Confirm three things before any packaging machine ships: supply voltage and frequency, single or three phase, and the connected load in watts. Machines are built to the destination supply, and a machine wired for the wrong supply cannot simply be plugged in on arrival.
What varies across machine classes
Bench sealing and coding equipment is typically single phase. Chamber vacuum machines, shrink tunnels, baggers and automation stages commonly require three phase, because the pump, heaters or drives draw more than a single-phase supply will carry.
What to confirm before shipment
| Item | Why it matters |
|---|---|
| Voltage and frequency | Built to destination supply; not field-changeable on most units |
| Single or three phase | Determines the supply you must have in place |
| Connected load (W or kW) | Sizes the circuit and the plant supply |
| Heater load vs motor load | Heaters draw a steady load; motors draw a starting surge |
| Compressed air | Pneumatic stages need capacity, not just a connection |
Orders of magnitude from our catalogue
Across the series we supply, published power figures span roughly 300–2000 W in the sealing range and 1.2–1600 W across shrink and seal-cut machines, with heater-driven stages sitting at the top of those ranges. Automation stages and turnkey lines are specified per configuration rather than per machine.
The mistake that delays commissioning
The most common delay is a three-phase machine arriving at a site with single-phase supply at the intended position. The fix is electrical work at the plant, which takes longer than the shipping did. Confirm the supply at the exact machine position, not at the building entry point.
Voltage and power are published on every series page in the full catalogue.

Frequently asked questions
Can a machine be converted to a different voltage after delivery?
Some can with a transformer, many cannot economically. Specify the destination supply at order.
Why do heaters and motors need to be considered separately?
Heaters draw a steady load; motors draw a higher current at start. Both matter when sizing the circuit.
Is compressed air needed on all packaging machines?
No, but pneumatic sealers, case sealers, strappers and most automation stages need it. Size the compressor for the whole line.
