Universally Recognized and Accepted
Thermal Energy Storage (TES) has become a powerful asset for chilled water-cooling — enabling facilities to significantly decrease costs while maintaining desired service levels.
Cool or Heat Your Facility During Peak Hours — for a Fraction of the Cost
Facilities produce chilled water or ice during off-peak hours, storing the product in an insulated tank. Consider that electrical costs peak during the day, which reflects when demand is at its highest. During evening hours, demand decreases, leading to less electrical expenses.
The TES advantage: Leveraging TES allows you to produce ice or chilled water during off-peak hours, store it in an insulated tank, and use it to cool or heat your facility during peak hours. Commonly seen in district energy and university central heat plants, Caldwell provides custom solutions to match your custom energy needs.
5 Key Benefits to Using Thermal Energy Storage
Lower Energy Costs and Incentive Savings
Compared to conventional cooling with chillers, TES provides lower energy costs and incentive savings. By producing ice, chilled, or hot water during off-peak hours, you save on utility rates and demand charges. Many utilities also offer cash incentives and rebates for installing or converting to TES.
Lower Capital Outlays
TES Tanks allow a reduction of chiller capacity. This is true for both new construction and system expansions.
Lower Maintenance Costs and Requirements
Less equipment translates to reduced maintenance needs. Additionally, Caldwell’s steel tank construction provides low maintenance with reliable service.
Optional Fire Protection Advantages
TES tanks are full at all times, ready to offer a massive supply of water in case of fire. Caldwell engineers can design a tank to fulfill the dual service of cooling and fire protection.
Environmental Advantages
Many coolants and refrigerants face potential bans due to environmental concerns. Chilled water can be produced efficiently, employing any cooling technology available today or in the future.
