After selecting a few ovens based on the mfr's specifications, I plan to send them a thermal "slug" to run in their ovens (a 1/4" thick, high temp fiberglass slab with imbedded thermocouples). Since we are replacing ovens with fixed speed blowers wit

LOL! Good to know! Yeah, we have 3Ph with a high leg, so technically at 240V, so we should be fine. Since nobody has really mentioned a real preference with the ovens, is it kinda like what I thought at first? That an 8 zone oven is an 8 zone oven.

If your ovens are 480V you may be able to convert them back to 240V by changing out the elements? There are industrial suppliers for oven elements out there. sarason

So do you guys really not like running oven's this large at 240V? Or do you just not like the two ovens specifically that I mentioned?

In my experience Heller makes a great, no frills oven that just runs. The only Vitronics oven I've dealt with was over-engineered and gave me nothing but headaches.

The ovens you're looking at need 100 amps of 480, 200 amps of 240. Do you have that extra power available in your building? You can go with a step-up transformer to convert 240V to 480V. My understanding is that ovens run more efficiently on 480V.

One thing that you do not want to do is run a 240V oven at 220V. One place I worked a few lifetimes ago had an oven that had five top zones and only two on the ends on the bottom. It was something like 440V but supplied with 408V. It took a long long

We have 3 Heller 1800 units. They run great. Our building is 208 3ph. One of ours is running 480v, so we bought a transformer to convert. I am not familiar with the other oven you mentioned.
