Dayton, OH:  DELTA H® recently supplied twin SCAHT®-HD (Heavy Duty) Series convection furnace systems to Winston Heat Treating.  The furnaces replaced older tempering systems that were extremely difficult to qualify to even Class 5 (+/- 25F).  Pyrometry expert Andrew Bassett of Aerospace Testing and Pyrometry (ATP) recommended to Winston Heat Treating management the acquisition of DELTA H furnaces as “the easiest furnace brand to qualify and maintain for aerospace pyrometry compliance, for this specific application”.  The furnaces had to be “heavy duty” for rugged daily use in a commercial heat treating facility.  Another challenging aspect was the ability to heat rapidly but also to cool just as fast, without damage to interior metal as a load heat treated at 1000°F could be quickly followed by the next at 300°F.  The result is that the new DELTA H furnaces can heat and cool in a fraction of the time of the previous systems.  

ATP independently demonstrated both systems as capable of passing Class 1 uniformity (+/-5°F), throughout the operating temperature range, but qualified them as Class 2 (+/- 10°F) from 300°F to 1200°F.  Both are set up with Instrumentation Type B and feature 2 load thermocouples.     

The furnaces feature a guaranteed certified TUS volume of 2 feet wide, 1.5 feet high and 2 feet deep with a maximum continuous operating temperature of 1,200°F.  Both are designed to receive baskets of parts from many nearby heat treating operations for secondary heat treatments.  Temperature control and data acquisition are provided by Super Systems and feature the SSi 9130 controller / programmer.  Both furnace systems were quickly integrated into their Super Data facility monitoring system – with zero learning curve.

The SCAHT®-HD Series is available in a variety of sized with current models featuring a guaranteed TUS volume up 2’ x 2’ x 4’.  All models feature the high performance characteristics and attention to detail that have distinguished DELTA H® for compliance to strict aerospace and Nadcap standards.  

“We were looking for a partner to replace existing tempering furnaces that had become too costly to maintain and could no longer meet required pyrometry standards. Our goal was to install reliable and modern furnaces that were specialized for our small batch/job shop work.  DELTA H delivered exactly that as well as outstanding technical and service support.  When it’s time to sunset the remaining tempering furnaces in that department, DELTA H will be our first call.”

“I love family owned and operated manufacturing facilitates; DELTA H and Winston Heat Treating are 2 great examples. I am pleased to watch David Reger take over the family business (which started by David’s Grandmother and additional family members, back in the day, 3 generations ago, as a machine shop).  How excited was I to take over this account.  When I met David’s Father, John Reger, a few years ago, he told me I had to brand myself.  I was selling Nitriders at the time and he suggested I use the name “Plasma Princess”.  He will forever hold a special place in my heart!  When I started working for DELTA H® I was pleased to let WHT know we build furnaces for demanding aerospace heat-treating applications.  The process here was a challenge, but our CTO Richard Conway answered the call with a truly innovative furnace design. The performance and results speak for themselves and it is an honor to be of service to Winston Heat Treating.”
