Product Series Description

Our DTS and DTL Series Thermal Expansion Tanks are designed according to the ASME CODE Section VIII – Div. 1 using the latest technology in terms of manufacturing processes and quality control. Available in standard 150 psi maximum working pressure. Intended for use in commercial and industrial domestic potable hot water applications, these tanks accept the expanded volume of hot water keeping the system pressure below the relief valve setting, thus preventing dangerous pressure build-up.
