Case Study from HydroFLOW USA

Multi site scale control across a retail chain

Multi site scale control was needed by a US convenience store chain with the same problem at every location: scale in water heaters, fixtures and food service equipment, and biofilm and scale in the ice machines. Frequent cleaning and descaling meant maintenance costs were multiplied across the estate. HydroFLOW® S38 and HS40 units were installed on the water heaters, ice machines and food service equipment, and rolled out across more than 30 stores. Residue now stays powdery and rinses away rather than sticking, and cleaning and descaling are needed less often. The same small, standard installation went into every store.

The Challenge

  • Multi site scale control was needed for heaters, fixtures and equipment in every store
  • Frequent cleaning and descaling was required
  • Biofilm and scale were accumulating in ice machines
  • Maintenance costs were repeated at every location
  • The chain wanted one standard installation it could repeat

The Solution

  • Units installed: HydroFLOW® S38 and HS40
  • Installation point: water heaters, ice machines and food service equipment
  • System: more than 30 convenience stores, with the same kit at each

The chain treated multi site scale control as a standard fit rather than a site-by-site project. Each store took the same short installation on the same three pieces of equipment, so the chain’s maintenance contractor could fit the units on a normal service visit. The signal disrupts the conditions that bond scale to surfaces, so residue stays powdery and rinses away.

Key Outcomes

R

Hard scale visibly reduced on fixtures and equipment

R

Scale and biofilm accumulation reduced

R

Heating elements and fixtures remained cleaner

R

Return on investment within 6–12 months

Independent Verification

All results in this study were measured and verified by third-party facilities managers and technical staff.

Summary

More than 30 stores now run the same kit, with residue that rinses away rather than bonding and less frequent cleaning and descaling. Retail chains buy on repeatability. A kit small enough to fit in every store, giving the same result at each one, is what made this a rollout rather than a trial, and the maintenance saving compounds at every site.
