Providing Thermal Processing Equipment, Engineering and Service Solutions Since 1990

Aerospace Systems

DELTA H manufactures AMS275E and Nadcap Certified Aerospace Systems for Aluminum, Tool Steel, Titanium and PH Stainless Steel are designed to meet or exceed all of your heat treating requirements. Our Industrial heat treating furnaces & ovens guarantee times, temperatures, uniformity and are supported by repeatable performance as required by the aviation industry. We design our leading-edge automated heat treating equipment in-house utilizing programmable Recorders, Logic Controllers (PLC’s), and microprocessor-based stand-alone loop controllers that are designed specifically for Industrial Furnace & Oven metallurgical processing. This synchronizes the flow of inputs, sensors, and contacts from various field devices to specific outputs, valves, flow meters, motors, and contacts. In other words: expensive manual labor and the use of index cards are becoming archaic in this industry.

With automation, the coordination of inputs and outputs leads to precisely-timed actions that permit tight control of even the most stringent processing applications-

Composite &
Industrial Systems

DELTA H offers numerous industrial thermal processing solution ovens for materials applications including walk-in ovens, bench top, cabinet style, paint curing, powder coating and associated equipment, including washers, box, and conveyor ovens all of which can be configured as a batch or continuous system. A variety of models are available in-stock or we can custom design a system tailored to your specific heat treat application.

Our popular Walk-In Oven Series is available as a “Turn Key” system with installation and training included or as an easy-to-install disassembled kit system. Multiple options are available for installation and start-up on all models including remote and full on-site guided assembly. The DELTA H Walk-In Series Ovens are ideal for a wide variety of industrial applications such as composites, powder coating curing, baking, drying, and other limitless industrial thermal processing applications. All of our ovens feature our exclusive and proprietary “DELTA “H” air duct system which allows for total adjustment of airflow in order to optimize temperature uniformity. DELTA H Industrial Ovens are relied upon by leading companies where strict compliance to standards as well as high performance and total reliability is required.

Consulting Services

Considering a new furnace or oven and don’t know where to start? Perhaps you have a system already in place and simply need maintenance or you are in the market for an entirely new system. Our in-house combustion genius, Richard Conway, who possesses 23+ years of experience in the industrial furnace, oven, kiln, and thermal processing industry can help. Richard will perform a time-tested methodical engineering analysis to determine the root cause of any current bottlenecks in your process and work with you to modify your process resulting in improved performance, operation and reduce expenses. When it is time to upgrade to a new furnace or oven, Richard will personally engineer your new system and our design team will bring your vision to life.

If your company already has an idea of your heat treating needs, Ellen Conway, our president of sales and an industry expert can guide you through the quoting and purchasing process for your new industrial furnace or oven. Among other services provided in the quoting process, Ellen will work to provide you with the most viable and cost-effective new solution. Ellen will then provide you with a full technical quote including a cost breakdown and personally guide you through the process of purchasing your new furnace or oven.


I am very impressed with the quick response from [Ellen] & Richard. With the use of the Internet, I have done hundreds of inquiries through the years for equipment & supplies. In all of the years of using the Internet for research, I have never had a company respond so quickly & provide the detail you have in such a timely manner. You have a great website, full of great information, especially for me since I am new to the process of Heat Treating Aluminum. I really appreciate all of the help & support you have given me so far.
