Delta HexaVolt
Multi-Unit Buildings Distribution Transformers
Delta HexaVolt is designed to simplify and improve electrical systems in multi-unit apartment buildings. By combining three single-phase transformers into one efficient unit, this innovative solution cuts down on installation time, saves space, and enhances energy efficiency.
Key Benefits
38%
LESS SURFACE AREA*
The compact design minimizes space and reduces heat rejection, making it easier to fit within electrical room constraints.
20%
ENERGY SAVINGS*
Operating on a three-phase system, this transformer is more efficient than 3 single-phase systems used at full load, leading to lower energy consumption and cost savings over time.
66%
LESS INSTALLATION TIME*
With just one transformer to install, the process requires less time and fewer materials, reducing overall installation costs.
*When compared to three single-phase transformers.
Traditional Setup vs. Delta HexaVolt Solution
Single-phase transformers are commonly used to power multi-unit residential
buildings. Typically, this set-up involves three transformers, multiple anchors,
three switches, and numerous bulky cables, cluttering often cramped electrical rooms.
The HexaVolt transformer simplifies this set-up with a compact, all-in-one
solution that includes one three-phase transformer, three single-phase outputs
and requires only four anchors, and one switch.
