Founded in Illinois in the 1950s, Olsun Electrics Corporation has established itself as an industry leader with its signature line of custom transformer solutions. Unlike mass-produced models, Olsun units gained recognition for their application-specific designs and use of hybrid cooling technologies. Facilities across North America — from data centers to manufacturing plants — have relied on these transformers for decades.
However, issues emerge as these aging units reach 25 to 30 years in service, creating potential risks to operational efficiency and continuity. To help solve these challenges, ELSCO offers tailored replacement and retrofit solutions designed for your specific application.
Reasons for Replacing an Olsun Dry Type Transformer
An Olsun transformer often shows various signs of deterioration as it approaches the end of its lifespan, including:
- Irregular voltage fluctuations affecting the performance of the connected equipment.
- Deteriorated insulation and terminal connections.
- Unusual noises and vibrations.
- Higher operating temperatures.
- Rising energy bills from decreased efficiency.
Why Replace Your Olsun Dry Type Transformer With a Retrofit Unit?
While products from Olsun Electrics are known for high durability, technological advancements have made many of the older models obsolete. Today’s dry type transformers offer improvements in efficiency, safety and reliability that provide fast returns on investment through lower operational costs and minimized downtime.
When replacing an aging system, facility managers typically consider an in-stock replacement or an engineered retrofit. Standard replacements often require extensive modifications, including rerouting the power feeds, reconstructing the mounting points and rebuilding the enclosures. These extensive modifications sometimes require facility managers to shut down operations for days instead of hours.
ELSCO’s Olsun transformer retrofits eliminate these complications.
Our Replacement and Retrofitting Solutions
ELSCO’s approach to Olsun transformer replacement starts with understanding the specs and wiring of your existing system. Our engineers study the drawings and schematics of your Olsun transformer, including the connection points, dimensions and ventilation system. This detailed assessment helps us create a solution that works with your facility’s current setup.
We can develop custom retrofit solutions that work for installations utilizing Olsun’s specialized designs, including their NEMA 3R outdoor-rated enclosures or their patented forced-air cooling systems. We use premium-grade materials and precision engineering to deliver a transformer that exceeds the original unit’s specifications in both reliability and efficiency.
