Evaporation plant

We offer a modular concept to satisfy the demand for evaporation systems for membrane cell alkalis. The concept ensures optimised cost-effectiveness, allowing us to design the most profitable system for a given task based on parameters specified by the customers duty.

Right from the construction of the first plant in 1987 up to the supply of more than 245 evaporation plants since then, Bertrams Chemical Plants Ltd, in collaboration with the caustic producers, has continuously developed new proposals for increased production at lower costs and with lower environmental impact.
