Top 5 Desulfurizer Suppliers in Russia [2025]

Based in Yekaterinburg, Ural Eco-Tech has been a workhorse in Russia’s industrial heartland since 2008. They cut their teeth building equipment for the region’s mining and metal smelting plants, so they know a thing or two about durability. These days, their desulfurization machines are the go-to for businesses that need equipment that can handle 24/7 operation in tough conditions.

What makes them stand out? Their de-sulfurization machines equipment isn’t just about meeting minimum standards—it’s about overdelivering. Take their flagship model, the UET-DS 5000. It’s designed to tackle high-sulfur exhausts from metal melting furnaces and lead acid battery recycling plants, boasting a 98% sulfur removal rate. That’s a big deal for factories that process scrap metal or recycle batteries, where sulfur emissions can skyrocket without proper control.

We spoke to Dmitry, a plant manager at a lead acid battery recycling facility in Chelyabinsk, who switched to Ural Eco-Tech last year. “Before, our old desulfurizer kept breaking down in winter—frozen pipes, sensors failing. Ural’s machine? It’s been running nonstop for 14 months, even when temps hit -30°C. And their tech team? They showed up within 24 hours when we had a minor issue. You can’t put a price on that kind of reliability.”

Ural Eco-Tech also gets brownie points for customization. Need a desulfurizer that integrates with an existing air pollution control system equipment ? They’ll design it from scratch. Their client list includes big names like Ural Mining and Metallurgy Company, so you know they’re trusted by the heavy hitters.

If Ural Eco-Tech is the “tough guy” of desulfurizers, Moscow Clean Energy (MCE) is the “tech whiz.” Located in Moscow’s Skolkovo Innovation Center, this young company (founded in 2015) has made waves with its smart, energy-efficient desulfurization systems. They’re not just selling machines—they’re selling data-driven solutions.

Why they’re on the list: MCE’s desulfurizers come with built-in IoT sensors that monitor sulfur levels, energy usage, and maintenance needs in real time. Imagine getting an alert on your phone that a filter needs changing before it clogs up, or being able to tweak settings remotely to optimize efficiency. For busy plant managers, that’s a game-changer.

Their star product, the MCE SmartDesulf 300, is a hit with mid-sized factories and recycling plants. It’s compact enough to fit in tight spaces (important for older facilities in Moscow or St. Petersburg) but powerful enough to handle 3,000 cubic meters of exhaust gas per hour. We visited a circuit board recycling plant in Tula that uses two SmartDesulf 300s alongside their dry process equipment . The plant’s environmental officer, Anna, told us, “We used to spend 15% of our energy budget on old desulfurizers. Now? MCE’s machines cut that by 22%. And the app lets us track emissions in real time—no more guessing if we’re hitting government targets.”

MCE also excels at sustainability. Their desulfurizers use a closed-loop water system, so they waste less H2O than traditional models—a big plus in regions like Kalmykia or Astrakhan, where water is scarce. Plus, they offer free training for your team to use the IoT features, so you’re not just buying a machine—you’re getting the skills to make the most of it.

Headquartered in Novosibirsk, Siberian Industrial Solutions (SIS) knows cold. When your factory is 300km from the nearest city and winter temps ｄｒｏｐ to -45°C, you can’t afford desulfurizers that freeze up or lose efficiency. SIS built their reputation by solving that exact problem, and today, they’re the top choice for businesses in Siberia and the Far East.

Their secret? Insulation and heating systems that are basically overkill—until you need them. Their desulfurizers come with dual-layered pipes, self-regulating heating elements, and insulated control panels. One client in Norilsk, which runs a nickel smelter, told us their SIS desulfurizer has been operational for 5 years with zero cold-related breakdowns. “We used to have to shut down for 2-3 days every winter to thaw pipes,” they said. “Now? We forget it’s even winter.”

But SIS isn’t just about surviving the cold. Their de-sulfurization machines equipment is also surprisingly flexible. They offer both wet and dry process options, so whether you’re running a wet process equipment plant for circuit board recycling or a dry process metal melting furnace, they’ve got a desulfurizer that fits. Their SIS-DS 2000 Dry model, for example, is popular with cable recycling plants that use scrap cable stripper equipment —it handles the fine dust and sulfur byproducts without needing massive water tanks.

Another plus? SIS has a network of service centers across Siberia, so even if you’re in a remote area, help is never too far. They also offer long-term maintenance contracts, which is a relief for businesses that don’t have in-house tech teams.

Not everyone wants to piece together their pollution control system from different suppliers. That’s where Volga Environmental Systems (VES), based in Nizhny Novgorod, comes in. They don’t just sell desulfurizers—they sell complete air pollution control system equipment packages, including scrubbers, filters, and monitoring tools. For businesses building new plants or upgrading entire facilities, this “one-stop shop” approach saves time, money, and headaches.

What’s their specialty? Lead acid battery recycling plants. VES has partnered with some of Russia’s biggest battery recyclers to design desulfurization systems that work seamlessly with lead acid battery breaking and separation system equipment. Their VES-Desulf LeadPro model, for example, is calibrated to handle the specific sulfur compounds released when breaking down old batteries. It even syncs with the plant’s filter press equipment to collect and neutralize sulfur byproducts, turning waste into a manageable sludge instead of a toxic gas.

We talked to a plant owner in Kazan who recently built a new lead battery recycling facility with VES. “I was dreading dealing with 5 different suppliers for desulfurizers, filters, and monitors,” he said. “VES handled it all. Their team even stayed on-site for a month after installation to make sure everything worked together. Now, our sulfur emissions are 99% lower than the legal limit, and the whole system is so integrated, my operators can control it from a single screen.”

VES also offers financing options, which is a big help for small to medium-sized businesses. They understand that investing in pollution control isn’t cheap, so they’ll work with you to spread payments over 2-3 years—no hidden fees, just straightforward terms.

Based in Vladivostok, Far East Recycling Tech (FERT) might be the smallest company on this list, but they’ve carved out a loyal following by focusing on niche industries. While other suppliers chase big metal smelters, FERT specializes in desulfurizers for smaller-scale operations: lamp recycling equipment plants, small motor recycling shops, and refrigerator & ac recycling machines equipment facilities. These businesses often struggle to find desulfurizers that are the right size—not too big (and expensive) for their needs, but still effective.

Why they’re a hidden gem? Their mini-desulfurizers are compact but mighty. Take the FERT-DS Mini, which is about the size of a large refrigerator. It’s perfect for a lamp recycling plant that processes 500-1,000 bulbs a day. Despite its small footprint, it still removes 95% of sulfur emissions, thanks to a patented “bubble scrubber” design that maximizes contact between exhaust gas and neutralizing solution. And at around 30% cheaper than standard industrial models, it’s a budget-friendly option for small businesses.

FERT also gets creative with materials. Their desulfurizers use corrosion-resistant alloys that stand up to the harsh chemicals in lamp and refrigerator recycling. “We used to go through a desulfurizer every 2 years because the acids from old fridge coolants would eat through the metal,” said a shop owner in Khabarovsk who uses FERT’s equipment. “Now? My FERT unit is going on 4 years, and it still runs like new.”

Don’t let their focus on small-scale fool you, though—FERT can scale up too. They recently partnered with a lithium battery recycling plant in Primorsky Krai to build a custom desulfurizer for their li battery recycling equipment , proving they can handle bigger projects when needed.
