Hydronic system protection
Closed-Loop Water Treatment
Testing, chemical treatment, monitoring, and maintenance for chilled-water and hot-water loops in commercial HVAC systems.
Commercial & Industrial
Protect Closed Hydronic Systems
Closed loops recirculate water, but they are not maintenance-free. Makeup water, oxygen entry, mixed metals, leaks, repairs, and depleted treatment can contribute to corrosion and deposit formation over time.
El Paso Water Tek supports chilled and hot water loops with water testing, corrosion protection programs, chemical replenishment, monitoring, and scheduled maintenance tailored to the system and facility.
Why it matters
A Practical, Serviceable Approach
Corrosion Awareness
Testing and inspection help identify conditions that may affect piping, coils, pumps, and heat-transfer surfaces.
Program Continuity
Scheduled checks help maintain treatment after water loss, repairs, additions, or operational changes.
Clear Service Records
Written observations support facility teams responsible for ongoing system operation.

Helpful answers
Frequently Asked Questions
Questions about closed-loop water treatment? Start here, then contact our team for advice specific to your water and equipment.
Why does a closed water loop need treatment?
Closed loops can still experience oxygen entry, makeup water, contamination, and chemistry changes. Treatment helps manage corrosion and deposition risks within the recirculating system.
What is the difference between open and closed HVAC water systems?
Open systems such as cooling towers interact with air and lose water through evaporation. Closed loops primarily recirculate contained water, though they still require testing and maintenance.
When should a closed loop be tested?
Testing is especially useful after installation, repairs, significant water loss, unexplained makeup, equipment changes, or when routine service indicates a change in condition.
Do you service both chilled and hot water loops?
Yes. El Paso Water Tek provides treatment support for both chilled-water and hot-water closed-loop applications.
