SSD Series Refrigerated Dryer

Distinguished from the carbon steel material products, SSD heat exchanger assembly and air receiver are all made of 304S stainless steel, which will not cause secondary pollution to the quality of the air used, and can directly serve the food, medicine, electronics, advanced spraying and other industries.

PD Series Refrigerated Air Dryers

The pre-cooler, evaporator and gas-liquid separator adopt integrated design; Special thickened alloy aluminum heat exchanger assembly, corrosion resistance is much higher than similar designs at home and abroad; different from the products made of carbon steel, it will not cause secondary pollution to the quality of gas; The surface of the wind condenser is coated with nanometer anticorrosive coating to prolong its service life; The heat exchanger adopts plate-fin structure advanced in Europe and America, with high efficiency.

ST Series Refrigerated Dryer

High quality compressor with multiple protection settings. Patented WS water separator ensures ultra-high dew point. 8~10°C temperature difference between inlet and outlet water of pre-cooler ensures minimum outlet RH and prevents orifice freezing, which is much better than similar products. The pre-cooler recovers more than 90% of the cooling capacity and effectively reduces the load on the evaporator, so that the total energy consumption is only 85% of that of similar products.

HT Series High Temperature Refrigerated Air Dryer

Designed to handle inlet temperatures up to 80°C. Environmentally friendly HFC refrigerants R134a and R407C. Large pre-cooler and counter flow design for energy savings of up to 25%. Demisting water separator with 99+% efficiency dew point guarantee, much better than cyclone separators. Rugged hermetic refrigeration compressor provides years of trouble-free service. Automatic refrigeration temperature control system maintains precise refrigerated air temperature. Various power supplies available.

HP Series Refrigerated Air Dryer

The refrigerated dryers in the HP series units feature a powerful cooling system. This includes a high-quality refrigerant compressor, large-sized heat exchanger surfaces and a cleverly designed cooling airflow. This combination thus ensures reliable operation even at high temperatures and guarantees a consistently stable pressure dew point.

RSXB-ZP Series Zero Air Consumption Blast Air Heating Regeneration Adsorption Desiccator

The RSXB series of blast air heated regenerative adsorption dryers use highly efficient and durable, low power consumption blowers and heaters to thermally regenerate the adsorbent at high temperatures using ambient air without consuming the finished drying air in 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 strict requirements. The RSXB series of blast heated regenerative adsorption dryers are designed for a constant pressure dew point of -40°C (pressure dew point -70°C optional).

RSXB Series Micro Air Consumption Blast Heating and Regeneration Adsorption Desiccator

The RSXB series of blast air heated regenerative adsorption dryers use highly efficient and durable, low power consumption blowers and heaters to thermally regenerate the adsorbent at high temperatures using ambient air without consuming the finished drying air in 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 Jih-Sun's strict requirements. The RSXB series of blast heated regenerative adsorption dryers are designed for a constant pressure dew point of -40°C (pressure dew point -70°C optional).

RSXY-ZP Series Zero Gas Consumption Compression Heat Regeneration Adsorption Dryer

RSXY series compression heat regeneration adsorption dryer makes full use of the heat generated by the compressor to thermally regenerate the adsorbent, which is a kind of adsorption dryer with remarkable energy-saving characteristics. It can only be used with oil-free lubricated air compressors (centrifugal air compressor, oil-free screw air compressor, oil-free piston air compressor, etc.). RSXY series compression heat regeneration adsorption desiccant dryer is designed for constant -20℃ pressure dew point (pressure dew point -40℃ is optional).

RSXY series compression heat regeneration adsorption desiccant dryer is designed for constant -20℃ pressure dew point (pressure dew point -40℃ is optional).

RSXW Series Heatless Regeneration Dryer

The bottom of the adsorption tower adopts supporting ceramic ball, 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 specially designed high performance desiccant can obtain the best dew point. The standard configuration of the whole series is high-performance pneumatic valve, when it runs, the reliability and pressure loss are obviously better than membrane valve and solenoid valve.

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 allows the moisture in the compressed air to be condensed 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 means for the user that installation is simple, least costly and less disruptive, requiring only pre-treatment of the compressed air system to start production.
