An industrial chiller is a refrigeration system used to reduce the temperature of equipment, industrial spaces, and procedure fluids by eradicating heat from the system and removing it somewhere else. Chillers often signify a plant’s single main electric load. But factor in fouled tubes, leaky refrigerant, or countless other factors, and operating costs can rapidly intensify by 8% to 10%. Operating chillers at their peak delivery will save up energy and maintenance prices. Here are some of the interesting tips to maintain industrial chillers.

Keep tubes clean for efficient heat transfer

 Heat transfer efficiency has the greatest solo effect on chiller performance, so spotless heat transfer is important to preserving high efficiency. Pollutants such as reserves, gauge, sludge, algae, and other filths increase thermal resistance and decrease the general performance of water cooled chillers India has. Approach temperatures are a decent gauge of heat transfer efficiency. Higher approach temperatures are the main indicators that heat transfer efficacy is decreasing. Condenser pipes should be brush cleaned at least yearly, or per the demand maintenance agenda to keep them away from impurities.

Treat condenser water to prevent scale, corrosion

All industrial chiller manufacturers with water coils using open cooling sources, such as atmospheric cooling towers require water treatment of some kind to eradicate scale, corrosion, and organic growth. All lead to entangling in the condensers and obstruct heat transfer and can cut down tube and piping efficacy. Inspect chilled water loops once a year or frequently with remote monitoring for general water quality and a sign of erosion.

Keep a daily log

 The daily log is still the primary step toward maintaining a professionally-run chiller plant. The log allows one to raise a history of working conditions such as temperatures, thrust, fluid levels, and flow rates. Distant monitoring technologies empower one to review machines repeatedly rather than once a month or every other month. 

Prevent inefficiencies caused by non-condensable

Non-condensable such as air and moisture seep into low-pressure chillers because their evaporators work in a vacuum. Non-condensable can lower the real efficacy of the chiller from the valued performance by as much as 4% at 60% weight and 7% at 100% load. Purge units minimalize the impact of non-condensable.

Keep chilled water flow rate between 3 to 12-ft per second

 Altering the chilled water flow rate impacts a chiller’s performance. Too low a flow rate drops the chiller efficacy and ultimately drives to laminar flow. The lowest flow rate is characteristically around 3-ft. per second.

The actual amount of cooling a chiller offers depends on how much refrigerant it transports through the compressor. A low refrigerant charge will make the compressor work harder for less refrigeration effect. It is significant to uphold the proper level of refrigerant for the circumstances desired. Refrigerant seepages, as well as air and moisture announced into the system, will cut down the efficiency and the dependability of the system.
