Electric oven

I am looking to purchase an electric oven from my new bakery deck oven and having an issue with three-phase electricity since I only have single phase 220 in my store any ideas and anything that works to convert three-phase two single phase ?

most of the ovens I'm looking at I difficult to convert meaning you have to change all the elements and it can be very costly

thank you

hi, perhaps a phase converter could work. I've purchased one from these guys in the past for a 3 phase mixer. http://www.wolfautomation.com/ they have a pretty good tech dept. 

also try this link http://www.thefreshloaf.com/node/4603/clarifiying-matters-about-ovens down towards the end.

good luck with your search

If a solid state drive does not have a sufficient power for your oven, rotary phase converters are available in a wide range of sizes.

Thank you

but how how big of a rotary converter do you think I need I'm buying a five decks Sveba dahlen

and also would the converter be very expensive ?

I've noticed that some converters can cost in the thousands 

thank you

According the the Sveba Dahlen web site, their largest deck oven (model DC-4) has 4 decks, with an electrical load of 12.6 KW. This would require a 20 HP rotary phase converter to power this large oven. Always consult a qualified electrician before purchasing or installing electrical equipment.

Have you consulted your power company regarding getting a three phase drop to your place of business? It may be that the pole transformer already has the necessary phasing and needs only to be terminated with the necessary drop wire and breaker box. if a new transformer is required, it may be the cost can be amortized on your energy bill. Running 3Ø will almost certainly reduce your electric bill due to reduced peak current loads.

Thanks Bob and Gary

the Sveba is a DN-53 it is a 5 deck and puts out 39kw 

The Service is underground and there is no 3ph in the main 

Can a new transformer be placed , and would it be cost effective ?

If a rotary converter is the way it looks like i would need a 50hp?

Looks like they run between 2 - 5 k in price 

What to do ???

Thanks for your help

Are you referring to the power company's lines, or your service drop? I would expect three phase power lines unless single phase has already been split off to service a residential neighborhood.

That is a question you need to ask the power company.

For a 39 KW resistive load, you would need at least a 60 HP rotary converter to power such a large oven. If practicable and not too expensive, you should have a 3 phase service installed. Check with your electrical service provider. Otherwise, a phase inverter is required to operate the oven as configured.
