Risheng offers six standard-color PD series models, with custom color options available to fulfill individual customer requirements.

ST Series Refrigerated Dryer

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.

HT Series High Temperature Refrigerated Air Dryer

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.

HP Series Refrigerated Air Dryer

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.

RSXB-ZP Series Zero Purge Blower Heated Desiccant Air Dryer

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).

RSXB Series Pure Loss Blower Heated Desiccant Air Dryer

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 of blast air heated regenerative adsorption dryers utilize heat-resistant ball and butterfly valves with PPL seals and stainless steel internal materials. All valves are tested according to Risheng's strict requirements. The RSXB series of blast heated regenerative adsorption dryers are designed for a constant pressure dew.

RSXY-ZP Series Zero Purge Heat of Compression Desiccant Air Dryer

The RSXY series compression heat regeneration adsorption dryer fully utilizes the heat generated by the compressor to thermally regenerate the adsorbent. This design makes it an energy-efficient adsorption dryer with remarkable energy-saving characteristics. It is specifically designed for use with oil-free lubricated air compressors, such as centrifugal air compressors, oil-free screw air compressors, and oil-free piston air compressors. The RSXY series is engineered to maintain a constant pressure dew point of -20°C, with an optional pressure dew point of -40°C for enhanced performance.

RSXW Series Heatless Desiccant Air Dryer

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.

RSXJ Series External Heated Desiccant Air Dryer

The bottom of the adsorption tower is equipped with supporting ceramic balls, ensuring even airflow distribution, 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 specially designed high performance desiccant can obtain the best dew point. The standard configuration of the whole series is high-performance pneumatic valve, offering superior reliability and significantly lower pressure loss compared to membrane valves and solenoid valves during operation.

Rear Cooler

Risheng Series Aftercooler is installed in the compressed air system to reduce the temperature of the compressed air. By lowering the temperature, it condenses the moisture in the compressed air into a liquid state and this liquid moisture is effectively removed through the use of a water separator.

Nitrogen Generator

The unique modular design and energy saving features offer a number of important advantages over conventional nitrogen generators and models that sell nitrogen. The compact system design offers users simplicity, least costly and less disruptive, requiring only pre-treatment of the compressed air system to start production.
