Chilled Water on Rooftops

Weather-resistant polymer piping systems with low structural impact for efficient cooling on rooftops.

Our Portfolio

Reliable Cooling in any Climate

When cooling needs are high and space is limited, rooftops provide an ideal location for chillers and condenser units. Rooftop chilled water systems serve large buildings such as industrial facilities or other high-demand environments, delivering reliable, high-capacity cooling while making the most of available space.

Exposed to extreme conditions, from -25 °C in Northern Europe to +70 °C under direct sunlight, rooftop systems must withstand harsh weather, wind, rain, and UV radiation. Piping needs to resist cracking and weathering, remain lightweight for easier installation, require minimal maintenance, and maintain energy efficiency. Traditional materials often struggle to meet these demands.

GF Industry and Infrastructure Flow Solutions solves these challenges with COOL-FIT and PE-100 plastic piping systems engineered for rooftop applications, easily handling water, glycols, or brine. Resistant to temperature swings, UV, and general weathering while also bird-proof, these systems deliver up to 25 years of reliable performance. Lightweight and easy to handle, they cut installation time compared with welded metal systems and eliminate the need for additional cladding, while ensuring reliable, efficient cooling for buildings across a wide range of industries. 

Reference Cases

Data center

HICSA, Northern Mexico

HICSA selected COOL-FIT pre-insulated piping for a large-scale cooling project in a Northern Mexico data center. These factory-insulated pipes and fittings are an energy-efficient and corrosion-free for sustainable cooling in the data center industry.

Fast installation

Data Center, Ireland

GF IIFS provided 8 km of corrosion- and UV-resistant ecoFIT PE-100 piping and valves per building to deliver reliable rooftop cooling for 70 MW of power capacity. Off-site prefabrication, installer training, and NDT testing ensured fast, safe installation, reducing project timelines from six months to just six weeks.

Bakery

BÜSCH, Germany

The BÜSCH Bakery in Kamp-Lintfort modernized its refrigeration system with GF Industry and Infrastructure Flow Solutions’ COOL-FIT 4.0. This pre-insulated piping system delivered efficient, lightweight cooling, enabled seamless installation during ongoing operations, and featured UV-resistant, weatherproof surfaces.
