Đuro Đaković Energy d.o.o.

What Đuro Đaković Energy d.o.o. does

Đuro Đaković Energy d.o.o. is a Croatian industrial equipment manufacturer specializing in custom-engineered steam, hot oil (thermal fluid), hot water, and biomass boilers, alongside pressure vessels, heat exchangers, containerized boiler rooms, and tube coils. Founded in 2021 as a new entity that absorbed the boiler production operations of Đuro Đaković Kotlovi, the company operates from Slavonski Brod and continues a boiler production tradition in the city dating to 1926. Production capabilities span plasma cutting (up to 2,500 x 6,000 mm), sheet and plate bending (up to 25 mm thickness, 3 m width), mandrel and non-mandrel pipe bending (up to 76.1 mm diameter), and welding certified to ISO 3834-2 and the EU Pressure Equipment Directive (PED 2014/68/EU), with documented WPQR coverage for procedures 111, 121, 135, 136, 141, and 311. Boiler offerings range from low-pressure units (e.g., NPK 1000 at 0.5 bar) to high-capacity installations (e.g., three TMIS 7.5 units at 5,000 kW each delivered to the Netherlands).

The company serves a B2B industrial customer base across healthcare (e.g., Županijska bolnica Čakovec, Dom za starije i nemoćne osobe Zadar), food and beverage brewing (Osječka pivovara), construction (Kamgrad, Termoelektro Brčko), manufacturing (Kaufland, Knauf Insulation, Chips Way, Europat 2005, BIM a.d.), and oil and gas (INA well-rehabilitation cofferdams), with after-sales servicing and rehabilitation supporting a recurring service stream. Revenue is generated through project-based, custom-quoted hardware sales, integrated engineering and design services, and maintenance contracts, with pricing handled through direct sales contacts and quote request forms rather than published tiers. Go-to-market is direct enterprise sales, supplemented by strategic partnerships (notably with Slovenian firm Miel Inženjiring for Western European deliveries), industry event sponsorship (e.g., 12th Sawmill Congress JIE), and a multilingual website with social media presence on LinkedIn, Facebook, and YouTube.

Geographic reach at the time of input covers Croatia as the domestic base plus export deliveries to Bosnia and Herzegovina, Serbia, Bulgaria, North Macedonia, the Netherlands, and Cyprus, with no distributor or reseller network. The firm is a privately held Croatian d.o.o. with no disclosed parent company, institutional investors, or external funding. As of source data (2023), stated headcount is 9, though individual projects have engaged more than 30 personnel, suggesting a flexible contractor/subcontractor model for larger orders.
