Product Description

ASME U Stamped HP Evaporator Shell & Tube Heat Exchanger for Geothermal ORC Duty

This is a heavy-duty HP (High-Pressure) Evaporator engineered for a 28 MW geothermal Organic Rankine Cycle (ORC) power plant. The unit transfers heat from geothermal brine to the organic working fluid n-Butane C.G. on the shell side, vaporizing it ahead of the turbine. The exchanger is ASME Section VIII Div.1 + TEMA coded and ASME U-Stamp certified, designed for high-pressure, high-temperature geothermal service with full corrosion allowance on both sides.

We installed this heat exchanger at our petrochemical facility in Jubail Industrial City back in March. The ASME VIII-1 certification was non-negotiable for us, and this unit delivered exactly what we needed. The SA516 Gr485 shell material has held up exceptionally well against our high-temperature process streams, even during the peak summer months when ambient temperatures exceed 45°C. What impressed me most was the quality of the welding—our inspection team did radiography testing on random seams, and all passed with flying colors. The supplier kept us updated throughout fabrication with photos and progress reports, which built a lot of trust. We've had zero leaks or performance issues since startup. Definitely planning to order another unit for our expansion project next year.

The SA516 Gr485 material is known for its low-temperature toughness, and the vendor confirmed the impact testing met our specifications. Shipping to a remote location is always challenging, but the crating was heavy-duty and protected the unit during the long truck haul.

Even in our tropical heat, the heat transfer rate is exactly as promised. The shipping crate was very sturdy, arriving with no fins bent.
