SOLUTIONS · CLOSED LOOPS
AvailableClosed loops fail quietly — until metal shows up in the filter.
AquaAdvisor tracks inhibitor reserve, corrosion regime in mixed-metal systems, glycol degradation, microbiological risk in stagnant warm loops, and makeup contamination — from the lab and controller data you already collect on the account, so the changeouts and interventions you recommend are timed, not guessed.
WHAT GOES WRONG
What goes wrong in closed loops
Inhibitor looks fine until it doesn’t
Reserve depletes with leaks, softener breakthrough, and oxygen ingress. A quarterly sample misses the slope the program is hired to catch.
Mixed metals set the real corrosion regime
Aluminum, copper, and steel in one loop need galvanic and inhibitor-chemistry context — not a single mild-steel coupon you cannot defend to the account.
Glycol degrades into corrosives
Organic acids drop pH and consume reserve alkalinity. Smell and color are late indicators — after the customer already sees metal in the filter.
Stagnant warm legs grow biology
Seasonal and standby loops sit at the wrong temperature with long residence times. Microbiological risk is chemical and operational, and it sits on the program you deliver.

Decisions enabled
What you can decide

- Which idle legs need the flush or biocide attention you specify
COMPLIANCE OVERLAYS
Relevant compliance overlays
- Link to the ASHRAE 188 programs you deliver when closed loops intersect building water management scope

AI IN THIS ASSET
AI on closed-loop chemistry
Reserve, glycol degradation, and contamination for the closed loops you treat — called from solved state, before a changeout becomes the default.
- Early flags when inhibitor reserve or glycol degradation products drift from the modeled baseline on the account
- Makeup contamination narratives that distinguish softener events and leaks from normal drift — language the field engineer can take to the site
- Top-up vs changeout recommendations bounded by the site’s metallurgy and the program specification you sell
- Stagnant warm-leg biological risk summaries with evidence attached for the account team
Model a closed loop from an account you treat.
Bring the last two lab panels and glycol type from an account you treat. We show reserve, degradation, and contamination risk in one pass.
