DELTA H® Develops Horizontal Air Quench System For Aluminum Heat Treating of Heat Exchangers

Carroll Ohio: DELTA H® has recently completed the build of a horizontal quench system for aluminum which features a high velocity air quench. The purpose of this system is to heat treat complex heat exchanger parts which are subject to distortion if quenched in water or sprayer. By subjecting the parts to an air quench in the range of 65 MPH air velocity, the parts are able to reach AQ condition and then achieve T4 temper after 96 hours. .

The furnace is a version of the DELTA H Defender Series, and has a certified TUS volume of 30”W x 30”H x 72”D and a maximum operating temperature of 1,200°F. A stainless tray is featured which allows for transferring the parts into the furnace, then out over the air quench station with optional automation. The furnace features “AGING MODE” and can be easily configured for artificial aging as well for 7075 at 250°F.

The system includes all features for full compliance to AMS2750G, and is capable of Class 1 uniformity, but certified to Class 2. Honeywell DCP250 controller and Honeywell MiniTrend recorder with TrendServer Pro and AMS2750 Process Monitoring are included with full on site qualifying and operator / QC training. Multiple sets of thermocouples and SAT thermocouples are included for a 3 year supply.

“This project needed extreme air flow. The previous system at this facility was a drop bottom and relatively long quench delay, plus could only reach around 42 MPH air velocity. The DELTA H furnace increased the air velocity by approximately 1.5 times as well as reduced the quench delay time to approximately 7 seconds. This proved to be capable of having the parts reach AQ condition, followed by natural aging to T4 every time.

DELTA H® “SUPER DCAHT®” Recognized For 4 Years’ Service To Military Aircraft AOG Support Facility

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 furnace system features a quench tank which is over 12 feet long. The tank features a powered drive system, a heating system, auto-refill of water, a high temperature external water pump, and electronic sensors for quench delay recording.

The model DCAHT®-3016120-1200/1200-BAC has specific features for primary compliance to BAC5621, as well as now AMS2750G. The system provides tamperproof batch records, simplistic means of performing the temperature uniformity survey (TUS) as well as the system accuracy test (SAT). The control and data acquisition feature Honeywell instrumentation and customized software. All necessary compliance and operator training provided by DELTA H®.

“This furnace system is, by far, the easiest system to maintain and has virtually 100% reliability. We especially appreciate the rapid technical support when needed from DELTA H.”

Mike Lawrence, Director – Lawrence Technical Services Company, LLC
Maintainer of the Super DCAHT®

“The challenge with this project was to have both chambers be able to operate and qualify over the full range of the required temperatures for aviation grade aluminum heat treating. This is especially helpful with the long aging cycles relative to the solution heat treating cycles – either, or both chambers can be used for aging – which helps minimize bottlenecks. When it comes to support for an aircraft on ground (AOG), every minute is potentially costing thousands of dollars and this system has performed every time needed.”
