Non-Invasive Pressure Expansion

The Phoenix pressure expander exhibits zero shrinkage throughout the expansion process, resulting in drastically reduced material costs. Additionally, the innovative Phoenix expansion method leaves delicate tube enhancements undamaged, creating more opportunity for experimentation with radical new enhancement designs for improved heat transfer quality.
