ALSTOM Generator Air-to-Water Cooler Replacement Manufacturer

Our Replacement Solutions for ALSTOM Generator/Motor Heat Exchangers

1. Direct OEM-Equivalent Designs

We manufacture replacement heat exchangers that are dimensionally and hydraulically interchangeable with ALSTOM models.

• Same mounting positions

• Same nozzle orientation

• Identical footprint and tube bundle configuration

• No modifications required during installation

This ensures a seamless replacement during planned or emergency maintenance.

2. High-Efficiency Cooling Performance

Our replacement coolers are designed to maintain the required thermal performance for safe generator and motor operation. Options include:

• Air-to-water coolers

• Closed-loop water coolers

• Tube-fin air coolers

• Shell-and-tube heat exchangers

We match or exceed the heat transfer capability of original ALSTOM units.

3. Heavy-Duty Construction Materials

To maximize service life, we provide upgraded material options based on site conditions:

• Copper, copper-nickel, or stainless steel tubes

• Epoxy-coated carbon steel shells

• Aluminum or copper fins for air coolers

• Corrosion-resistant tube sheets
  These materials help reduce fouling, erosion, and corrosion—common failure points in aging ALSTOM coolers.

4. Custom Manufacturing for Any ALSTOM Model

We can reverse-engineer and rebuild heat exchangers from drawings, samples, model numbers, or damaged units.
Typical replacements include:

• Generator air-to-water coolers

• Motor closed-loop coolers

• Hydrogen-cooled generator heat exchangers

• Stator water cooler bundles

Even if the original ALSTOM model is discontinued, we can supply a fully compatible replacement.

5. Fast Delivery for Power Plants & Industrial Users

Unplanned outages caused by failed coolers can be costly. We offer:

• Priority production for urgent replacements

• Pre-assembly and pressure testing

• Worldwide shipping
  Our team ensures minimal downtime for your ALSTOM generator or motor.
