Closed Loop

Efficiency Begins From Within

The Closed Loop Treatment Program uses field-proven products and services that protect components from corrosion, improve system performance, save on energy consumption, and reduce GHG emissions.

What is a Closed Loop System?

Closed Loop heating and chilled water systems circulate water through a piping system intended to heat and cool a building. “Closed Loop” implies the recirculation of the same water, typically requiring little to no makeup water following the initial system charge. 

However, even small unexpected water leaks can introduce corrosive elements, such as oxygen, that degrade these systems.

Problems in Closed Loop Systems

Corrosion, scale, fouling and microbiological growth are considered the four major problems in all types of circulating water systems. In Closed Loop systems, corrosion stands out due to the introduction of dissolved oxygen from the raw water makeup. 

Dissolved oxygen causes mild steel and iron to corrode rapidly, releasing small flakes of rust into the recirculating stream. Abrasive particles erode pump seals, cause leakage, reduce heat transfer efficiency and block pipes. The result is expensive equipment replacement and excessive downtime.

Closed Loop System Solutions

The Closed Loop Treatment Program is designed to economically improve operations while decreasing the carbon footprint. We identify and eliminate the source(s) of significant water loss, protect system components from corrosion, improve heat transfer efficiency, save on energy consumption, and cut GHG emissions. 

The program includes our on-site testing services, e-Service Reporting, and implementing a film-forming corrosion inhibition treatment that provides excellent corrosion rate protection as recommended by the Association of Water Technologies (AWT).

The Closed Loop Treatment Program works in tandem with our energy saving program, EndoTherm®, to reduce the surface tension of the system water, increase heat transfer, optimize energy gains and lower fuel cost/usage.
