Product Overview
The heated combined dryer integrates refrigeration and adsorption drying technologies into a single unit. It efficiently removes liquid water in the refrigeration stage-thereby reducing the load on the adsorption stage-and offers the flexibility to operate in either standalone refrigeration mode or a combined refrigeration-plus-adsorption mode, delivering compressed air at varying dew point levels to different points of use. Featuring an integrated skid-mounted design that eliminates the need for a dedicated foundation and simplifies maintenance, this unit is an ideal choice for large-scale factories requiring tiered air supply and energy-efficient operation.
Product Features
Low Energy Consumption
Regeneration air consumption is only 5%–8% of the processing capacity, significantly lower than that of traditional heatless regenerative dryers. The system supports independent refrigerated drying or combined refrigerated and adsorption drying; it can output compressed air at different dew point levels based on specific usage requirements, avoiding energy waste caused by over-drying the entire system.
Centralized Control
All operation switches, valve controls, and display instruments are integrated into a single panel, offering clear, centralized control. Users can flexibly choose between independent refrigerated drying or combined operation based on actual needs, with convenient mode switching.
Dual-Stage Separation
The gas-liquid separator combines cyclone centrifugal separation with filter element interception. Centrifugal force first removes the bulk of the liquid water, followed by a high-precision filter element that captures fine droplets. This ensures high separation efficiency, maximizes the refrigerated drying effect, and protects the adsorbent material from liquid water impact.
High-Quality Valves
The adsorption section utilizes high-quality pilot solenoid valves and pneumatic butterfly valves. These ensure precise operation and smooth switching, guaranteeing long-term, reliable alternating cycle performance for the twin towers and reducing maintenance frequency.
Efficient Heat Exchange
Both the heat exchanger and condenser feature high-quality threaded heat exchange tubes. With ample heat exchange surface area and a high heat transfer coefficient, the system offers superior refrigeration efficiency compared to standard configurations, thereby reducing the operating load on the refrigeration compressor.
Scientific Air Distribution
A three-stage air distribution structure-comprising a diffuser, distribution plate, and airflow distribution pipe-ensures compressed air is evenly distributed to every adsorbent particle. This prevents "channeling" (tunneling effects), minimizes abrasive wear on the adsorbent caused by high-speed airflow, extends adsorbent lifespan, and ensures long-term dew point stability.
Integrated Design
The unit features a skid-mounted layout that rationally integrates the refrigerated and adsorption drying sections into a compact structure. No concrete foundation is required; installation can be performed on any level floor. Maintenance points are easily accessible, significantly reducing the workload for installation and ongoing operation.
Technical Specifications for Heated Combined Air Dryer

Application Scenarios
