OIL PURIFICATION SYSTEMS MODEL VPH OIL PURIFICATION SYSTEMS FOR ELECTRICAL LIQUIDS The FILTERVAC high vacuum thermally accelerated degasification process is a widely accepted and more economical method of treatment of electrical insulation fluids to increase and maintain their dielectric strength. The processing includes the removal of free and soluble water, free and dissolved air and gases and particulate matter. They VPH System upgrades the new or used electrical insulating liquids including transformer oils, askarels or polybutenes. The proper treatment and upgrading of the properties of the insulating media are essential for present and future transformer requirements. APPLICATIONS The foremost applications of high vacuum purification systems are in the field of extra high voltage transmission and in the manufacture of electrical apparatus for it. The VPH System is ideal for drying and filling new transformers at both the factory test and during field installation. In addition the VPH System is designed for reconditioning of insulating oils in service. Many other applications for the high vacuum process exist such as its use in the degasification of cable oils including polybutenes. Outside of the electrical industry this process is used for degasification and dehydration of oils for radar and electronic equipment, vacuum pump seal oils, brake fluids, refrigeration oils - including phosphate esters and silicones. Please contact Filtervac for more details about our line of Cable Oil Purifiers (Model VPH-EC) or for all applications outside of the electrical industry. CHARCTERSTICS OF A VPH SYSTEM FILTERVAC offers standard models with processing capacities ranging from as small as 50 USGPH (189 L) to as large as 3000 USGPH (11340 L). [Filtervac is able to manufacture larger units as well as custom designed systems to meet all the customers’ requirements.] The VPH System is designed as a self contained unit, mounted on a common base, fully assembled and ready for connection. The VPH System includes a filter, oil heater, vacuum chamber, oil and vacuum pumps and instrumentation. The control panel contains; vacuum and pressure gauges, switches, indicating lights, indicating temperature controller and alarm. The vacuum chamber is designed to maintain a vacuum of 1 TORR or less throughout the entire purification process. Oil at ambient or elevated temperature is introduced into the vacuum chamber where, by vacuum distillation, water, dissolved air and gases and other low boiling- range volatile contaminants are removed. The oil level is controlled by a fully modulating float-actuated level control valve and foam control is supplied as a standard feature. The processed oil is removed from the vacuum chamber by the discharge pump and returned to the transformer as purified oil. MOBILE SYSTEM WITH WALK IN CAPABILITIES MODEL: VPH-M-2400 Stationary System Model: VPH-S-400 OPTIONS/FEATURES • STATIONARY, MOBILE, TRAILER MOUNTED • FLOW RATES FROM 50 TO 3000 IGHP • OPTIONAL FULLERS EARTH TREATMENT • FULLY AUTOMATED OPERATION PERFORMANCE The VPH system meets the following performance specifications in a single pass through. DEHYDRATION - At minimum oil temperature of 80 F(27 C), the soluble water content is from 100 PPM less than 10 PPM or from 50 PPM down to 5 PPM by ASTM Method D-1533. DEGASIFICATION - Total soluble air content reduction in a single pass from full saturation at 10 - 12% by volume to 0.25% by volume by ASTM Method D-2945. Other gases in solution with oil are also removed. PARTICULATE MATTER - Removed to a nominal 5 microns, with afterfilter to 0.5 microns. DIELECTRIC BREAKDOWN - Minimum 40 KV by ASTM Method D- 877.
