Callefiks

What Callefiks does

Callefiks OÜ is a privately held Estonian water treatment specialist, founded in 2000 and headquartered at Artelli 19, Tallinn. The company sells, installs, and maintains water filtration and treatment equipment for four primary customer segments — residential households, housing cooperatives and communities, industrial operators (food processing, agriculture, manufacturing), and the public sector (municipal water utilities, hospitals, military installations). Primary operations are domestic to Estonia, with international shipping available via the company's e-commerce storefront to Finland, Sweden, Latvia, and Lithuania.

Callefiks' technical portfolio spans the principal water treatment modalities: ion-exchange softening (J-Cab and ASL series), aeration-based iron and manganese removal (ARS Micronizer and Oxipress series), catalytic filtration (AFL series), UV disinfection (W and FC series with documented flow rates up to 6 m³/h), reverse osmosis, mechanical filtration, carbon filtration, and multi-parameter Ecomix units that consolidate hardness, iron, manganese, ammonium, and organic matter removal in a single vessel. Beyond equipment distribution, Callefiks designs and constructs turnkey water treatment plants and wellhead pump stations, with documented project capacities ranging from small community systems (0.6 m³/h) to large municipal installations (180 m³/h). The technology base is largely distributed rather than developed in-house: Callefiks acts as Estonian importer and integrator for six European equipment manufacturers (StrongFlow OY, Eurotrol S.p.A, Lorivan NV, Aqua-Techniek BV, BWT Separtec OY, Fluidra Danmark).

Revenue is generated across five streams: one-time equipment sales via the multilingual pood.callefiks.ee storefront, channel sales through FEB AS (Estonia's sanitary retail chain with stores in six cities), professional installation services, recurring maintenance contracts covering both Callefiks-installed and competitor equipment, and project-based hardware/turnkey work for industrial and municipal customers. Equipment unit prices range from approximately €14 for consumables (filter cartridges, keys, UV lamps) to over €2,700 for industrial multi-purpose systems, while water treatment plant projects are priced on a scope-defined, multi-year basis. The company is management-owned (Tarmo Veski — board member, sales and projects; Aleksander Gustav Tõnisson — sales manager; Taivo Eylandt — maintenance and installation), with no institutional investors or parent company disclosed.
