Your Guide For Thermal Engergy Storage Tanks
Midwest Tank Co. has been a trusted partner for tank fabrication since 1972. Our Thermal Energy Storage (TES) Tanks are custom-built to support energy-efficient cooling systems in high-demand environments like data centers, manufacturing plants, power plants, and commercial systems.
TES tanks allow facilities to store chilled water or thermal energy during off-peak hours and deploy it when demand spikes, cutting operational costs and reducing system strain. If you’re looking to improve uptime, stabilize energy loads, and support sustainable building design, a TES tank from Midwest Tank is a long-term solution that pays for itself.

Construction and Materials
TES tanks are fabricated in carbon steel or stainless steel, depending on corrosion resistance needs, budget considerations, and compatibility with the stored media. Tanks can be supplied in horizontal or vertical orientations, and interior or exterior coatings may be applied to support performance in specific operating environments. Material thickness, configuration, and finish options are selected based on the facility’s requirements and long-term service expectations.
Operational Benefits
Thermal energy storage tanks contribute to predictable cooling performance by providing a reserve of chilled water or thermal capacity. This reserve helps reduce cycling on cooling equipment, supports load balancing, and contributes to energy-efficiency goals. TES tanks also provide operational resilience by maintaining cooling availability during periods of high demand or unexpected system conditions.
