Rising and falling film evaporators use vertical tube bundles where liquid feed flows by gravity (falling film) or is carried upward by rising vapor (rising film). These evaporators are designed for high-throughput, continuous concentration of low-viscosity liquids with short contact times. IPP stocks rising/falling film evaporators from manufacturers including Wiegand, Buflovak/Blaw Knox, PMS, and APV.

Crystallizer/evaporators combine the functions of evaporation and crystallization into a single system. They concentrate solutions beyond the saturation point to precipitate dissolved solids as crystals. These systems are used for salt recovery, zero liquid discharge (ZLD), and chemical purification. IPP stocks crystallizer/evaporator units from manufacturers including Alfa Laval, Betchel, Gouda, and Pfaudler.

Falling film evaporators rely on gravity to create a thin film inside vertical tubes, making them suited for high-volume, low-viscosity liquids. Wiped film evaporators use mechanical wipers to physically distribute the liquid across the heated surface, making them better suited for viscous, fouling-prone, or heat-sensitive materials where controlled film thickness and short residence time are critical.

Yes. IPP stocks multi-effect evaporator systems, including a 2-effect Buflovak/Blaw Knox rising/falling film evaporator (IPP# 246737). Multi-effect evaporators reuse vapor from one stage to heat the next, reducing overall steam consumption and operational costs. Contact IPP for current multi-effect system availability.
