Will nitrogen cylider blast if regulator is not connected properly..? How to avoid this..? Pleasee reply
Hello. The nitrogen cylinder won't explode, but incorrect use of the regulator can cause an explosion outside of the cylinder. You can avoid this by making sure that the regulator is properly connected to the cylinder, without any leaks, and make sure that the pressure setting on the regulator does not exceed the safe operating pressure of the vessel that the nitrogen is being fed into. You can consult the manufacturer's specification literature for specific values.
Whats the difference between the left gauge and right gauge?
Hi Michael. The left gauge shows the pressure leaving the regulator, while the right gauge shows the pressure in the cylinder.
@@paradigmcooling8497 why does the right hand gauge always show 0 PSI in the video?
Can you also add single phase motor test
Hi Makhadzi. That's a great idea. We have added it to our list of requests.
How do you check to see how much pressure is inside before using ?
Hi Jalice. The nitrogen regulator has two gauges fitted to it. One gauge reads the pressure in the cylinder and the second gauge shows the output pressure of nitrogen leaving the cylinder. In order to see how much pressure is in the cylinder, you simply have to open the cylinder with the t-style handle on the regulator still closed (as per normal operating procedures), and the high pressure gauge reading will rise to represent the cylinder pressure. The low pressure gauge should show zero at this point with the regulator still being closed. In this video, you will notice that the cylinder pressure is very low, hence the high pressure gauge showing very close to zero.
Can I use the Schrader valve core remover right at the beginning? For new systems, practically BEFORE evacuation? For older systems, in cooling mode, but still switched off (there is a slightly pressure).
Hi Joe. Yes you can.
Thank you for the info. Can you please post the rest of the tasks.
Thank you for your comment. We will be uploading the video on the efficiency test on a compressor in the next week or so.
What did you connect the yellow hose from the valve core remover tool to?
Hi @safetyalways7788. The yellow hose on the video is connected to my digital vacuum guage. Now it is important that the hose used be rated for vacuum, or alternatively just use a Micron Coupler, which is the industry best practice right now.
@@paradigmcooling8497 ok
This is the best video made on the topic. Appreciate you. My only question at this point - the manufacturer specifies pouring oil down the vacuum inlet port during the oil change. Can you demonstrate that part of the process?
Thank you Gary. Yes the charging of oil through the vacuum inlet port is an important part of the oil flushing process when the replaced oil is badly contaminated and we should definitely do a video on the process. Thank you for the suggestion and we will certainly add it to our production list.
Thank you for the video. I have an argon/co2 regulator .Can I use it with nitrogen since fits to tank if I change the left low gauge to 100-600 psi one? Thanks.
That's a very good question. Conventional wisdom suggests that you could theoretically use an argon/co2 regulator for nitrogen applications provided that the fittings match the cylinder being used and that the maximum pressure threshold of the gauges is sufficient to manage the cylinder pressure. You could of course add additional adapters and fit new gauges to make the regulator compatible, but my personal preference is to use the correct regulator for the gas it was originally designed for. It is also worth a mention that the pressure regulation legislature in your country may prohibit such modifications under its safety laws. I would research them thoroughly before making any changes to the equipment. thank you for your question and be safe.
@@paradigmcooling8497 Thank you very much for the reply. Best regards.
Can you do a video pulling a vacuum with this pump on a condenser coil
Yes we have a video in the works that involves a vaccuum decay test on a condenser, using this exact pump, which may be what you are looking for.
Thanks for sharing the video. I will test pressure gauges with a nitrogen cylinder and regulator valve with an increase and decrease dial not a handle like yours. Do I have to turn the dial to the decrease side all the way before I open the shut-off valve of the cylinder? or it doesn't matter. Any safety tips? After I test each pressure gauge, do I have to shut off the cylinder? Thanks again. 👍
Hello there. Yes it is best that you leave the regulator closed all the way before opening the cylinder. This is just to make sure that the pressure coming through the line doesn't exceed the maximum pressure tolerance of the guage that you are testing. You can gradually open the regulator until you get to the desired test pressure. Also, if you are testing multiple guages then it isn't necessary to close the cylinder after each test. You can just close the regulator after each test until all the tests are complete. Upon completion of all the tests, you can then close the cylinder as a final step.
Does the regulator have to be shut before opening the cylinder valve ?
Yes, it's best to do it that way in order to properly regulate the pressure coming out of the cylinder. It allows you to slowly raise the pressure to the desired level without the risk of rupturing the system being filled. I have seen a technician pre-set the regulator for a pressure test on an evaporator and upon opening the cylinder, the evaporator immediately ruptured because a part of system was weakened due to wear and tear. Luckily no one got hurt but the bang quickly cleared the building. Lol
