Red River designs and fabricates thermal energy storage vessels for data centers, power generation, biogas, and industrial process applications. Each vessel is engineered to meet ASME Section VIII, Division 1 requirements and built for thermal stability, pressure integrity, and reliable performance during continuous charge and discharge cycles. As ASME-certified pressure vessels, standard TES tanks run from 500 to 20,000 gallons nominal, in 125 or 150 PSI design pressure classes, with a 400°F design temperature and 4-inch through 12-inch CL. 150 RFSO inlet and outlet options.

Chilled water thermal storage tanks let cooling systems charge during off-peak hours and discharge stored cooling capacity during peak demand, which reduces chiller runtime and peak demand charges. The tank sits in the chilled water loop as a thermal buffer, storing cold water when the chiller runs at full output and releasing it when the chiller cycles off or transitions between states. The result is a stable supply temperature no matter how the chiller is cycling. Red River sizes each vessel from your system flow rate and desired buffer time, using the standard basis of tank volume in gallons equal to system flow rate in GPM multiplied by storage time in minutes, with 5 to 10 minutes of buffer time typical for data center and industrial loops.
Vessels sized to your chiller capacity and flow rate, from a 100-ton load at roughly 150 GPM up to 1,000 tons at roughly 1,500 GPM, with tank volume matched to the required buffer time.
Type A standard full baffle for hot and cold separation, or Type B high-perforated baffle to spread flow and reduce short-circuiting, selected per application and confirmed on the approved drawing.
Nozzle reinforcement, support attachment, and baffle design account for repeated thermal cycling across decades of service.
Coded pressure vessel fabrication with the design pressure class matched to your operating conditions. Atmospheric storage tanks that follow API 650 fall outside this Section VIII coded line.
Hot water and process heat thermal storage vessels buffer thermal energy production from thermal energy consumption in power generation, combined heat and power, and industrial process applications. Red River fabricates vessels engineered for sustained thermal service, cyclic thermal loading, and reliable long-term performance, alongside our broader range of industrial process tanks.
Biogas, oil and gas, and industrial process applications require thermal storage vessels matched to specific process fluids, operating pressures, and cycling duties. Red River fabricates custom thermal energy storage vessels, engineered for corrosive condensate service, continuous cycling, and demanding industrial environments, including dedicated support for biogas and biomethane operators.
Assessment of operating temperature range, pressure class of 125 or 150 PSI standard, storage medium, flow rate, cycling duty, and baffle arrangement before any plate is cut. In-house CFD analysis to validate tank sizing.
Carbon steel in SA-516 Grade 70, stainless steel in SA-240 304 or 316L, and clad or lined options selected based on operating conditions, water chemistry, and service life requirements. Nozzle forgings in SA-105 or SA-182 to match the shell.
All coded vessels fabricated under active ASME U Stamp certification, with a third-party Authorized Inspector engaged at required hold points and National Board registration provided when required. Standard vessels include a 14-inch by 18-inch elliptical manway with a 1-inch thick cover and a 3/4-inch NPT pressure gauge connection.
Hydrostatic testing at 1.3 times MAWP per ASME Section VIII, RT or UT non-destructive examination per code, and a complete documentation package including the ASME Form U-1 manufacturer's data report, certified mill test reports, weld records, and NDE reports.
Vessels designed specifically to handle chilled water, hot water, and process fluid thermal storage across continuous cycling service, sized from your flow rate and buffer time using the same engineering basis Red River applies to data center and industrial cooling loops.
Every coded thermal storage vessel is fabricated under active ASME Section VIII Division 1 certification with third-party Authorized Inspector engagement, and National Board registration is available on request. Verify certifications directly at asme.org and nationalboard.org.
Vessel, pipe spools, insulation provisions, and modular skid assembly, all under one quality system and one project team, built and shipped from Gillette, Wyoming, since 2003.
Pressurized TES vessels operating above 15 PSI fall under ASME Section VIII. Atmospheric tanks typically follow API 650 or AWWA D100. Red River holds active ASME U Stamp certification covering Section VIII Division 1 vessel fabrication, and its standard TES line is built in 125 or 150 PSI design pressure classes.
Red River fabricates TES vessels in carbon steel (SA-516 Grade 70) and stainless steel (SA-240 Type 304 and 316L), with nozzle forgings in SA-105 or SA-182 to match the shell. Clad or lined configurations and alloy-steel options for higher-temperature service are available, selected by operating temperature, water chemistry, and service requirements.
Yes. Red River fabricates complete modular thermal storage skid packages, pre-assembled and pre-tested at the Gillette, Wyoming facility. The tank arrives pre-piped on a structural steel skid, ready for rigging and bolt-down, which reduces field connections at installation.
Red River designs TES vessels for data center cooling loops with cyclic thermal loading accounted for in the mechanical design, including nozzle reinforcement, insulation system provisions, internal baffle selection, and support attachment design.
Every ASME-coded TES vessel is delivered with an ASME Form U-1 manufacturer’s data report, certified mill test reports, weld records, RT or UT NDE reports, and a hydrostatic test record. National Board registration documentation is included when required.
