MIX model standard range mixers use orifice combinations dimensioned in conjunction together to provide a precise mixture with a ratio of 1:6 flow range between minimum and maximum nominal flow rates. Foam concentrate metering orifice plates houses an embedded check valve to allow back flow into the tank from the mixer. No moving part reduces maintenance needs. MIX model mixers are equipped with water outlet, foam inlet ports, and are completed with isolating valves and drainage valves. MIX model mixers ensure high accuracy at its nominal flow range with lowered pressure losses. Orifice plates are engineered to create a maximum pressure drop up to 1 bar at maximum flow rates, as indicated in datasheets.
MIX models are usually made to provide a fixed mixing ratio between 0.5%- 6%.
On request, a mixing ratio selector instead of metering orifice enables the user to variate the mixture according to the used foam concentrate.
