Tilting Reverberatory Melting Furnace

Reverb Melting Furnace

GM-J Series

Our GM-J Series aluminum gas reverberatory melting furnace, also known as a reverb furnace, is an excellent choice for large volume melting of scrap and ingots. This series features a hydraulic tilting system and is available with a single large melting chamber, or with a dual melting and holding chamber (recommended). This design can be adapted to your specific requirements. The innovative design offers ultra-high efficiency. Large, electric drive, charging doors allow for easy charging and cleanout access. Like all our Dynamo furnaces, the GM-J Series is controlled by a PLC and a large color HMI touch screen which runs a sophisticated program that optimizes performance, operation, and efficiency.

Smaller Footprint


This Furnace Takes Up Less Space.

Our multi-chamber design dramatically reduces the furnace foot print. By removing a wet bath charging well, and by adding more chambers we increase the melting to holding ratio to approximately 1:3 (even lower for non die casting applications). That means a substantial saving of valuable floor space in your facility and reduced operating cost.



Precise and Dependable Molten Metal Level Measurement.

Probe type molten metal level sensors can corrode and be affected by dross buildup, and in time they can give back false readings. Our laser level system is no contact, precise, dependable, and durable, and offers long term maintenance free operation.

High Thermal Efficiency


We Add Multiple Layers of Insulation.

The result is excellent efficiency which means a furnace which not only burns less gas, but is actually not dangerous to touch.



We Add Way More Insulation to Our Furnaces Than Most Manufacturers.

The result is even greater efficiency and a solid, sturdy construction which is hard to beat.



We Give You Options of PLC & HMI.

Select the control system that is best for you and easiest for your maintenance team.



Two are Better Than One.

Using double air blowers gives us more flexibility and precision in the amount of air available for the melting and holding chambers at any given time. When balanced correctly they increase the efficiency of the furnace and reduce running costs.



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.



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.



We Can Remotely Troubleshoot Your Furnace from Our Facility.

Our GM-J Series tilting reverberatory melting furnace 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.



Remotely Monitor Your Furnace Performance From Any Device.

As an option, all our furnaces are available with Industry 4.0 remote performance monitoring units which feature a custom dashboard. You can not only monitor furnace performance, but you can be notified before an issue occurs. Included are condition based maintenance reminders and shift performance statistics. Minimize impact of emergencies and maximize furnace uptime, and productivity. See what is going on with the furnace and your production from any device, anywhere in the world.
