Tufvassons

What Tufvassons does

Tufvassons AB is a Swedish specialty industrial electrical distributor and in-house transformer manufacturer founded in 1938 and headquartered in Arlandastad (Sigtuna municipality), Sweden. The company operates as a wholly owned subsidiary of the publicly listed Addtech Group, a Nordic technical trading company, with which it has been affiliated since 2001. Tufvassons functions as a total supplier (totalleverantör) within electrical technology across three principal product categories: power supply (over 2,500 transformer models spanning single-phase and three-phase units from sub-kVA ratings up to 300 kVA, with multiple custom series including AVM, AFM, KGT, PVS, PVM, PFM, and STM); connection technology (connectors, cables, and cabling, including the ESCHA-sourced M12 Food & Beverage line certified to EHEDG, ECOLAB, and FDA material standards); and power quality (energy analyzers and multi-instruments, sold under exclusive Swedish agency for Germany-based Janitza's UMG-series meters plus IME Nemo MD multi-instruments, with native Modbus, Profibus, Profinet, BACnet IP, M-Bus, and SNMP communication support). All sales, design, manufacturing, and quality control are consolidated in a single Arlandastad facility.

The company goes to market through direct phone-and-email sales (no online pricing), reaching an industrial customer base in Sweden with a primary focus on industrial electrical applications and a secondary vertical in food-and-beverage hygienic environments. Pricing is bespoke and not publicly disclosed; the order intake runs through [email protected] and dedicated product-line contacts. The business model is hardware sales across its four segments (transformers, connection technology, energy-quality products, and current transformers up to 5,000 A), complemented by the Swedish agency for Janitza and the acquired IME (formerly Tälje Mätinstrument) product line integrated following the 2021 agency acquisition. Compliance footprint is anchored on RoHS, REPA producer responsibility, ISO 9001-aligned quality management via Addtech, UN Global Compact adherence, EN 61558 safety standards for transformers, and sector-specific hygienic-design certifications (EHEDG, ECOLAB, FDA) for the food-and-beverage line.

Tufvassons is privately held as Tufvassons AB, operates only within Sweden, and reports no publicly disclosed revenue figure. The Addtech Group ownership provides group-level sustainability, compliance, and capital frameworks while allowing Tufvassons to retain its independent operating identity under CEO Anders Tångring. Recent strategic activity has centered on portfolio expansion through the 2021 IME agency acquisition and the 2022 M12 Food & Beverage product launch in partnership with ESCHA, alongside the establishment of a Södertälje sales office to support instrument sales.
