Not knowing your brand of Heller, I might suggest disconnecting the first cooling section to verify it's your heater fans. I just had a retro kit done to my Electrovert for a similar thing.

In no particular order: Will the failed joints wet when touched with an iron + flux? Is there flux surrounding the joint (post reflow). If no, you may be baking it out premateurely. Is this assembly wave soldered? Where is defect discovered in yo

I haven't used either of them but... The Essemtec distributors & their engineers over here do quite like the RO400 & 300 (typically not much to do on a service but clean them) and the places I am aware of that use them are happy enough with them too.

Proc My field service back ground included Electrovert so I know reflow electrical quite well. I've worked on Heller, Conceptronic and Vitronics over the last few years and really there isn't a huge difference if you can read a schematic. I checked

Hi. 1) recommend to phone up Heller for assistance on this case 2) using the wakeup profile, can you confirm if the problem remains or not when you skip the warm up of zone # 2? 3) each zone is based on 2 heaters (this is what we have on our 1809e

Looking at the full convection reflow oven market, I see two segments, high mass heater ovens (i.e. Electrovert Omniflow,...), and low mass heater ovens (i.e. Heller,...) Did some of you guys did some testing on both types and what were your findings

More zones = higher thruput. Is it better to have (8) 12 inch zones vs. (7) 15 inch zones? One thought might be more parts = more cost = more potential for failure. I have a bunch of BTU's with over 12,000 heating hours of combined opertion. I

The same with Russ, I would look at Vitronics and BTU. based on my experience they give best results especially on the profile. Maintenace is also superb! BTU has modular blower, heater T/C assy. Vitronics is "XPM - NO PM System" Now, BTU offers lif

The nameplate specs for a 2004 Heller 1088EXL show 240V 60A, and specify Largest Heater Load of 25A. As each of the 8 heater elements is 6000W or 9.5R, how does this really work? Obviously all 8 elements on would pull 200A, so does the machine only
