    Inside the compressor chamber, how high is the pressure around the surrounding piston?

    I really appreciate you guys.

    Love the tip of never pressure test over low side limit. I went through a two year HVAC-R tech school a few years ago and did not learn that there or in the field from any "senior" tech.

    What about rotary compressors? Is the fusite on the high pressure side of the pump? Just wondering since the suction gas directly enters the pump?

    Good video. Thank you for sharing and taking the time to make the video. Are you in Ottawa ?

    So when pressure testing no more than the low side rating in the suction. Then how about the high side . Never mentioned about the high side marked in the Data plate

    I had a Emerson compressor on a prep table blown up through the S terminal. The customer said he heard a big sound and "air leaking" sound when the compressor failed. The customer has no any knowledge about refrigeration system. He tried to let it run by putting the lead back into the hole and glued it on. Every time when he plugged in the power, it trigged the breaker!! When you let customer describe what happened, you can hear some funny stories. This customer tried to fix it by himself, but no success!!

    Brian if I had just 1/4 of what you know I'd be okay with that hahaha!. Keep them videos coming.

  19. Avataaar/Circle Created with python_avatars Juan Acosta says:

    Wean u say over pressure meaning the pressure beeing to low or to high

    Great video
