E-SAVER OPAL-R™ series transformers are ultra-efficient dry-type transformers that have been optimized for retrofits applications to deliver up to 80%+ less losses on pre-2007/TP-1 transformer replacements.

OPAL-R models, 80R and 81R, maximize verified energy savings, supporting ESCO, Utility and Commercial Energy Performance Contracts by providing new infrastructure with the fastest payback in the most widespread retrofit applications.

For transformers feeding dedicated equipment like fans, motors and elevators, or heavy harmonic-rich loads, see the E-Saver OPAL™ Series and T1000 OPAL™ Series transformers.

Powersmiths also offers transformers with integrated breakers, for product details see the Energy Station TX™ product information.

OPAL-R™ – Optimized Performance for the Application Load for Retrofits

There is more to a transformer retrofit than simply matching the capacity and input/output voltages with a typical transformer from the distributor’s warehouse. Retrofit applications must also consider site conditions like footprint, internal terminal layout and a transformer’s electrical characteristics that affect fault levels, arc flash risks and inrush currents – which have much more impact on an electrical system than just efficiency.

To address these needs, Powersmiths has developed a transformer design best practice called OPAL™ – Optimized Performance for the Application Load. Our flexible design and manufacturing process enables us to deliver solutions for a wide variety of site conditions and transformer manufacturers including footprint and internal terminal layout compatibility.

The OPAL-R™ series uses the OPAL™ design best practice to address the unique requirements of a retrofit combined with Powersmiths’ Retrofit Best Practice.  

The Retrofit Best Practice ensures energy performance contractors receive verified savings validated by certified meters and Powersmiths’ professional M&V services.
