Expansion Tanks

Compression, Bladder and Diaphragm. Each tank style has models that are either ASME or Non-ASME coded. Tanks range in size from 2 to 10,000 gallons. Most of Wessels pressure vessels are designed using a pre-pressurized vessel with an internal bladder or diaphragm to manage fluids under pressure. The majority of Wessels products are standard catalogue models, with over 6,000 tanks in inventory for immediate shipment. Custom tanks are produced to customer specifications, for high pressures and/or special materials for severe duty applications.

expansion tank bladder tank

Bladder Tanks

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.
