Delta HexaVolt: A Compact Solution Designed for Multi-Unit Building Projects
February 23, 2026
In the multi-unit residential construction sector, efficiency and fast installation are key factors in meeting deadlines and staying on budget. Delta has manufactured the HexaVolt transformer, a compact, innovative solution that significantly simplifies electrical installation on job sites.
A Simple Concept, Remarkable Efficiency
Traditionally, powering a multi-unit residential building requires contractors to install three single-phase transformers. This setup means more complexity, more materials, more wiring, and more time on-site.
The Delta HexaVolt completely rethinks this approach by combining three single-phase transformers into a single compact three-phase unit. It delivers the same performance while reducing installation time by up to 66%.
Tangible Benefits of the HexaVolt:
• 66% less installation time: fewer cables, conduits, and supports; just one connection instead of three, for a faster startup
• 38% less footprint: a more compact unit that fits easily in tight electrical rooms
• 20% energy savings: an optimized design that minimizes losses and improves efficiency
Designed for Multi-Unit Building Projects
The Delta HexaVolt was specifically designed to meet the needs of multi-unit buildings, including condos, apartments, social housing, and rental buildings. It enables electricians and contractors to maximize efficiency without compromising on quality or performance.
