Automatic Filters Inc. introduced its new line of ABW (automatic backwash) filters. The TEKLEEN® filters are useful for the HVAC industry, especially in cooling tower applications. The filters eliminate contamination caused by airborne dust, sand, pollen, algae, and pipe scales, thus reducing maintenance and operations costs. These contaminates circulate through heat exchangers, chillers, and compressors, making the cooling system pump harder, thus lowering the efficiency of the system. TEKLEEN® self-cleaning water filters provide a solution where dirty water is a problem. The filters operate on line pressure alone. The self-cleaning process is triggered by a pressure differential and is accomplished in seconds without interrupting the main flow. The TEKLEEN® filters are all offered in stainless steel construction at carbon steel prices.
