WORKS LIKE A THERMAL BATTERY

OWNERS RELY ON TES TO REDUCE ENERGY COSTS AND INCREASE EFFICIENCYDN Tanks constructs prestressed concrete tanks for thermal energy

storage. Typical owners include: airports, schools and universities,

hospitals, government and military bases, power plants and private

industries. For expansion projects, owners can avoid the capital cost of

adding an additional chiller by instead utilizing a TES tank. TES is also

used as a backup for chilled water systems that require 24/7 cooling —

such as mission critical data centers.

DN TANKS ADVANTAGE• Maximum Storage Capacity: The DN Tanks specially designed diffuser

minimizes turbulence and creates a stable thermocline — effectively

stratifying the warm return and cold supply water within the tank.

• Unparalleled Reliability: DN Tanks prestressed concrete tanks are

designed and constructed to perform reliably for decades. In fact,

every one of the TES tanks we’ve ever built is still in service today.

• Lower Cost of Ownership: A DN Tanks prestressed concrete tank will

last for generations — with no scheduled maintenance. This makes it

a superior choice for long-term value and cost of ownership.

• Construction Flexibility: Because of inherent characteristics of

concrete, the TES tank can be partially or fully buried underground.
