Heated Combined Air Dryer
Product Features
- Low energy consumption: The regenerated gas consumption of the heated regenerated combined dryer is only 5%~8%, saving the consumption of compressed air. Compressed air with different dew points can be provided for different gas points.
- All operating switches and display instruments of the combined dryer are concentrated on the panel of the box plate. According to the different needs of users, the desiccant air dryer can be operated independently or refrigeration and adsorption at the same time. The gas-liquid separator combines two separation technologies, cyclone separation and filter element separation, which can fully separate the cooled liquid water and give full play to the effect of freeze drying. For desiccant dryer part, the use of high quality pilot solenoid valve, pneumatic butterfly valve. Reliable performance, stable switching, accurate action.
- The heat exchanger and condenser of the refrigerated dryer are equipped with high quality and high efficiency threaded tubes. Desiccant dryer part adopts scientific and reasonable twin tower adsorption regeneration structure design. Original compressed air diffuser, distribution plate, airflow distribution tube design, which ensure full contact of the adsorbent and compressed air, and avoid tunnel effect, effectively reduce the impact of high-speed airflow on the adsorbent, reduce the wear of the adsorbent, prolong the life of the adsorbent, and ensure the stability of air dew point. Integrated arrangement, reasonable design, no foundation installation, easy maintenance.

Heated Combined Air Dryer – Integrated Refrigerated & Desiccant Two-in-One Compressed Air Dryer
Heated Combined Air Dryer: 2-in-1 Refrigeration + Desiccant Solution for Wide Dew Point Demand
Core Working Principle & Technical Parameters
This all-in-one dryer unites two mature drying technologies in a single skid-mounted cabinet: the front refrigeration section removes bulk liquid water via cyclone & filter separation, and the rear heated regenerative desiccant tower further strips residual moisture to hit ≤-40℃ pressure dew point. It adopts heatless heated regeneration mode with far lower purge loss than traditional heatless dryers.
Key technical indicators from datasheet:
- Regenerative Air Consumption: 5%~8%
- Pressure Dew Point Output: ≤-40℃
- Inlet Compressed Air Temperature: 10~60℃
- Working Pressure Scope: 0.6–1.0MPa (custom higher pressure available)
- Ambient Operating Temperature: 2~45℃
- Cooling Options: Air-cooled / Water-cooled
- Cooling Water Requirement (water-cooled version): 0.2–0.4MPa pressure, 2~32℃ temperature
- Regeneration Mode: Heatless Heated Regen
3 Core Competitive Product Features
1. Low Energy Consumption & Adjustable Dew Point Output
Traditional heatless desiccant dryers waste 12~18% dry air for regeneration, while our heated combined design cuts regenerative gas loss down to just 5~8%, drastically lowering compressor load and electricity cost.
Users can freely switch operation modes to match different production standards:
- Run refrigeration section alone for general medium-dry air demand
- Activate desiccant tower separately for continuous ultra-dry air supply
- Operate both sections together to achieve stable -40℃ low dew point air
2. Integrated All-in-One Compact & Centralized Control Design
All control switches, gauges and PLC display panels are concentrated on one unified cabinet panel for intuitive one-stop operation.
The built-in gas-liquid separator combines cyclone separation + precision filter element double separation technology, thoroughly removing condensed liquid water to maximize the refrigeration drying efficiency.
The desiccant tower assembly uses high-grade pilot solenoid valves and pneumatic butterfly valves, delivering reliable sealing, stable tower switching and precise action without leakage.
3. High-Efficiency Internal Structure & Low Maintenance
- Refrigeration section: Equipped with premium high-efficiency threaded tube heat exchangers and condensers for fast heat exchange and stable cooling performance.
- Adsorption tower section: Scientific twin-tower regeneration layout, original compressed air diffuser, uniform distribution plate and airflow pipeline design ensure full contact between adsorbent and compressed air, eliminating tunnel airflow defects. It reduces high-speed air impact abrasion on desiccant, extending adsorbent service life and locking steady dew point without fluctuation.
- Installation advantage: Fully integrated skid structure requires no foundation pouring, with standardized pipeline layout for simple daily inspection and component maintenance.
Suitable Application Industries
- Precision electronics, semiconductor and lithium battery manufacturing
- Pharmaceutical, food and beverage sterile packaging production
- Laser cutting, plasma cutting and metal precision machining
- Automated pneumatic assembly workshops & instrumentation air systems
- Printing, coating and plastic injection molding factories
Why Choose Sollant Heated Combined Air Dryer?
- Two technologies in one unit: Replace separate refrigerated dryer + desiccant dryer, saving 30%+ floor space and reducing pipeline installation cost.
- Lower purge air waste: Only 5~8% regeneration air consumption, much more energy-efficient than ordinary heatless desiccant dryers.
- Flexible multi-mode operation: Adapt to changing production dew point requirements without equipment replacement.
