GF Piping Systems’ COOL-FIT PE Plus is the pre-insulated polyethylene piping system ideally suited for glycol, brines and chilled water used in secondary cooling applications. Handling fluids from -58°F to 140°F (-55C to 60°C), this solution is corrosion and scale-free, up to 65% lighter than metals, UV resistant and 100% water and vapor tight. It is joined using electrofusion technology — a fast and simple process that is extremely reliable and minimizes the human factor., the company notes. This maintenance-free and energy efficient solution is available in dimensions from d32 (1") to d450 (18") as a standard range.
