Lochinvar now offers Lock-Temp stainless-steel storage tanks in three new models with 60-, 80- and 119-gal. capacities. The new units extend the offering of the Lock-Temp tank family, which includes glass- and cement-lined storage tanks with capacities ranging from 60 gal. to 5,000 gal. The tank is a fully welded and passivated stainless-steel storage tank for potable water. The vertical tank is wrapped in a dent-resistant polypropylene jacket and insulated with expanded foam that exceeds the ASHRAE 90.1 requirements for standby heat loss. Lochinvar backs the tanks with a 10-year limited warranty.
