Thermal Energy Storage (TES) is a key element in delaying the effects of cooling failure due to power loss or catastrophic failure. TES systems are engineered process tanks or vessels that add heat or remove heat from a storage medium such as water. TES is a low cost form of storage that can be either a pressurized ASME vessel or atmospheric UL-142 storage tank. The fundamental process of TES is a basic concept. Water is cooled by chillers during off-peak hours and stored in insulated tanks. This stored, cooled water is then used for space conditioning during times of high temperatures using pumps, control valves and fan energy. The most common chilled water TES is a cylindrical, vertical pressurized water storage vessel. These rugged steel vessels are protected from corrosion with durable interior and exterior polyurethane coatings.

Environmental benefits include reduction of source energy use, decreased refrigerant charge and improved efficiency of the energy supply. Because Highland Tank's TES are made of durable goods like protected steel, non-corrosive PVC diffusers and minimal, if any, VOC coatings, life cycle costs are at a minimum.
