Our quality assurance program involves a review process where the product is evaluated for fit and function, engineering requirements and product validation. We manufacture products for a variety of industries including Industrial, Chemical, Agricultural, Environmental and more.  

One of KemFlo’s most successful products lines is their plastic random packing line which is marketed under the Kempac brand name.  The Kempac family of products include three styles of plastic random packing including the Tri-Pack, Pall Ring and Saddle type. Each style of packing is available in three sizes and in a variety of resin types.  

The most popular packing is the Tri-Pack style packing.  The Tri-Pack style packing is one of the most efficient plastic random products on the market today.  The Tri-Pack style packing is a hollow spherical packing constructed of a network of rids, struts and drip rods. Its spherical shape allows each part to roll into the packed position without forming void areas which are common to irregular shaped packing. There is no need for allowances for settling and nesting is virtually impossible. The Tri-Pack also offers reliable and predictable loading of your tower which means reliable and predictable performance. In addition to the superior geometric shape, an active surface area is vital to mass transfer.  The unique network of ribs, struts and drip rods have proven to give the Tri-Pack an advantage in providing excellent wetting qualities and maintaining liquid distribution throughout the packed bed. Some suppliers claim more surface area, but surface area alone is not an indication of performance. In fact, excessive surface area can impede proper gas and liquid contact and always results in higher pressure drop which increases horsepower requirements and operating cost. The Tri-Pack offer an optimum surface area to open space ratio which results in superior mass transfer efficiency and reduced operating cost.  

The Tri-Pack can be utilized in a variety of applications including air pollution, scrubbing, air stripping, absorption, distillation, extraction, humidification, dehumidification, biological filtration and more.  The Tri-Pack is available in three sizes, 1”, 2” and 3.5”. KemFlo manufactures this product using only prime, virgin resins and no recycled materials are every used. Almost any injectable resin is available, but the most common resins include Polypropylene, Polypropylene with Glass, Polyethylene, CPVC, PVDF, Halar and more. All of the plastic random packing that KemFlo manufactures in polypropylene resin has been certified by NSF to Standard 61 for water treatment plant applications.
