Closed Loop Water Treatment
Closed Loop Water Heating & Cooling Systems
Closed loop heating and cooling systems are commonly used since they meet a facility’s heat transfer needs while minimizing water consumption from evaporative loss. Since they often provide heat transfer for critical manufacturing or process equipment, it’s vital they run efficiently. Preventing fouling and corrosion with proper treatment chemical dosing is the most important factor for helping the cooling system do its job efficiently and extending the life of the equipment.

Closed Loop Preventative Maintenance Service Plans
We start with an analysis of the closed loop’s function within the facility, evaluate system condition and water chemistry before recommending a comprehensive industrial Water Management Program. A preventative maintenance plan for your closed loop system will target dissolved solids, balance pH, and remove oxygen from the water. EAI Water will monitor closed loop equipment and water chemistry to prevent foulants and corrosion from raising utility costs, while extending the life of cooling equipment.
Low Dose Closed Loop Water Treatment Chemicals
EAI Water offers a full line of custom formulated chemicals designed for low doses, saving costs while minimizing our ecological footprint. We have an array of blends specialized for the operating demands of closed loop systems. While closed loop equipment may be at lower risk than open systems, small amounts of biological growth within a closed loop system can quickly grow and form a biofilm on interior surfaces. Our chemistry options find the right mix of nitrite and molybdate-based blends to inhibit corrosion while balancing biological growth and discharge considerations.
Water Treatment Service Plans Offer:
- Onsite water analysis
- Custom blended chemicals added
- Calibrate conductivity and water quality sensors
- Program controllers and chemical pumps
- Remote daily monitoring
- Legionella testing
- Filter replacement
- Ultraviolet monitoring
- Written service reports after each visit tracking program KPIs over time
Remote Monitoring for Closed Loop Systems
Production downtime is sometimes unavoidable, but never has to be the result of fouling due to heating or cooling system maintenance. Problems resulting from water temperature, pressure, leaks and chemical dosing are not inevitable. A remote monitoring system calibrated by EAI Water will ensure production is never compromised and productivity is always up. We offer training and support so that every alert receives the right response.
Plan to Avoid Closed Loop Equipment Fouling
Relying on a closed loop system’s water saving ability may provide some peace of mind against feedwater contaminants, but there is still plenty of opportunity for bacteria, iron and biofilm to form. While the risk of scale may be lower in a closed loop system, a fraction of an inch caused by minerals and hardness, can form deposits that increase operational costs. Without the blow down function to release contaminants, foulants have no escape. Iron oxide gains momentum, eventually turning to an organic acid that corrodes metal, shortening the life of equipment.
