Closed Loop

Typically used in district heating and chilled cooling, “closed loop system” are effectively sealed and the water inside is not exposed to the atmosphere. Closed loop systems contain a fixed volume of water that recirculates and tends to suffer only negligible water losses but needs monitoring for potential corrosion, deteriation and cleanness.

As a convenient way of heating or cooling building services applications and industrial and commercial processes. But without effective water treatment corrosion products, foulants can build up impairing flow and heat transfer and control valves can become blocked and inoperative. At Sensys Ltd we provide industry-leading sensors to monitor closed circuit water systems, preventing inefficiencies caused by corrosion, foulants, and valve issues.
