Glycol solutions are frequently used to fill closed systems. Uninhibited glycol is very corrosive to system metals, so the glycol fluids being used must be inhibited with the appropriate corrosion inhibitors. Chem-Aqua recommends that only inhibited glycol fluids be used in these systems.

In a water-based HVAC system, a cooling tower is typically combined with a water-cooled chiller for the purpose of rejecting excess heat from the system. Chardon Labs offers an array of chemical treatment solutions that include highly effective corrosion and scale inhibitors for hard make-up water, as well as soft or low TDS make-up water.

out through a heat exchanger to another water loop or air. Closed loop heating systems have heat added to the loop, and the heat is then removed from the water by a heat exchanger into another water loop or into air. Some closed loop water systems include chilled water, engine jacket cooling, brine water systems, compressor cooling, hot water heating, power supply cooling, and other industrial processes.

Molybdate and Non-Molybdate Options for Closed Systems

Closed recirculating systems or closed hydronic loops utilize a water-based solution to transfer heat. The most common distinction defining a closed system is the fact that the method of cooling is non-evaporative. Minimal water loss/makeup requirement and minimal air contact are two additional conditions typically associated with closed loops.

Chiller water treatments should be a must for most chiller plants… where the pipes are made up low carbon steel and normal water is used as the make-up water. Statistics say that for a 1,000 ton chiller, a whopping $15,000 (approx.) saving on the energy bill is possible by opting for an appropriate water treatment program.
