GRP and FRP Cooling Tower Shells Compared

GRP/FRP shells are a strong alternative in industrial cooling towers thanks to corrosion resistance, low maintenance and long service life.

The terms GRP (CTP) and FRP refer to glass-fibre-reinforced polyester composite structures. In cooling tower shells this material group is widely used because of its corrosion resistance and low maintenance requirement.

Why a composite shell?

On metal surfaces, corrosion, repainting and the effect of the chemical environment can create significant operating costs. GRP/FRP shells are light, modular and resistant to chemical attack, which simplifies site assembly and long-term operation.

What to consider in selection

Resin type, UV resistance, joint details, service access and the design of the load-bearing structure determine shell performance. In its tower designs, Ensotek combines its composite manufacturing experience with thermal design and maintenance access.
