Taco Buffer Tanks

Buffer tanks are chilled and hot water storage vessels designed to add system fluid volume and help prevent short cycling in HVAC equipment. Their ASME Section VIII construction, vertical or horizontal configurations, internal baffle, and insulation options support hydronic heating, closed cooling, air conditioning, solar, and geothermal applications where stable operation and dependable temperature control are important.

Buffer tanks are often employed within HVAC systems to provide additional fluid volume to prevent short cycling of heating or cooling apparatus. Taco’s chilled water and hot water buffer tank line are built to last. They offer tank sizes of 50 gallons up to 3000 gallons across 22 tank volumes to meet the scope of job site-specific connection sizes specified. In addition, each model is available with system connections on the side of the tank, located either high or low, to meet application requirements.

Taco chilled and hot water buffer tanks also offer many insulation options to suit your application needs. Taco buffer tank applications include hot water heating systems, closed cooling circuits, air conditioning systems, hydronic heating & cooling, water/Glycol concentrations up to 50%, and solar/geothermal.
