuous drainage through a drain hose, suitable for unattended 24-hour operation. Drainage method for each model is listed on its product page.

Both the condenser and the evaporator in our dehumidifiers use copper tubing. Copper provides higher thermal conductivity than aluminum and better resistance to corrosion under continuous high-humidity operation. The GDH-CE ceiling-mounted series additionally uses titanium foil for the fin material, which helps in chemically aggressive environments such as indoor pools.

Standard protections across the range include automatic defrosting (prevents ice buildup on the evaporator) and fault self-protection circuitry. The ROD rotary desiccant series adds rotor rotation-stop protection (prevents rotor damage if rotation fails) and electrical leakage protection. Specific protections for each model are shown in its product specification.

Yes. Our catalog publishes a 6-step customization process: (1) requirement analysis — including review of customer construction drawings if available; (2) solution and model selection; (3) specification confirmation before production; (4) production and in-house assembly; (5) functional testing and 100% final inspection; (6) export-standard crate packaging and shipping. We can adjust specifications such as voltage, refrigerant, dimensions, branding, and packaging.
