888-910-7543 www.HENEKMFG.com HHV Series “Hi-Vac” Vacuum Dehydrator Process used for dehydrating and degasification of electrical insulating fluids to increase and maintain their dielectric strength As a result of rising cost of oils, increasing environmental regulations, liability and disposal cost, and new stringent vacuum HHV-1800 requirements for manufactures warranties to .4 Torr @ 48hours, it is no longer economical to replace electrical insulating oils with new fluid. Instead, proper treatment of these fluids with our proven Hi-Vac Series renews dielectric strength and lowers residual water content by restoring oils to their original strength through vacuum dehydration & purification. Improvement of the entire insulating media of power transformers is obtainable with our HHV series High New Transformer Vacuum (Hi-Vac) Oil Purifier. Our design meets the operational, economic, and environmental needs of industry and maintains the quality of insulating oils at the time of initial impregnation, filling at the factory, and maintains the same quality in field operation. Our proven Hi-Vac provides reportable dehydration, degasification, and filtration techniques that remove even trace amounts of water to less than 5PPM and gases to less than 0.25%. An easy to read flow chart is provided on the electric panel and is superimposed over all switches, buttons, and indicating/warning lights. Our Hi-Vac can be used as stationary units or manufactured within a variety of trailer configurations to be completely portable or self contained.

This phase is called the “dry out” phase. The task is accomplished by attaching the transformer to a vacuum pump/blower system at the auxiliary connection. Functionality When all leaks on the transformer are sealed to the lowest possible point, vacuum can be pulled on the transformer internals. This is normally the area of ½ to 1 torr (1/2 – 1 micron), the only flow that may enter the vacuum pump must come from the transformer and pass through the cold trap. Any water in the transformer will turn to a vapor (steam) under these low vacuum conditions and freeze as it passes in the cold trap (temperature -80°F to -40°F). It should also be noted that any other liquid contaminants in the transformer that can boil at temperatures equal to or below water may also vaporize and pass through the vacuum system and finally return to a liquid state and move into the atmosphere or the vacuum pump oil. When charged with liquid nitrogen and nitrogen gas, the cold trap is self Skid mounted with containment contained. It is electrically and pneumatically controlled by a single temperature sensing device on the chiller side and is automated to reduce liquid nitrogen consumption during the chilling operation. To thaw the collected water for measurement, the cold trap is equipped with a hot water/glycol solution tank that is heated by a manually activated emersion heater. When activated, the heater increases the temperature of the glycol solution to a preset point before it cuts out and recycles. The glycol tank is equipped with a circulating pump that can be turned on manually to distribute the hot glycol throughout the heating coils (approximately Built into service vehicle Nitrogen Purge Discharge 170°F). The ice is thawed and contained in the cold trap until it can be measured.
