Hello again ladies and gentleman,
To those who vaguely remember who I am from my last posts maybe 24 months or so ago and those who of course don't (98%) - HI!
Hope you're well and its really nice to see the forum still going strong, servicing the needs of the incapable, wising up the DIY'ers to the hazards of using 1.5mm flex for shower circuits and generally arguing among yourselves for sport. Top stuff.
Since my last post (which I haven't actually bothered to go back and see what was) i have long since given up the electrical game per-se, and have been working as an Operations and Health and safety manager for a large manufacturing firm based in Hampshire. I am still very actively involved in the plant machinery side of this business and am the on site maintenance tech for any breakdowns but in regards to electrical installs etc I'm leaving that behind - for now.
However - what brings me back to the forum i hear you ask, other than to bore you with the summary history of my employment status...
I am the head liaison for any engineering projects that are taken on here (bespoke machine builds, structural, machine fabrication etc) and we are currently mid way through a new build of a line that we will bringing in to commission end of June, but we have hit a small hiccup on the way.
The engineer currently building the line is not electrical bias and is currently trying to figure out how to put together an infra-red heating section (polycarbonate moulds to be pre-heated before filling) that consists of:
24 x 0.5kw infra-red cassettes.
He was asking me my opinion on the best way to do this and at this stage (being well aware of the thought pattern of most of the elders on this forum) NO I AM NOT BUILDING THIS LINE far from it. We are paying for this build to be out sourced and built in Glasgow I am merely a guide to the engineers as to our requirements and some design aspects, i find myself on the forum today looking to better my own knowledge and understand HVAC and process heating control a little better.
My initial thought would have been to separate the 24 IR cards into 3 groups of 8. Break down a 3/phase supply and utilise a phase per group to keep a common source of singular isolation and lower the current demand and connect each group to a dedicated channel of a 3 channel PID temp controller with integrated SSR, Looking to run at around 90-100 degrees C so a type J thermocouple will suffice nicely, although i am unsure of whether the same and singular thermocouple will service all 3 channels individually? Would independent means of temperature measurement be needed for each channel? I dont really want control of each group independently, just a common means of temp control for all 24.
Sorry for the mammoth post, would really appreciate the feedback as always guys - i hope you're well and still fighting the good fight.
Kind regards,
Ben
