What Dansk Ventilation-& Industrirengøring does

Dansk Ventilation- & Industrirengøring (DVI Ren) is a Danish professional-services company founded in 2004 and headquartered in Aalborg, with a branch office in Frederikshavn. It specializes in ventilation cleaning, industrial cleaning, facade cleaning, graffiti removal, high-altitude cleaning, floor and carpet cleaning, construction cleaning, line marking, and property maintenance services such as tile cleaning, algae treatment, gutter cleaning, water damage restoration, and filter replacement. Service delivery is on-site at customer facilities across Denmark, with operations covering factories, workshops, warehouses, and food-production plants.

The company is privately held, independently owned, and operates with 11–50 employees. Its core technology is specialized cleaning for ventilation systems, industrial environments, facades, and technical installations, performed with environmentally certified products (Nordic Swan / Svanemærket and EU Ecolabel) by certified cleaning professionals. Documented procedures and a published 2025 ESG report, along with GDPR compliance, an independent whistleblower scheme, and a clean 2025 anti-corruption record, underpin a governance-and-sustainability posture relevant to regulated industrial and public-sector tenders.

Commercially, DVI Ren uses a direct-to-customer GTM: free non-binding quotes requested via the website contact form or phone, with custom pricing for each engagement and a small DKK 35 environmental/waste fee per invoice. Customer acquisition is supported by a 4.8-star Google rating, displayed enterprise references (including Aalborg Universitet, Aalborg Portland, Nord Energi, Aalborghavn, and others), and ESG credentials. A complementary related business, Filters.dk (Per Krogh Franck), supplies ventilation, compressed-air, and hydraulic filters on a 24/7 basis, creating a bundled cleaning-plus-filter offering.

Direct peers

• Coor Service Management: Nordic-based facility management and industrial services provider with strong presence in Denmark, Sweden, Norway, and Finland. Comparable in service mix (cleaning, property services, integrated FM) and target market (industrial and commercial sites) but operates at much larger scale across the Nordics.
• ISS A/S: Danish-headquartered global facility services company offering cleaning, industrial, and workplace services across multiple verticals. Directly comparable to DVI's industrial cleaning and ventilation hygiene work, though ISS operates at vastly larger scale and global footprint.
• ServiceMaster Clean: Commercial and residential cleaning franchise network offering janitorial, carpet, and specialty cleaning. Comparable to DVI's commercial and industrial cleaning service offering and recurring contract structure, though predominantly franchise-operated in North America.
• Bravida: Nordic technical facility services provider focused on HVAC, electrical, and building systems installation and service. Comparable to DVI's ventilation cleaning specialization since both work on building HVAC and ventilation systems, though Bravida focuses on installation and technical service rather than cleaning-only.
• Stanley Steemer: North American commercial and industrial cleaning company specializing in carpet, floor, duct, and industrial cleaning services. Comparable to DVI in service mix (commercial cleaning, duct/ventilation, industrial) and recurring service contract model, though US-focused and franchise-driven.
• CWS Workwear: European provider of workplace hygiene, washroom, and textile services including cleaning-related offerings. Comparable to DVI in hygiene-led recurring commercial services model, with similar industrial and commercial customer segments across Europe.

Broad incumbents

• Sodexo: Global facility services and food services giant with cleaning, maintenance, and integrated FM offerings. Comparable broad-service competitor to DVI in industrial and commercial cleaning, though Sodexo operates at massive global scale with a much wider service portfolio.
• Rentokil Initial: Global hygiene services company covering pest control, washroom hygiene, and specialist cleaning. Comparable to DVI in hygiene-focused commercial services and integrated recurring contract model, though much larger and broader in scope.
• Compass Group: Global contract foodservice and support services company including cleaning and facility services. Relevant comparison for DVI's recurring contract cleaning model for industrial and institutional clients, though Compass's primary scale is in food services.

Others

• ID Logistics: European contract logistics company with significant warehouse and industrial facility operations. Comparable to DVI as a customer-type peer — both work with industrial warehouses (e.g., Boxit) where DVI provides cleaning and ID operates logistics services, though ID is a logistics operator rather than a cleaning services competitor.
