Be careful Wilco. There is more to it than 220 vs 240. The US has a 110/220 (or 120/240) volt alternating current (AC) split phase system at a frequency of 60 Hz. Based on some quick searching, it appears that Bonaire has two systems, 127 volt single phase and 220 volt single phase, both AC and both at 50 Hz.
Using equipment designed for 60 Hz at 50 Hz has a few implications depending on the specific equipment. Some motors will run 17% slower. Some equipment will draw 17% more current causing it to run hotter than designed which leads to early failure.
The split phase (aka 3 wire single phase) system in the US provides 220 (or 240) volts between the two "hot" wires and 110 (120) volts between each of those and the third "neutral" wire. That allows a 220 volt appliance to also use 110 volts. For example, an electric stove might use 220v for the heating elements but also use 110v for the control system, oven light, etc. A 240V electric brew system might be wired internally to do something similar. Your 220v single phase system can not support that.
And then there are maximum current draws to consider. Higher current requires larger wires.
I'm not saying you can't use any particular electric brew system, I'm only suggesting that you need to look into it much more than 220 vs 240 volts.
I should also mention "230" - some countries use a split phase 230/460 volt system similar to the US 110/220 v approach. There is also 208V three phase in the US and 230V three phase in some other countries - 3 phase is not compatible with single phase.
