WTS designs and manufactures prefabricated stainless steel thermal energy storage tanks for centralized heating systems, industrial heating, cooling and energy infrastructure projects. The product range includes pressurised heating buffer tanks manufactured in accordance with PED 2014/68/EU and EN 13445, as well as atmospheric thermal energy storage tanks designed and manufactured in accordance with EN 14015.

Available in capacities from 10 to 500 m³ and designed for demanding climatic and operating conditions, the tanks are supplied as fully engineered, ready-to-use systems with high-performance thermal insulation, project-specific nozzle configurations, instrumentation provisions and a complete documentation package. By eliminating the need for custom tank design and reducing site assembly activities, WTS helps EPC contractors accelerate project delivery, lower execution risk and reduce overall installed cost.

Engineered for optimum thermal stratification, the tanks improve the performance of heat pumps, electric boilers, chillers, waste heat recovery systems and other industrial thermal processes. Thermal storage decouples energy production from energy consumption, helping operators reduce peak electrical demand, optimise equipment utilisation and improve overall plant efficiency.

Stainless steel construction eliminates internal coating requirements, provides excellent corrosion resistance and supports a design life exceeding 40 years with minimal maintenance. For EPC contractors, utilities and industrial asset owners, WTS thermal energy storage tanks offer a proven, transport-ready solution that reduces project risk, shortens delivery schedules and lowers total life-cycle cost.
