    Replcae two chiller plates in this sheet printing press.




    Here is one of two chiller plates that go under the dryers.
    They weigh about 125# each.


    The plates go under there, in the pit under the press.

    Put both of them in and the had to take them back out, disassemble them and field repair them because the factory shop guys got in a hurry. Here is one plate disassembled and the factory service tech worrying wiith it.


    It took 10 hours but they were warming it up and loading ink by 9 pm when we left.

    Thumbs up

    I have gone all night on the same type of problem with a printing press chiller that keeps the the ink under some high intensity UV Lights at a constant temperature. The outdoor temperature was -10 and after the man on the job replaced flate plate heat exchanger all the refrigerant went to the outside condenser when he pumped the charge back in, unit kept tripping low pressure. Had to run the thing for 20 min with the condenser fan shut off to get it to run. The only thing I didn't see in the pictures was the guy in charge asking how much longer four times an hour. Great pictures!

    These two plates are under the Ultra Violet and Infra Red drier lights. Runs chill water thru them just to keep the plate cool. 850 under the lights. They run heavy stock with a plastic coating and the heat is warping the plate under the UV lights. We installed the redesigned plates.

    Three sales reps from two companies,
    two presidents from two companies,
    two techs from the press manuf.
    and a crew of press operators,

    all standing around asking "How soon?".

    Nothing like having an audience.
