In the world of metal recycling and processing, few pieces of equipment are as critical as the medium frequency furnace. These workhorses of industry play a pivotal role in transforming scrap metal, lead acid battery components, and other materials into reusable resources—supporting the circular economy and helping businesses meet their sustainability goals. Whether you're running a lead acid battery recycling plant, a metal fabrication shop, or a waste management facility, the right medium frequency furnace can mean the difference between operational efficiency and costly downtime, between meeting regulations and falling short.
But with so many options on the market, how do you choose? In 2025, the landscape is more competitive than ever, with manufacturers pushing the boundaries of power efficiency, safety, and integration with modern pollution control systems. This article breaks down the top 10 medium frequency furnaces available in the United States this year, highlighting their unique features, real-world applications, and why they stand out in a crowded field. From compact models ideal for small-scale operations to industrial giants handling tons of material daily, we've got you covered.
ProMelt MF-1200
Supplier: EcoRecycle Technologies
A powerhouse designed for heavy-duty metal melting, the ProMelt MF-1200 has quickly become a favorite among large-scale recycling facilities. Its 1200kW power rating and 2000kg/hour melting capacity make it a beast for processing everything from scrap steel to lead acid battery paste—key for operations looking to scale up without sacrificing speed.
1200kW medium frequency induction system for rapid heating
Smart temperature control with ±1℃ precision
Integrated air pollution control system compatibility
Automatic tilting mechanism for safe, efficient pouring
Ideal Applications:
Lead acid battery recycling plants, metal foundries, scrap metal processing yards. Its ability to handle lead paste reduction makes it a top choice for facilities focused on lead acid battery recycling equipment integration.
Why It Stands Out: Its energy efficiency rating of 92%—far above the industry average—translates to lower utility bills, while the built-in safety interlocks (overheat protection, emergency stop) give operators peace of mind.
EcoMelt MF-800
Supplier: GreenTech Solutions
For mid-sized operations that prioritize sustainability, the EcoMelt MF-800 is a game-changer. This 800kW furnace balances power and planet, with a design focused on reducing energy waste and minimizing emissions—perfect for businesses aiming to meet strict standards.
800kW induction system with variable frequency control
Low harmonic distortion (THD < 5%) for grid-friendly operation
Compact footprint (3.5m x 4m) ideal for tight facility layouts
Remote monitoring via mobile app for 24/7 operation oversight
Ideal Applications:
Small to medium lead acid battery recycling plants, automotive scrap yards, and metal recycling centers. Its compatibility with wet process equipment also makes it versatile for mixed-material processing.
Why It Stands Out: GreenTech's patented "EcoMode" reduces power consumption by 15% during idle times, and its quiet operation (under 85dB) makes it a hit with workers tired of noisy machinery.
MegaMelt MF-1500
Supplier: IndustrialRecyclers Inc.
When it comes to raw power, the MegaMelt MF-1500 doesn't mess around. With a 1500kW induction coil and 2500kg/hour capacity, it's built for facilities that process massive volumes of metal daily—think large-scale lead acid battery recycling plants or industrial foundries handling bulk orders.
1500kW high-frequency induction for ultra-fast melting
Heavy-duty refractory lining (12-month average lifespan)
Dual-cooling system (water + air) for non-stop operation
Load monitoring sensors to prevent overloading
Ideal Applications:
Lead acid battery breaking and separation system, metal melting furnace equipment for construction materials, and large scrap metal yards. It's particularly effective for processing lead paste from broken batteries, a critical step in lead acid battery recycling.
Why It Stands Out: Its rugged construction—including a reinforced steel frame and heat-resistant control panel—means it can handle 24/7 operation, a must for businesses where downtime equals lost revenue.
CompactPro MF-500
Supplier: MiniCycle Systems
Not all operations need a giant furnace, and the CompactPro MF-500 proves that small can still be mighty. This 500kW model is designed for workshops and small recycling facilities, with a space-saving design that fits into tight corners without skimping on performance.
500kW medium frequency induction for 500-800kg/hour melting
Plug-and-play installation (no specialized electrical needed)
User-friendly touchscreen interface with pre-set melting programs
Lightweight tilting (manual or electric options) for easy operation
Ideal Applications:
Small-scale lead acid battery recycling, jewelry making, and local scrap metal shops. Its portability (it can be moved with a forklift) makes it great for businesses that need flexibility.
Why It Stands Out: At just $85,000, it's one of the most affordable industrial-grade medium frequency furnaces on the market, making it accessible for startups or small businesses ready to upgrade from traditional melting methods.
CleanBurn MF-1000
Supplier: PureAir Technologies
As regulations around air pollution tighten, the CleanBurn MF-1000 is leading the charge in eco-friendly melting. This furnace comes with a built-in air pollution control system, including a high-efficiency dust collector and fume scrubber, ensuring emissions stay well below EPA limits.

Real-time emissions monitoring dashboard
Stainless steel construction for corrosion resistance
Ideal Applications:
Lead acid battery recycling plants in strict zones, lithium battery recycling facilities, and urban metal processing centers. It's a top pick for operations prioritizing air pollution control system equipment compliance.
Why It Stands Out: Unlike competitors that require separate pollution control add-ons, the CleanBurn MF-1000 is a one-stop solution—saving space, time, and money on installation and maintenance.
SpeedMelt MF-850
Supplier: RapidCycle Industries
For operations where time is money, the SpeedMelt MF-850 delivers. This furnace's claim to fame is its 30% faster heating time compared to standard models, thanks to a proprietary coil design that maximizes energy transfer to the metal load.
850kW high-efficiency induction coil
Pre-heat chamber for cold scrap metal (cuts melting time by 15%)
Quick-change refractory lining (reduces maintenance downtime)
Automated material feeding system compatibility
Ideal Applications:
High-volume scrap cable recycling, lead acid battery paste melting, and metal casting operations where throughput is king. Its speed makes it a favorite for facilities with tight production schedules.
Why It Stands Out: In a side-by-side test with a standard 800kW furnace, the SpeedMelt MF-850 processed 5 tons of scrap lead in 2.5 hours—nearly an hour faster. For businesses processing hundreds of tons weekly, that time savings adds up.
SafeHeat MF-900
Supplier: SecureRecycle Systems
Safety first—that's the motto of the SafeHeat MF-900. This furnace is packed with features designed to protect operators, from thermal imaging cameras that detect hotspots to a redundant cooling system that prevents overheating, even if one pump fails.
