The mixers are by design "fail safe." They will either operate correctly or, if that is not possible, will stop and give a warning.

The mixer consist of a number of individual solution mixing units, up to 2, 4 or 6 which are mounted in a cabinet. Each solution unit mixes or recycles small batches, typically 4.5 litres.

The mixed or recycled replenisher solutions are pumped into storage tanks which provide a buffer stock. One mixer can supply several processors, If only modest amounts of chemistry are required the solutions can be stored in the mixing tanks and the processors draw from these.

The capacity of the mixers, depending on the process, is about 30 litres per hour/solution but, because mixing takes place in small batches, they are also suitable for much lower throughputs.

The mixers require a supply of tempered water and power and can either be plumbed to a drain or a collection bottle.

The mixing sequence follows the convention of adding the chemical concentrates in turn, either to the overflow to be recycled and or to water. Each step is checked and if not correct the mixer stops and gives an audible and visual warning.

The MM3 use a volumetric method to meter the constituents of a mix. Self priming pumps and water solenoid valves feed the overflows, concentrates and water into a measuring chamber mounted above each mixing tank. This is filled to a precise volume determined by preset level probes and then a solenoid valve in the base opens, releasing the contents into the mixing tank.

The MIX DATA - the mix sequence and mix times - are programmed into a memory chip and the precise quantities of each constituent are set by adjustable level probes. No adjustment of metering pump cams is required. The quantity dispensed depends on the volume of the measuring chamber, which is unlikely to change and is almost completely independent o pump characteristics. The plug-in memory is easily replaced or reprogrammed on screen.

An efficient impeller, driven by a low voltage motor, mixes the overflows, concentrates and water thoroughly in a few seconds.

A 4 line LCD display and audio alarm provide fail safe warnings and in combination with a keypad, a very simple to use calibration and diagnostic facility.

Almost any type of chemical pack can be used - plastic bottles, drums, or cubes. Large packs reduce chemical costs. For dimensions, technical specification and ordering particulars consult specification sheet and price list.
