Stage I · Product DI
Descale & inhibit
PRODUCT DI uses bio-based chelators, botanical wetting agents and organic corrosion inhibitors to dissolve mineral scale, iron deposits and hardness residues without aggressive metal erosion.
All systems

Thermal Systems
Plate Heat Exchanger Restoration
Fast CIP restoration for complex corrugated plates, costly gaskets and critical HVAC heat exchangers.
Materials compatibility
Titanium, SS316, SS304, copper, brass, cast iron, EPDM, Nitrile, Viton and PVC
The operating challenge
Reopen plate channels. Renew thermal performance.
Narrow corrugated plate channels trap mineral scale, silt and bio-film. Even a thin deposit restricts flow, raises differential pressure and compromises thermal conductance.

Stage II · Product DF
Flush & neutralize
PRODUCT DF is a clarifying neutral flush that removes suspended residue, returns the circuit to a neutral pH and conditions metallic and polymer surfaces for restart.

Clean-in-place protocol
A measured path to restart
- 01Isolate the exchanger and install bypass circulation hoses.
- 02Circulate DI at 1:10–1:20 for 3–6 hours below 45°C.
- 03Drain and circulate DF at 1:20 for 30–60 minutes.
- 04Complete a freshwater rinse and safely re-engage valves.
