Cooley Group, Pawtucket, R.I., a global designer, developer and manufacturer of sustainable engineered membranes, has announced the launch of Coolguard® PW, a premier product designed for reservoir liner and floating cover applications requiring NSF 61-certification. The membrane was developed by applying the proven chemistry of Cooley’s Coolguard® product line, used for oil boom, pond liner, portable berm and secondary containment solutions.
 “Coolguard’s consistently high performance is attributable to the chemistry,” says Naresh Mehta, Cooley Group’s director of research and new product development. “Coolguard utilizes Dupont™ Elvaloy® (KEE), a terpolymer component of a proprietary alloy material. This alloy makes Coolguard intrinsically resistant to hydrocarbons and other chemicals in challenging environmental applications where standard flexible PVC would not stand up.”
Coolguard PW is NSF 61-certified (Drinking Water System Components) and has an industry-leading warranty of up to 30 years. It is available in widths up to 10 feet, as well as in tan color for optimal reflectivity and low transmissivity. It’s designed and certified for drinking water systems but can also be used in any critical water application requiring high-performance membrane material, including water containment for brine ponds, gray water, waste water, fisheries and fire ponds.
