Cleaning System for Heat Exchangers

Kamat Pumpen India Pvt Ltd offers high pressure Cleaning Systems for heat exchangers used in sugar mills. All sugar factories around the world face the same challenge in cleaning their big heat exchangers. The most used heat exchanger in sugar industry consists of 500-2000 tubes with a diameter of approx 1 inch and 5-7 mtr length. During production these tubes get clogged rapidly due to deposits from the fluid running through them. If not cleaned within at the right time, the tubes will be completely blocked. But even before they are completely blocked, the thermal efficiency decreases dramatically resulting in an excessive increase of energy needed to keep the process going. Obviously the production output will decrease dramatically due to narrow, or even worse, completely blocked tubes. A very common way to clean these tubes is by using chemicals to soften the scale and then use rotating brushes or drilling bits to remove the material deposited in the tube. This procedure is very time consuming: approx. 2 -3 days per heat exchanger. That is one of the reasons why a lot of sugar mills only take time to clean the heat exchangers during the annual maintenance breakdown. Kamat high pressure system using only water, is a more popular and efficient way to solve this problem. In addition production costs will decrease as less energy is needed to heat tubes with clean surfaces. With this system supplying water @ 30-50 ltr/min and creating a pressure of 900-1000 bar, about 3.000 tubes can be cleaned within a day, if the scale is not too thick already. Even completely blocked tubes can be cleaned with water pressure only. To prevent the scale from getting to thick, cleaning should be done every three to five weeks, depending on the individual production process. This high pressure cleaning system can also be used in many other areas of a sugar mill.
