Aerospace Heat Treatment & Industrial Furnaces

Aerospace Heat Treating Equipment

DELTA H manufactures heat treating equipment for the aerospace industry that meets and exceeds the strict and demanding requirements called for by AMS2750G and Nadcap accreditation when processing aluminum alloy, tool steel, titanium, PH stainless steel, and composites. Our heat treating furnaces & ovens guarantee times, temperatures, uniformity and are supported by unparalleled repeatability.

Purchasing one of our ovens allows your organization to bring the process in-house, which means no outsourced heat treating cost—and typically, most of our clients boast of an ROI of fewer than two years and doing so without impacting CAPEX funds. Your system will literally pay for itself.

At DELTA H, we pride our self on being the only furnace & oven manufacturer with a dedicated division, knowledge, and products to specifically meet the needs and demands of aerospace OEMs, MROs, Component Repair and Overhaul Facilities, and Aircraft Parts Manufacturers. We serve large corporations such as Lockheed Martin, Boeing, FedEx, Aviation Technical Services, Curtis Wright Controls, Honda Jet, branches of the United States Armed Forces as well as medium to small maintenance hangars and parts manufacturers. All rely upon DELTA H to solve their heat treat challenges and provide quality, value, and timeliness to keep their aircraft flying quickly. We have developed an impressive brand and reputation over the years and have “earned our wings” in aerospace heat treating.

Heat Treatment Ovens & Industrial Furnaces

DELTA H offers numerous types of industrial furnaces & heat treatment ovens for materials applications requiring walk-in ovens, bench top furnaces, cabinet style ovens, composite curing ovens, powder coating ovens and associated equipment all of which can be configured as a batch oven or a continuous system. A variety of models are available in-stock that are gas-fired or electric heated or we can custom design a system tailored to your specific size and heat treatment application.

Popular systems include our Walk-In Oven Series which is available as a “Turn Key” system with installation and training included or as an easy-to-install kit system. Multiple options are available for installation, warranty, and start-up on all models including remote and full on-site guided assembly. The DELTA H Walk-In Oven is ideal for a wide variety of industrial thermal processing/ heat treatment oven processes such as composite curing, powder coating, baking and drying as well as just about any other industrial application including new or emerging technologies. Do not hesitate to contact us with your specific application as we offer custom engineered and designed systems.

All of our ovens feature our exclusive and proprietary directional duct system which allows for total adjustment of airflow in order to optimize temperature uniformity. Our industrial furnaces & heat treatment ovens are relied upon by leading companies where strict compliance to standards as well as high performance and total reliability is required for continuous 24/7 operation.

Our Reviews

I have to say that our Delta H is a workhorse. We’ve increased our workload tenfold over the last 2 years and it has handled it like a champ. Best purchase I’ve ever made to be honest.

Chris RomeroChief Inspector at Aircraft Systems, Division of Com Jet (customer since 2013)

The oven has been up and running. Really appreciate Richard’s efforts. We have been really busy this month upgrading aircraft and the oven has been a huge time saver for us.

Dave TibbettsDirector of Shop Operations at Columbia Helicopters, INC. (after only a month in service)

The DELTA H oven is definitely top notch! It has done nothing but make our heat treating process so much easier and much more efficient so we can push out products to keep these planes in the air.

MSgt DelmoMcGuire Air Force Base

Our DELTA H Furnace has become the workhorse of our backshop. Best thing I've ever bought as an engineer.

Tom Ballas, EngineerTinker Air Force Base

The oven is working ‘super!’. So far all the parts we have done have passed both the hardness and conductivity tests. Thanks to all involved to help us get everything up and running. It saves about 2 days of down time every time we do a part since we can now do our own SAT's and TUS's. Additionally, since we have 2 chambers, there is virtually no downtime involved with waiting for the oven to cool for a tempering operation. If questions come up, I feel confident that it will be remedied in an expedient manner, based off the support we have received thus far. Thanks again.

MSgt HarrellMcGuire Air Force Base

I am very proud to know that, together, we are making the USAF structural maintenance and repair environment processes more robust, more reliable and in compliance with 21st century aerospace standards. Thank you for the confirmation that we are serving our fellow warfighters well! Keep up the good fight. I hope your team continues to provide excellent equipment and service to the USAF and other DOD aviation entities. Our warfighters deserve the very best.

The DELTA H furnace design, training and support services have no parallel in industry and are ideal for aircraft MRO facilities.

Naval Air Station Patuxent River

The very finest aviation heat treating equipment I've ever seen.

Russ Kota, Director of MaintenanceNorth State Aviation

For what a DELTA H Furnace brings to an MRO - it is priceless.

Erik Ortega, Director of MaintenanceFedEx LAX

Our DELTA H furnaces have been working great! We are very happy with them!

Mario Saade, Operations Chief at AeromanTaca Airlines

DELTA H’s knowledge of aluminum heat treating processes allowed us to acquire an oven that was capable of meeting or exceeding all aerospace pyrometry specifications at a low cost with solid training, technical, and warranty support.

Jeff Bonner, PresidentJeff Bonner R&D

Just wanted to let you know that I would recommend your ovens anytime.

Heat Treating ManagerVT San Antonio Aerospace

At 150 F [our DELTA H Composite Oven] is within 3 tenths of a degree, and at 250 and 300 degrees Fahrenheit it's within 1.5 degrees anywhere in the oven chamber. The guy who did the calibration was even impressed. It runs like a Swiss Watch!
