Phoenix Pressure Expander
Phoenix Pressure Expander
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.

Phoenix Expander Case Study
Global OEM indicated that expanding smaller diameter (5mm & 7mm) tube coils was exponentially harder than expanding other larger diameter tubes, causing substantially higher scrap rates of smaller diameter coils.
Unacceptable production scrap rate related to compression expansion.
Unnecessary rework on the belling and flaring operation.
Bottle neck of production at the expander, cycle time.
Valuable production loss due to tooling changeovers and wrecks.
Global OEM explained desired expansion parameters and production expectations, and Burr OAK Tool implemented the Phoenix Pressure Expander.
When compared to conventional expansion methods, the Phoenix has improved workflow, reduced plant footprint and enabled greater research of small diameter coil design, due to Phoenix success.
Production scrap rate reduction.
Copper savings due to Zero-Shrink.
Eliminated bell and flare related work.
Reduction of leaks in brazing joints in automated line.
Increase in production.
Similar and better heat transfer properties.
