What Ditech does

Ditech AS is a Norwegian distributor and systems integrator of industrial filtration solutions, founded in 1989 and headquartered in Stokke (Sandefjord), Norway. The company supplies a comprehensive portfolio spanning eight consumable filter categories (hydraulic, air, water, ventilation, liquid, compressed air, fuel, and oil filters), five filtration system types (stationary offline, mobile offline, automatic self-cleaning, process filters, and oil mist separators), and condition monitoring equipment. Its offering includes differentiated technical products such as GreenOil sustainable oil filtration systems using sheep-wool filter media (exclusive Norwegian distributor since 2012) and Forsta 90 Series self-cleaning water filters, supported by 70,000 filters in stock across 7,000 variants. Customers use Ditech's digital portal for machine search, cross-reference product lookup, and filter map management across equipment fleets, with 300,000 filters currently registered in customer systems.

Ditech serves five primary verticals: Marine & Offshore, Aquaculture, Road & Construction, Industry, and Food & Beverage. The go-to-market combines direct enterprise sales with segment-dedicated account managers, a nationwide dealer network of 15+ authorized partners, and a self-serve customer portal with role-based access and approval workflows. Notable enterprise customers include Rem Offshore (GreenOil installations across 18 vessels), Øst-Riv AS (3-year framework for 350+ machines), Service Partner Kopstad (130+ machines), Skagerak Kraft and Skagerak Varme (3-year total-supplier agreement), Hydro Husnes, and a Norwegian dairy producer. The business model is primarily hardware sales of consumable filters and capital systems, supplemented by no-charge technical advisory services integrated into the sales process and a free digital portal that drives customer retention and recurring filter reorders.

In April 2024, Ditech relocated to expanded premises in Borgeskogen, and in 2024 it entered a strategic partnership with Axel Johnson International's Driveline Solutions business group while retaining operational independence, existing management, and shareholder continuity. The company is certified to ISO 9001:2015 and ISO 14001:2015, and holds product certifications including NSF/ANSI/CAN 61 (Forsta 90 Series), EC 1935, FDA 21 CFR Part 11, and ATEX for relevant product lines.
