What IOW Bulgaria does
IOW Bulgaria EOOD (ЙОВ БЪЛГАРИЯ ЕООД) is a Sofia-headquartered industrial engineering company and wholly-owned subsidiary of Swedish industrial group Axel Johnson International, operating across Bulgaria, Romania, Serbia, and Macedonia. The company operates a three-pillar model: trade, authorized service, and engineering design for hydraulic components, filtration systems, and drive technology serving off-highway and industrial machinery markets. Customers span OEM manufacturers of construction, agricultural, mining, and material handling equipment, as well as aftermarket service providers requiring spare parts, repairs, and component refurbishment.
The product portfolio combines proprietary brands — IOW AmberLine® hydraulics, IOW BlueLine® filters, and Gearoxx worm and helical gear reducers — with distribution of premium third-party lines from Dana Brevini, Carraro, Rexnord (Centa), Casappa, MANN+HUMMEL (WIX Filters), Varvel, and I-MAK. The service center is one of a limited number of worldwide authorized Dana service and product centers, equipped for diagnostics, full refurbishment, and repair of gearboxes, axles, transmissions, and hydraulic systems. Additional offerings include custom engineering design for drive systems and hydraulic circuits, plus a component recycling program that purchases used axles and transmissions from across the Balkans.
The business is sales-led, combining direct enterprise field sales with an authorized service center in Sofia, a sales/service office in Bucharest, and an e-commerce storefront at e-iow.shop. The company is ISO 9001:2015 certified and serves as a regional hub for Axel Johnson International's industrial components portfolio in the Balkans. Pricing is transactional/unit-based for trade goods and project-based for engineering design and service work. The company is privately held with no public listing; Krassen Milev is the founder and managing director.
