Your Challenges

Optimizing energy use

Evaporation and crystallization systems demand careful energy management. Each application requires the right configuration to achieve economical energy use while delivering the required evaporation duty. NSI evaporator solutions are engineered with efficiency as a core design driver. 

Securing consistent process performance

Stable operation across varying conditions is essential. Whether the system operates as single‑effect or multi‑effect, and under atmospheric or vacuum conditions, NSI evaporators are designed to deliver repeatable and reliable process performance. 

Ensuring equipment reliability

Long-term reliability depends on robust engineering, correct material selection, and high‑quality manufacturing. Customers must trust that evaporator bodies, heat exchangers, and all critical components will perform as intended. NSI solutions are designed and fabricated with this reliability in mind. 

How does it work ?

NSI helps you reduce wastewater volumes, recover valuable resources, and improve system reliability with evaporation and crystallization solutions tailored to your process conditions.

The Process

Each NSI evaporation system is fully engineered to match your operating needs. We evaluate process optimization, thermodynamic behavior, materials of construction, and equipment sizing based on feed characteristics. In our certified fabrication shop, we manufacture the evaporator body, heat exchangers, and main process equipment. 
The level of pre‑assembly is defined case by case to support efficient installation. Systems can be supplied as stand‑alone units or as part of a complete treatment system—always customized as an NSI solution for your application. 

Applications

NSI evaporators are ideal for: 

  • Zero Liquid Discharge (ZLD) 
  • Wastewater treatment 
  • Valuable product recovery 
  • Water reuse
