The coil designs of the heating and air conditioning industry have evolved with the conversion to smaller diameter tubing; moving from 3/8” and 5/16” to 7mm and now 5mm as manufacturers continue to experiment in order to reduce manufacturing and raw material costs, as well as improve performance and efficiency.  Burr Oak Tool Inc. has been directly involved with the HVAC industry throughout this evolution, from the first hairpin bender and expander in the mid-1950’s to the 5mm fin and hairpin production of today.

The transition to smaller diameter tubing brings a very different set of manufacturing challenges, and Burr Oak Tool is positioned to deliver solutions to these challenges. OAK innovations in press design, tube processing and fin handling help improve production efficiencies and therefore profitability.  These small diameter tubes, plus other features, have allowed air conditioners to become much less expensive to purchase and operate.      

For over 65 years Burr Oak Tool Inc. has designed customized production machinery for the heat transfer and tube processing industries.  OAK machines are installed and successfully operating in over 70 countries.  Providing quality machines, service and parts to customers worldwide reinforces Burr Oak’s slogan, “Global Experience...Local Solutions.”
