Water is one of the most economical heat transfer mediums and is widely used across the industry for cooling applications. Cooling water is often surface water which comes with a high concentration of particulates and needs treatment before it can be used for cooling. Siga Filtration can offer inline basket filters or self cleaning filters for heavily contaminated once through systems. Our downstream filtration solutions can reduce particulate size down to 1 micron if required. Particulates in water can deposit on heat transfer surfaces, block heat exchangers and lead to equipment failure.
