In our latest video, Goodway Technologies demonstrates a Clean-in-Place (CIP) chemical descaling process performed on a Hexonic plate heat exchanger using their GDS system. This method provides an effective solution for restoring performance without the need to dismantle the unit.
Maintaining the efficiency of plate heat exchangers is critical for ensuring optimal system performance, minimizing energy consumption, and avoiding costly downtime. Over time, however, scale buildup and fouling can significantly reduce heat transfer efficiency and increase pressure drop — clear indicators that maintenance is required.
Why Clean-in-Place (CIP)?
CIP is a highly efficient maintenance approach that allows operators to clean heat exchangers while they remain installed in the system. This not only reduces labor requirements but also significantly shortens downtime.
Key benefits of the process include:
🟧 Recovery of full heat transfer efficiency
🟧 Reduction of pressure drop across the unit
🟧 Removal of scale without disassembly
🟧 Minimal downtime — typically just 2–4 hours
How the Process Works
The demonstrated cleaning process uses controlled chemical circulation through the heat exchanger. Key features of the system include bottom-to-top flow, effective foam and CO₂ management, and flow-reversal capability. These elements ensure that even partially blocked channels can be thoroughly cleaned.
As a result, the heat exchanger can be restored close to its original design performance.
When Should You Clean Your Heat Exchanger?
There are a few clear warning signs that indicate it’s time for maintenance:
-
Increased pressure drop (ΔP)
-
Approximately 30% loss in heat transfer efficiency
-
Reduced system performance or higher energy consumption
Ignoring these signals can lead to further efficiency losses and potentially more serious operational issues.
Watch the Process in Action
The full step-by-step cleaning process is shown in the video, offering a practical look at how CIP can be applied in real operating conditions.
Regular maintenance, supported by the right technology and expertise, ensures long-term reliability and performance. Thanks to the collaboration with Goodway Technologies, customers can implement proven solutions that keep their systems running at peak efficiency.
