Excellent R&D strength and quality assurance

Rotary Dehumidifier Testing Center

 

Equipped with advanced sensors, our testing center continuously monitors key operating parameters to accurately assess the dehumidifier's performance and operating status. Real-time test data can be accessed anytime via mobile devices, offering valuable insights for fault diagnosis and condition evaluation-driving smarter maintenance and continuous product optimization.

 

Chiller Performance Testing Center

 

The testing center is equipped to evaluate both water chillers and water/ground source heat pumps, simulating year-round operating conditions. It supports single-unit testing up to 1200 kW, ensuring reliable performance validation under real-world scenarios.

 

100HP Environmental Simulation Laboratory

 

This state-of-the-art laboratory is equipped to test chillers & heaters, direct expansion units, combined air conditioning units, and fan coil units-with dedicated capabilities for explosion-proof equipment. It can simulate year-round operating conditions and supports single-unit testing up to 300 kW, ensuring comprehensive and reliable performance validation.

 

Environmental Simulation Enthalpy Difference Laboratory

 

This laboratory can simulate extreme environments with temperatures ranging from -30°C to 50°C. It tests dehumidifier performance under various climate conditions, while real-time monitoring of operating parameters is conducted through a central control room. This ensures a solid foundation for the stable and reliable operation of dehumidifiers.

Sujing is a large - scale manufacturer specializing in heat pumps, chillers, dehumidifiers,AHUs,etc.. We excel at providing professional customized solutions, capable of handling both modular units and non - standard custom design and manufacturing.

Boasting a complete set of production lines, including those for heat exchangers,sheet metals, filters, panels, heat pumps, chillers, AHUs and dehumidifiers, we can independently accomplish the entire production process from components to finished products.

With factories in Suzhou, Yancheng and other cities, a branch in Germany, an office in Indonesia, as well as multiple service centers worldwide, we offer comprehensive and thoughtful services. Our equipment has been exported to the United States, Canada, Hungary, Turkey, South Korea, India and many other countries, backed by rich experience.

Product Description

Rotary dehumidifiers work by drawing moist air through a rotating desiccant wheel. The desiccant material (typically silica gel or molecular sieve) adsorbs moisture from the air. As the wheel rotates, the saturated section moves to a regeneration zone, where hot air drives off the absorbed moisture, allowing the desiccant to reuse. This cycle ensures continuous dehumidification.

They are ideal for scenarios requiring precise humidity control, such as electronics workshops, pharmaceutical factories, food processing facilities, museums, and storage warehouses for moisture - sensitive goods.

Sujing's rotary dehumidifiers boast the following key advantages:

• High Efficiency: Equipped with high-performance desiccant wheels, ensuring strong moisture absorption to meet diverse needs.

• Energy Saving:Backed by a strong R&D team and years of deep engagement in the field, Sujing's dehumidifiers feature more rational designs. Compared with other dehumidifiers on the market, they are more energy-efficient and cost-saving.

• Customization:Sujing's technical team responds quickly and can provide professional customized solutions. We offer flexible adjustment of dehumidification effects and efficiency, with models (e.g., -60ºC low dew point, compact unit,easy-to-installation machine,etc..) tailored to various scenarios.
