Tank One Thermal Expansion Tanks Tank One

Kofulso offers Tank One thermal expansion tanks in two sizes: 2.1 gallons and 4.5 gallons. These tanks are equipped with a butyl rubber diaphragm and plastic liner that separates the system water from the tank’s air charge. The system connection features a stainless steel nipple to prevent corrosion. Moreover, the tank’s shell is coated with a high-quality material that effectively prevents external corrosion. Each Tank One thermal expansion tank is rigorously tested and comes with an Kofulso 5-year limited warranty.
