    TXV Training Sources

    I'm looking for training sources for my counter people to become more knowledgeable in refrigeration TXVs. I've emailed my rep from Sporlan/Parker to see if they have anything, but he has not replied yet. Does anyone know if there is anything out there that I can look into?

    What info are you specifically looking for?
    Knowledge is knowing that a tomato is a fruit. Wisdom is knowing not to put it in a fruit salad.

    The Sporlan website page which pherman linked to has everything anyone would want to know about TEV's...and and everthing else.

    Here are some suggestions:

    Solutions For Fixing TEV Problems gives a good, basic overview of how TEV's work and presents a number of typical service related problems:
    Their Quick Tips are very good, highlighting many common issues:

    Using The P-T Card As A Service Tool is a must read for anyone in this business. Counter guys who know how to use a P-T chart will have a much better basis for understanding many of the the system components they sell.

    I found this educational video on Youtube which does a pretty good job of presenting and explaining the function of refrigeration system metering devices:

    The Youtube poster has quite a number of related videos in his playlist which you also may find useful. The one I linked to above does get chopped up at the end and I haven't checked out any of the others as yet. I'd like to determine the original author of these vids, so if anyone can find that or recognizes who created them, please let me know as I'd like to add them to the Educational Forums.
    Thanks

    Not a statement you would have ever seen prior to the Parker acquisition.

    thankgoodness,

    We use the Parker training staff every year to present their NATE authorized seminar for our customers. The trainer is out of Atlanta. We also have our sales staff attend these meetings. They do an excellent job and I highly recommend them. We also have our regional Danfoss factory rep present his seminar which is also an excellent class and NATE authorized.

    I also have a training class for our sales staff. A/C TXVs are much easier to choose than the valves for medium to low temp so my class is based on how to size a valve using the btuhs at a given SST using charts (not the listed nominal tonnage). Why internal versus external, why use an orifice in the distributor, where MOP valves are used etc. etc. One important step to them teach is what questions to ask so the correct TXV can be chosen.

    I don’t get very deep into how a valve works, just how they can pick the correct valve for the customers application.

    I have found that factory training and local training (if you have someone in your company with the ability) really do pay off.
