Slotted Wiper Blades

Wiper blades effectively move the product down and off the heated wall in a matter of seconds.

Low Rotor Speed

High rotor speeds are not necessary. The high heat transfer coefficient, provided by the wipers, requires only a 97 rpm rotor speed on our 103.4 sq. ft. WFE. Lower speeds extend the service life of seals and other components.

No Bottom Steady Bearing

Unlike a typical fixed clearance blade design, the WFE rotor is supported entirely from the top drive and bearing assembly, all mounted to the main shell flange.

Low Horsepower Requirements

The low rotor speed significantly reduces horsepower requirements. The 103.4 sq. ft. WFE uses only a 7.5 hp motor. This will prove to be a significant savings when compared to the same size fixed clearance blade evaporator.

Expandable WFE Sizes

Additional thermal sections, for some models, can be installed above the original thermal section at your plant site to provide increased capacity.

Easy Rotor Removal

Any size WFE rotor can be removed and reinstalled in 30 minutes or less because there is no bottom bearing. Disconnect the motor leads, feed line and clamps, then lift the rotor out of the shell as one complete assembly.

Internal Condenser

WFEs with internal condensers minimize pressure drop between the heat transfer shell and the condenser. The high vacuum (shortpath) condenser surface areas are approximately three times the jacketed heat area ensuring condensation and sub-cooling.

Efficient Entrainment Separators

Specially designed full-length entrainment separators for standard and high vacuum operation effectively remove entrained droplets from the vapor stream and improve the purity of the distillate product.

High Vacuum Operation

Our high vacuum design WFE can operate to vacuums as low as one micron (0.001 torr).

Bottoms Outlet

For viscous materials with high melting bottoms, the bottoms trough can be heated and extruder blades can be utilized to mechanically aid the discharge of bottoms materials.
