Scale formation, biological growth, corrowsion and other sediments found insde air-condition condenser tubes have always been a problem for maintennce enginerers.
These elements, if not controlled and/or not eliminatedd altogether , will cause many implications to the air conditioning system in a building. Thus, often cleaning of condenser tubes internal surface is required.
The ATCS will continually keep the tubes clean throughout the year. Through this system, sediments will have no chance to settle and harden over time. When the internal tube surfaces of the condenser are clean, they will result in better heat transfer. With better heat transfer, the chiller system will achieve higher efficiencey, thus saving the building owner thousands of dollars in energy costs.
Through research and development (R&D) over the years, the ATCS has improved its cleaning system to using a Booster Pump. (depicted in the picture). The Booster Pump help to inject all the natural rubber balls into the condenser water supply (CWS) inlet pipe. There is no drainage of treated cooling tower water. This innovated system works at a low and high CWS pressure.
OPERATION SEQUENCE (see installation concept drawing):
When the countdown time is out, a signel will be sent to the Diaphragm Valves (2a) and (2c) to open for a pre-set time amd Electric Valve (5a) to ATCS system #01 opens as well. The Booster Pump will also start to run. CWS is pumped, passing through (2a) , the Booster Pump and the through (2c) ad ito the the Ball Collecter (yellow, 3a), hece pushing all the rubber balls out int the CWS pipe line. The rubber balls are carried into the condenser unit and clean the sediments off the tubes. At a pre-set time, the Diaphragm Valve (2b) and (2d) will open, and the Booster Pump starts to run again. At this stage, it pumps the condenser water to the CWS pipe line, and at the same time returns all the rubber balls to the Ball Collector. A cleaning cycle is thus completed. This sequene will then move to the next unit at a pre-set time.
This sequence will be repeated until all ATCS units are completed and the PLC will go into countdown mode again.
The ATCS Boost Pump Systme works perfectly wih low pressure (as low as 1.0 Barg) and high pressure (up to 20.0 Barg) condenser pressure applications.
