Correction factors for SDS range air dryers

Maximum operating pressure : 16 barMaximum ambient temperature : 50CMaximum inlet temperature : 60C

Flow refer to FAD 20C1 barinlet temperature 35Cambient temperature 25C7 barISO8573.1 Class 4

Typical pressure drop : 50 to 250 mbar How to select the right dryer :

Divide the compressor flow by the different

correction factors or multiply the dryer

nominal flow with the different correction

factors.

Ex.: If the nominal flow for a dryer is 100

m/h at 6 bar with an inlet temperature of

40C and an ambient temperature of 30C

your compressor should deliver maxi-

mum :100 X (0.94 X 0.92 X 0.98)=85 m/h.

Cycling Refrigerated Dryers

Why choose a cycling dryer ?

Cycling dryers are designed to SAVE ENERGY . A lot of new compressors

are designed with variable speed controls. The flow varies every minute

according to the need of the plant. Drytec true cycling dryers adapt the

energy consumption to assure energy savings. The average consumption in

the industry is thought to be between 30 and 50% of the full capacity of

the compressors. This means the annual saving can be equal, and the

dryer will pay back itself within a short period.

How does it works ?

Drytec SDC dryers have a water chiller inside. That means that the refrigerant system cools down the wa-

ter/glycol mixture, and stores that liquid in a stainless steel storage tank. A pump is circulating this cold

water through the heat exchanger to cool down and dry the compressed air. If the dryer gets less than

90% of the rated flow, then the machine shuts down generating important energy savings.

Dryers for High Temperature

When choose a SDH dryer ?

Some compressors like piston ones dont have an aftercooler to cool

down the compressed air. Drytec offers a solution for these applications

with its SDH range with an inlet temperature that can go up to 100C.

The integrated aftercooler cools the air down to the ambient tempera-

ture before entering the drying part of the dryer. This solution saves

space and extra cost for a stand alone aftercooler.

This dryer also allows some OEM compressor manufacturers to design

their compressor without aftercooler. This can save space , time and

money.
