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.

What we did not talk about is Mycronic machine. Great choice for small batches.

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.

It looks like one oven is 10years newer than the other, so if we assume same maintenance routine you should get another 10 years if life on it. On the TH side, you know your board complexity - for me wave have much more value than a Selective. Selec

Hey all, I've made a post in the past about us expanding to a new space, but I wanted to do a new post with specific questions. We currently have a DEK 265, Phillips Opal Xii, and a Heller 1500. Our main reason for expanding is to have a lead-free

You might be able to get a step up transformer although I would not recommend that unless it is a good solution for you. What is the input voltage to your facility? It is probably 600V (or something close). If so then you could get a step down transf

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
