Nirafon Oy

What Nirafon Oy does

Nirafon Oy is a Finnish family-owned company founded in 1986 (originally as Nirak KY, rebranded to NIRAFON Oy in 1994) and headquartered in Lahti, Finland. The company designs and manufactures acoustic cleaning systems that use sound pressure pulses to remove dust, slag, and fouling deposits from industrial boiler surfaces without interrupting production processes. Its product portfolio comprises two main lines: the NCSD (NIRAFON Cleaning Sound Device), a gas-combustion-powered acoustic cleaner capable of operating at temperatures up to 1500°C with acoustic pressure levels above 170 dB and cleaning range up to 10 meters, and a pneumatic acoustic cleaner series available in three frequencies (NI60, NI100, NI250) for applications below 1000°C, each offered in straight and 90-degree curved horn configurations.

The company sells to industrial energy, forest/pulp, cement, and metal sector customers including utilities, waste-to-energy operators, pulp mills, and cement manufacturers. Its business model combines hardware sales of customized acoustic cleaning equipment with project engineering, installation services, and recurring spare parts and maintenance revenue under multi-year contracts. Pricing is quote-based and tailored to application specifics. Nirafon operates with a small core team (1-10 employees) and pursues a hybrid go-to-market: direct enterprise field sales led by Managing Director Pauli Jokela for worldwide accounts and Sales/Project Manager Kimmo Savolainen for Finland, supplemented by an international distributor network spanning Brazil, China, Germany, India, Iran, Malaysia, Poland, Spain/Portugal, Sweden/Norway, Uruguay, Saudi Arabia/GCC, and Guatemala.

Core offering

Nirafon Oy designs, manufactures and sells acoustic cleaning systems that use sound pressure pulses to remove dust, slag and fouling from industrial process equipment such as boilers, economizers, superheaters, bag filters, ESPs, SCRs and recovery boilers. Its portfolio comprises the NCSD high-temperature gas-combustion cleaner (up to 1,500°C) and pneumatic NI60/NI100/NI250 cleaners (below 1,000°C), delivered with project engineering, installation support and recurring spare-parts and maintenance services for energy, pulp and paper, cement and metal industries worldwide.

Product overview

Nirafon Oy offers a comprehensive acoustic cleaning system portfolio consisting of two main product lines: the NCSD (NIRAFON Cleaning Sound Device) for high-temperature applications and the Pneumatic Acoustic Cleaner series (NI60, NI100, NI250) for lower-temperature areas. The NCSD uses gas combustion to generate powerful 170+ dB sound pulses effective up to 1500°C, while the pneumatic cleaners use pressurized air at three frequency levels (60Hz, 100Hz, 250Hz) for temperatures below 1000°C. Each pneumatic model is available in straight and 90-degree curved horn configurations. These systems work together to provide continuous, automatic cleaning of boiler heat exchangers, economizers, superheaters, SCR systems, bag filters, ESP, and other industrial equipment without process interruption.

Products and services

• NCSD (NIRAFON Cleaning Sound Device) Gas-combustion-powered acoustic cleaner that produces 170+ dB sound pulses effective up to 10 meters from the source, designed for high-temperature boiler areas up to 1,500°C where ash exists in both molten and solid forms. Used by power, waste-to-energy and pulp-industry operators to continuously clean screen tubes, superheaters and similar zones without stopping the process.
• NI250 Pneumatic Acoustic Cleaner Pressurized-air-driven acoustic cleaner operating at 250 Hz for cleaning areas below +1,000°C, available in straight and 90-degree curved horn profiles. Consumes about 20 Ndm3/s of air while sounding and 2 Ndm3/s continuously for cooling. Used for economizers, bag filters, ESPs, air preheaters and similar industrial surfaces.
• NI100 Pneumatic Acoustic Cleaner Pressurized-air-driven acoustic cleaner operating at 100 Hz for lower-temperature cleaning, available in straight and 90-degree curved horn profiles. Consumes about 40 Ndm3/s of air while sounding and 2 Ndm3/s for cooling, with the lower frequency providing more efficient cleaning over larger areas.
• NI60 Pneumatic Acoustic Cleaner Pressurized-air-driven acoustic cleaner operating at 60 Hz, the lowest-frequency pneumatic model offering the deepest penetration and most efficient cleaning. Available in straight and 90-degree curved horn profiles, using 40–50 Ndm3/s of air while sounding for large-area industrial cleaning applications.

Quantifiable outcome

• Cleaning costs reduced by over 90% - from 35,000-50,000 euros per cleaning to 3,500 euros per year at Helen Oy Salmisaari plant

Expansion highlights5 records

Direct peers

• Hamon: Belgium-based supplier of air-cooled condensers, cooling towers, and industrial cleaning/heat-transfer equipment for power and process industries. Overlaps with Nirafon in industrial cleaning applications for energy and process customers.
• Clyde Bergemann Power Group (Babcock Power): Largest global supplier of sootblowers and boiler cleaning equipment for power plants. Direct competitor to Nirafon's pneumatic acoustic cleaners, serving the same utility and industrial boiler customers with steam/air sootblowing technology rather than acoustic waves.
• Diamond Power (Babcock Power): Manufacturer of water cannons, soot blowers, and related boiler cleaning equipment. Competes head-to-head with Nirafon in cleaning heat-transfer surfaces in utility and industrial boilers, using high-pressure water rather than acoustic pulses.
• Stork (Fluor): Boiler cleaning and maintenance services provider (acquired by Fluor). Delivers on-site cleaning, inspection, and modification services for power and process plant heat-transfer equipment — overlapping with Nirafon's installed-base support, especially in Europe and the Middle East.

Broad incumbents

• Donaldson Company: Global manufacturer of industrial air filtration and dust collection systems. While primarily a filtration equipment OEM rather than a cleaning-equipment OEM, Donaldson serves the same baghouse/ESP cleaning and dust-load-management use cases that Nirafon addresses acoustically.
• Balcke-Dürr (SPX Technologies): SPX's heat-transfer and cleaning division supplies sootblowers, air heaters, and emissions-cleaning equipment for utility and industrial boilers. A broader incumbent than Nirafon with a wider portfolio including heat exchangers and cooling systems.
• Wood Group (Amec Foster Wheeler): EPC contractor and boiler OEM (legacy Foster Wheeler) for CFB and biomass boilers. Specifies cleaning equipment into new plants, making it both a potential channel partner and an indirect competitor for boiler cleaning specifications in which Nirafon participates.
• Nederman: Swedish industrial air filtration and cleaning equipment manufacturer, similarly Nordic-headquartered. Provides complementary industrial air-quality solutions and serves some of the same pulp, cement, and energy customers as Nirafon.

Emerging players

• Progresseco: Polish industrial cleaning and environmental solutions provider active in power and process plants across Central/Eastern Europe. Smaller and more regional than Nirafon but overlapping in fouling-removal services for energy and forest-industry boilers.
• Martin Engineering: Supplier of industrial conveyor and material-handling cleaning/containment equipment with growing presence in bulk-material and boiler-house cleaning applications. Adjacent player serving some of the same power and cement end markets as Nirafon.
