Standard practice is to follow the compressor element with an after cooler of sufficient capacity to reduce the temperature to within 10\u00b0C of the temperature of the cooling water or air. In the former case, approximately 20 litres of water will be required for every 2.5 m3 of free air being cooled. Further cooling is possible if a reasonably large receiver is fitted.  <\/p>\n<p align=\"justify\">Refer to the chapter on Air Receivers to assess the proper volume. It is often quoted that the size of the receiver should be approximately equal to 30 times the rated free air deli very of the compressor, for 7 bar applications. A receiver should incorporate a condensate drain, preferably of an automatic type.  <\/p>\n<p align=\"justify\">Further cooling is likely to occur in the distribution main, so these should be laid out with a pitch in the direction of flow so that gravity and air flow will carry the water to drain legs, located at appropriate intervals. These also should be fitted with automatic drain valves to prevent them being flooded. Down loops in the distribution main should be avoided where possible, but if this cannot be avoided, they mustincorporatedrain legs at the bottom of the down loop. All take-off points from the distribution main should be located at the top of the main to prevent water getting into the take-off line.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Water vapour Ambient air always contains water vapour.
