Cooling Tower Fill is one of the most essential heat exchange components in a cooling tower. Its main function is to increase the contact area between water and air, prolong their contact time, and thus improve the heat exchange efficiency of the cooling tower. High quality fillers can significantly improve cooling capacity, reduce energy consumption, and extend equipment lifespan
Cooling tower fill promotes heat and mass exchange between water and air by providing a large surface area. When hot water is sprayed down from the top of the fill, air usually enters from the bottom or side, flowing in reverse or cross flow. Water forms a thin film or disperses into small droplets on the surface of the filler, thereby increasing the contact area with air. Heat is transferred from water to the air, and some of the water evaporates, taking away latent heat and further lowering the water temperature. This process relies on the geometric design of the filler, including its shape, porosity, and material properties, to ensure efficient heat transfer and low air resistance.
Cooling tower fill is highly sought after in the UK because the country has a large concentration of commercial buildings and rapidly growing data-centre facilities that rely on efficient evaporative cooling. Ageing cooling-tower installations require frequent refurbishment, and strict UK regulations on energy efficiency, water treatment, and Legionella control drive operators to upgrade to high-performance fill that improves heat-transfer efficiency, reduces energy consumption, and enhances hygiene. Combined with the UK’s hard-water conditions and a mature supply chain of OEMs and service providers, these factors make high-quality fill media consistently popular across the UK market.

2) Baltimore Aircoil Company (BAC)
Baltimore Aircoil Company (BAC) is a major global supplier of cooling towers and replacement components; BAC designs and manufactures a broad portfolio of fill media (including cross-flow and counter-flow film fills, VersaCross® and other replacement fill kits) and offers OEM replacement fill packs specifically engineered to restore original thermal performance. BAC manufactures most of its fill in-house and publishes replacement fill kits to match its tower ranges — a strong point for customers who need guaranteed-fit replacement media and documented thermal performance. BAC supports customers throughout Europe and maintains local contacts and distribution for parts and retrofit work in the UK/EMEA market.
3) GEA — (Polacel / GEA Cooling Towers)
GEA (including the Polacel / Polacel by GEA cooling-tower lines) is a large international engineering group that supplies cross-flow and counter-flow cooling towers, packed/column coolers and associated mass-transfer internals. GEA’s cooling-tower business supplies engineered packed media and tower modules for industrial process, power and petrochemical customers; they provide full-scope design, manufacture and aftermarket support in the UK via local GEA offices and distributors. For projects that need engineered packed towers or bespoke packed column coolers (e.g., gas quenchers, packed column coolers), GEA is a go-to supplier with strong process-engineering capability.
4) HEWITECH (Hewitech UK / HEWiTECH Group)
HEWITECH (a specialist plastics-components manufacturer with German roots and a UK presence) focuses on engineered plastic components for cooling towers and wastewater systems — their product range explicitly lists plastic fill media / structured media, drift eliminators and air inlet components for both cross-flow and counter-flow towers. Hewitech specialises in PP/PVC extrusion and injection-moulded components for wet-cooling applications and supplies fills and accessories for industrial and packaged towers; they operate in the UK market through Hewitech UK (distribution and project support). If you want UK-manufactured or Europe-engineered fill media with flexible sizing and materials (PP/PVC), Hewitech is a strong specialist option.
