If machine serial tag referring to 3Ph, 208-240V then you cannot apply 3Ph, 380V. In order to use 3Ph, 380V supply you have, machine needs to be retrofitted to work with this voltage. If you apply 380V without voltage conversion, you will damage som

hello everyone, I got a Heller reflow oven that operates at 3x240V and a delta-delta transformer since my grid is 3x380V. the problem I have right now is that there is no neutral line at delta-delta transformer, also there is no neutral line at oven

Thank you Bilal, i am aware that you can't run 3x240 machine at 3x380V, that is why i have delta-delta transformer. It was phase sequence after all, and machine is now running. Thank you all for your help.

1. Why isn't an electrician doing this? 2. Did you measure phase-to-phase voltage between each phase at the machine? 3. Phase rotation only affects the 3-phase motors. If it's out of sequence, the motors will spin backwards but everything else sho

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

Does anyone have used Heller 1700SX (2001) or Heller 1700EXL (1999) for lead free? I found some references in this forum for Heller 1500 but anything for last ovens, just wondering if they can be used though they may run slow.

We had this happen in a Heller 1808 oven when we placed Tant-A caps in glue (bottom side / no paste). We had our oven retrofitted to control the zone blower speeds. No more problem.

hi , we have Heller 1808 and I would say that is doing good job as oven. However for less than 3 years we had to replace 6-7 blowers. There are very nice machines in the market, but it really depends on you and how much money you are ready to spend.

Have you tried to contact Heller?
