Dryer likes and dislikes

[TCT]

Saw that, there are also 2 AirJets for sale out of MI.... I think the 72" belt may be to wide for our set up unfortunately
Sure would be nice and a great deal!

Cosmo has an Interchange on DS. Dual burner 72" belt 20' heat. It is 36' long. Overkill for most but that 20K will buy one monster dryer

this should be able to be split into two smaller dryers if it has two heating units.
That would be two Air Jets for $10K each, that's a steal!

Whoa, wait a sec, on the dual belt models are you saying you can turn on one burner and run one belt where desired and save the energy costs???

I don't really understand how gas dryers work, sorry if that's a stupid question.

[ebscreen]

Not that I know of. I think he's talking about splitting the two burners (if there are) from front to back
and having two 10' heated sections as opposed to one 20'.

As far as I know split belts only have different belt speeds. There are many days where I wish we had one.

i believe the dual belt models have a speed controller for each belt.  run plastisol on one belt, run discharge on the other with a slower belt speed.

dual burner models  - not really sure - maybe if one has a super long dryer, the two burners would be able to keep the heat consistent throughout the length of the tunnel.

2 burners would probably just help keep the temps hotter.  eventually you won't be able to heat the volume of air in the chambers efficiently.  2 burners would really help keep that heat up.

Talking about 2 dif things here. Dual burner allows you to run two or more autos uber fast remember its a 20' heat sec, 72" belt. Dual belt is what Zelk says......run at different speeds due to substrate and/or inks. A platisol with an LC additive needs to run through faster for instance.
And it wouldn't make much sense (though probably doable) to cut this puppy in half. Theres a lot more to it.

OK, got it.  Just wishful thinking, a dryer that had a low/high production setting to save cost would be perfect for my shop.   We are typically doing a modest amount of output with the punctuated times of very high output.

Zoo, here is a link to a dual belt one:

Yeah I'm familiar, just was intrigued by the idea of having 2 burners to flip on/off as capacity was required. 

I've found that with enough hot, forced air, you can throw both plastisol and DC/WB on one belt and the both cure correctly but it would def be nice to be able to put a little zip on the plasti side with that dual belt setup.  Not to mention poly's.

[ebscreen]

We run discharge and plastisol side by side all the time. The plastisol just gets a really good cure!

Where a split belt comes in handy is when we're printing discharge on one press and fleece or
some sort of poly on the other. We ave to stop and wait till one is done.

Side note: Modular dryers are initially engineered to expand capacity due to volume rather than disassembled into separate machines. To do so would require 2 new belts (although the existing one could be modified), separate temp/speed/diagnostic panel, additional end bearing, not to mention infeed outfeed supports among other issues. Usually not costworthy.

We recently purchased a new AirJet 76 inch wide belt 12 feet of heat with a IR Bump/8 feet in and out. The air jet has built in hoods that retain 90% of the heat at the ends of the heat sections and it is a very cool running dryer. I have never seen a newer sprint but I would love to know what areas the M&R is better built and why. We paid roughly $24,000 and some change what would a sprint cost with the same specs. We had an alarm code the 3rd day running and they sent there tech out the next day to replace the burner control, all I expected was for them to send me parts to replace myself but i wasn't going to complain.

An equivalent Sprint would cost a lot more than that.   24k sounds almost spooky low for a dryer that size.

we were getting quotes for MD-8 with 60" belt and 8' of heat without the IR bump and only 4' in/out for the same amount!
AirJet with similar specs was at least $10K more.
