Our unique thermal vacuum assisted process safely purifies industrial oils which are contaminated with water, particulates, and gases. Henek’s Lo-Vac units will degas, dehydrate, and cleanse all types of lubricating and hydraulic oils quickly and easily to a safe operational standard reducing costly failures due to contaminated oil.

With the higher cost of oils and ever increasing environmental regulation/liability, and manpower constraints, it is no longer economical to replace your lubricating, turbine, and hydraulic oils when contamination occurs. Restoring these oils to their original strength through purification is more economical and most beneficial to “in service” machinery. Our HLV Series of Low Vacuum (LoVac) Oil Purification Systems are designed specifically to meet the operational, economical, and environmental needs for purifying lubricating oils.

HENEK’s Lo-Vac Systems can be used as stationary units or portable with casters. Systems also custom manufactured within a variety of trailer configurations to be completely portable or self-contained.
