Electric Heating Elements

How well do you think these elements would work? You can get them 2500w to 6000w. The 5000w will run a person around $40 shipped.

Re: Electric Heating Elements

The literature says it's for duct heaters which means they need a fair amount of air moved across them or they'll go up in smoke.
IMHO

Re: Electric Heating Elements

think they can handle 450*?

Re: Electric Heating Elements

Couldn't say for sure but usually duct heaters burn up fairly quickly without ample airflow.
You could always contact the manufacturer and see what they have to say.

Re: Electric Heating Elements

doesn't it look like what they used in this oven?

Re: Electric Heating Elements

Yep, sure looks like it but it's hard to tell.. I'd either call the manufacturer and find out or just buy one and give it a whirl. They might be fine..

Re: Electric Heating Elements

Tri-J, I just built a 4'x4'x6' oven and used the coil type elemnts. I have used the oven a couple of times and found they work but you do need air flow over them or they will have a short life. I have since found a new element to use which is the cow rod type, sort of like the one in your household oven. They are 5600 watts which is 19208 btu's. They are commercial elements and cos around $50.00 a piece.

The new elements (3) heat my oven to 400 deg. in about 25 mins. and do not require the fan that I put in. I am not at the sop right now but will get the manufacturer and part # for you later. Hope this info helps. I know I had a heck of a time finding info like this.

How much airflow I planning a 4 X 8 X 4 oven with a squirrel cage circulation fan (not fresh ail), how many CFM will I be needed with the coil style element?
The elements will be mounted in the exhaust side of the ail flow.

Re: Electric Heating Elements

I used a 215 cfm blower from Dayton ind. If you have access to a Grainger cat. they have them in there. I got the high temp blower motor which cost me $118 delivered.

Re: Electric Heating Elements

Is that enough CFM across the coil stlye heaters?
Do you have a link for those "cow rod" heaters

[termite11]

Re: Electric Heating Elements



215 CFM is in my opinion just right. Not to much to blow things araoun but enough to keep the heat moving and the elements from burnung out (found out the hard way). The rod type elements are made by Gemline and I still have to get the numbers for you. I will go down teo the shop tonight for them. These are a few photo's of my latest oven.

Re: Electric Heating Elements

And a few more.

Re: Electric Heating Elements

Last two!!!!

As you can see my elements are inside the wall of the oven. It protects them and gives you more ovent pace. It also puts them in the air stream.
