The HNP-021 has been developed as a conditioner for hydraulic, lubrication and dielectric oils. It removes free and dissolved water, dirt, and free and dissolved air/gases. This portable unit is compact and easy to use. The HNP oil purifier provides a wide range of opportunities for cost savings including: increased equipment uptime, improved machine performance, reduced component replacement costs, reduced maintenance labor costs, and lower oil replacement and disposal expense.
The Pall HNP fluid conditioning purifier removes 100% of free water and as much as 80% of dissolved water. It also removes 100% of free and entrained gases and up to 80% of dissolved gases. Particulate removal is achieved using a high Beta rated (ß5(c)=1000) Ultipor® III filter element to polish the fluid before discharge back to the system reservoir. Other replacement filter media grades are also available to suit application requirements.
The HNP can be moved from one system to another or left as a permanent installation. The HNP purifier is simply connected to an electric supply, the inlet valve opened and “reset” and “start” buttons pressed to start the fluid purifying process.
Automatic controls, integral to the unit, constantly monitor the operation and will safely shut down the system if fluid levels and pressures are outside normal limits.
Safety features include high and low level float level switches, discharge relief valve (set at 100 psid/7 bar), inlet oil vacuum pressure switch and drip tray float switch.
The HNP fluid conditioning purifier has been designed to be robust and reliable under the most arduous of conditions. All components are easy to maintain and filter elements are readily accessible for change out.

HNP 021 Performance
The HNP purifier is designed to reduce and maintain the water content in a fluid system to below the saturation level of the system fluid (<300 ppm for a typical mineral oil). However, where a large water ingress occurs, the HNP 021 can remove up to 12 gallons (45L) per day. Actual water removal rate depends on many variables including system design, oil type, temperature, viscosity, water content, emulsion stability, and additives.
