Systems and methods for controlling evaporative fluid loss

A system for reducing evaporative cooling water losses using an electric and magnetic field inducing device is disclosed. The device influences a liquid's properties including evaporation rate, diffusion, vapor, heat transfer rate, and/or fluid properties. The device comprises a malleable core with notches and electrically conductive windings wrapped around the flexible core around the notches. An insulative coating isolates the windings from the core. The device is pliable and is wrapped and/or attached around a conduit (e.g., a makeup line or pipe or a recirculating line or pipe of an evaporative cooling tower) with flowing fluid and current is passed through the windings to treat the fluid.
