ASME Hydronic Heating Exp. Tanks

ASME EXPANSION TANKS FOR HYDRONIC HEATING SYSTEMS
ELBI’s HTS and HTL Series 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 150 psi maximum working pressure. Intended for use in hydronic heating systems, these tanks accept the expanded volume of hot water keeping the system pressure below the relief valve setting, thus preventing dangerous pressure build-up.
All models are fitted with a replaceable bladder.
