Technical Selection Reference for Industrial Dehumidification Systems

Correct sizing starts from the moisture load, not the floor area. The required extraction rate (L/day) is calculated from room volume, air exchange rate, target versus ambient relative humidity, operating temperature, and internal moisture sources such as open water surfaces, wet processes, or stored hygroscopic goods. The series overview below maps each SHISHUO product line to its design envelope. For project-specific load calculations, sizing support is available through our technical consultation channel.

Operating Envelopes by Series

• Standard compressor series (GDH floor-standing, GDH-CE ceiling-mounted): 5°C to 38°C intake air, 30%–80% RH working range, 180–1,440 L/day at 220V or 380V. All-copper condenser and evaporator in a moisture-treated sheet-metal housing, with continuous hose drainage as standard. Ceiling-mounted models connect directly to HVAC ductwork and keep the floor clear.

• High-temperature series: rated for intake air up to 60°C, using compressors and refrigerant circuits specified for elevated condensing temperatures. Intended for drying rooms, food processing, and heat-treatment plants.

• Low-temperature series: operates down to −3°C with automatic defrost, intended for cold storage and ice facilities. Below 5°C, or where the target is under 30% RH, desiccant technology is the correct choice; refer to the rotary desiccant dehumidifier range and the cold storage application page for configuration details.

• Swimming pool series: stainless steel cabinet with an e-coated copper condenser for chlorinated air, 380–1,440 L/day. Sizing follows pool surface evaporation load, as detailed in the indoor pool dehumidification page.

• Ducted fresh-air series: 30–156 L/day with continuous filtered outdoor air intake, for offices, basements, and facilities where humidity and indoor air quality are controlled together.

Control and Protection Specifications

Compressor models ship with LCD touchscreen control, digital humidity sensing, timer scheduling, and automatic defrost. Base electrical protection covers phase loss, overload, and compressor fault alarm. Rotary desiccant (ROD) models add rotor-rotation monitoring and leakage protection, with the humidity differential adjustable between 1% and 5% for process-critical rooms.

Engineering and Manufacturing Basis

Sheet-metal fabrication, heat-exchanger production, and final assembly are completed at the Jiaxing production base, which gives direct control over housing gauge, coil geometry, and brazing quality. OEM/ODM programs cover voltage and frequency adaptation (220V/380V/415V, 50/60Hz), refrigerant selection among R290, R134a, and R32, dimensional changes, and private labeling.
