Whats a good way to preheat media?
Posted by Chris Ranner on November 21, 2016 at 1:51 pmWith the temperature in the workshop dropping I’ve been thinking about how to pre-warm the media and how others do it.
Had 2 head strikes last week using the same vinyl as usual with the same heater settings (hexis hx201) as I’ve been using for 6+ months. I’m guessing that it’s a kind of thermal shock at the preheater thats making the media ripple/wave similar to when I had the heat settings too high before I found the butterzone settings earlier this year.
So, is it worth putting a fan heater blowing down on the media as it enters the printer or blowing upwards onto the underside of the roll?

Only way I’ve found that works is to pre-heat your working space (and the rolls) by putting the heating on at least 3 hours before you intend using it.
You could try those cheapo halogen IR heaters at the back to warm the media (I use them for rapid drying on the front)…not sure how it’ll respond.

We’ve just had gas central heating installed through the full workshop now but before this we had all our media in a small room with an electric oil heater in it that kept the place about 18-19’c. I don’t think it cost much to run

We have one these heating our complete production floor.
Cost us around 8K to buy and install keeps a space of 9000 sqft at a temperature of 19 during the winter months
Cost around £500 – £600 to fill with 1400l of oil.
It hasn’t kicked in since April and only just started having to heat the space again as we are falling below an internal temp of 17
I was reluctant at first to buy this but so glad I did.
Many Thanks

I’m in a similar situation here, gets damned cold overnight – I have to turn the electric heating down to just keep off a chill or it rips through abotu £10 overnight – our landlord saw fit to put in rather inconvenient £2 coin meters after one tenant ripped him off a couple of years back..
While it won’t help me this winter, our Home landlord is changing to Biomass on the estate and we will be connected somehow to that, I’m considering salvaging our current oil fired boiler and re-using it here, simlpy running some rads off of it, it’s pretty cost effective at home and would warm the place up quickly with no worries about moisture which is often caused by gas space heaters.

We use the air to air heating systems. Works well. Has a night mode to keep the chill off or whatever you set it at and full timer modes. It’s set to a constant 18 deg summer or winter. Nice and cheap to run.

Thanks Robert,
What kind of operating costs do you associate with this type of heater and in what size office/workshop?Sorry for the questions, just trying to find a more efficient and cost effective way of heating my insulated office/workshop area which is around 100 cubic mtrs. not very big but can easily eat £6-10 a day when the small fan heaters are running overnight..

Not sure on the heating alone but my last elec bill was £66 for 30 days. It runs 9-5 all year at cool or heat. That’s witg the Roland and Konica as well. Area is about 100sqm + the fitting bay.
Best to got one a bit bigger than you need. Very economical as there a heat exchange unit
-
That looks really good Robert, I think I may be tempted to go that route. Should be more cost effective in the long run than 3kw fan and halogen heaters knocking around the place 🙂

I’m going to try this out this week while I investigate the other heater thing above.
Thanks 🙂
