MAINTAIN PERFORMANCE WITHOUT OPENING YOUR PLATE HEAT EXCHANGER
Automatic Plate Heat Exchanger Backflushing
EQOFLUSH is an automatic plate heat exchanger backflushing system that removes fouling by reversing flow — reducing manual cleaning and operational downtime.
- Reduces manual cleaning frequency
- Minimizes downtime and operational disruption
- Suitable for retrofit and new systems
- Maintains flow distribution and heat transfer performance
Applied in industrial plants and data center cooling systems — including free cooling applications.
Impacting uptime, efficiency, and cooling strategy:
Fouling in Plate Heat Exchangers Leads to Performance Loss and Frequent Cleaning
Plate heat exchangers gradually foul during operation.
As deposits build up, heat transfer efficiency decreases and pressure drop increases — making periodic cleaning unavoidable.
- Reduced heat transfer performance
- Increased pressure drop across the exchange
- Unplanned or frequent maintenance intervals
- Cleaning requires shutdown, dismantling and gasket replacement
Reduce the need for frequent shutdown and dismantling.:
Clean Without Opening the Heat Exchanger
EQOFLUSH removes fouling by periodically reversing the flow through the plate heat exchanger.
This disrupts and loosens accumulated deposits — restoring flow distribution and heat transfer performance.
During operation:
- Flow direction is periodically reversed
- Deposits are dislodged from plate surfaces
- Fouling is flushed out of the exchanger
By maintaining performance through plate heat exchanger backflushing, systems such as free cooling loops can operate more effectively over time.
How It Works: Flow Reversal Cleaning During Operation
- In plate heat exchangers, fouling typically accumulates where flow enters the plate channels and in low-velocity zones within the corrugation pattern.
- By periodically reversing flow direction, these deposits are dislodged from the plate surfaces and carried out of the exchanger.
- Deposits that would otherwise remain until the next manual cleaning are washed away (to the cooling tower basin).
This process takes place over short intervals, without interrupting normal system operation.
For new installations and retrofits across all plate heat exchanger types:
Flow Reversal Valve Selection Depends on Your System Layout
Different piping layouts and operating conditions require different flow reversal valve designs.
We offer a range of valve configurations to ensure reliable operation and optimal cleaning performance.
- Layout Compatibility
Valve selection depends on available space, pipe routing, and how the system is integrated into existing infrastructure, ranging from DN50-DN700 - Cross-Over Control
Different valve designs allow varying levels of cross-over control, down to minimal levels required for stable operation. - System Reliability
A properly selected and engineered valve ensures consistent performance without complex synchronization or control risks.
Each system requires a tailored approach.
Our engineering team assists in valve selection for your automatic backflushing system based on your specific layout and operating conditions.

When is backflushing the right solution?
Plate Heat Exchanger Backflushing is particularly effective in systems where fouling builds up gradually and cleaning requires frequent heat exchanger maintenance shutdowns.
Typical indicators include increasing pressure drop across the plate heat exchanger, reduced heat transfer performance, and recurring manual cleaning intervals.
In these situations, an automatic backflushing system can restore flow distribution and delay fouling buildup — without interrupting operation.
EQOFLUSH is especially suitable for systems with variable load, open water circuits, or applications where uptime is critical and manual intervention is costly.
