HIGH VACUUM DIELECTRIC LIQUID PURIFIERS

DESCRIPTION:  Designed to process and maximize dielectric strength in electrical insulating liquids - including mineral oil, natural esters, synthetic esters, silicone oil and LFH’s (less flammable hydrocarbons) - used in transformers, tap changers, circuit breakers, and other oil-filled electrical devices.

CONTAMINANTS REMOVED:

CLASS II LIQUIDS:  contain excessive particulate, moisture, and dissolved gases.  A basic high vacuum purifier will remove all three of these and return the oil to within specification.

CLASS III LIQUIDS:  contain products of oxidation like acids and sludge that affect neutralization number, color, interfacial tension and power factor.  If these are present, the addition of an optional fullers earth reclamation system is necessary for their removal. 

SYSTEM FLOW RATES:  A wide variety of standard flow rates are available including 75, 150, 300, 600, 900, 1200, 1500, 1800, 2400, 3000, 3600 and 6000 USgph.  All flow rates are adjustable from 0 gallons per hour up to full flow by simply adjusting the outlet valve.  The system automatically internally returns any excess flow to the inlet of the system (automatic re-circulation, single valve operation).

VACUUM PUMPING SYSTEMS:  Are sized for the intended processing method: multi-pass or single-pass to achieve the desired moisture and gas levels.  Vacuum packages suitable for combined oil processing and transformer evacuation are also available.

A variety of pump technologies are available to choose from.  The three most prevalent used are oil-sealed vane pumps, oil-sealed piston pumps and dry-screw pumps.  Any of these can be used in combination with a vacuum booster (roots blower) when the application dictates.

PORTABILITY:  Every system flow rate is available in a stationary model or can be made portable with castors, running gear, shipping container or trailer to suit the intended usage.

ACCESSORIES: A large selection of accessories and features are available including Baron USA’s data logging, remote monitoring, onboard generator, dry air systems, moisture monitors, transformer dry out estimator, and transformer leak test feature.
