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.

HVAC & Air Quality
Air Handling Unit Restoration
A spray-applied two-stage treatment for cooling coils, aluminium fins, condensation trays and AHU channels.
Materials compatibility
MS, SS, copper alloys, aluminium, PVC, EPDM and rubber seals
The operating challenge
Restore airflow. Renew indoor air quality.
Damp cooling coils trap airborne dust, lint, mineral deposits and microbial films. The resulting insulation blocks airflow, raises pressure drop and undermines indoor air quality.
Restores free airflow
Improves coil heat transfer
Clears damp odors and bio-film
Reduces fan motor drag

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
- 01Switch off the blower, isolate the coil and remove loose dust.
- 02Spray DI at 1:10–1:20 dilution and allow 20–40 minutes contact time.
- 03Rinse at low pressure and drain loosened deposits completely.
- 04Apply DF at 1:20 for 15–30 minutes, then complete a freshwater rinse.
