Since entering the market in 1972, Rex Power Magnetics has sold thousands of transformers. Their distinctive blue-and-white units became common fixtures in various industrial and commercial applications across North America. While these transformers were reliable at the time, many Rex installations from the early 2000s now face drops in performance.
ELSCO Transformers addresses these performance issues with precision-engineered systems that add value to your business or organization.
Signs You Might Need to Replace Your Rex Dry Type Transformer
Like all transformers, dry type units manufactured by Rex Power Magnetics will show visible signs of aging as they reach the end of their productive lifespan. Several examples include:
- Increased utility costs: Your monthly electricity bills have consistently risen despite no change in usage patterns.
- Unusual noises: The transformer produces buzzing, humming or crackling sounds.
- Frequent equipment malfunctions: Devices connected to the transformer’s power supply do not function properly.
- Physical deterioration: Visual inspections reveal rust, corrosion or discoloration on the transformer’s exterior.
- Circuit breaker trips: Your facility experiences repeated breaker activations even under normal operating conditions.
Why Select an ELSCO Retrofit for a Rex Transformer Replacement?
Choosing a standard off-the-shelf unit from Rex Power Magnetics or another transformer manufacturer can present various challenges during installation, including:
- Extensive downtime spanning days rather than hours.
- Incorrect impedance that can overstress circuit breakers.
- Costly rewiring of primary and secondary electrical connections.
- Structural modifications to your facility.
- Adding cooling fans or sensors to the stock unit.
Our Rex Transformer Replacements and Retrofits
Our retrofit transformers minimize these challenges with a solution that fits your current setup. Rather than changing your operation to accommodate the transformer, we create custom-designed replacements that precisely match your Rex transformer’s critical dimensions and connection points.
These retrofits are especially beneficial when replacing Rex’s unique designs, such as their space-efficient corner-mount configurations or top-entry cable systems — specialized features that generic replacements simply cannot accommodate.
Our in-stock replacement and retrofit dry type transformers include advanced technology unavailable when your old Rex transformer was built. From copper conductors to precision-wound coils, this technology improves efficiency with the same connection points and other specs for fast installation.
At ELSCO Transformers, we do everything possible to handle all your transformer needs quickly and effectively. In addition to our retrofits and in-stock emergency replacements, we offer a complete lineup of services for medium voltage transformers, from custom bus work to repairs.
