Glycol Based Air Dryer
A Glycol Based Air Dryer is an advanced compressed air drying system designed to remove moisture from compressed air using a glycol-based refrigeration medium. It ensures a continuous supply of clean, dry, and moisture-free air, which is essential for protecting pneumatic equipment, improving process efficiency, and maintaining product quality in industrial applications.
This system works by cooling compressed air using a glycol solution as the secondary refrigerant. The glycol absorbs heat efficiently and helps achieve stable low dew point temperatures, making it highly effective for industries that require consistent and reliable air drying performance.
At HiTech Sales & Service, we manufacture and supply high-quality Glycol Based Air Dryers engineered for energy efficiency, durability, and long-term industrial use. Our systems are designed to deliver stable performance even under varying load and environmental conditions.

Working Principle
A Glycol Based Air Dryer operates on the principle of indirect cooling using a glycol solution as the heat transfer medium. The system typically includes an evaporator, glycol circulation system, heat exchanger, compressor, condenser, and expansion device.
1. Glycol Cooling Process
The glycol solution is cooled inside a refrigeration system. This chilled glycol acts as a secondary refrigerant and is circulated through the system to absorb heat from compressed air.
2. Compressed Air Entry
Hot and moisture-laden compressed air enters the air dryer and passes through a heat exchanger where it comes into contact with the cooled glycol circuit (indirectly).
3. Moisture Condensation
As the compressed air temperature drops, water vapor present in the air condenses into liquid form. This moisture is then separated and drained out through an automatic drain system.
4. Refrigeration Cycle
The refrigerant in the system absorbs heat from the glycol solution in the evaporator, causing the refrigerant to evaporate into a low-pressure vapor.
5. Compression and Heat Rejection
The refrigerant vapor is compressed by the compressor and then sent to the condenser, where heat is rejected to the surrounding air or cooling water. The refrigerant then condenses back into a liquid state.
6. Expansion and Recirculation
The refrigerant passes through an expansion device, reducing its pressure and temperature before returning to the evaporator to continue the cooling cycle.
7. Continuous Drying Cycle
The glycol remains continuously chilled and circulated, ensuring that incoming compressed air is consistently cooled, and moisture is effectively removed throughout operation.
