Top 10 Medium Frequency Electric Furnace Suppliers in Germany in 2025

Founded in 1985 in the industrial hub of Berlin, EcoMetallurgy GmbH has built a reputation as a pioneer in sustainable metal melting solutions. What started as a small workshop focused on traditional furnaces has evolved into a global leader, with a particular emphasis on medium frequency electric furnace equipment tailored for recycling applications. Walk through their state-of-the-art facility today, and you'll find engineers collaborating on designs that prioritize energy efficiency and low emissions—two factors that have made them a favorite among lead acid battery recycling operations across Europe.

EcoMetallurgy's flagship product, the ECO-MF 5000, is a medium frequency electric furnace built specifically for metal melting furnace equipment needs in recycling. With a capacity ranging from 500 kg to 5 tons per batch, it's versatile enough to handle everything from scrap steel to the lead grids recovered from old car batteries. What sets it apart? The furnace's smart control system, which adjusts power input in real time to minimize energy waste. "We've had clients in the lead acid battery recycling sector report up to 25% lower electricity bills after switching to the ECO-MF 5000," says Karl Heinz, the company's sales director. "That's a game-changer for businesses operating on tight margins."

Beyond their technical prowess, EcoMetallurgy prides itself on partnerships. They often work hand-in-hand with recycling plants to design custom furnace setups, integrating seamlessly with existing equipment like crushers and separators. For a recent project in Bavaria, they retrofitted a client's lead acid battery recycling line with an ECO-MF 3000, reducing melting time by 40% and improving lead purity from 98% to 99.9%. It's this attention to real-world needs that has solidified their spot at the top of our list.

Munich-based TechFurnace Solutions may be younger than some of its competitors—founded in 1992—but it has quickly made a name for itself by prioritizing innovation over tradition. From day one, the company's mission has been to reimagine what medium frequency electric furnaces can do, and their latest line, the TechPro MF Series, is a testament to that vision. Designed with modularity in mind, these furnaces are built to grow with your business, making them ideal for small to medium-sized enterprises (SMEs) that don't want to overinvest in equipment they might outgrow.

Take the TechPro MF 2000, for example. With a base capacity of 1 ton per batch, it can be upgraded to 3 tons with the addition of a simple power module—a feature that has made it popular among metal fabricators and recycling startups. "We recognized that SMEs need flexibility," explains Lena Schmidt, TechFurnace's product development lead. "A company might start melting 500 kg of scrap metal a day and scale up to 2 tons within a year. Our furnaces adapt, so they don't have to buy a whole new system." This focus on adaptability extends to recycling, too. The TechPro MF 2000 is often paired with lead acid battery recycling equipment, where its quick heating cycles (reaching 1,600°C in under 30 minutes) ensure that recyclers can process more batteries in less time.

TechFurnace also stands out for its commitment to customer education. Their "Melting Masterclass" workshops, held quarterly in Munich, teach operators how to optimize furnace performance for different metals—from aluminum to lead—ensuring that clients get the most out of their investment. It's this combination of innovation and support that has helped TechFurnace earn a 95% customer retention rate, a statistic they're quick to attribute to their "partner-first" philosophy.

If there's one supplier that eats, sleeps, and breathes recycling, it's RecyclingTech Industries. Founded in 2001 in Hamburg, this company doesn't just sell medium frequency electric furnaces—they sell complete recycling ecosystems, with their furnaces acting as the central hub. For businesses in the lead acid battery recycling sector, this holistic approach is a major draw. Imagine a single supplier that can provide not just the furnace to melt lead, but also the conveyors to transport scrap batteries, the separators to extract lead grids, and the air pollution control systems to keep emissions in check. That's the RecyclingTech promise.

Their star product, the RT-MF RecyclePro, is a medium frequency electric furnace designed from the ground up for lead acid battery recycling equipment integration. It features a specialized lining resistant to the corrosive byproducts of battery melting, extending its lifespan by up to 50% compared to standard furnaces. "We don't just think about melting metal—we think about the entire process," says Jan Werner, RecyclingTech's CEO. "A furnace that works perfectly on its own but clashes with your separator or conveyor system is useless. Our RecyclePro line is engineered to play well with others."

Case in point: A recycling plant in Düsseldorf recently invested in RecyclingTech's complete lead acid battery recycling line, including the RT-MF RecyclePro 4000 furnace. Within six months, they reported a 30% increase in lead recovery rates and a 15% ｄｒｏｐ in maintenance costs. "The furnace communicates with the separator," Werner explains. "If the separator detects more lead grid material is coming in, the furnace automatically adjusts its power to handle the load. It's like having a team of experts working in sync, without the human error."

When it comes to precision, few can match Stuttgart's PrecisionMelters GmbH. Founded in 1978, this family-owned business has built its legacy on one core principle: "If you can't measure it, you can't improve it." That mindset is evident in every medium frequency electric furnace they produce, which comes equipped with some of the most advanced temperature and composition monitoring tools on the market. For industries where metal purity is non-negotiable—like aerospace or medical device manufacturing—PrecisionMelters is often the first name that comes to mind.

Their flagship furnace, the PM-Pro 3000, is a marvel of engineering. It uses a combination of infrared sensors and AI-powered software to monitor metal temperature and composition in real time, ensuring deviations as small as 0.5°C are corrected instantly. "In medical device manufacturing, even a tiny impurity can render a batch of surgical tools useless," says Heidi Müller, PrecisionMelters' quality control manager. "Our clients trust us because we guarantee consistency. The PM-Pro 3000 doesn't just melt metal—it refines it to perfection."

But don't let their focus on precision fool you: PrecisionMelters also caters to the recycling sector, particularly businesses that need high-purity metal output. Their PM-Recycle line, launched in 2020, is a medium frequency electric furnace optimized for lead acid battery recycling, where purity is critical for reusing lead in new batteries. "Recycled lead needs to meet the same standards as virgin lead," Müller notes. "Our PM-Recycle furnace uses the same precision monitoring as our aerospace models, ensuring that the lead we produce is clean enough for automotive batteries, medical equipment, or whatever our clients need."

Cologne-based GreenForge Technologies is proof that sustainability and profitability can go hand in hand. Founded in 2010—making it the youngest supplier on our list—GreenForge set out to disrupt the medium frequency electric furnace market by putting the environment at the center of every design decision. Their tagline, "Melting Metal, Not the Planet," isn't just a marketing gimmick; it's a promise backed by engineering.

Their most popular model, the Green-MF 4000, is a medium frequency electric furnace that uses 35% less energy than the industry average, thanks to a patented magnetic core design that reduces power loss during operation. But it doesn't stop there: the furnace also captures and recycles waste heat, using it to preheat scrap metal before it enters the melting chamber. "Why let all that heat go to waste?" asks Tobias Lange, GreenForge's founder. "A typical furnace loses about 40% of its energy as heat through the walls. We've turned that loss into a gain by redirecting it to warm up the scrap. It's simple physics, but it makes a huge difference for both the planet and our clients' bottom lines."

GreenForge has also made waves in the lead acid battery recycling sector with their Green-Recycle package, which pairs the Green-MF furnace with an air pollution control system designed to filter out lead particulates and sulfur dioxide—common byproducts of battery melting. "Recycling is supposed to be good for the environment, but if your process pollutes more than it helps, what's the point?" Lange says. "Our air pollution control system removes 99.7% of harmful emissions, making lead acid battery recycling not just profitable, but truly sustainable."

Dusseldorf's IndusFurnace Systems has been a stalwart in the heavy-duty furnace market since 1995, specializing in medium frequency electric furnaces built for large-scale industrial operations. If you need to melt 10 tons of scrap metal in a single batch, IndusFurnace is the supplier to call. Their IF-Mega series is designed for brute force without sacrificing efficiency, making them a top choice for steel mills, shipyards, and large recycling facilities that process everything from old cars to industrial machinery.

The IF-Mega 10000, their largest model, can handle up to 10 tons per batch and operates continuously for 24 hours, with minimal downtime for maintenance. "We built this furnace for clients who can't afford to stop production," says Markus Weber, IndusFurnace's operations manager. "A steel mill might need to melt 100 tons of scrap a day to keep up with orders. The IF-Mega 10000 is built to run around the clock, with components rated for 10,000 hours of operation before needing replacement."

While IndusFurnace is best known for their mega-sized furnaces, they've also made inroads into the recycling sector, particularly with lead acid battery recycling equipment for large-scale plants. Their IF-Recycle 5000, a 5-ton capacity furnace, is built to handle the high-volume demands of recycling facilities processing thousands of batteries daily. "Lead acid battery recycling is a numbers game," Weber explains. "The more batteries you can process, the more profitable you are. Our IF-Recycle 5000 is all about throughput—melting quickly, reliably, and in large batches."

Frankfurt's MetallCraft Engineers has been around since 1980, and in that time, they've learned one key lesson: every client is different. That's why the company has built its reputation on custom solutions, working closely with businesses to design medium frequency electric furnaces that fit their unique needs—whether that's a compact furnace for a workshop in Berlin or a specialized system for a lead acid battery recycling plant in Hamburg.

Take their recent project with a small-scale battery recycler in Leipzig. The client had limited floor space but needed a furnace that could handle 300 kg batches of lead grids. MetallCraft responded by designing a vertical medium frequency electric furnace, the MC-Vertical 300, which stands just 2 meters tall and fits through a standard factory door. "Most furnaces are horizontal, but we realized vertical designs save space," says Otto Berger, MetallCraft's lead designer. "The MC-Vertical 300 has the same capacity as a horizontal furnace half its size. It's a game-changer for small facilities."

MetallCraft's custom approach extends to materials, too. For a client in the chemical industry that needed to melt corrosive metals, they developed a furnace lined with zirconium oxide, a material resistant to acids and alkalis. "We don't just sell off-the-shelf products," Berger says. "We listen to our clients' problems and build solutions. That's why 80% of our business comes from repeat customers."

Leipzig's FutureMelters AG, founded in 2005, is all about looking ahead. Their team of engineers and data scientists spends as much time analyzing industry trends as they do designing furnaces, and it shows in their product lineup. FutureMelters is leading the charge in "smart furnaces," integrating IoT, machine learning, and cloud connectivity to create medium frequency electric furnaces that not only melt metal but also learn from their operations to get better over time.

Their latest innovation, the Future-MF Smart, is a furnace that uses sensors to collect data on everything from energy usage to metal purity, then sends that data to the cloud for analysis. Over time, the furnace's AI algorithm identifies patterns—like which power settings work best for lead vs. aluminum—and adjusts automatically. "It's like having a furnace that gets smarter the longer you use it," says Sophia Kuhn, FutureMelters' data scientist. "A new furnace might take a few weeks to optimize for your specific scrap metal mix. The Future-MF Smart starts optimizing on day one and keeps improving."

For lead acid battery recyclers, this smart technology is a boon. The furnace can detect variations in lead grid thickness or contamination levels in scrap batteries and adjust its melting time and temperature accordingly, ensuring consistent purity without manual intervention. "Recycled scrap is never uniform," Kuhn explains. "One batch of lead grids might be thicker, another might have more plastic residue. The Future-MF Smart adapts, so you don't have to. Our clients report a 40% reduction in manual adjustments after switching to smart furnaces."

Bremen's SustainableHeat GmbH, founded in 2015, is on a mission to decarbonize metal melting. While most medium frequency electric furnaces rely on grid electricity—much of which still comes from fossil fuels—SustainableHeat has pioneered furnaces that integrate with renewable energy sources, like solar and wind. Their "Solar-MF" furnace, launched in 2022, is the first medium frequency electric furnace designed to run entirely on solar power, making it a hit with eco-conscious manufacturers and recyclers.

The Solar-MF furnace works by storing excess solar energy in batteries during the day, then using that energy to melt metal at night or on cloudy days. "Germany has some of the best solar resources in Europe, but they're intermittent," says Ingrid Neumann, SustainableHeat's renewable energy specialist. "Our battery storage system ensures the furnace runs 24/7, even when the sun isn't shining. It's a closed-loop system: solar panels power the furnace, the furnace melts recycled metal, and the recycled metal is used to make new products—all with zero carbon emissions."

SustainableHeat has also partnered with lead acid battery recycling plants to create "solar recycling hubs," where the entire recycling process—from battery breaking to metal melting—is powered by renewable energy. "Lead acid battery recycling is a high-energy process, so switching to solar has a massive environmental impact," Neumann notes. "One of our clients in Bremen estimates they'll reduce their carbon footprint by 80% over five years by using our Solar-MF furnace and solar array."

Rounding out our list is Hannover's AllRound Furnace Co., a family-owned business founded in 1990 with a simple philosophy: "Do one thing and do it well." For AllRound, that "one thing" is building medium frequency electric furnaces that are reliable, easy to maintain, and affordable—qualities that have made them a staple in workshops, small factories, and recycling centers across Germany.

AllRound's bestseller, the AR-MF 1000, is a no-frills furnace with a 1-ton capacity, designed for businesses that need a workhorse without the bells and whistles. "Not every client needs AI or solar power," says Heinrich Schmidt, AllRound's owner and founder. "Sometimes, you just need a furnace that turns on when you press the button, melts metal quickly, and doesn't break down. That's what the AR-MF 1000 is all about."

Despite its simplicity, the AR-MF 1000 is surprisingly versatile. It can melt everything from steel to lead, making it popular among small lead acid battery recyclers who process multiple types of scrap. "We have a client in Hannover who uses the AR-MF 1000 to melt lead from batteries in the morning and aluminum from old window frames in the afternoon," Schmidt says. "It's not specialized, but it's reliable—and that's what small businesses need most."
