Forced Circulation Evaporator
A Forced Circulation Evaporator (FCE) concentrates highly viscous, high fouling, and crystalizing solutions using a tubular calandria and circulator/axial pump for efficient operation under vacuum or pressurized conditions.
Continuous circulation ensures uniform concentration and prevents the buildup of solids on the heating surface area, with MOC (materials of construction) - such as SS304, SS316, or Titanium - selected for fluid compatibility.


Working Principles
Heat Exchange
In an FCE, vapor and liquid remain in indirect contact - the fluid flows through the tubes while steam heats them from outside.
Circulation
Our innovative circulator, directly coupled to the shaft, delivers higher thrust for enhanced circulation through tubes, ensuring a high heat transfer coefficient (HTC).
Evaporation Terminology
Steam applied in calandria transfers heat to the liquid rising inside the tubes, resulting in efficient vapor formation.
Entrainment Separation
In-built UN-MIST technology, featuring an embossed plate-type design, enables efficient separation of vapor from the liquid.
Why Is It Needed?
Enhances heat transfer efficiency through high-velocity circulation.
Minimizes scaling and fouling, ensuring cleaner operation.
Handles high-viscosity and pressurized fluids, ideal for tough applications.
Reduces maintenance and downtime, improving long-term reliability.
