Refrigerated Type – HRD Compressed Air Dryers
- 3°C pressure dew point
- Very Low Pressure Drop
- Designed for Tropical Conditions
- Dryer easily runs at 60°C Max. Inlet Temp. and 50°C Ambient Temp.due to R134a refrigerant (all through the range) and oversized condenser.
As the canopy of the dryer is designed not to leave any unused space inside, HRD series air dryers cover minimal space where they are placed.
Energy Saving Device
Digital Controller with a lot of economy features and alarm capabilities is standard for all 3Ph dryers
(HRD140 and up)
Aluminum Heat Exchanger is Standard
(From HRD 40)
Very Low Pressure Drop (100mbar)
Very Efficient (3oC real pressure dew point)
Scroll Compressors(from HRD 120)
Scroll Compressors which are energy efficient and durable against liquid shocks are employed.
Easy to access in to the cooling components in seconds
by the help of Screw free panels and plastic handles.
Electrical wires are seperated from Refrigerant Side
No electrical wires inside the refrigerant side of the dryer. Electrical Box has an external cover which has an access from the outside of the dryer. No need to open dryer panels to go in to electrical box.
Example for choosing the correct HRD air dryer model;
If a compressor delivers 200 m3 / h at 6 bars, the dryer inlet temperature is 40OC and the ambient temperature is 30OC, please choose your dryer as follows;
Dryer Capacity / 200 / 0.94 / 0.92 / 0.98 =236 m3 / h
The correct dryer model for this application is HRD 80.
