Its portfolio covers industrial burners (including Low NOx and JBD-series duoblock designs), industrial boilers (steam, hot water, water-tube, fire-tube, biomass), and proprietary complementary modules branded as SICAPH combustion air preheaters and Nirafon acoustic cleaning systems, alongside Flue Gas Recirculation (FGR) systems, Regenerative Thermal Oxidizers (RTO), and containerized or mobile boiler rooms. The business is organized around five revenue streams: one-time turnkey engineering and supply projects, recurring maintenance and regulatory inspection contracts, hardware and spare parts sales, repair and revamping professional services, and a managed technology renting model for thermal plants.

The company serves a diverse set of enterprise industrial verticals, including food and beverage, paper and cardboard, pharmaceutical, chemical and petrochemical, automotive, beverages, and power generation. Named customers include Repsol, Iberdrola, Pemex, Gerdau, Gestamp, Peugeot, Saudi Electricity Company, Abengoa, Initec Energía, Puleva, Lactogal, Koipe, and La Casera, among more than 35 client logos. Go-to-market is direct enterprise field sales, with project-based, consultative engagement from feasibility study through handover and post-sale maintenance. While the home market is Spain, the firm documents on-site commissioning and maintenance deployments in Saudi Arabia, Morocco, Indonesia, Israel, and China, typically feeding into larger EPC consortia led by partners such as Initec Energía (ACS Group) and Abengoa. The company holds ISO 9001 and ISO 14001 certifications, has no disclosed external funding, and is led by CEO Raúl Cabadas.
