Top 5 Refrigerant Recovery Machine Suppliers in South Korea [2025]

If there's a name that comes up again and again in Korean refrigerant recovery circles, it's Kyungseo Environmental Technologies. With over 25 years in the game, this Seoul-based company has built a reputation for reliability that's hard to beat. What really sets them apart? Their focus on refrigerant extraction machine l refrigerant recycling machine sd-680 , a workhorse model that's become a staple in repair shops and small to mid-sized recycling centers across the country.

The SD-680 isn't just another machine—it's designed with the user in mind. We talked to Ji-hoon, a technician at a busy Seoul HVAC service, who raved about its portability: "I used to struggle with bulky recovery units that were a hassle to move between job sites. The SD-680 is lightweight, fits in my van easily, and still has the power to handle most residential and commercial units. Plus, the digital display makes it simple to track recovery progress—no more guesswork."

But Kyungseo doesn't stop at portable units. They also offer industrial-grade systems for large facilities, including integrated solutions that pair refrigerant recovery with refrigerator recycling equipment . For example, their turnkey refrigerator recycling lines include conveyors, shredders, and the SD-680 as a key component, ensuring that refrigerants are safely extracted before appliances are dismantled. This all-in-one approach has made them a favorite among companies looking to streamline their recycling processes.

What customers love most, though, is their after-sales support. "We had a minor issue with an SD-680 last winter, and Kyungseo's service team was at our shop within 24 hours," said Min-jun, operations manager at a recycling plant in Incheon. "They didn't just fix the problem—they walked us through maintenance tips to prevent it from happening again. That kind of care goes a long way."

With a commitment to sustainability (they offset 100% of their manufacturing emissions) and a product line that balances power and practicality, Kyungseo is a top choice for anyone serious about refrigerant recovery.

For those in need of heavy-duty performance, Hankook Eco Solutions is the go-to. Based in Busan, this company specializes in high-capacity recovery systems that can handle the most demanding industrial applications. Their star product? The refrigerant recycling machine rrm-650 , a beast of a unit designed for large-scale operations like chemical plants, data centers, and commercial refrigeration warehouses.

The RRM-650 isn't messing around. With a recovery rate of up to 15kg per hour and the ability to handle mixed refrigerants, it's built for speed and efficiency. "We process hundreds of old walk-in freezers every month at our recycling facility," explained Soo-jin, plant manager at a Busan-based waste management company. "Before we switched to the RRM-650, we were using three smaller units, and it was always a bottleneck. Now, one machine handles the workload, and we've cut our recovery time by almost 40%. That's a game-changer for our productivity."

But Hankook doesn't just focus on power—they're also pioneers in smart technology. The RRM-650 comes equipped with IoT connectivity, allowing operators to monitor performance, track refrigerant types, and even schedule maintenance alerts from a smartphone or computer. "I can check in on the machine from my desk, see how much refrigerant it's recovered today, and get notified if there's a pressure ｄｒｏｐ or temperature issue," Soo-jin added. "It's like having a 24/7 assistant watching over things."

Another standout feature? Their commitment to compliance. South Korea's environmental regulations are some of the strictest in Asia, and Hankook's machines are certified to meet all current and upcoming standards, including the K-eco mark for energy efficiency. This peace of mind is invaluable for companies looking to avoid fines and stay on the right side of the law.

While their industrial focus means they're not the best fit for small-scale users, Hankook Eco Solutions is unbeatable for businesses that need to move a lot of refrigerant quickly and reliably.

If innovation is your priority, GreenTech Innovations Korea should be on your radar. This relatively new player (founded in 2015) has quickly made a name for itself by pushing the boundaries of what refrigerant recovery machines can do. Their claim to fame? The EcoVortex series, which uses advanced vortex technology to recover refrigerants more efficiently than traditional methods—up to 30% faster, according to their tests.

But GreenTech isn't just about speed. They're also leading the charge in sustainability. Their machines are built with recycled materials where possible, and they offer a take-back program for old units, ensuring they're properly recycled instead of ending up in landfills. "We wanted to create a product that's good for the environment at every stage," said Young-mi, GreenTech's head of product development. "That means not only recovering refrigerants but also making sure the machines themselves have a minimal footprint."

One of their most popular models is the EcoVortex Mini, a compact unit designed for mobile technicians. It's not quite as powerful as Kyungseo's SD-680, but it makes up for it in energy efficiency—using up to 20% less electricity than comparable models. "As someone who's conscious about my carbon footprint, using the EcoVortex Mini feels like I'm doing my part," said Hyun-woo, a freelance HVAC technician. "And since it's energy-efficient, my utility bills have gone down too. Win-win."

GreenTech also offers custom solutions for unique applications, like marine refrigeration systems or specialized industrial coolers. Their team of engineers works closely with clients to design machines that fit specific needs, which has earned them partnerships with major Korean conglomerates like Samsung and LG.

While they're still building their brand recognition compared to Kyungseo or Hankook, GreenTech's focus on innovation and sustainability makes them a supplier to watch—and a great choice for forward-thinking businesses.

Daedong Environmental Systems has a niche, but they've mastered it: air pollution control system equipment paired with refrigerant recovery. Based in Daejeon, this company understands that refrigerant recovery doesn't happen in a vacuum—many recycling processes release other pollutants, and having integrated systems can save time, space, and money.

Their flagship product is the CleanCycle 5000, a comprehensive system that combines refrigerant recovery, air filtration, and air pollution control system equipment into a single unit. Designed for large recycling facilities, it's perfect for operations that handle not just refrigerants but also other hazardous materials. "Before we installed the CleanCycle 5000, we had separate systems for refrigerant recovery and air pollution control," said Jong-suk, plant director at a major recycling center in Gwangju. "Now, everything is integrated, which has reduced our energy costs and made our workflow much smoother. The system automatically adjusts to different refrigerant types and pollutant levels—it's like having a smart assistant running the show."

Daedong's expertise in air pollution control also means their refrigerant recovery machines are particularly effective at capturing volatile organic compounds (VOCs) that can be released during the recovery process. This is a big plus for companies operating in areas with strict air quality regulations, like the Seoul metropolitan area.

While the CleanCycle 5000 is their most well-known product, Daedong also offers standalone refrigerant recovery units for smaller facilities. Their DR-300 model is a mid-sized machine that balances capacity and cost, making it popular with regional recycling centers. "We didn't need the full CleanCycle system, but we still wanted the reliability of Daedong's technology," said Seo-yun, manager of a recycling co-op in Busan. "The DR-300 has been rock-solid, and knowing it's backed by their air pollution expertise gives us peace of mind."

Daedong might not be the first name you think of for standalone recovery machines, but if you're looking for integrated environmental solutions, they're hard to beat.

Rounding out our list is Seoul EcoMachines, a company that prides itself on affordability without sacrificing quality. For small businesses or startups on a budget, they offer some of the most competitively priced refrigerant recovery machines on the Korean market—without cutting corners on performance.

Their bestseller is the SE-100, a basic but reliable recovery unit that's perfect for entry-level operations. It lacks some of the bells and whistles of pricier models—no digital display, no IoT connectivity—but it does the job: recovering refrigerants efficiently and safely. "When we first started our appliance recycling business, we couldn't afford a top-of-the-line machine," said Tae-hyun, owner of a small recycling shop in Incheon. "The SE-100 was within our budget, and it's been running strong for three years now. We've had to ｒｅｐｌａｃｅ a filter once, but that's it. For the price, you can't ask for more."

Seoul EcoMachines also offers a range of accessories, like hoses, filters, and storage cylinders, making them a one-stop shop for businesses just starting out. Their customer service team is known for being patient and helpful, walking new users through setup and operation—something that Tae-hyun appreciated: "I had zero experience with refrigerant recovery when I bought the SE-100. Their team called me to walk me through the first use, step by step. It made a daunting process feel manageable."

While their machines aren't as advanced as GreenTech's or as powerful as Hankook's, Seoul EcoMachines fills an important gap in the market: providing accessible, reliable equipment for small businesses that might otherwise struggle to comply with environmental regulations. And as these businesses grow, many stick with Seoul EcoMachines, upgrading to their mid-range models like the SE-300, which offers more power and basic digital controls.

If you're just starting out or need a budget-friendly option that still gets the job done, Seoul EcoMachines is a solid choice.
