As Italy aggressively transitions toward decarbonization, industrial processes and large-scale district heating networks require highly efficient peak-shaving solutions to manage volatile energy demands.
Nordstone stands at the forefront of Thermal Energy Storage (TES) manufacturers in Italy, delivering custom-engineered, ASME and PED-certified pressurized utility vessels that bridge the gap between energy generation and consumption.
Leveraging over 20 years of manufacturing excellence, our industrial TES pressure tanks are engineered to handle extreme thermodynamic loads, providing critical thermal stratification for hot water, chilled water, and phase-change material (PCM) systems.
By integrating advanced internal baffles and optimized nozzle configurations, Nordstone TES tanks maximize energy conservation, minimize cyclic thermal degradation, and lower operational overhead across complex HVAC, pharmaceutical, and heavy power generation frameworks.
Whether your facility requires high-capacity sensible heat storage or resilient latent heat storage systems, our Italian engineering division provides localized support backed by global compliance. Our custom solutions are built from elite carbon steels (SA516 Gr.60/70) and corrosion-resistant alloys, ensuring structural integrity under demanding industrial cycling profiles. Optimize your facility’s power management and reduce peak utility tariffs by exploring our engineering capabilities.

Industrial TES Engineering FAQ
1. What types of Thermal Energy Storage (TES) tanks does Nordstone manufacture for the Italian market?
Nordstone designs and manufactures a comprehensive portfolio of pressurized TES utility vessels. This includes Sensible Heat Systems (pressurized hot water and chilled water TES tanks) and Latent Heat Systems engineered with specialized internal structures to hold Phase-Change Materials (PCMs) for high-density energy management.
2. Do Nordstone TES vessels comply with European Union regulations?
Yes. Every thermal storage vessel destined for installation in Italy is strictly engineered and manufactured in accordance with the European Pressure Equipment Directive (PED 2014/68/EU), CE marking regulations, and international standards such as ASME Section VIII Division 1 or Division 2.
3. Why is internal thermal stratification critical, and how does Nordstone optimize it?
Thermal stratification separates hot and cold media within a single vessel based on density differences. Nordstone utilizes custom-engineered internal baffles, diffusers, and strategic nozzle positioning to maintain sharp thermoclines, preventing fluid mixing and preserving high thermal efficiency during charging and discharging cycles.
4. What materials of construction are used for Nordstone TES tanks?
Depending on the working fluid, temperature profile, and corrosive threat of the environment, we build tanks using:
- Carbon Steel: SA516 Gr. 60/70 or SA106 Gr. B nordstonein.com
- Stainless Steel: SS304/304L and SS316/316L nordstonein.com
- Specialty Alloys: Duplex, Super Duplex, and Nickel Alloys (Inconel or Hastelloy) for highly aggressive process fluids. nordstonein.com
5. What capacity ranges are available for your industrial TES pressure tanks?
Our standard manufacturing envelope ranges from 500 liters up to 50,000 liters. However, our engineering team regularly designs custom utility-grade thermal storage systems exceeding 100,000 liters for heavy industrial processing and district energy grids.
6. How do Nordstone TES systems assist Italian facilities in peak shaving?
Our TES tanks store excess thermal energy generated during off-peak periods (when electricity tariffs are low or renewable output is high). This stored energy is then discharged during peak demand hours, heavily reducing reliance on grid power and eliminating high peak utility charges.
7. What types of external insulation and surface finishes do you apply?
To minimize ambient thermal losses, we provide high-grade external insulation jackets. The raw steel undergoes automated sand/grit blasting to SA 2.5 standards, followed by the application of anti-corrosive primers, polyurethane, or epoxy topcoats tailored to withstand harsh marine or industrial environments in Italy.
8. Can Nordstone build custom coil heat exchangers inside the TES vessel?
Yes. We provide integrated internal configurations, including high-surface-area coil heat exchangers and multi-zone internal piping networks, allowing seamless heat transfer between distinct primary and secondary thermal loops without cross-contaminating fluids.
9. Which quality control metrics are enforced during the manufacturing process?
Our state-of-the-art facility conducts rigorous non-destructive testing (NDT), including:
- Radiographic Testing (RT) and Ultrasonic Testing (UT) for weld integrity
- Dye Penetrant (DPT) and Magnetic Particle Testing (MPT)
- Hydrostatic and pneumatic pressure tests nordstonein.com
- Complete material traceability backed by EN 10204 3.1 Material Test Certificates (MTC).
10. How does Nordstone support renewable energy integration like solar thermal or industrial waste heat?
Our TES pressure tanks serve as a thermal buffer. They capture irregular, intermittent energy from solar thermal arrays or recover high-temperature exhaust from industrial processes, storing it safely under pressure until it is required for secondary operations.
11. What are the typical design pressure and temperature envelopes for your vessels?
Our standard designs accommodate operating pressures from 4 bar up to 20 bar, with advanced customizations available for higher pressures. The operational temperature range spans from 0°C (for chilled water HVAC storage) up to 120°C+ for pressurized hot water and specific chemical thermal media.
12. Are Nordstone TES systems supplied as modular skid packages?
Yes. We specialize in engineering pre-assembled, factory-tested modular skid packages. This combines the TES vessel, piping manifolds, instrumentation, valves, and control systems onto a single structural frame, radically shortening on-site installation timelines in Italy.
13. What industries in Italy do you primarily serve with your thermal equipment?
Our 20 years of experience spans high-liability sectors including Oil & Gas, heavy chemical processing, pharmaceutical manufacturing, district heating and cooling networks, food processing, and defense installations requiring independent utility backups.
14. What is the expected operational lifespan of a Nordstone TES pressure vessel?
By utilizing rigorous corrosion allowances, premium alloy construction, and superior welding procedures, our vessels are designed for a mechanical lifespan exceeding 25 to 30 years under continuous cyclic thermal stress, provided standard maintenance schedules are met.
15. How do we initiate a custom design review or obtain a quotation for an Italian facility?
