Oil purification unit
max. 7 bar | HNP-021 PALL

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.
