220 or 110 heat treat oven?

A 220v will heat up faster than a 110v of the same size.

ONLY IF IT IS A HIGHER WATTAGE FURNACE. If they are both the same size and the same wattage then they will heat exactly the same. the 22o voilt will draw only half the amps but will not heat faster or better.
 
I only have one 220 outlet in my shop and it shares times with the kmg, disc grinder, hydraulic press and hopefully a power hammer soon. I have a 110v kiln and it takes a long time to heat up. However it is much better than not being able to use my other tools during heat treat, annealing and tempering. For me it is worth the trade off but if you have mulitiple 220 recepticles, go 220.
 
Hey Reeves you do know Paragon is Mesquite Tx you can just drive up and buy it and save the shipping Charges.

We have both 120 and 220V units. The 220 heat much faster, but the 120 work fine and have the versatility to run on a normal 120V plug. While it's true that a 120 and a 220 of the same wattage and size would heat at the same rate, I have never seen them the same. For example, the Evenheat 120V units are 1440 watts and the 220V are 3120 watts for the 14" and 18" and 3600 for the 22.5".

There is no difference in quality of HT -only the speed of the operation

Rob!
 
Rob, when you say faster, how much time are we talking about?
For example, I'd like a 22.5". How long for it to get to temp for both voltages?
And I am so lost when it comes to electricity. Will both cost the same in electricity? :confused:

Sound like you need to wire up a few more 220v outlets!

Here are some early test results for the 120V . The unit has since increased in power.

Here are the temperature test results for the 120V, 12A 4 x 6.25 x 18 knife oven.
8:30 70°
8:45 974° (No kidding!)
9:00 1300°
9:15 1492°
9:30 1629°
9:45 1775°
10:00 1860°
10:15 1920°
10:30 1978°
10:35 2000°

The 220V reaches 1950F in about 45 min.
Rob!
 
The good thing about paragon 220v ovens is that you can get darn big one without having to have a 50 amp circuit. My 24 incher runs on 220/20 like our parents old window unit air conditioners used to. I think that even some of their really big ones still run on 220/30, which is kind of the standard 220 outlet in the US. Having been around the boating world for many years, I know that getting 220/50 installed can lead to a bit of sticker shock at times.
 
Thanks Rob.
Almost 2 hours seems like an awfully long time to get to temp. :(
Guess I'll stick with the 220V. Now only have to wait for you to get them in stock again. I just hope the price hike wasn't too big. :(
 
Don't mean to hijack the thread, but I have a question on this.

Interesting, so an hour for the ramp between 1650° and 1950° for treating S30V. Does that negate the need for 20 minutes at 1650° since it's going to spend that much time at temp anyway?

There's no need for a soak at 1650 for thin section items like knife blades - even with the 220V. Just ramp it up. The piece equalizes fine.
 
Is it just me or is this starting to sound like and extenz commercial... :)

Bill, I assume your 14" is 220?
