Thermal Energy Storage Systems
Universally recognized and accepted, Thermal Energy Storage (TES) has enabled facilities requiring chilled water-cooling to significantly decrease costs while maintaining desired service levels. Chilled water or ice is produced during off-peak hours and stored in an insulated tank. Electrical costs peak during the day when demand is at its highest and are significantly less during evening hours, when demand decreases. TES allows you to produce ice or chilled water during off-peak hours, store it in an insulated tank, and use it to cool your facility during peak hours.
Advantages to 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 or chilled 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. In addition, Caldwell’s steel tank construction provides low maintenance and reliable service unlike competitive concrete tanks, which can crack and may experience significant water loss.
Optional Fire Protection Advantages
TES tanks are full at all times, availing 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.
Caldwell is established to better serve the growing demand for thermal energy source systems and environmental products.
An industry leader, Caldwell and its engineers work with advanced computer technology to offer complete design/build capabilities for new systems or expansions utilizing TES. Services include system evaluation, chiller and pumping modifications, tank design and construction, and developing the control logic and valves, necessary to operate the system most efficiently. Caldwell utilizes state-of-the-art cutting, forming and welding equipment to satisfy fabrication requirements. Highly skilled, safety and quality conscious construction personnel are the final ingredient to a turn-key operation which is known for on-time, on-budget, quality performance.
