Dry Hearth Melting Furnaces
GM-D SeriesOur GM-D Series gas dry hearth melting furnace features a charging chamber that has no molten metal in it thus it reduces the dangers of metal splash and prevents temperature drop caused by the addition of cold ingots or scrap to the metal bath. The charging chamber is angled down and as the metal melts it runs into the metal bath. Like all our Dynamo furnaces, the GM-D Series is controlled by a PLC and a color HMI touch screen which runs a sophisticated program that optimizes performance, operation, and efficiency.
Safety and Efficiency.
The dry hearth charging chamber has no molten metal in it thus it reduces the dangers of metal splash. In addition, this design prevents temperature drop caused by the addition of cold ingots or scrap to the metal bath. The charging chamber is angled down and as the metal melts it runs into the metal bath. Less drop in temperature, means a more consistent temperature, which translates to better quality castings and less scrap.
Separate Melting and Holding Chambers.
Low end dry hearth furnaces have only one chamber. Our dry hearth furnace has two separate chambers with two burners, two air blowers, and two independent heating systems. Our two chamber dry hearth furnace produces substantially less oxides and drastically reduces temperature drops which result from charging the furnace. All this means a better quality melt and consistent temperature which are critical for high quality castings. Our dry hearth furnaces are ideal for melting ingots and remelting returns.
HIGHEST RETURN ON
We Give You More Furnace for Your Money.
To be competitive today’s economy requires that manufacturers run their operations more efficiently and cost effectively than ever before. We offer the highest ROI (return on investment) in the industry. Dynamo gives you high-quality products for a reasonable investment and with more features than any other company. Simply put, we give you the most for your money!
We Give You Options of PLC & HMI.
Select the control system that is best for you and easiest for your maintenance team.
Easy to Operate
Greater Control - Means Greater Efficiency.
The GM-E Series Mini stack 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.
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.
VFD DRIVE BLOWER
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.
Easy Access to the Entire Interior of the Furnace with no Dead Spots.
The key to long furnace service lifetime is regular cleaning. However, cleaning is hard through a small maintenance door. We have made our side cleanout door extra wide to facilitate and encourage easy, regular cleaning.
ALUMINUM DROSS FILTRATION
Comes Standard with All Models and Keeps Your Aluminum Clean.
Our ceramic foam filter can effectively remove and absorb large or small impurities in molten aluminum, improves the surface quality, and microstructure effectiveness. Thermal shock resistance, this ceramic filter improves purity and improves erosion resistance molten aluminum.
Simplfy and Speed Up Charging the Furnace.
Our standard door is a manual hinged. However, you can add this electric drive charging door to increase speed and productivity.
We Can Remotely Troubleshoot Your Furnace from Our Facility.
Our GM-D Series dry hearth melting furnace includes 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.
