The ST Series Refrigeration Air Dryer incorporates premium-grade compressors with multiple protection mechanisms. The patented WS Moisture Separator guarantees superior dew point performance. Featuring an 8-10°C temperature differential in the pre-cooler, which ensures minimal outlet relative humidity, while preventing orifice freezing, significantly outperforming comparable products. The pre-cooler recovers over 90% of cooling capacity, effectively reducing the evaporator's workload, resulting in total energy consumption of just 85% versus conventional models.

The HT Series refrigeration air dryer is engineered to handle inlet temperatures up to 80° C using eco-friendly HFC refrigerants R134a and R407C, featuring an energy-efficient design with oversized pre-cooler and counter-flow technology that deliver up to 25% energy savings, while its high-efficiency demister-type moisture separator has 99+% water removal efficieney to enable dew point performance - significantly superior to cyclone separators - with reliable operation guaranteed by heavy-duty hermetic refrigeration compressors for maintenance-free service, precise temperature control through an automated refrigeration system, and flexible power supply options for diverse installation requirements.

The HP Series high-pressure refrigeration air dryer features corrosion-resistant stainless steel plate heat exchangers and eco-friendly R134a/R407c refrigerants, delivering energy-efficient performance with its high-capacity cooling system that incorporates premium refrigerant compressors, oversized heat exchange surfaces, and an intelligently engineered cooling airflow design to ensure reliable high-temperature operation while maintaining stable pressure dew point.

The RSXB series blower-heated regenerative adsorption dryers utilize highly efficient, durable, and low-power-consumption blowers and heaters. These components thermally regenerate the adsorbent at high temperatures using ambient air, eliminating the need to consume finished dry air from the dryer system. The RSXB series is equipped with heat-resistant ball and butterfly valves featuring PPL seals and stainless steel internal components. All valves are rigorously tested to meet Risheng's strict quality standards. These dryers are designed to maintain a constant pressure dew point of -40°C (optional -70°C for enhanced performance).

The bottom of the adsorption tower is equipped with supporting ceramic balls, the airflow is evenly distributed, this can prevent the desiccant from being soaked, and the service life is longer, with the specially designed stainless steel diverter, the pressure loss can be greatly reduced. The high-performance desiccant, specifically designed for this system, achieves optimal dew points. The standard configuration of the whole series is high-performance pneumatic valve during operation, the reliability and pressure loss are obviously better than membrane valve and solenoid valve.
