One global OEM shares their story about an OAK Phoenix Expander.
One global OEM shares their story about an OAK Phoenix Expander:
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 small 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 rework
- Reduction of leaks in brazing joints in automated line
- Increase in production
- Similar and better heat transfer properties
Non-Invasive Pressure Expansion Whitepaper
Roger Tetzloff, Innovations Manager of Burr Oak Tool, introduces new technology for high volume production of Round Tube Plate Fin (RTPF) heat exchangers used extensively within the HVAC industry for condenser, evaporator, and heat pump applications.
The trend for increasingly smaller diameter tubes presents a challenge to conventional processes used in joining these tubes to heat exchanger fins.This whitepaper addresses these challenges.
