sometimes it is formed as anoil/water Definition: condensate is the liquid formed from water vapour in the air as a result of a drop in temperatureand/or an increase in pressure.Most times it is an oil/water mixture, Compressor Condensate and drinking water resources against Water we have used and contami-nated with oil finds its way back to the natural water courses anddegrades the source of our supply. Rigid legislation exists in mostcountries to protect the environment Discharging oil contaminatedcondensate from compressed air systems is not only harmful to theenvironment, it is probably illegal. The Problem Wh y is oil a oil contamination. The limitsare almost less than 10 ppm oil content! emulsion! This liquid mixes with atmospherichydrocarbon contaminants as wellas oil carried over from lubricated pr oblem? ® â—� â—� â—� User Benefits ecosep SL After the oily condensate has beenefficiently removed from the com- pressed air system it cannot be dis-charged directly to the foul sewerwithout the oil content being reduced to within legal disposal limits.The simple economical and environ-mental solution is a The solution compressors to form an acidic,oilycondensate sludge. A 28.3 m Meet trade effluent discharge regulations Efficiently separates oil and water on-site and returns up to 99.9% of the condensate to foul sewers. Helps to protect and maintain theenvironment oil/water separator. ZANDER 3 /mincompressed air system operating at a pressure of 7 bar g in a 25ËšC, 65%RH environment and fitted with arefrigeration dryer can produce up to 220,000 litres of oil contaminated condensate per year ! discharged to the foul sewerthrough the outlet. The cleaned water can now be safely Oil/water separators are designed toseparate compressor oil from con- densate with high efficiencywithout the use of external power.Oily compressed air condensate should be effectivly removed from the system by a level controlleddrain like the Operation â—� â—� Simple to install, operate and maintain Rapid payback over conventional disposal methods ZANDER ecodrain . Condensate from the system willenter under pressure, into the specially designed centrifugal inlet chamber.Liquid will drop out of the air streamas it impinges on the chamber walls and the vortex generator, draining without turbulence into the primary settlement chamber below.Dirt particles suspended in the con-densate will settle to the bottom of the primary settlement chamber and the accumulating condensate will then flow into the main settlement tank.Entrained droplets of oil dispersedin water will rise to the surface dueto the lower specific gravity of the oil, eventually coalescing to form a thick layer on the surface.An adjustable oil funnel allows theoil to be continuously skimmed off the surface. Drained oil is collected in the external oil container where it can be disposed of according to legal requirements.Cleaner water taken from the bot-tom of the tank flows into the car- bon stage, through a prefilter, into the top of the carbon bags.Any entrained droplets of oil remain-ing are then removed by adsorption.

Large single piece units oil/water separators:the responsible and very economi-cal way to remove and dispose ofoil contaminated compressor con-densate. The condensate should be removed from the compressed air system using a drainage method that doesnot cause emulsification of the con-densate and is appropriate for the unit. Usual methods include : Drain Type T Inseparable using Static Separation: glycol (PAG) inseparable using Staticsystem Diesters, Triesters,Polyoxyalkylene Mineral, Poly alpha olefins (PAO)Trimethylolpropane Ester (TMP), Pentaerythrityl Ester (PE)Band Turbine Oil, Additive Free OilBand affects the efficiency of separation!Band type oil/water separator. The oil type To simplify the selection, lubricantclassifications have been split into three bands depending upon theirability to separate within a static echniques: Automatic transmissionfluid (ATF) C: B: A: A refrigeration dryer installed in acompressed air system can signifi- cantly increase the condensate pro-duced. The oil/ water separatormust be sized appropriately to cope with this extra condensate loading. Flow rates are shown without a refrigeration dryer. The compressorflow capacities must be reduced by 25 % to accommodate the extra condensate produced by the dryer. Refrigeration Dryers *If the use of Timed Solenoid Drainsis unavoidable, steps must be taken to reduce the air loss as this has anemulsifying effect on the condensate. Timed solenoid drains ZANDER recommends the use of the ecodrain range of condensate drains.
