MAD SeriesRefrigerated air dryers | Masia Compressors USA
Masia MAD refrigerated compressed air dryers, from 7 to 550 CFM: they deliver dry air with a stable 3 °C dew point and protect pipes, tools and pneumatic cylinders from moisture.

Clean, dry airfor your production
Air leaves the compressor hot and loaded with moisture. As it cools in the network it turns into condensate, which shortens the life of pipes, tools and cylinders, contaminates the final product and raises maintenance costs. The MAD dryer removes that moisture before it reaches your equipment.


- Standard refrigeration cycleIt cools the compressed air to a 3 °C dew point: the water vapor condenses and the drain valves remove it.
- Micro-channel condenserA technology that delivers higher efficiency and high performance. Air-cooled condenser (water-cooled is optional).
- Hermetic systemThe refrigeration circuit is completely closed to the atmosphere, with welded connections only.
- Digi-Pro digital controllerDryer control with a high-temperature alarm and a temperature-driven fan.
- 3-in-1 heat exchangerAir-to-air separator, air-to-refrigerant exchanger and water separator in a single aluminum heat exchanger.
- R513a refrigerantLow global warming potential (GWP 631), zero ozone depletion and non-flammable.
Modelsand capacities
16 models from 7 to 550 CFM. The smaller models use a piston compressor and the larger-capacity ones use a scroll compressor.

How to chooseyour dryer
Selection example
If your compressor delivers 17 CFM at 6 barg, with 40 °C inlet air and a 30 °C ambient temperature:
- 6 barg pressure: factor 0.94.
- 40 °C inlet temperature: factor 0.92.
- 30 °C ambient temperature: factor 0.98.
- 17 ÷ 0.94 ÷ 0.92 ÷ 0.98 = 20 CFM: the model to choose is the MAD-25.
Main components
What the MAD dryer includes:
- Piston compressor (MAD 7 to 60) or scroll compressor (MAD 75 to 550).
- Micro-channel condenser and temperature-driven fan.
- Electric automatic drain valve (loss-free drain optional).
- Condenser dust filter and high-temperature alarm.
- Hot-gas bypass valve on the higher-capacity models.

Frequentlyasked questions
What is a refrigerated air dryer?
It is a unit that cools compressed air to a dew point of about 3 °C to condense and remove moisture, so the air reaches tools, cylinders and processes dry.
What dew point does the MAD dryer deliver?
A stable dew point of 3 °C.
What refrigerant does it use?
R513a: low global warming potential (GWP 631), zero ozone depletion and non-flammable.
How do I choose the model?
Divide your compressor flow by the pressure, inlet temperature and ambient temperature factors; the result in CFM tells you the right MAD model. If you prefer, we will calculate it for you.
