Forced Circulation Evaporators
Buflovak Forced Circulation (FC) Evaporators use a high efficiency circulating pump designed for large volumes and sufficient head to provide the force for evaporation. These evaporators deliver a controlled temperature rise and temperature difference and guarantee optimum heat transfer tube velocities. With a high rate of heat transfer, rapid evaporation and high concentration is achieved without requiring high operating temperatures or large heating surfaces.
Product Details
Forced Circulation Evaporators are recommended for heat-sensitive materials and viscous, scaling, salting and crystal producing liquids. Since the liquid is only heated in the steam chest with flashing taking place in the separator and no boiling taking place within the tubes, fouling on hot tube walls is reduced.
FEATURES & BENEFITS
Forced Circulation Evaporator
Forced Circulation Evaporators may be equipped with either vertical or horizontal steam chests. The circulating pump withdraws liquid from the lower part of the vapor-liquid separator and circulates it through the tubes at a high velocity. Boiling is suppressed in the tubes either by liquid head or an orifice plate. The heated liquid is discharged into the separator where the vapor flashes off due to the temperature difference and is removed through the top outlet. The liquid is discharged at a maintained liquid level.

Sample Applications
Testing & Lab Rentals
Test your materials in one of our world-class pilot scale testing facilities. The Buflovak Research & Test Center located in Tonawanda, NY provides access to multiple dryers, flakers, single and double drum units, and cast iron and chrome plated drums. CPEG’s Innovation Center & Testing Lab in Louisville, KY, provides access to a variety of additional process equipment technologies for multistep processing. Lab rentals are available when it is not feasible to perform testing at one of our facilities.
