The nature of closed loop systems is such that very little water is used as
makeup and hence corrosion and microfouling are the potential problems.
Corrosion can be pitting, galvanic and/or crevice attack. Inhibitors
typically used are nitrates, molybdates for effective control
Microbiological fouling is due to iron reducing bacteria, nitrifying
bacteria and pseudomonas slime forming bacteria. These foulants reduce sysem
efficiency and increase operating and maintenance costs. We have extensive
experience of protecting and treating close loop circuits.
For HVAC applications Initial flushing, cleaning and passivation of the
chilled water circuits is a very important activity to maintain long term
health of the system. Most large chilled water HVAC systems can never be
stopped once operational. Careful initial flushing and passivation can
protect the system for a long time and can give trouble free services.
We has following solution for Close loop system.
