External Shell-and-Tube Heat Exchanger Technology by Ecotherm (Water or Steam Operated)

Ecotherm is globally recognized for its turnkey solutions in hot water, steam, and solar energy systems for hotels, hospitals, and industrial applications. With extensive experience and a team of highly skilled engineers, Ecotherm has developed exclusive technologies unique to the brand.

One of its most innovative solutions is the external shell & tube heat exchanger technology, operated by either water or steam.

High-Capacity Hot Water Tank Technology “EHRE” by Ecotherm (Austria)

Industrial Hot Water Tanks – EHRE & EDRE Models

This technology is applied in Ecotherm’s high-capacity commercial hot water tank models EHRE and EDRE. These systems, operating with steam or hot water, are widely used in:

• Hospitals
• Hotels (laundry systems)
• Industrial applications

Thanks to the high energy content of steam, these systems can deliver maximum hot water output while requiring minimal floor space—saving up to 95% of installation space compared to conventional designs.

This advantage makes the technology a preferred choice for investors and contractors in large-scale projects.

Advantages of External Shell & Tube Heat Exchanger Technology

The external shell & tube heat exchanger system includes:

• High-performance insulation layer made of sheep wool, with patented aluminum sealing strips
• External heat exchanger tubes equipped with patented free-floating turbulator rods

This heat exchanger design is considered one of the most advanced solutions available today.

Key Benefits:

• High heat transfer efficiency
  The internal turbulator rods create strong turbulence and high flow velocity, significantly improving heat transfer performance and reducing energy consumption.
• Self-cleaning and anti-scaling capability
  The system minimizes lime scale and fouling through a self-cleaning mechanism using free-floating turbulator rods made of high-quality Duplex AISI 316Ti stainless steel.

• Advanced insulation system
  The storage tank is insulated with sheep wool material and a durable PP outer casing (RAL 7037), featuring patented aluminum sealing and a self-locking cover for quick installation.
  • Insulation thickness:
    • 80 mm (up to 1,000 liters)
    • Over 100 mm (larger capacities)
  • 100% recyclable
  • Fire resistance class B2 (B1 upon request)

This insulation system can reduce heat loss by up to 30%, significantly improving overall system efficiency.

Conclusion

With thousands of installations across Europe, the Middle East, Asia, North Africa, and Central America, ECOTHERM has built a strong reputation with its concept of “tailor-made heat transfer solutions”—delivering high-quality systems, innovative products, and premium services from design to implementation.
