Hevi-Duty transformers have served countless industrial and commercial transformer applications requiring reliable power conversion for decades. However, as these transformers age, challenges start emerging due to material degradation, parts availability and compatibility with modern systems. ELSCO Transformers offers precision-engineered retrofits and replacements that integrate with your existing transformer infrastructure while providing enhanced reliability and performance.
Why You May Need to Replace Your Hevi-Duty Dry Type Transformer
Older Hevi-Duty transformers often develop insulation weaknesses that create imbalances with the current and trip breakers frequently. These disruptions typically increase in frequency as the transformer approaches the end of its service life. Signs that your insulation is deteriorating range from visible discoloration and cracks to rattling and humming noises.
Have you noticed increased operational temperatures during normal loading conditions? Hevi-Duty encapsulated models often develop thermal management issues as the internal components and materials age and degrade. When surface temperatures exceed manufacturer specifications, replacement is necessary for the safety of your facility.
Additionally, following the acquisition by Emerson and transition to the SolaHD brand, many older component specifications changed. These changeovers have complicated the maintenance of legacy units, especially for specialized models manufactured before 2010.
Why Choose an ELSCO Retrofit Transformer to Replace Your Hevi-Duty Unit?
When replacing an existing Hevi-Duty transformer, facility managers and maintenance supervisors often discover that most standard units don’t physically or electrically align with their existing setup. ELSCO’s retrofit transformers eliminate these challenges by modifying an in-stock unit to match your requirements.
Our engineers will document the dimensional and electrical characteristics of your existing Hevi-Duty transformer, including:
- Physical dimensions and mounting configurations.
- Terminal locations and connection types.
- Electrical specifications and voltage regulation characteristics.
- Load response behavior under your facility’s specific conditions.
Using this information, we create a cost-effective, highly efficient replacement that integrates seamlessly with your existing infrastructure while addressing the limitations of the original Hevi-Duty design. Each unit undergoes comprehensive testing to verify electrical performance and dimensional accuracy before shipping. Besides retrofits and in-stock emergency replacements, we offer several other value-added services, including specialty bus work, custom-built units and transformer repairs.
