TEKSEA

What TEKSEA does

TekSea Sistemas de Energia is a privately-held Brazilian manufacturer of power electronics and industrial automation systems headquartered in Blumenau, Santa Catarina. The company designs, manufactures, and integrates custom-engineered equipment for critical energy applications, including thyristor and switched rectifiers/chargers, industrial UPS systems (modular, full-IGBT, SCR-IGBT hybrid), DC/AC inverters, battery management systems (Tekpower BMS), and static frequency converters for 400Hz applications. Its naval portfolio includes the Tekmation IAMCS integrated automation platform, the TEKWAS-3000 BNWAS (Bridge Navigational Watch Alarm System), fire detection, tank monitoring, and marine distribution panels. TekSea holds Type Approval certifications from ABS, DNV, Bureau Veritas, and RINA for naval equipment, making it the only Latin American manufacturer with such IACS-member certifications, which function as a regulatory barrier for international competition.

The company's business model is B2B hardware engineering with associated services—custom industrial power systems sold via quote-based multi-year contracts to enterprise customers across the energy, naval/offshore, oil & gas, telecommunications, hydroelectric, steel/mining, and transportation verticals. Confirmed end customers include Petrobras (homologated supplier), Eletrobras Furnas (30 large-scale energy systems delivered), Enel (TCA-certified for telecom infrastructure), and Agemar (fuel transport vessel automation). TekSea also distributes KRAL screw pumps and flow meters, and resells Kelvin Hughes radars, ICOM VHF radios, and ECDIS displays as complementary naval equipment. International revenue is supported through dedicated sales offices in Florida (USA) and Germany.

TekSea employs 51-100 people and operates with two factories, three commercial offices, and an R&D center supported by university partnerships. The company holds ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications from BSI Group (all recertified February 2026), and runs a wholly-owned subsidiary TekMetals for metallic enclosure production. Recent product strategy has emphasized recurring revenue via the Tekmation THOR SaaS remote-monitoring platform (launched 2025), which includes AI-based video analytics, REST API integration, and 24/7 telecom infrastructure monitoring, signaling a partial evolution from project-based hardware to hybrid hardware-plus-software commercial model.
