TRAY SEALER OPTIONS
Vacuum & Gas
This option allows the production of modified atmosphere packs. It includes:
Vacuum Pump: Busch 300 m3.
Vacuum hoses and valves Gemu.
Gas reservoir.
Gas hoses and valves.
Vacuum and Gas tool. The vacuum chamber is machined out of a single piece of
aluminum to reduce the risk of leakage. Also all seals are lip seals type and greased
with vacuum type grease. The minimum pressure reachable is below 4 mbar. These
results are important to decrease oxygen residuals and to increase productivity.
PLC software.
Anti-explosion pump
It is mandatory whenever using high oxygen flows or gas mixing and the machine is sold with a
vacuum pump.
High oxygen protection
All the vacuum valves and gas valves are provided with proximity sensor for positive detection of
status (open and closed). A PLC which is separate from the main one checks that the vacuum and
gas system is working properly for each cycle, avoiding a flow of missing gas to the vacuum pump.
In case of malfunctioning the machine detects it and goes in a state of alarm.
Note: this system is not certified and it will be totally under the responsibility of the end user
to be provided with suitable pumps for the type of product to be packed.
Pressure transducer
The vacuum and gas cycle is controlled through timers but the pressure transducer will detect the
level of the millibar at the end of the vacuum cycle and the gas cycle. If the readings are not
between the boundaries pre-set in the recipe, the machine will go into a state of alarm. Also with the
specific menu the machine will close the tool, pull the vacuum to the maximum level and then hold
it. Through the readings again it is possible to see any leakages in the tool.
