Tube-sheet and waterbox damage is caused by galvanic corrosion and cavitation; poor water treatment can accelerate this process but eventual failure is imminent.
If the damage is not prevented (new chillers) or addressed (existing chillers) it will lead to water invasion of the refrigerant circuit and cause catastrophic equipment failure.
Corrosion will also affect water boxes causing leaks and allowing water to bypass the divider plate resulting in capacity loss.
Examples of tubesheet failure are visible after corrosion is removed:
Our proprietary process of ceramic coating completely encapsulates and insulates the tubesheet and waterboxes from water contact stopping the corrosion process and it is cavitation resistant.
Benefits of Our Coating Process
Prevents bimetallic galvanic corrosion between the tube and the plate
Prevents the entry of cooling liquid into the process side, and vice versa
Prevents water leaks from water boxes
Prevents divider plate damage and water bypass
Facilitates the inflow of water by reducing friction
Reduces the accumulation of debris on the face of the tubesheet that can obstruct tubes
Reduces fouling and turbulence
Improves overall chiller efficiency
