GRP / GRE  Full-Contact Internal Floating Roof

Application-specific internal floating roof technology for safe, reliable and low-emission operation of covered aboveground storage tanks.

Introduction
NXT-FC-IFR is a GRP / GRE full-contact internal floating roof designed for covered aboveground storage tanks. The roof floats in direct contact with the stored liquid and is engineered to eliminate vapor space, improve emission performance and support reliable tank operation.

​

Each NXT-FC-IFR is designed according to the actual tank geometry, stored product, operating conditions and project requirements. The composite construction is selected for the chemical environment of the application.

​

Installation is performed inside the tank by WLI’s qualified field service team using a site-built GRP construction method.

Engineering / Construction
