Product detailed description
The Mikropor MOK-100 refrigeration dryer with GO-131 filters dries compressed air to a pressure dew point of +3 °C, and the pair of filters on its rear wall removes dust and oil aerosol. It handles 1,667 l/min (100 m³/h) at 7 bar, works up to 14 bar and is connected at the filters with a G 3/4" thread; power supply 230 V, 1 phase, 50 Hz.
It belongs to the Mikropor MOK refrigeration dryers with R513A refrigerant. The same dryer without filters is MOK-100.
Technical parameters
| Parameter | Value |
|---|---|
| Flow rate at 7 bar | 100 m³/h (1,667 l/min) |
| Working pressure | 4 to 14 bar |

| Room temperature | +5 to +50 °C |

Pair of filters
| Grade | Particle removal | Residual oil | Initial pressure drop |
|---|---|---|---|
| X – dust filter | 1 µm | 0.1 mg/m³ | 80 mbar |
| Y – microfilter | 0.01 µm | 0.01 mg/m³ | 100 mbar |
Two GO-131 filters are connected by a manifold on the rear wall of the dryer. Downstream of the dryer the air first passes through the X dust filter, which removes particles down to 1 µm and reduces oil content to 0.1 mg/m³, and then through the Y microfilter, which removes particles down to 0.01 µm and reduces oil content to 0.01 mg/m³. The MO-131 X and MO-131 Y elements are replaced at a pressure drop of 700 mbar, without tools.
Dimensions
The dryer is 338 mm wide, 333 mm deep and 531 mm high. The filters are on its rear wall, which makes the set deeper; we will state the exact dimensions of the set once the manufacturer confirms them.
Flow rate under other conditions
The nominal flow rate of 1,667 l/min applies to +35 °C inlet, +25 °C room temperature and 7 bar. Under other conditions multiply it by the manufacturer’s correction factors. For example, at +40 °C inlet, +30 °C room temperature and 10 bar, MOK-100 handles 1,667 × 0.92 × 0.98 × 1.11 = 1,668 l/min.
Inlet air temperature factor
| Temperature °C | 30 | 35 | 40 | 45 | 50 | 60 |
|---|---|---|---|---|---|---|
| Correction factor | 1.29 | 1.00 | 0.92 | 0.78 | 0.65 | 0.45 |
Room temperature factor
| Temperature °C | 20 | 25 | 30 | 35 | 40 | 45 | 50 |
|---|---|---|---|---|---|---|---|
| Correction factor | 1.05 | 1.00 | 0.98 | 0.93 | 0.84 | 0.76 | 0.70 |
Pressure factor
| Pressure bar | 4 | 6 | 7 | 8 | 10 | 12 | 14 |
|---|---|---|---|---|---|---|---|
| Correction factor | 0.80 | 0.94 | 1.00 | 1.04 | 1.11 | 1.16 | 1.22 |
The dryer operates from 4 to 14 bar, with inlet air at +5 to +60 °C and in a room at +5 to +50 °C.
How it works
The air is pre-cooled in the 3-in-1 heat exchanger, the refrigerant cools it to a dew point of +3 °C and water vapour condenses; the separator captures the droplets and the drain discharges them. On its way out the dry air is reheated, so no water condenses on the pipework.
Equipment
The Digi-Pro controller shows the temperature, dryer and fan operation and reports alarms and service. The time-controlled drain can also be triggered manually with a button. The microchannel condenser has a debris filter and a temperature-controlled fan; the refrigerant circuit is hermetic.
R513A refrigerant
R513A refrigerant does not deplete the ozone layer, is non-flammable and its global warming potential is less than half that of R134a.
Where to install it
The dryer with filters goes after the compressor and the air receiver and delivers dry air free of dust and oil aerosol. For air free of oil vapour and odours add an activated carbon filter after it; for a dew point below 0 °C there are desiccant dryers.
