Whether it be our bodies or our favorite objects, we all know that if we want to keep anything working well for a long period of time, we need to keep up with routine maintenance. Not only will it keep everything intact, but it will also continue to work hard for you. When it comes to vacuum furnaces, the same thing holds true. Having a well-designed preventative maintenance program in place will ensure everything runs smoothly and protect your investment.

Upon purchase of the vacuum furnace, read the manual. It help with future troubleshooting, and also give you an indication of what regular maintenance will entail down the road. Obviously, cleaning, part replacement and lubrication is necessary, but also performing leak checking of the machine and repairs as needed. The more you know about your machine, the easier it will be to detect when things are beginning to go wrong. Keep good records – parts, maintenance checklists of all the components that makes the furnace run smoothly.

Here at GM Enterprises, we offer a wide array of services for our vacuum furnaces to our clients. Not only does our expertise involve training and technical support programs to help you learn your machine, but we also provide installation, repairs and replacement parts. Ask our parts and service department about our maintenance program for vacuum furnaces, spare parts, controller upgrades and other preventative services.

Investing in a vacuum furnace is a big investment, and one that needs to last for a long while. But everything needs a bit of tender loving care from time to time in order to continue to do its job. Taking the time to learn the ins and outs of it will make this investment one that will service you for years to come.

Dear Nitrex Community,

At Nitrex, the safety and well-being of our communities, employees, our customers, suppliers and stakeholders is always our priority. We recognize the important role we play in providing our Nitrex Heat Treating Solutions through our three divisions – Nitrex Turnkey Systems, Heat Treating Services, United Process Controls – including our new colleagues from G-M Enterprises, during this critical time. We are actively monitoring the COVID-19/Coronavirus situation and taking steps to help keep our communities safe. Herein, we share with you the steps we are taking.

Aligning with public health authorities

We have established a team dedicated to respond to this pandemic and have prepared Business Continuity Plans to ensure the continuation of products, services and customer support. We are closely monitoring updates regarding COVID-19 from global organizations such as the World Health Organization as well as various public authorities in each of the regions we operate. We continue to seek guidance from these agencies, public health officials and government agencies on an ongoing basis.

Protecting the Nitrex community

As our employees interact with customers, suppliers and the general public, we have taken steps to limit exposure to the virus. Strict restrictions were put in place on both international and domestic travel, limiting visitors inside our facilities, cancelling large-scale event attendance, reducing face-to-face meetings to a minimum, providing work-from-home solutions, and continue to reinforce safe behavior in every environment – from our industrial plants, sales offices to our administrative offices, we are promoting deep-cleaning and routine disinfection.

Assisting our employees

We are in daily communication with our employees reminding them about the importance of good hygiene, providing health education and support whenever needed. We encourage employees who feel ill to stay at home and we have specific quarantine and communication procedures in place should an employee be diagnosed with COVID-19 or is asked to self-isolate by public health authority. Moreover, Nitrex provides comprehensive benefit packages to support employees during this period.

Our commitment to our customers and our communities

Our dedicated team around the world remains fully committed to continue working and supporting our customers during this period of uncertainty.

When the time comes to purchase a new industrial furnace, there are several points that need to be considered beforehand. Like, the operating temperature that will be used most often. Because, despite what many may think, it isn’t “one size fits all”. The following are a few of the common things one should consider when preparing to purchase an industrial furnace:

Temperature ranges. It is important to know what temperature you will need for your typical project, in addition to future projects you may have.

Future considerations. Because you can’t always use one furnace for all of your projects, you may want to consider a larger unit with respect to issues of maintenance, reliability, and temperature uniformity as compared to a higher temperature unit.

Furnace geometry. The box unit is great for loading samples in a batch operation, while a tube unit is generally better for a continuous application.

Uniformity. Many options are available ranging from the introduction of cooled gases, to vents, fans, or a combination, to achieve a controlled cool-down cycle.

Controls. Will a standard single set point temperature controller work, or will a programmable unit be required? Making sure you know what you’re looking for will narrow in your options.

Atmosphere. Another consideration should be the atmosphere that will be used in the unit, as this can have a significant bearing on purchase and maintenance costs.

Customization. The final item to be considered – cosmetic issues. Standard products are available from most vendors of lab furnaces, while some manufacturers offer standard units as well as fully customized units that can be specified and engineered to exact customer requirements.

G-M Enterprises supplied a 20-bar vacuum furnace to Paulo Products Co. The furnace, which has an 8,000-pound load capacity and maximum work-zone dimensions of 48 inches wide x 36 inches high x 60 inches long, was installed at Paulo’s St. Louis, Mo., facility. The furnace is equipped with an 800-hp cooling motor, graphite hot zones and an Allen Bradley PLC control system. Thanks to this new furnace, Paulo-St. Louis can now handle larger parts requiring vacuum heat treatment. The facility has already successfully completed all necessary testing and has received approval as a provisional heat-treat source of Die Insert Material for Ford Motor Co. and General Motors, Powertrain Division.

G-M Enterprises (Corona, Calif.) shipped three vapor phase alumina (VPA) coating furnaces in 2006 and has received two orders for VPA coating furnaces to be delivered in February 2007. The orders are the result of increased demand in aircraft-engine construction, which requires vapor phase alumina coating of blades and vanes. G-M has developed a system where both sides of the furnace have a fully enclosed loading/unloading chamber with forced cooling.

These furnaces come equipped with G-M’s WONDERWARE computer control system for fully automatic operation in conjunction with mass-flow control panels.
