Softening is a widely used technology for reducing hardness forming ions (Ca& Mg) which precipitate and scale at very low temperatures and pressures. Softening is a reversible ion exchange process wherein the hardness forming ions are exchanged with sodium ions present in the resin group.

Thermax offers a wide range of softening plants with versatility in flow, flexibility in resin quantities and ease in operation. Thermax is one of the largest manufacturers of the strong acid cation resin used in this process.
