Improve your brine processing performance with Dyvar® technology
Dyvar® is Salttech’s advanced technology for evaporation and crystallization, designed to handle complex brines more efficiently than conventional methods.
Dyvar® - Advanced Evaporation & Crystallization Technology
The Dyvar® system employs patented flash evaporation cyclones. Brine is heated in a separate heat exchanger, keeping the heating and evaporation surfaces apart, thereby eliminating precipitation and scaling issues. Combined with high fluid velocities in the recirculation loop, Dyvar® can concentrate even the most complex brines to the highest levels.
With Dynamic Vapor Recovery, Dyvar® internally recycles heat, minimizing energy consumption. The process pushes brines beyond the crystallization point, enabling controlled salt recovery through fractional or complete crystallization. Developed in close collaboration with industry partners, Dyvar® has been proven across multiple industries and applications, setting a new standard for robust and efficient brine treatment.
One-Step Evaporation & Crystallization
A compact, integrated process that combines concentration with (fractional) crystallization in a single step. Engineered with carefully selected materials to handle extreme conditions: corrosive brines, wide pH ranges, high organic content, and salinity up to 220,000 mg/L TDS.
Fully Electric, Plug-and-Play
No continuous steam supply required. Available as containerized or skid-mounted units: quick to install, easy to scale, and adaptable to a wide range of site conditions. Ideal for rapid deployment, even in remote or space-restricted locations.
Selective Salt Recovery
Enables fractional crystallization for the controlled separation of valuable salts and raw materials, supporting circular and sustainable resource use.
Lowest Operating Costs in Its Class
Delivers high recovery rates with minimal operating expenses. Intelligent process design, low chemical consumption, and automated operation reduce both energy use and manual intervention.

Innovative Flash Evaporation Cyclones
Dyvar® utilizes advanced flash evaporation cyclones, where brine is heated in a separate heat exchanger. This separation of heating and evaporation surfaces prevents scaling and precipitation, ensuring long-term operational reliability.
High-Efficiency Brine Concentration
The system’s unique cyclone design, combined with high fluid velocities in the brine recirculation loop, enables the concentration of even the most challenging brines to near-saturation or crystallization levels.
Dynamic Vapor Recovery
Dyvar® incorporates internal heat recycling through Dynamic Vapor Recovery, significantly reducing energy consumption. It can drive brines beyond the crystallization point, allowing for selective or complete salt recovery via fractional crystallization.
