Will this Machine Work in Australia?

Once you upgrade to this size you might have problems not only with your power supply but with your neighbors.

2.1kW? My electric tooth brush uses more

The single phase supply in your Australian House / Business is 240 Volt 50 hz nominal. The actual voltage has been falling in the recent few years, if you check with a good meter you will likely find about 234 volts this is allegedly to come into line with IEC (Eurpoean) rulings where the standard voltage is planned to be 230 VAC as a compromise between the 220 V 3 phase system, 240 / 415volt British system and the 115 / 230 Volt centre tapped American system.

The "Biphase" statement accounts for parts of Europe thet still use the 220 volt 3 phase system (Australia is 415 volts). To get the 220 volts required for the load in these areas of the World requires connecting 2 of these phases in the same manner that we would connect 2 phases to a 415 Volt welder.

Why most haven't heard of the "Biphase" title before is because when only 2 phases are connected to a load the resultant current is actually single phase.

If there is an IEC approval on the device there should not be a problem with the extra 10 to 15 volts.

Yeah, but your toothbrush is 4 phase

You could cut down a tree with a 2100 watt (2.1KW) toothbrush.

Isn't mono phase actually single phase. Biphase? thats not three phase.

Yes I think monophase is single, but I'm not completely sure.

Monophase is single phase.

You should be just fine. Make sure your 220V supply power, and disconnect are rated for the proper amperage. I have seen switches to choose between 50/60hz on the power supply.

Monophase = Single phase...

I've never even heard of Biphase... would that be one that's confused about it's ummm... orientation polarity?

byphase that's probally for control.

Only reason it wouldn't work is because it's upside down .

Plug it in (normal domestic supply - prob'ly need to change the plug), switch it on, and enjoy.

It should draw about 12 amps. If your system is 220Y/380, wire between one line and neutral. If you have a 110/220 single-phase system (which I am guessing "biphase" means), wire between the two "hot" (ungrounded) lines. Voltage tolerances will probably work also with 120Y/208 (using two line leads) or 120/240 single-phase systems. There will most likely be some requirements about earthing/grounding; these will depend on local regulations.

Here in Australia 230 or 240V 50 Hz is standard.

2.1 kW should need just under 10 amps, so any power point should be o.k. but if the circuit is also feeding a heavy load on one of the other outlets the 16 amp breaker might trip. If you have a 15 A outlet (one socket only) you will be assured that such faults will not occur. A 10 A plug should be used, as it will work with any outlet.

Since most of the load will probably be the 'fridge compressor and motors, I would have thought 50 or 60 Hz would have been a choice at time of order. The manufacturer should assure you of the 50 Hz rating. If the sealed unit will tolerate both frequencies it will rotate 20% faster on 60 Hz. The production would be slower on 50 Hz unless a very large sealed unit has been chosen. If moved to shows etc in some countries 50/60 Hz might be supplied so the makers could have catered for both. If fine cooling control is needed inverter drive may have been used then 50/60Hz is inherent.

In USA etc 110V supply is usual. This is generally supplied as 220V with a centre tap, 110V each side of the (earthed) centre tap. 220V outlets with both pins 110V above earth are Biphase and quite common with that system.

I agree with most of the previous comments that Monophase will be single phase.

I would think the most likely interpretation of Biphase would be 2 phase. This would be simply two single phase 240V connections.

Here in Oz it was certainly not incommon in the past to see things like a electric range (or stove) with 2 phases connected. This was done to "load share" the appliance. i.e. half the stove, say two hotplates & the oven would be connected to one single phase, while the other half, say the other two hotplates & the grill were connected to another phase.

I would suggest that your machine is wired so that you can either connect it to a single phase outlet, or you could connect 2 separate actives, from 2 different phases, to share the 2.1Kw load across the two phases.

Some houses have a single phase connection to the mains, some have 3 phase (in a domestic situation this was mostly only to accommodate Instant Hot Water systems which required 3-phase power), but, some homes have just 2 phases connected from the mains (i.e. 3 wires - 2 actives plus a neutral).

There are no 2-phase plugs & sockets here in Oz, so this would only apply on equipment which is permanently wired into the power connection (like an oven, or an electric hot water service etc).

Generally you just use 2 of the phase pins in a 3 phase 4 pin plug for connecting 2 phase (ie 415v single phase) appliance (mostly welders).

Use of 2 phases for this machine is not necessary in OZ. Have a look at my previous post it explains how it works here and Internationally.
