Pall Oil Coalescers
Pall HCP200 Turbine Oil Purifier
The Pall HCP200 turbine oil purifier can be used to remove both particle contamination and free water in turbine oils. When oil enters the coalescer unit, after particle filter, its point of contact is the coalescer elements. Free and emulsified water become larger droplets of water after passing through the filter elements due to the peculiar polarity molecules in the coalescer element materials. Before the oil enters the separator element, gravity causes the relatively large water drops in the oil to fall into the water bag below.
However, as a result of inertia, some water droplets go up to the separator element along with the oil. The separator element is made up of special hydrophobic materials, so that when the oil passes it, water droplets are kept outside,” explains Whitcher, continuing: “The oil then enters the separator element and discharges from the machine outlet. Water droplets gather and become larger and at last, they fall into the water bag. Once the water bag reaches a level of 221 mm, it discharges the free water through its own outlet pipe.”
After debugging, the unit can run smoothly during normal operating conditions and requires no manual operation. It is equipped with an emergency alarm, which will automatically sound when abnormal conditions occur or when maintenance is due and, in case of an emergency, the automatic emergency stop will shut down the system.
The HCP200 also comes with a host of functionalities and benefits. It can be used independently as a solid particle filtration unit, which therefore means that it can bypass the coalescer function if water removal is not required. The unit uses high performance Pall Coralon filters, which incorporate state of- the-art design technology, including a unique patented ‘helical wrap’ pleat support system, as well as composite element structure for unsurpassed strength, optimum performance and service life.
