Available for rental is the Mobile Filtration System HNP076 of Pall Corporation’s Industry 4.0, a dehydrator for hydraulic oils with a flow rate of 4,200 L/h and a maximum viscosity of 700 cST at 70°C. The system can be remotely controlled, and monitoring is also possible by LubeTeam Hydraulic personnel.
Moisture in Hydraulic Systems
Moisture in hydraulic systems is a threat as it negatively affects machine performance. Water is one of the most severe and destructive contaminants, causing the following damages:
- Viscosity reduction.
- Additive depletion.
- Reduction of the fluid’s lubricating properties.
- Oil oxidation.
- Internal corrosion.
- Abrasive wear of system components.
- Reduced dielectric rigidity.
- Degradation of fluid properties.
Description of the HNP076 Dehydrator and Operating Principle
The HNP076 dehydrator is a portable unit compact enough to be used in confined spaces. With a capacity of 4,200 liters per hour and the ability to remove 40 liters of water per day, it is suitable for medium and large hydraulic systems.
The device allows filtration and degassing of hydraulic systems and lubricating fluids in the offline circuit. It is designed to operate under vacuum (vacuum dehydration is the most effective method, with minimal cost and easy use), allowing the removal of sludge and dissolved water. It can eliminate up to 90% of dissolved water and 100% of free water, 100% of free gases, and up to 80% of dissolved gases. This process occurs without altering the technical, chemical, and mechanical properties of the oil molecule. Contaminant particle removal is achieved using filters with performance ratings of βx(c) >2000 Athalon®. It has a flow rate of 21.8 US gallons per minute (70 l/min = 4,200 lt/hr). Additionally, with the WS12 water humidity sensor, the purifier is allowed to operate only when water exceeds the predetermined level. Water removal rates are influenced by fluid viscosity, temperature, water form (free or dissolved), and the quantity of water present.
The Particle Counter PCM500
The HNP076 dehydrator by Pall Corporation is fully automated. It has an Ethernet connection and is controlled by a PLC with a 5.7” color touch display and a web server for remote control.
The particle counter PCM500, in addition to analyzing hydraulic oils, constantly monitors water saturation in purified fluid. A ventilation filter with colloidal silica dries the incoming air, increasing the efficiency of the cleaning system even in environments with high humidity rates. The electronic contamination sensor allows optimal programming of the use and maintenance of the filter element for particle removal. For protection against overpressure, the gear pump is equipped with a safety valve set at 3.5 Bar g (350kPag/50.8 psi max). After startup, it operates completely automatically. The standard water sensor enables permanent control of fluid water saturation.
