    [QUOTE=Healey Nut;12813321]If down time is critical then they should have a back up plan , either a back up chiller or at least the quick connects availabe for the water hookups for a rental chiller . Mechanical stuff breaks down thats why we have jobs , if the facility is to cheap to realize this and doesnt invest the money to protect its buisness from loss of production due to a failure thats not my problem .


    True redundancy has a place but where do you stop with the making of a "plan B", the world is also changing and unfortunateley accountants are the decision makers not those with any engineering background. Investment in equipment is tied to ROI, LCC, etc. I can't always say the change is an improvement but it is the reality that reliable efficient performance is the key.

    So what products/systems are going to go ahead, the one were additional standby capacity is installed just in case because mechanical stuff does break down or the system sold on reliability and minimum capaital investment supported with a pro-active maintenance regime.

    Coming from the "long screwdriver and good ear" era I can also say these capabilities are also becoming rarer in the trade as is experience (from making the mistake before) so to survive long term in the business the technology to assist in this area must be accepted.

    I guess the best example of the change is when you compare the efficiency and reliability of the 30 yr + equipment still running today to the new high efficiency equipment being installed that will be replaced at or near the end of it's life in 15-20 yrs time. You also did not need computer literacy to be a chiller mechanic but we all have accepted that change. End of the day does it matter because I guess neither of us will be worried about it, hopefully.

    This spot on correct , so many of the guys these days are just parts changers , the computers says change this , oh that didnt work now change this... oops try again whats next, next, next .....

    My experience comes from doing this for the past 30yrs when VA wasnt even thought of .
    I take my cars to car shows and the young guys cant believe that it has carburettors and points/condenser and a real distributor and they dont have a freakin clue what to do without their OBD telll me whats wrong with it plug in .
    Bet you replaced a lot of stuff to fix this is up is another question .....my answer ...No I restored it 90% of the car is original parts that I restored and repaired and brought back to original condition . Any fool can pick up a catalogue and order parts and bolt them together ...restoration takes patience ,skill, and understanding .
    Something that has started to be sadly lacking in the trade these days because of the reliability on high tech gadgets to do the work for you .

    At hte same time I see a lot of older techs and E&C take a look at any kind of control panel and immediately state "I haven't been trained on that" (some of it's a union thing). If I'm in a bad mood I'll remind them that I've never had a single day of training on any controller for any equipment I've ever looked at... and no, I'm not jsut a trial and error button pusher. If I don't know for sure what it does, I don't touch it. I either ask questions to the service tech or figure it out. Geez. It's not that hard. I swear, some older guys see anything that looks like a computer and freak out. Funny, the same guys will take a glance at a cluster of relays or a schmatic or look at a group of hand valve s and start throwing switches, valves or sticking a meter on it, but if it has a HMI...

    The long screwdriver, stethoscope, analog amp meter, multi-amp/variac/whatever, megger, and vibe analysis all have their place. The bottom line is that a comprehensive maintenance and service program utilizes all of the above. I like today's technology, because I think all of these advancements help elevate our trade beyond the perception that we're overpaid lawnmower mechanics.

    Vibration Analysis is a trade all in itself. Jayguy if you got your level III, Congrats - and you can turn wrenches is pretty much Rock Star status in my book.
