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.
