ADRY TAC desiccant dryers with activated carbon tower

Activated carbon tower Omega Air A-DRY TAC desiccant dryer with activated carbon tower and filters

Omega Air ADRY TAC desiccant dryers dry compressed air to a pressure dew point of −40 °C and at the same time remove oil vapours and odours from it. In addition to the two desiccant columns of the ADRY dryers, they have a third column with activated carbon that captures oil vapours by dry separation.

8 sizes from 6 to 150 Nm³/h (100 to 2,500 l/min) for pressures of 4 to 16 bar. A 0.01 µm inlet microfilter and a 1 µm outlet dust filter are included.

Sizes and technical data

The inlet flow is the nominal flow the dryer can dry; the outlet flow is lower by the regeneration air. Dimensions with filters (A*, B*, C*) apply to the dryer with inlet and outlet filter, as supplied.

Dimensions of the ADRY TAC desiccant dryer: height A, width B, depth C and dimensions with filters — Dimensions A, B, C without filters and A*, B*, C* with inlet and outlet filter; D is the foot spacing

The nominal flow refers to intake air at 1 bar(a) and +20 °C at a working pressure of 7 bar, an inlet temperature of +35 °C and a pressure dew point of −40 °C at the outlet. If the dryer runs without the inlet filter, the incoming air must meet class 1 according to ISO 8573-1 for solid particles and oil.

How to choose the size

The dryer must handle the actual flow of the compressor at your pressure, inlet temperature and required dew point. Multiply the nominal inlet flow by the manufacturer’s correction factors and choose the size that gives the same as or more than your flow.

Actual capacity = nominal inlet flow × F1 (pressure) × F2 (inlet temperature) × F3 (dew point)

Factor F1 – working pressure

Factor F2 – inlet air temperature

How the ADRY TAC dryer works

The two desiccant columns work just as on ADRY dryers: one dries while the other is regenerated with a small portion of the already dried air, and they swap every 10 minutes.

The dried air then passes through the third column with activated carbon. The carbon captures oil vapours and odours from it.

The design of the columns and control blocks and the maintenance procedure are the same as on the ADRY dryers, where you will find them described in detail.

Control unit

In the basic version the control unit shows its status with six LEDs, dryers with energy-saving dew point control have a control unit with a display.

Ventilek’s tip

Size the dryer from the actual compressor flow and do not forget the pressure correction: at 6 bar the dryer has only 88% of its nominal capacity.

Replace the 1, 2 and 4-year kits according to the years of operation.
Dryers without the third column are in the ADRY desiccant dryers category.

What does the ADRY TAC dryer remove in addition to the ADRY dryer?: Oil vapours and odours. They are captured by the third column with activated carbon, while the two desiccant columns dry the air to a dew point of −40 °C.
Are the filters included?: Yes. The dryer has a 0.01 µm inlet microfilter and a 1 µm outlet dust filter.
How much air does regeneration use?: 15 to 20% of the air on average. The outlet flow in the table shows how much air remains for the air line.

Data according to the manufacturer Omega Air. Dimensions and flows are nominal values, actual performance depends on operating conditions.

Other types of drying can be found in the compressed air dryers category.
