Hy-Pro Donaldson - Model COT -Turbine Oil Conditioning Skids System

Oil from the system entering the COT through a positive displacement gear  pump passes through low watt density heat to achieve the optimum turbine oil temperature for efficient liquid-liquid separation by coalesce, >100°F (38°C). The first stage of oil conditioning is particulate removal by β5[c]>1000 high efficiency glass media element. Next, the oil enters the two stage coalesce vessel where the oil passes through 100% synthetic media coalesce elements. The free and emulsified water coalesces to form larger droplets that overcome the specific gravity of the oil and drop to the bottom of the vessel. Stage two in the coalesce vessel is the separator/post-filter element that functions as a water barrier for emulsified and small droplets of water that have not reached a size large enough to drop of suspension. After passing through the water barrier, the oil passes through a final stage of particulate removal filtration by β2.5[c]>1000 media to achieve even lower operating ISO Codes. The coalesce vessel will achieve single pass water removal from 5000 ppm to <150 ppm under normal operating conditions and oil health. As water collects in the bottom of the coalesce vessel, a specific gravity float reaches a limit indicator that will open the automatic water drain valve and eject the separated water as it is removed to allow for 24/7 continuous operation. When fitted with a totalizing meter on the water drain line, quantity and timing for water removal can be established.
