Deliveries are scheduled over the  next year to provide the USAF with cutting-edge heat-treating capabilities for aviation-grade  metals—ensuring…

Doha, Qatar — DELTA H® and Phillips Federal Division have commissioned a state-of-the-art Defender Series heat treating furnace at Al Udeid Air Base, providing the U.S. Air Force with mission-critical capability to heat treat all aviation-grade metals used in aircraft maintenance. The dual-chamber system features: A radiant heat lower chamber (1,000°F–2,000°F, 12”W x 12”H x 48”D TUS volume) with inert atmosphere A convection heat upper chamber (200°F–1,200°F, 18”W x 12”H x 48”D) capable of rapid cooling from 1,000°F to below 200°F in under 30 minutes, allowing solution heat treating and aging (T6) in the same chamber before part freezing is…

Carroll, Ohio: DELTA H® has surpassed over 50 heat treating system installations to multiple military facilities including Air National Guard bases, USAF bases stateside, Guam, Alaska, and Hawaii, Air Bases in Japan, Germany, United Kingdom – Royal Air Force, Middle East, the US Navy, US Coast Guard, and US Army facilities. The systems included either single, dual or triple chamber designs of both the heavy duty commercial aviation standard models DCAHT® / SCAHT® Series, DELTA H’s innovative Defender Series – developed for the armed forces, and aircraft composite walk-in ovens. All systems are in full compliance to NAVAIR Tech Order…

Joint Base San Antonio – Randolph, TX:  DELTA H® recently commissioned a dual chamber model DCAHT®-181248-1200/500-MIL, a DCAHT®-241672-1200/500-MIL, and a large single chamber SCAHT®-303048-1200-MIL.  The project is for supporting T-38 Talon Repair Inspection and Maintenance, or TRIM, modifications for performing localized, depot level maintenance to replace or repair key parts in order to keep these valuable training platforms mission ready. USAF depot level heat treating requires full compliance to AMS2750H.  The heat treating systems provided by DELTA H were for replacing existing systems which proved too troublesome or costly to try to qualify and were never designed for modern pyrometry…

Southern California: DELTA H® was recently recognized by a major military aircraft support facility for the excellent performance and reliability of a SUPER DCAHT® furnace system supplied 2018. The massive dual chamber furnace system features twin 30” wide, 16” high, and 120” long work volumes, with both being capable of operation from 250°F to 1,200°F as Class 2.  Both chambers feature the exclusive “AGING MODETM” venting system which enable not only low temperature operation, but also rapid cooling. Both chambers are capable of aluminum solution heat treating, annealing, and aging, as well as PH stainless aging and stress relieving. The…

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…

Elyria Ohio:  DELTA H® recently delivered twin furnace systems to RIDGID® TOOLS.  The challenging requirement was to heat parts from ambient to 975°F, soak for 2 hours, cool to 120°F as fast as possible, soak 2 hours, then repeat.  The solution was an innovative design featuring all stainless steel interior and low mass ceramic fiber insulation for minimal heat retention.  High powered electric heating elements, coupled with pneumatically operated blast gates and proprietary ductwork / venting enabled the system to accomplish the requirements with precise repeatability total reliability as a “cold to cold” heat treating operation.     The furnaces feature a…

DELTA H®  and Phillips Federal Deliver To Tinker AFB, OK - USAF, Their First AMS2750H Qualified Heat Treating System For Military Aircraft Oklahoma City – Tinker AFB:  DELTA H® recently delivered the first heat treating system certified to AMS2750H for heat treating aviation grade aluminum for military aircraft.  The new system is the second installation at the massive depot facility and placed side by side with the previous system installed in 2015.  Third party services for calibration and qualification were performed by Andrew Bassett of Aerospace Testing and Pyrometry and completed within one day on site. The certifications for instrumentation,…
