Introducing the world's most advanced venturi mixers that are virtually maintenance free, highly accurate, and provide easy and fast adjustment.  Groz mixers use a rotary disc valve which is precision CNC machined from stainless steel.  Other venturi coolant mixers are designed with either a needle valve or set of mixing jets.  These designs can be time consuming to adjust, have too many parts, and/or are prone to blockage.  The Groz Plus Antifreeze/Detergent Mixer's rotary disc valve is highly accurate, and their compact construction and minimal parts make these coolant mixers easy to install and highly reliable. 

Groz has made specific modifications on these mixers for Coolant Consultants, lengthening and switching the suction tube from plastic to a threaded stainless steel pipe.  The pipe screws in securely and will not fall off into your drum!  The adjustable collar allows for different height drums.

CAUTION:  These units cannot operate with any back pressure, so they can only be used to fill a pail or nearby container.  The outlet hose cannot be restricted or used to shut off the mixer.  The outlet hose must NOT be connected to any device that can restrict the flow.  This means NO sprayer devices, in-line systems, or piping overhead lines.
