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.
