However, KMMC also offers upgraded control packages which includes a VFD for soft starting and stopping, a stop system that always stops the blender with the discharge valve in the down position, and a lock out system that insures that the blender can not operate unless all safety systems are properly set. The blender can be offered as "pre-wired" as an option. Other options include explosion proof motors and intrinsically safe explosion proof pre-wires, etc. Can be offered with controls mounted and prewired as an option.
  • Safety Guarding - KMMC blenders can be supplied with plexiglass safety guarding packages.
  • Casters - KMMC blenders can be mounted on casters. In this case, we suggest our clients purchase a front and back Lexan Safety Guard Package and Prewired Control Package.
