Evaporators

Evaporators Overview

Evaporators are essential equipment designed for concentrating liquid solutions by removing solvents, typically water, through controlled evaporation. PM Industries offers robust and energy-efficient evaporators ideal for chemical, pharmaceutical, food processing, and wastewater treatment applications. Our evaporators are engineered for high performance, minimal thermal degradation, and easy maintenance, ensuring product quality and operational reliability.

Working Principle

Evaporators operate by heating the feed liquid to its boiling point under atmospheric or reduced pressure, causing the solvent to vaporize. The vapor is then condensed and collected separately, while the concentrated liquid remains in the evaporator. Various types of evaporators, such as falling film, forced circulation, and multiple-effect, optimize energy consumption and processing capacity.
