ROUND CRUCIBLE MELTING FURNACES
GM-A SERIES
Our versatile GM-A Series is a traditional stationary round crucible furnace and is suitable for a wide variety of casting and melting applications. A unique feature is the heat recycler that is used during startup to increase efficiency. Economically priced, this furnace is easy to install and simple to run. Like all our furnaces, the GM-A Series is controlled by a PLC and a color HMI touch screen.

EASY TO OPERATE INTERFACE
Greater Control - Means Greater Efficiency.
Our GM-A Series melting furnaces feature state-of-the-art PLC control with large color HMI screens with easy-to-read graphics - all at no extra charge. See in real time all furnace functions and change any setting on the fly. Now that's control. Screen shown with optional upgraded Siemens control system.
VFD DRIVE BLOWER MOTORS
Better Efficiency and Lower Operating Cost.
Lots of air without control wastes a significant amount of energy. We use VFD Drives combined with Premium Inverter Duty Motors to give you greater RPM only when it is needed. All this translates into greater efficiency, lower operating costs, quieter operation, soft start and longer motor life. The advantage is clear. This is just one of the many ways we use to increase furnace efficiency, and reduce long term operating costs.
HIGH QUALITY COMPONENTS
We Use Brand Name Components You Know and Already Use.
We use only the finest quality components that are open source and readily available locally in your area, or from our online parts store.
REMOTE SERVICE
We Can Remotely Troubleshoot Your Furnace from Our Facility.
As an option, our GM-A Series crucible melting furnaces can include a Remote Connectivity Unit which allows our furnace technicians to remotely check the performance of the furnace, make any needed changes to the program or HMI, or to troubleshoot it directly from our service center. The customer is only required to connect the unit to the Internet via an Ethernet cable. We handle the rest.
