About CTC
CTC AB is a Swedish manufacturer of heating and thermal technology based in Ljungby in the province of Småland. Founded in 1923 in Gothenburg, the company develops and produces ground-source heat pumps, air/water heat pumps, hot water heat pumps, oil and gas condensing boilers, oil and gas forced-air burners, indoor modules, storage tanks, solar heating systems and control systems. The complete value chain from development through design to manufacturing takes place in Ljungby. Materials processed include steel, enamelled steel, stainless steel, copper, brass and aluminium as well as injection-moulded polyurethane (PUR) for the insulation of the storage tanks. The products are designed for Nordic climate conditions and serve heating, hot water generation and cooling in single-family homes and larger buildings. CTC belongs to Enertech AB, whose brands also include Bentone and Turboflame, and distributes its products through a dealer network in Germany, Switzerland and worldwide, among other markets.
