A virtual safety standards and codes seminar for industrial thermal processing is set for April 14-16. Presented by the Industrial Heating Equipment Association, the online seminar builds on the experiences IHEA developed while offering virtual courses last fall.

The online seminar will review the 2019 edition of the NFPA 86 Standard for Ovens and Furnaces, highlighting key changes and requirements. The seminar is intended for individuals involved in the design, manufacture, service or operation of industrial ovens, furnaces, kilns, dryers or thermal oxidizers. Understanding the proper use of national standards governing the compliant design and operation of ovens and furnaces is essential for everyone involved with this type of equipment, IHEA notes.

The three-day course will include the following sessions, all of which are presented by industry safety experts:

  • An overview of NFPA 86, including administration, references and definitions (Kevin Carlisle, Karl Dungs).
  • General requirements, location and construction (Glen Mortensen, Zurich Services Corp.).
  • Furnace heating systems, including Class B Furnace considerations (Bryan Baesel, Honeywell Combustion Safety).
  • Safety equipment and application, including safety shutoff valves (Aaron Zoeller, SCC Inc.).
  • Safety equipment and application, including programmable logic controller systems (Bryan Baesel, Honeywell Combustion Safety).
  • Class A ovens, furnaces and thermal oxidizers (Jason Safarz, Karl Dungs).
  • Safety equipment and application with safety controls and devices (Michael San Antonio, Fireye).
  • Special atmospheres for Class C ovens and furnaces and quench and molten salt bath (Anthony Cherol, Surface Combustion).
  • Commissioning, operations, maintenance, inspection and testing (Aaron Zoeller, SCC Inc.).

“While we are hoping to hold our seminars in person during the fall 2021,” said Anne Goyer, IHEA executive vice president, “there is ongoing demand for virtual training now. So, a decision was made to offer our popular safety standards and codes seminar [virtually] this spring.”

The registration fee is $295 for IHEA members and $350 for nonmembers. Registration includes a printed copy of the NFPA 86 standard and a certificate of completion awarding PDHs. Visit www.ihea.org/event/SafetySpring21 for additional details or to register.

Ovens and Furnace Maker Celebrates 50th Anniversary

Ovens and furnaces manufacturer Thermcraft Inc. is celebrating its 50th anniversary in 2021.

Thermcraft was founded in January of 1971, in a small warehouse space in downtown Winston-Salem, N.C., by Morris L. Crafton and Clara Martin Crafton. The company was later led by the late Thomas M. Crafton, their son, who served as president and CEO until 2020.

From that small startup operation, Thermcraft expanded to offer a range of thermal processing equipment, including industrial and laboratory furnaces, ovens, high temperature heating elements, insulation and replacement parts. The company currently operates out of a 70,000 ft² manufacturing and office space a few miles from its original offices.

The ovens and furnaces have been shipped to Air Force bases throughout the United States and will be used to support airplane and helicopter repair and maintenance. They will process a range of materials such as aluminum and tool steels.

All models are built to comply with AMS 2750 Class 2 (±10°F) and Class 5 (±25°F) specifications with instrumentation package D, which includes digital paperless recorder/controllers, high limit safety systems and SCR power supplies. Built-in TUS and SAT access ports support ongoing system-accuracy tests and compliance with temperature-uniformity survey requirements. Lucifer completed all wiring and surveyed temperature uniformity in-house prior to shipment.

Metal Can Manufacturer Installs Oxidizer to Abate VOCs


A Midwest-based metal-can manufacturer will utilize a recently installed regenerative thermal oxidizer (RTO) for the abatement of volatile organic compounds (VOCs).

The 6,000-scfm oxidizer, manufactured and supplied by Catalytic Products International (CPI), Lake Zurich, Ill., will control the emissions from two metal-lining machines and associated vertical dryers at the facility. It was designed to control emissions from the existing lines and allow for future process additions. The RTO will destroy VOC emissions with greater than 98.5 percent destruction-rate efficiency and a thermal efficiency of 95 percent, allowing for minimal gas consumption and operating costs.

CPI delivered a skid-mounted, prepiped and prewired oxidizer with the media installed for siting on a customer-supplied concrete pad. The installation took place in two phases to allow the can manufacturer to construct a building to shelter the RTO and enclosed walkway. This approach ensured that the entire system was installed correctly, and the facility was online and producing product with minimal downtime.


Walk-in Oven Delivered Quickly for Vaccine Manufacturer

When a vaccine manufacturer ordered walk-in ovens for a drying application, ITW EAE Despatch was able to commit to a short lead time due to its streamlined production line.

The Despatch TFD3-10 walk-in ovens include horizontal recirculating airflow to ensure uniform temperatures. A high volume fan circulates air through perforated, aluminized steel walls to create a constant, horizontal airflow across all sections of the oven. The vaccine manufacturer’s application involves drying flammable solvents, which require Class A ovens designed to meet NFPA 86 requirements. The oven was supplied with a pressure-relief panel, purge timer and exhaust fan.


Industrial Coating Company Installs Curing Oven

An industrial coating company that serves a range of industries took delivery of a curing oven it will use for a process that requires even product heating.

The oven, which was built by Lewco Inc., has a maximum operating temperature of 800°F (427°C). It includes a top-mounted heater box with a 1 million BTU direct-fired natural-gas burner. A 17,000-cfm circulation fan delivers dual airflow throughout the workspace.

Lewco also designed two custom self-propelled load cars to carry a customer-supplied retort in and out of the oven. In addition to loading and unloading the retort, the cars will continuously rotate the retort 360 degrees or oscillate the retort 180 degrees in both directions. The parts tumble inside the retort to ensure an even coating.

The oven is equipped with pneumatically operated vertical-lift doors on each end. This allows the company to index the cars from both ends without any cool-down cycle, which increases its production capabilities.


Boilers Handle Steam, Heating Load at Medical Facility

Steam heating technology commonly used to provide process heating will supply comfort heating for a large medical facility in the Southern California desert. The facility purchased 13 boilers from Parker Boiler to handle the steam and heating load of a new expansion.
