I just bought a tunnel dryer from Ebay and I notice it is 3 phase. I am told that single phase house supply will not work. Whta are my options please...I do google searches for more info but you have to be a quantum pyshicist to decypher the information on this subject.

Is there any way I can make it single phase or do I have to pay a small fortune for single phase to 3 phase convertor?

What are the benefits of 3 phase? is there a cost saving - given it uses a lot mopre power than the standard 240v (In U.K)

I also bought a screen wash which had the backlight wiring cut and there were three coils - the courier commented it had three phase power but at the time I din't know what he meant until I bought this dryer.

To upgrade a house to 3 phase is very expensive: they have to partially re-wire. You'll only generally find 3-phase in commercial buildings. Basically you have 110+110+ground.

I have the opposite problem currently: we're moving into a commercial bay with 3-phase but my equipment is 1-phase. We basically made a break-out display that negates the ground wire leaving us with standard 220V.

Contact the manufacturer for sure, you may not need that extra headroom and you may be able to simply swap the head off the cord. Otherwise, hey, I'll buy that dryer off you cheap!

There are phase converters out there that will convert single phase voltage to three phase, very expensive. I read a post a few weeks ago on screenprinters.net forums where someone had the same problem you are having and they were able to rewire the unit to work with single phase voltage. You might want to do a search there. Like evryone else suggested, contacting the manufacturer is what you need to do.

Hey guys thanks for the advice. I asked my colleague at work today (he used to work for one of the biggest Electricity suppliers over here in UK - Powergen) and he said lots of customers used to ring up asking about three phase power. He said it involves digging up the street pavement and swapping your energy box and also your meter and then rewiring (like a previous poster mentioned) He said the customer has to foot the bill so i assume that would be ÂŁ5000 minimum. Considering I am starting off in the garage of my rented house which is a brand new build on a beautiful estate I don't think there is a chance in hell! However I have seen converters on Ebay for ÂŁ100 - ÂŁ200 . Would this do the trick if the manufacturers say the power cannot be changed?

Also would the manufacturers still offer advice on old products. I have attached a photo of the dryer. I don't know too much about it at the moment until my courier delivers it (delivery has been a fortune in itself) . By the look of it though it looks like its a non commercial small dryer so I would assume that it started out as single phase? What do you think?

Thanks

Sometimes it takes a village....

Anyway, 3P power comes in on 3 legs and is used in commercial equipment. The power company here charges more for that type of setup and may even charge a separate 'demand' charge. Basically, you pay for your highest demand in addition to kwh.

Now, suppose you get this converter and run it. What happens? You use electricity. There may come a day when the power company knocks on your door and wants you to convert to a higher rate because of your consumption. Also, your local city officials may frown upon you drawing an 'unfair' amount of utilities compared to your neighbors. I am not sure how you do things in the UK but in the Peoples Republic of California running a business out of a house is legal as long as you do not create business type of traffic including, but not limited to: delivery trucks, commercial equipment, demand for city services, demand for utilities, etc, etc, etc. Of course when you use an unusual amount of power/water in SoCal the local police may give you a visit to see just what might be in your house.

Good luck.

Ok the dryer has arrived and it looks awesome.... I have been watching on ebay for a cheap converter but they are all ÂŁ100+

Has anyone heard of a tunnel dryer having three separate plug sockets for one machine - there was one on ebay some time ago and i wondered why it needed three sockets, now I wonder if it was once phase three and they used three sockets to convert it to single phase?


Any Ideas?

OK I contacted the manufacturers and he was great, sent me an email with all sketches of which wires to reconnect but sounds like I will have to drill through walls to my mains box and as the house is rented I am still unsure.

This has been in my garage for about 6+ months now so I bought a flash dryer. I will get round to fixing this sometime.

Has anybody else converted a three phase to a single phase?
