In-Depth: The Top 10 Suppliers
1. SierraConvey Solutions
If you've ever visited a small plastic bag manufacturing unit in Freetown, chances are you've seen a SierraConvey system at work. Founded in 2015 by a team of local engineers, SierraConvey Solutions has built its reputation on understanding the unique challenges of small to medium enterprises (SMEs) in Sierra Leone. Their plastic pneumatic conveying system equipment is designed to be compact, energy-efficient, and easy to maintain—critical for businesses with limited technical staff.
What really sets them apart, though, is their willingness to customize. "We once worked with a cassava flour producer in Moyamba who needed a conveyor that could handle both dry and slightly moist powder," says Amara Kamara, the company's lead designer. "Standard systems would have clogged, but we modified the air pressure settings and added a self-cleaning feature. Now, they're moving 50% more flour daily with zero downtime." Alongside conveyors, SierraConvey also offers filter press equipment, essential for separating solids from liquids in processes like wastewater treatment—a boon for businesses looking to meet Sierra Leone's environmental regulations.
With a showroom in Freetown and mobile service units covering the Western Area, SierraConvey prides itself on accessibility. "Our clients don't just buy a machine—they buy peace of mind," Kamara adds. "If a system breaks down, we're there within 24 hours, no exceptions."
2. EcoFlow Industries
Sustainability isn't just a buzzword for EcoFlow Industries—it's the core of their business model. Specializing in air pollution control system equipment and plastic pneumatic conveying systems, this Kenema-based supplier has become a go-to for recycling plants and mining operations looking to reduce their environmental footprint. "Mining companies in Kono were struggling with dust pollution from ore transport," explains Isata Sesay, EcoFlow's environmental consultant. "Our pneumatic conveyors enclose the material completely, cutting dust emissions by 90%, and our air pollution control units filter out remaining particles. It's a win-win: cleaner air for workers and compliance with the EPA."
EcoFlow's systems are also engineered for low energy use, a key consideration in a country where power costs can eat into profits. "We use variable-speed blowers that adjust air pressure based on material density," Sesay notes. "A rice mill in Bo reported a 30% ｄｒｏｐ in electricity bills after switching to our conveyors." The company's commitment to the environment extends to their own operations, too—they source 60% of their steel locally and recycle packaging materials from their assembly line.
For businesses new to pneumatic conveying, EcoFlow offers free on-site assessments. "We don't just sell equipment; we help you design a system that fits your space and budget," Sesay says. "Last year, we helped a small e-waste recycler in Makeni set up a conveyor network that now processes 200kg of circuit boards daily—up from 50kg manually. That's the kind of impact we care about."
3. TechMover Engineering
When it comes to heavy-duty material handling, TechMover Engineering is the name that comes up in conversations among Sierra Leone's industrial giants. Based in Port Loko, this supplier specializes in high-capacity plastic pneumatic conveying lines and hydraulic briquetter equipment—machines that compress loose materials like metal shavings or plastic scraps into dense briquettes for easier transport. "A scrap metal yard in Waterloo was spending $2,000 monthly on trucking loose aluminum chips," says Mohamed Jalloh, TechMover's sales director. "After installing our hydraulic briquetter, they reduced volume by 70% and cut transport costs in half. Now they're expanding to handle copper, too."
TechMover's pneumatic systems are built for durability, with stainless steel components and reinforced hoses that can withstand abrasive materials like mining ore. "We test every conveyor under 120% of its rated load for 48 hours straight before delivery," Jalloh emphasizes. "Our systems don't just meet industry standards—they exceed them." The company also offers training for operators, ensuring that clients get the most out of their equipment. "Last month, we trained a team at a cement plant in Magburaka on preventive maintenance. Six weeks later, they reported zero breakdowns—down from two per week before."
While TechMover primarily serves large-scale operations, they've recently launched a "Starter Line" for growing businesses, with smaller conveyors and briquetters at a more accessible price point. "We started as a small workshop ourselves," Jalloh says. "We remember what it's like to need reliable equipment but not have the budget for top-of-the-line models. The Starter Line is our way of paying it forward."
4. WestAfrica Conveyors
For businesses that can't afford downtime—like pharmaceutical manufacturers or food processors—WestAfrica Conveyors is the gold standard. With a headquarters in Freetown and service centers in Bo, Makeni, and Koidu, this supplier offers round-the-clock support for their plastic pneumatic conveying systems and filter press equipment. "When a cocoa processing plant in Kenema had a conveyor failure during peak harvest season, our team was on-site within three hours," recalls Fatmata Bangura, WestAfrica's customer service manager. "We repaired the system and stayed overnight to monitor it—they didn't lose a single batch of cocoa."
WestAfrica's focus on reliability extends to their product design. Their pneumatic systems feature redundant blowers (so if one fails, the other kicks in automatically) and digital monitoring that alerts operators to potential issues before they cause breakdowns. "A fruit juice factory in Lungi uses our system to transport sugar," Bangura says. "The digital sensor detected a slight ｄｒｏｐ in air pressure, which turned out to be a loose hose clamp. Fixing it took five minutes—avoiding what could have been hours of downtime."
The company also prides itself on transparency. "We provide detailed cost breakdowns and energy consumption estimates upfront," Bangura adds. "No hidden fees, no surprises. Our clients trust us because we treat their problems as our own."
5. GreenTech Systems SL
Modularity is the name of the game at GreenTech Systems SL, a supplier that understands businesses grow—and their equipment needs to grow with them. Based in Makeni, GreenTech specializes in compact plastic pneumatic conveying systems and air pollution control units that can be expanded or reconfigured as operations scale. "A textile factory in Kabala started with a single conveyor line for cotton fibers," says Ibrahim Conteh, GreenTech's founder. "Two years later, they added three more lines, and our system integrated seamlessly. No need to ｒｅｐｌａｃｅ the entire setup—just plug in the new modules."
GreenTech's systems are also designed with small spaces in mind. "Many SMEs in Sierra Leone operate out of converted warehouses or small workshops," Conteh explains. "Our conveyors have a vertical design that takes up 40% less floor space than traditional models. A soap manufacturer in Bo was able to add a conveyor without relocating their mixing machines—that's the flexibility we offer."
The company's air pollution control systems are equally innovative, using compact filters that capture 99% of airborne particles. "A paint factory in Freetown was struggling with EPA fines for volatile organic compounds (VOCs)," Conteh says. "We installed a small-scale scrubber system that fits in their back room, and now they're compliant. It's not just about selling equipment; it's about solving problems."
6. National Material Handling
National Material Handling (NMH) believes in keeping it local. With an assembly plant in Koidu, this supplier manufactures hydraulic briquetter equipment and plastic pneumatic conveying systems using locally sourced steel and components—reducing lead times and supporting the Sierra Leonean economy. "We used to import all our parts, but delays at the port cost us clients," says Zainab Koroma, NMH's operations manager. "Now, 70% of our steel comes from the Sierra Leone National Iron Ore Company, and we work with local welders and electricians. A client in Bo can order a conveyor on Monday and have it installed by Friday—that's the advantage of local production."
NMH's hydraulic briquetters are particularly popular among waste management companies. "A landfill operator in Freetown was paying to transport plastic waste to a recycling plant 100km away," Koroma notes. "With our briquetter, they compress the plastic on-site, reducing volume by 80% and cutting transport costs. Now they're even selling the briquettes to a plastic pellet manufacturer—turning waste into revenue."
The company also offers flexible payment plans, recognizing that many local businesses face cash flow challenges. "We partnered with a microfinance institution to offer 12-month installment plans with low interest," Koroma says. "A small scrapyard in Kenema couldn't afford a briquetter upfront, but with the plan, they're now saving more than they pay monthly. It's about making these tools accessible to everyone."
7. Coastal Convey & Control
Sierra Leone's coastal regions present unique challenges for industrial equipment—high humidity, salt air, and occasional rain can corrode metal and damage electronics. Coastal Convey & Control, based in Bonthe, specializes in plastic pneumatic conveying systems and air pollution control units built to withstand these harsh conditions. "A fish processing plant in Shenge was replacing conveyor parts every three months due to rust," says Alusine Mansaray, Coastal Convey's technical director. "We installed a system with marine-grade stainless steel and sealed electrical components. Two years later, they haven't replaced a single part."
The company's systems are also designed to handle wet or sticky materials, a common need in the fishing and seafood industry. "Fish meal is notoriously hard to convey because it clumps when moist," Mansaray explains. "Our conveyors use a combination of air pressure and vibration to keep the material flowing smoothly. A shrimp farm in Waterloo now moves 3 tons of fish meal daily without blockages."
Coastal Convey's commitment to local communities is another selling point. "We train young people from Bonthe in equipment maintenance, then hire the top performers," Mansaray says. "It's our way of giving back while building a skilled workforce. When a client calls for service, they're talking to someone from their community—someone who understands their environment and their needs."
8. Northern Convey Solutions
For micro-enterprises and local artisans, Northern Convey Solutions is a lifeline. This Makeni-based supplier offers affordable, small-scale plastic pneumatic conveying systems and filter press equipment designed for businesses with limited budgets and space. "A group of women in Bombali making shea butter were manually carrying nuts from the grinding machine to the press—backbreaking work," says Hawa Bah, Northern Convey's founder. "We installed a tiny conveyor for $500, and now they're producing 30% more shea butter daily with less fatigue. That's the difference we want to make."
Northern Convey's systems are simple to operate, with minimal buttons and clear instructions in Krio and English. "Many of our clients have never used industrial equipment before," Bah notes. "We provide a one-hour training session, and if they have questions later, our hotline is answered by someone who speaks their language—no automated menus."
The company also offers trade-in programs, allowing clients to upgrade as their business grows. "A peanut butter producer in Koinadugu started with our smallest conveyor," Bah says. "When they expanded, they traded it in for a larger model and got 50% off. We want to grow with our clients, not just sell to them."
9. Sierra Industrial Tech
Integration is key for Sierra Industrial Tech, a Freetown-based supplier that specializes in connecting plastic pneumatic conveying systems and hydraulic briquetter equipment with existing production lines. "Most factories in Sierra Leone can't afford to ｒｅｐｌａｃｅ their entire setup—they need equipment that works with what they already have," says David Williams, Sierra Industrial's integration specialist. "A car battery manufacturer in Kissy had an old mixing machine; we designed a conveyor that feeds directly into it, no modifications needed. They saved $10,000 by not replacing the mixer."
The company also offers a range of accessories—from sensors that monitor material flow to automated diverters that switch materials between lines—allowing clients to add smart features to older systems. "A electronics plant in Wellington wanted to track how much plastic resin they use daily," Williams explains. "We added a digital flow meter to their existing conveyor, and now they're reducing waste by 15%."
Sierra Industrial Tech's team includes mechanical and electrical engineers who work closely with clients to understand their workflows. "We don't just look at the conveyor—we look at the entire process," Williams says. "A soap factory was using three separate conveyors when one with a diverter would do. We redesigned their system, saving them space and energy. That's the value of integration."
10. Global Convey Sierra Leone
For large-scale industrial plants that demand cutting-edge technology, Global Convey Sierra Leone is the go-to importer. With partnerships with leading international brands like Germany's ConveyTech and Italy's Pneumatic Solutions, this Freetown-based supplier offers high-end plastic pneumatic conveying systems and air pollution control equipment that meet global standards. "A cement plant in Lunsar needed a conveyor that could handle 50 tons of limestone per hour," says James Tucker, Global Convey's managing director. "Our German partner designed a system with that capacity, and we handled the import, installation, and training. Now it's the most efficient line in their plant."
While imported equipment can be pricier, Global Convey justifies the cost with longer lifespans and lower maintenance. "A mining company in Tonkolili bought a conveyor from us in 2018," Tucker notes. "They've only needed routine maintenance—no major repairs. Over time, that's cheaper than replacing a cheaper system every few years." The company also offers extended warranties and access to international technical support. "If a client has a problem we can't solve locally, we connect them directly with the manufacturer's engineers via video call," Tucker says. "It's like having a global support team at your fingertips."
Global Convey isn't just for large companies, though. "We recently helped a medium-sized fertilizer plant in Bo import a compact conveyor that was unavailable locally," Tucker adds. "We believe every business deserves access to the best equipment, regardless of size."
