Air dryer

The air compressed by a compressor contains water vapor, and when a 100L air tank contains compressed air at 0.7MPa, the inhaled air is compressed to 1/8. It becomes. Since water vapor does not change in size, it becomes eight times as large and cannot be contained in the air, condensing and forming condensation (water). Also, if that air cools even a little, it will condense and new condensation will occur. This drain (water) can cause repelling during painting and has a negative effect on the machine's air cylinders, valves, and solenoid valves, so it is necessary to remove the water. An air dryer is a machine that removes moisture from compressed air.

Refrigerated air dryer

Standard model compatible with 37kW or less

RDG series

Refrigerated air dryer is the most standard air dryer for compressed air.
A refrigerator is used to compress and liquefy the refrigerant, and the heat of evaporation cools the compressed air, and the difference in the amount of saturated water vapor removes condensate and dries the compressed air.
It is also possible to remove moisture from oil-containing compressed air.
