What TTO Thermotechnik d.o.o. does

TTO Thermotechnik d.o.o. is a privately held Croatian OEM manufacturer of components and equipment for hot water heating and cooling systems, headquartered in Dražice, Croatia. The company designs and produces hydraulic manifolds (distributors), regulation technology (thermoelectric drives and regulation bases), hot water substations for decentralized thermal energy supply in multi-residential buildings, and complementary distribution cabinets and underfloor heating accessories. Its proprietary TTO-Adaptto technology provides adaptive heating regulation for precise temperature control, and the company runs an in-house R&D department with more than 25 years of product development experience. The firm is ISO 9001 certified and operates from a manufacturing facility expanded in 2016 with an investment of approximately 21 million HRK.

The company sells on a B2B basis to three primary customer segments: residential and multi-apartment building projects requiring centralized heating distribution, industrial heating installations needing customized solutions, and tradespeople/installers served through a dedicated TTO Partner network. It also supplies OEM production to heating system manufacturers. Revenue mechanics are driven by ex-works, quote-based pricing on manufactured equipment rather than software licensing or recurring contracts, and the company has historically focused on the Croatian market while initiating a publicly funded internationalization push into Germany, Austria, and Italy anchored by participation in ISH Frankfurt 2027. The company is led by CEO Radisav Drljević, employs 51-100 people, and carries a fully paid share capital of EUR 422,520.

The go-to-market motion is enterprise field sales supplemented by the TTO Partner channel program, with limited digital marketing and no direct-to-consumer distribution. Marketing presence is concentrated in a multilingual corporate website (Croatian, English, German), trade fair participation, and EU project visibility. The company has received modest EU co-financing (NextGenerationEU and structural funds) to support digital maturity and internationalization initiatives.
