Default Help with a 3 phase deep fryer

How can I make my 3 phase deep fryer into a 240 v for the house. I have only 240v in the house.

Do you have a schematic for it? It probably has three "Y" connected heating elements. You might be able to drop one of the legs, and use it at a reduced heat with single phase. But you need to see how it's wired, control voltage, temp controls etc.

If it has a drawing on the cover show it to us. The three heating coils may also be hooked up in a delta [triangle] also. Take the cover off and shoot some picks.

Default Fryer conversion

Most likely your single phase current in your residence, is 240volt, and your plate on your fryer shows 208volt. Without changing the elements to 240volt rated units, your element life will be shortened considerably. Most all commercial heating appliances arrive wired for three phase current, and it is the installers responsibility to convert it to single phase. The cover plate should have the info you need on the inside of it.

Default Fryer

Vulcan Hart was bought out several years back by Hobart Corp. You need to contact your nearest Hobart service/parts shop, to determine if the elements are available. Sorry about the delay in posting an answer.

I don't under stand why the need for new elements?

Correct me if I'm wrong, but...

3 phase 208v is within 10% of 220v which should be close enough for a coil.

3 Phase power is simply 3 different single power lines run in a specific phasing or relationship.

There should be 3 different heating coil elements, each assigned to a single leg or line of the 3 phase input. Conversion to single phase should involve separating the inputs to the individual coils and setting the heating elements up to run in parallel (ie common inputs and outputs to each).

The control should be a simple on/off thermostat controlled affair that calls for power when the temp is lower than set point and shuts off when hot enough...

What am I missing??!?
