ProTherm® 50 evaporates up to 99% of solvent in a single pass

ProTherm 50 has approximately ½ square foot evaporation surface. All process wetted parts, are 316L SS and electro-polished. It also comes with an aseptic gas-backed mechanical seal and an explosion proof motor. It is easy to operate, clean, and can be validated.

ProTherm 50 operating principle

Centrifugal force exerted by the rotor blades holds a thin film of feed material against the heated wall. The blades continually renew the thin film as the incoming feed displaces progressively more concentrated material towards the bottoms discharge nozzle.

Vacuum is maintained in the system to minimize operating temperature. The residence time is less than one minute to preserve product quality.

ProTherm 50’s capacity depends on the operating conditions and solvents involved.
