The Challenge
- Industrial water heater limescale fouled three ageing heaters supplying apple washing
- Scale accumulated on heater tubes and tank walls
- Scale created extensive maintenance requirements
- Heater reliability and efficiency were affected
- The equipment was nearing the end of its expected life
The Solution
One HydroFLOW® unit was installed in an apple packing facility on the incoming water line feeding the three heaters in 2011. When those heaters were replaced with high-efficiency models in late 2025, the facility upgraded to a Generation 4 HydroFLOW® i60 in January 2026, with a HydroKNCT device linked to Hydropath Care remote monitoring software. Six HydroFLOW® units have been used across the facility over 15 years. Scale on the heater tubes and tank walls fell by over 70% within three months, and a heater bank that was already near the end of its expected life went on running for another 14 years.
