3n Solutions Gmbh

What 3n Solutions Gmbh does

3N Solutions GmbH is a privately held German industrial services company founded in 2010 and headquartered in Unterensingen, Baden-Württemberg, with operations extending into Poland. The firm provides specialized cleaning and maintenance services for sensitive electrical installations and industrial machinery, organized around six service lines: electrical system maintenance, electrical installation cleaning, hydrodynamic high-pressure surface cleaning, post-fire cleaning and restoration, thermographic and electrical measurement diagnostics, and ozonation disinfection. Its primary technical differentiator is a proprietary dry gas mixture (Gasgemisch) prepared on a specialized technological vehicle ramp and applied via nozzles at controlled 0.5–1.5 bar pressure; this method can clean live electrical equipment up to 1 kV without production-line shutdown, reaches inaccessible locations, and is described as non-reactive, non-toxic, non-abrasive, and aseptic.

The business operates as a professional services firm with a 24/7/365 field-deployment model, delivering services on-site at customer facilities via mobile units. Its go-to-market is direct enterprise field sales targeting industrial buyers, supported by a company website, LinkedIn, YouTube, and selective trade show participation (notably ENERGETAB 2020 in Poland). Customer segments span energy/power, metal, chemical/petrochemical, food and beverage, paper/packaging, and automotive industries. The disclosed customer roster consists of large Polish state-owned enterprises — PGE, JSW (Jastrzębska Spółka Węglowa), PGNiG, and Metro Warszawskie — alongside an unstated mix of German and other European industrial clients.

Revenue is generated through customized project quotes and recurring maintenance contracts rather than standardized pricing; both one-time orders and fixed-cooperation agreements are offered. The company is founder-controlled: Markus Hammel serves as the sole authorized managing director (vertretungsberechtigter Geschäftsführer), with no institutional investors, funding rounds, M&A activity, or ownership changes disclosed. No certifications, patents, or formal partnerships are documented in available sources.

Core offering

3N Solutions GmbH provides industrial cleaning and maintenance services for sensitive electrical installations, production halls, and machinery. The company uses a proprietary dry gas mixture technology applied at controlled pressure (0.5–1.5 bar) to clean live electrical equipment up to 1kV without production shutdown. Complementary services include hydrodynamic high-pressure cleaning, thermographic and electrical measurements, post-fire restoration cleaning, and ozonation disinfection, delivered on-site 24/7/365.

Product overview

3N Solutions GmbH offers a unified portfolio of industrial cleaning and maintenance services for electrical installations. The core offering centers on the proprietary Gasgemisch (Gas Mixture) technology—a dry gas mixture cleaning system applied via specialized nozzles at controlled pressure (0.5-1.5 bar). This technology underlies several service lines: electrical installation cleaning, post-fire cleaning, and general maintenance. Complementary services include hydrodynamic cleaning for industrial surfaces, thermographic and electrical measurements for condition assessment, and ozonation for disinfection. The services are delivered by qualified teams operating 24/7, 365 days per year, targeting industrial facilities across energy, metallurgy, automotive, food, paper, chemical, and petrochemical sectors.

Broad incumbents

• Stork Technical Services (Fluor): Industrial services and maintenance contractor for power, oil & gas, and petrochemical assets, including mechanical and electrical maintenance on live process equipment. Comparable customer verticals and maintenance scope, but at significantly larger scale and broader service portfolio.
• Bilfinger SE: German-headquartered industrial services provider offering maintenance, cleaning, and MEP services to process industries including power, oil & gas, and chemicals — directly comparable end-markets to 3N's energy/mining/oil&gas customer base, but at far larger scale and broader scope.
• Kärcher: German cleaning technology and services company with an extensive industrial cleaning portfolio including high-pressure and specialty cleaning systems. Comparable on the hydrodynamic/pressure-washing side of 3N's offering and on serving industrial sites, though Kärcher is primarily an equipment OEM plus generalist cleaning provider.
• REMONDIS: German-headquartered waste management and industrial services company with industrial cleaning, tank/silo cleaning, and decontamination offerings. Comparable on industrial cleaning scope and German/European footprint, serving many of the same process-industry verticals.
• Veolia Environmental Services: Global environmental and industrial services group offering industrial cleaning, hazardous-waste handling, and decontamination to energy and process-industry clients. Overlaps with 3N's industrial cleaning and post-fire/restoration use cases, particularly in regulated heavy-industry accounts.
• Sulzer: Swiss industrial services and equipment company providing maintenance, repair, and cleaning of rotating and process equipment for energy and process-industry customers. Comparable MEP-style field services and energy-vertical exposure, though Sulzer also manufactures pumps and rotating equipment.
• Streicher Group: German industrial services and construction group active in industrial cleaning, pipeline services, and electrical/instrumentation work for energy and process industries. Comparable German/DACH industrial-services footprint with overlapping electrical maintenance and cleaning capabilities.

Direct peers

• Hydroblast Group: UK-based specialist in high-pressure water jetting and industrial cleaning for power, petrochemical, and heavy-industry sites. Most directly comparable to 3N's hydrodynamic cleaning service line and on-site industrial delivery model, though 3N differentiates with its proprietary dry-gas electrical cleaning.
