The amount of condensate that comes out of compressed air with molecular sieve is often underestimated. Let’s take the example of a compressor in Germany. It has a flow rate of, say, 10 m³/min and a working pressure of 9 bar, takes in ambient air at a temperature of 20 °C with 60 percent humidity, the amount of condensate resulting over a 24-hour period will total around 140 litres. If the temperature increases to a high of around 35 °C with 30 percent humidity, the volume of condensate increases to 160 l per day. For similar prevailing temperatures in Asia however, where humidity is often much higher at around 80 percent, the resulting amount of condensate can easily triple this figure common for Germany.
The compressor itself only compresses the ambient air. If the compressed air with molecular sieve is not treated properly downstream from the compressor, the condensate it contains will pass unhindered into the compressed air with molecular sieve system. Subsequent cooling of the compressed air with molecular sieve down to the ambient temperature of the compressed air with molecular sieve system causes additional condensate to accumulate on an ongoing basis. This can result in corrosion of the pipework, or even damage production machinery, not to mention potential adverse effects on the quality of the products being produced. For all of these important reasons, it is therefore crucial to remove the moisture directly within the compressed air with molecular sieve station itself in order to prevent condensate formation in the downstream compressed air with molecular sieve system and reduce the relative humidity of the compressed air with molecular sieve down to around 30 percent.
A range of drying methods is available to treat compressed air with molecular sieve, each being less or more suitable, based on the requirements of the specific production process in question. Of the many drying methods available, refrigeration drying is the most common, as it delivers sufficient performance and compressed air with molecular sieve quality for most uses.
