Flowchart
Engineered with premium components, working principle of air-cooled version of FD series guarantees long-lasting durability and consistent operations.
1. Air to air part Heat exchanger
Incoming compressed air is cooled down by the outgoing dry cold compressed air.
2. Integrated water separator
The compressed air is cooled to the required dewpoint by the refrigerant. The water vapor condenses into water droplets.
3. Integrated water seperator
The moisture is collected and evacuated by the electronic zero loss drain.
4. Refrigerant compressor
The refrigerant compressor compresses the gaseous refrigerant to a higher pressure.
5. Oil separator
Filters compressor oil from refrigerant and guides it back to the compressor.
6. Hot gas bypass valve
The hot gas bypass valve prevents the heat exchanger from freezing at lower load conditions.
7. Refrigerant condenser
The refrigerant condenser cools the refrigerant so that it changes from a gas to a liquid.
8. Fans air cooled versions
The fans generate the required cooling air flow.
9. Refrigerant filter
The refrigerant filter protects the entire system from water and solid particles.
10. Expansion valve
The thermostatic expansion valve further reduces the pressure which cools the refrigerant.
The liquid separator ensures that only gaseous refrigerant enters the compressor, avoiding cavitation in the refrigerant compressor.
