Controls

DIRECT ON LINE (DOL): fixed speed control for simple start and stop of the mixing system.

TYPE 1 CONTROL: a variable frequency drive allows analogue control of acceleration, deceleration and mixer speed via a potentiometer located on the front of the panel. A safety lock prevents rotation of the propeller unless the mixer is in a lowered position.

TYPE 2 CONTROL: a variable frequency drive allows programmable digital control of acceleration, deceleration and mixer. The type 2 control system allows the mixer to change between 2 pre-set values, allowing a sawtooth profile of the speeds. Features include simple on/off operation and programmable timed cycles. An auto mode sequence enables controlled mixing sequences, and a safety lock prevents rotation of the propeller unless the mixer is in a lowered position.

All of our control panels are contained in an enclosed cabinet that can be freestanding or attached to the mixer frame or wall. Designed for durability, they feature a pressed mild steel frame, incorporating rubber-protected splash-resistant application buttons, heavy duty ABS variation dials and long life LED indicator lights.
