mixes.
- More economical than premixed gases.
- Models for vacuum and flow packing machines.
- Direct reading flow set dial.
- Easy to use with single dial mixing rate set up.
- High flow rates.

Flow rates given in liters/minute ( 1 L/min =
2.118 cubic foot per hour )
To convert cu ft per hour to liters per min divide the cu ft by 2
for a rough estimate.
To convert L/min to cu ft per hr multiply the liters by 2 for a

Introduction to the Map Mix
9000 The PBI MAP Mix 9000 is a proportional gas mixer for air,
argon, carbon dioxide, nitrogen, oxygen, and similar gases. The mixer is
suitable for a range of applications in modified atmosphere packaging, welding,
process control and similar applications. The Mapmix can be set up for use with
all kinds of packaging systems including horizontal and vertical form fill and
seal machines and vacuum systems. The gas mixer settings are stable and
repeatable. The gas mix is set directly by the user using the mixer dial on the
front panel.
Principle of Operation of the MAP Mix 9000
proportional gas mixer 
The MAP Mix 9000 is a
pneumatic device which works by balancing pressures from the
input gas supplies to ensure that the component gases are mixed
at the same pressure regardless of their individual inlet
pressures and flow rate. The unit provides constant mix control for a wide
range of flow and pressure conditions. The gases are combined in a
chamber fed by variable orifices, which are set by the mixing
control on the front panel. The mixers are factory set for the
gases you specify. In a two gas system the mix control is
calibrated directly in proportionality 0 - 100% - gas1/gas2.
This single control sets up the required mix. In a three gas mixer,
where there are two proportional regulators, the proportionality is set with two
controls to set the total mix. For
vacuum packaging systems or other applications which draw an
intermittent flow, a special control valve ensures accurate
feeding of a ballast tank. Built in alarms monitor the pressure
conditions in the mixer to ensure correct mixing conditions. |

What
size mixer do you need ? - some guidelines
For flow packaging
Measure the volume of your biggest package in liters V -
multiply this number by the fastest speed of the packaging
machine in packages per minute S - multiply the result of
this calculation by the purge factor 2.5
Mixer capacity = VxSx2.5 Liters/min.
For Vacuum packaging
Make the same calculation and substitute the volume of the
die for V and 1.5 for the purge factor. (There is less
wasted gas in vacuum machine therefore the purge factor is
lower ) |

the mixer includes two proportional regulators to mix the

In the case of a vacuum machine the mixer feeds the ballast
tank of the vacuum machine and the outlet pressure of the mixer can be adjusted
to match the packing machines requirements In the case
of a flow packing machine the mixer provides a free flow mixed gas to the
machine which is usually at low pressure. The mixer can maintain the flow up to
the maximum outlet pressure. |
