The HLP series combines the water removal performance of mass transfer purifiers with high reliability and ease-of-use to help ensure maximum equipment uptime and lowest cost of ownership. This enables you to focus on your process, not on your equipment.
Improved PerformanceThe Pall HLP series purifiers feature an innovative new vacuum tower design that maximizes water removal efficiency.
Maximum Reliability, Lower Cost of OwnershipHLP series purifiers are designed for maximum uptime and have proven themselves in the field with industry-leading utilization rates even in the most demanding and continuousduty applications.
The HLP50 uses specially selected components to help ensure maximum reliability and lower cost of ownership. These premium components include:
- Best-in-class Allen Bradley PLC
- Reliable Elmo Rietschle vacuum pump with 12-month service interval
Controlling the dissolved as well as the free water in the reservoir is critical in ensuring the absence of free water during operation. With the Pall HLP50 purifier, this is done efficiently, easily, and reliably. The diagram below illustrates the concept.
Ease of UseThe HLP50 series offers the following features to increase versatility in service and lower cost of ownership:
- Low maintenance
- Able to work with wide range of oil viscosities (3 cSt to 700 cSt)
- No utility water required for cooling or pump operation— the only utility needed is an electrical power source
Standard FeaturesPall HLP series purifiers come with the following standard features that many suppliers charge extra for:
- Dissolved water sensor (Pall model WS10)
- Low-watt density heater (30kw output)
- Condenser with gravity drain
Focus on your Process, Not on your PurifierHLP Series purifiers require a minimum of user interaction, which allows customers to focus more on their process and less on maintaining and upkeep of their purifier.
The HLP purifier is one of the easiest purifiers to operate. Simply connect the purifier to the reservoir, power up, and press the start button. In fact, many HLP users are able to just “press the button and walk away.”
- Extended vacuum pump oil change interval—12 months (8760 hours of run time)
- No water utility for cooling or pump operation

The Pall HLP Series of purifiers has a new vacuum tower design that maximizes water removal (see chart below). The HLP50 removes 100% of free, un-dissolved gases and water (under steady state conditions), and up to 80% of dissolved gases and water. It also removes solid contaminants with efficiency of 99.9% (down to 3 microns).
HLP Series oil purifiers showed a 40% faster dehydration rate when compared with a typical purifier.
