Made from highly refined petroleum oils, Beta Fluid is the industry standard for fire resistant oils.
  • Beta Fluid is Classified by Underwriter’s Laboratories (UL)* and Listed by Factory Mutual for use in transformers located indoors per U.S. National Electrical Code Section 450-23.
  • Beta Fluid has excellent electrical and physical characteristics. It is compatible with standard transformer oil and the transformer materials used with standard mineral oil.

Applications

Beta Fluid can be used in any equipment that uses liquid dielectric cooling oil. Since its introduction in 1994, there are tens of thousands of transformers worldwide that are filled with Beta Fluid. Beta fluid has proven itself in the field and in the laboratory. It’s a safe, proven, and trusted answer to your transformer flammability needs.

Cooling Performance

Beta Fluid has excellent heat transfer characteristics. It’s often used to retrofill transformers that were originally designed for other fluids, such as standard transformer oil.

Processing and Handling

Beta Fluid can be processed, handled and tested in exactly the same way as standard oil, and with the same equipment. Beta Fluid is not toxic or hazardous to workers. Beta Fluid contains no corrosive sulfur. And, unlike soybean vegetable oil – based fluids, Beta Fluid resists oxidation and polymerization.

It’s a one-step retrofill solution to upgrading the fire resistance of standard mineral oil transformers. It’s an excellent choice for original fill for transformers, especially those that will be placed in very cold or very hot environments. It’s made from the same type of synthetic hydrocarbon oils that are used to make synthetic motor oils. Alpha-1® is compatible with standard transformer oil, with PCB fluids, with Beta or R-Temp fluid, and with vegetable fluids. Alpha-1 Fluid® is listed by Factory Mutual for use in transformers located indoors. Made and used since 1992, there are thousands of transformers worldwide that are filled with Alpha-1 Fluid®. Testing shows that the fluid in even the oldest of these units hasn’t changed, darkened, or oxidized. Because of its low viscosity, Alpha-1 cools transformers better than other fire resistant oils. Transformers that were designed for standard transformer oil will not need to be de-rated when retrofilled with Alpha-1 Fluid®. Alpha-1 pours at temperatures down to -55 C. It’s ideal for applications in cold environments, or when a full-load cold start is a possibility. Being synthetic, Alpha-1® contains no sulfur at all.]]> Alpha-1 Fluid® Soltex Alpha-1 Fluid® is an ultra-pure, ultra-clean fire resistant insulating oil.

It is applied to transformers where the oxidation inhibitor content needs to be fortified. Because Inhibit is a liquid, it is simply added to a de-energized transformer. No further mixing or blending is required. Soltex Inhibit is dried, degassed, and highly processed. It is compatible with all brands of standard mineral oil, as well as Beta fluid, R-Temp fluid, Alpha-1 Fluid, and various vegetable oil dielectrics. Five gallons of Soltex Inhibit, when added to 200 gallons of transformer oil will raise the concentration of oxidation inhibitor from 0.0% to 0.30%. Soltex Inhibit has excellent electrical and physical characteristics. It is compatible with standard transformer oil and the transformer materials used with standard mineral oil.

Applications:

Soltex Inhibit is added to transformer oil to raise the oxidation inhibitor content. Soltex Inhibit adds powerful antioxidants to the oil to significantly slow oxidation and deterioration of oil and paper as the transformer ages.

Processing and Handling:

Soltex Inhibit is available in 5 and 55 gallon containers.

Why is Soltex Sulfur Inhibitor a Better Solution?

Corrosive Sulfur is often treated with tolyl-triazole or benzo-triazole compounds. These compounds are called “yellow metal passivators” because they form a coating on metals that contain copper. But this only solves part of the problem! Corrosive sulfur will combine with iron and aluminum, too, and cause similar problems as with copper. A Yellow Metal Passivator does nothing to prevent these reactions. Also, different types of copper in your transformer will react differently with the different types of passivators. If you’re only using one, then you’re not fully protected. Soltex Sulfur Inhibitor stops corrosive sulfur with a three-way attack. It contains a mixture of copper passivators, not just one. This ensures that all types of copper will be protected. Soltex Sulfur Inhibitor also contains a blend of several powerful antioxidants. This protects the oil and paper in your transformer from further oxidation, and inhibits their ability to enter into chemical reactions. Third, Soltex Sulfur Inhibitor contains proprietary compounds that “stabilize” the sulfur in transformer oil. This will make the sulfur less aggressive and lower its corrosive qualities. Taken together, these three actions have far more inhibiting and preventive effect than a yellow-metal passivator alone. This is why we say that Soltex Sulfur Inhibitor stops corrosive sulfur in its tracks.
