Look at videojet.com for small character ink jet (CIJ). We print on (beer)cans, bottles, steelplates, plastic bags and so on. Here waterbased ink doesnt help.....it dosen't dry fast enough

Yes I know.
Thats a good idea.
Phew, I'm glad I'm not doing that.... And I'm glad that at big part of my work includes label printes and applicators. It's not so dangerous.....
Water heater ?
Were I live we have on big "water heater" burning household waste and sending (selling) us hot water through pipes, for heating and for hot water at home - Very convinient for the whole city :-)

You're talking about "waste-to-energy" plants and "district heating".

yep - kind'a your area of work :-) I was not sure about the correct words....

No, not inkjet inks -- they are all water based. I'm guessing David Nebenzahl is talking about inks used in printing presses (probably modern offset ones).

No, read the response to my post: these are solvent-based inkjet inks. Like the ones used to mark things like wire and cable, drink containers, yogurt containers, etc., etc.
I know about offset inks, having recently owned a printing business. Offset ink is basically the same as it was 50 years ago, except for the newer-ish rubber-based inks.
So where were you guys (speaking to Klaus now) when I needed you? A few years ago the company I was working for was looking for a way to print direcly on plastic (in full color), and I did a *lot* of research into this, but never found a source. Oh, well.

Most Americans get their hot water from 30-40 gallon tank heaters with either gas-fired or electric heaters. Bigger buildings still might have old-fashioned boilers like you're describing.
Of course, you Yurpeens also have those "on-demand" water heaters near the place where the water is used, I'm told.

Mine is not "old fashioned", but rather new and is covering the whole town by burning waste.
It is not very common in Denmark.

Link error, the correct is
Normally district heating pipes are laid in the roads and streets and sets of pipes for each house are branched off. In the house the set of pipes enters a heat exchanger which supplies energy for room heating and domestic water heating. This way the high-pressure district heating water is not used in the internal curcuits of the houses.
Yeesh! Use 91% isopropanol instead (available off-the-shelf at many pharmacies) and avoid all that badness. They clean babies with it, it's harmless.

Then we must have low pressuer dirtrict heating here in Hammel. We only have heat exchanger for domestic water heating.

You may have local heat exchangers covering a larger area connected to the main net of Hammel Fjernvarme. See
Btw, both Hammel Fjernvarme's two lines are designed and constructed by Vølund, now owned by Babcock & Wilcox, see
How is the heating paid for?

Water will kill you if you drink too much at a time, it's happened! grin Remember living is a death sentence!
