Kolektor Sisteh

What Kolektor Sisteh does

Kolektor Sisteh d.o.o. is a Slovenian systems integrator and engineering services provider established in 1992 and operating as part of Kolektor Group's Kolektor Technologies division. The company delivers comprehensive technological solutions across three core areas: industrial automation and electrical engineering, low-voltage power supply (including UPS and backup power), and water treatment technologies. It serves industrial enterprises, municipal water utilities, and energy-sector customers in Slovenia and adjacent Central and Southeast European markets, with named reference clients including the Slovenian Ministry of Defence (MORS), Istrski vodovod, Marjetica Koper, Kansai Helios, K2PAK, Livar, ETI, and Šoštanj Thermal Power Plant.

The company's technical capabilities span the full project lifecycle, from consulting and feasibility engineering through equipment supply, system integration, and post-project service and maintenance. It distributes and integrates equipment from global OEMs including Eaton, Advantech, Stahl, Wieland, HUBER, Bermad, Prominent, GEMÜ, A.R.I., and DOLD, and combines these with proprietary offerings such as the Sinapro paperless production platform, custom I/O modules for SMC and Festo valve islands, and IoT infrastructure for battery energy storage systems (BESS). Over approximately 30 years of operation, the company reports successful completion of more than 5,000 projects.

Revenue is generated through three principal streams: professional engineering and integration services for industry, energy, and water projects; distribution of electrical and technological equipment; and managed technical support and maintenance services. Go-to-market is direct sales-led, organized by product specialization (Digitalization and Control Systems, Energy Systems, Electrical Equipment, UPS/DEA, Water Treatment Technologies, and Service) with headquarters in Ljubljana-Črnuče and additional offices in Idrija and Maribor in Slovenia, plus regional offices in Zagreb (Croatia) and Beograd (Serbia). A B2B e-commerce storefront for electrical equipment was launched in March 2026, supplementing the project-based direct sales motion. Pricing is project-based with customized quotes and is not publicly disclosed.
