Heat exchangers are critical components in marine vessels, power plants, refineries, chemical facilities, and a variety of industrial processes requiring precise thermal regulation. These systems are used for heating or cooling water, oil, air, refrigerants, and various fluids.
Depending on their function and construction, heat exchangers are categorized into:
- By application: air coolers, oil coolers, water coolers, condensers, evaporators, refrigeration coolers, etc.
- By construction: tube-type coolers and plate-type coolers
Typical issues affecting heat exchangers include:
- Clogging of tubes due to mineral deposits
- Corrosion on tubes or plates leading to leakages
- Erosion or pitting on cooler covers caused by vibration and fluid impact
At YAF Engineering, we offer comprehensive services for both tube-type and plate-type coolers to ensure long-term performance, safety, and efficiency.
