Fuel Oil Water Separator
Products Description
Product Characteristics
The low-temperature dry compressed air separated from the condensed liquid flows back into the pre-cooler from the gas-water separator, where it exchanges heat with the incoming high-temperature wet compressed air as mentioned in Process 2, absorbing heat and raising its temperature to near room temperature, which effectively prevents the low-temperature dry air from generating condensation water when passing through the external pipeline and affecting the gas quality. After leaving the pre-cooler, the reheated dry compressed air enters the post-filter, which is equipped with a fine filter element with a higher precision than the pre-filter, usually with a filtration accuracy of 0.1-1μm. The post-filter further removes trace solid particles, residual oil mist, and a small amount of unseparated fine water droplets that may still exist in the dry air, further improving the cleanliness and dryness of the compressed air. This step is the final purification link of the compressed air, ensuring that the discharged air meets the dryness and cleanliness standards required by industrial production.
Working Principle
The amount of water vapor in the compressed air is determined by the temperature of the compressed air: under the condition that the pressure of the compressed air is basically unchanged, reducing the temperature of the compressed air can reduce the content of water vapor in the compressed air, and the excess water vapor will condense into liquid.

Our Service
For sudden mechanical or electrical failures that cannot be resolved remotely, we provide efficient on-site emergency repair service. Once a fault is confirmed, our after-sales dispatching center will immediately assign nearby certified engineers to rush to the site within the promised time. Engineers carry professional tools and commonly used spare parts to quickly diagnose problems such as compressor damage, expansion valve failure, fan burnout, refrigerant leakage, or control system faults. They prioritize temporary restoration of equipment operation and then complete thorough repairs. After maintenance, full functional testing is conducted to ensure dew point, pressure, and temperature meet standards. This service greatly shortens downtime and ensures continuity for pneumatic systems, assembly lines, and processing equipment.
FAQ
1. Q: How to select dryer model?
A: Based on max air flow, inlet temp/pressure, required dew point.
2. Q: Advantages of VFD dryer?
A: Energy saving at low load, stable dew point, low failure rate.
3. Q: Energy saving tips?
A: Ensure good ventilation, clean heat exchangers, use zero-air-loss drains, match load.
4. Q: Difference between high-temp and standard dryer?
A: High-temp model withstands higher inlet temperature without capacity loss.
