Our AC3000 and AC4000 pneumatic tube systems are commonly set up with multiple zones, each one capable of working independently
But we can provide an interchange for these multi-zone systems, so that your entire network of stations is connected. If only two or three working zones are necessary, then we can construct a diverter transfer to interchange. On multiple zoned tube systems, a diverter interchange can also be used efficiently and can also be spread out in a plant room with limited space available. For maximum efficiency and a far greater traffic flow, a linear coupler is the optimum solution. Read more about what we can offer below, or get in touch with us today to find the perfect solution.
The transfer tubes allow the two separate systems to interchange and a transferred carrier is stored in the interconnection allowing the sending zone to resume work as soon as a carrier has crossed zones. When free, the receiving zone will pick up the carrier to slot it in and forgward to the receiver. This allows a 2-zone system as shown above to have four carriers in transit at any one time.
For systems with more than four zones we construct an independent transfer interchange zone to interconnect all other working zones, this can be expanded to as many zones as required. Additional enhancements can be added to a diverter interchange such as empty carrier return stacking or long distance multiple carrier transportation in series.
The Linear Coupler
For pneumatic tube systems, which expect high traffic flow, the linear coupler is a workhorse transfer system with a much higher turnaround capacity than a diverter interchange.
Where the linear coupler has the edge is storage. Our multiple zone system are supplied, as standard, with RFID carriers, this allows scanning using antennae on all stations. Each send transaction is electronically tagged to the specific carrier using dedicated software, the linear coupler is also equipped with scanning antennae on every incoming transfer tube.
When a working zone transfers a carrier into the storage tube above the linear coupler the zone can immediately accept a new send transaction. The linear coupler, in the meantime, transfers the stacked carriers using bridging logic for the receiving zone to pick up. With multiple tasks to choose from at any given time, the linear then moves to the next available slot. With the arriving carriers stored above the separation unit of the linear in stacks of up to eight, the linear rolls down the next carrier on each incoming zone and logically slots it in. A sixteen-zone system can then have up to 160 carriers in transit at any given time, expand this by adding other innovations such as a CRU (empty carrier return fasttrack) or multibox (multiple carrier transportation) and this figure can be increased.
Our design team are there to face any test. We recently, and against all odds, built a 16-zone linear coupler interchange into a hospital underground car park. At best the working height was 2.8m and obstacles were everywhere. Aerocom do not give up easily, up to the highest level of company management, we joined forces, rolled up our sleeves, worked out the answer, dug a pit, organised the civil work and successfully completed the installation. We love a challenge and have the experience to provide expert solutions.
