A true Tradesman. Sharing what he knows, so other Tradesmen can benefit. Top notch in my opinion. I have been doing commercial and industrial service for 20 years, and I learn from and appreciate this channel. Gonna share it around, keep up the good work.

Push pull does take a couple more hoses and a little more time to set up but The amount of refrigerant your able to move is astonishing. Especially if your chiller holds 2600 lbs. I’ve never tried that first method you speak of, Gonna give that a shot next time.

@marvinmanoso5604 Год назад

THANK YOU VERY BIG SIR!

@pranavjagadesh8843 2 года назад

Thank you sir, can you make it brief to recover vapour,and the hose connection using a Trane recovery unit.

@Samlol23_drrich Год назад

Great. Thank you❤

@mikecumming412 2 года назад

Great videos! Thank you for putting the time into them. Do you have any plans on doing any videos on glycol loops and ice banks.

Not in the near future

I like to use push pull method.

@kamrulzaman4426 Год назад

Thanks sir this is excellent. how to refill sir from tank to chiller please.

@jonathanbivens2156 2 года назад

My company’s low pressure recovery has different valves you can open and close to change direction for recovery. I push pull then swap valves to pull vapor. I can do 750 lb r 123 in about 5 hrs total

@heeyah Год назад

Which machine is that?

@usernorcalroad 9 месяцев назад

I evacuated an old Trane chiller with pistons and unloaders using just using the recovery machine to the bottle and only seemed to pull half the charge. I pulled from the suction line, and the discharge service valve. Pressurized with nitrogen which held, pulled a vacuum to 360 microns and added the factory charged. Now my low side pressure is going really high quickly. Not sure what I did wrong.

@Joyaguru 2 года назад

what is changing process can you make a video

@karaors8970 2 года назад

nice

@Thermoelectric7 2 года назад

The method with the bottle before the recovery unit is neat, haven't seen that one before. Push pull doesn't look like it would be much quicker than that, short of keeping the pressure in the chiller maybe a little higher. Keen to see the comparison!

@rsesrochester8391 2 года назад

Push pull works like a charm, just recovered 1300 lb of r-123 from a YT, took me 4 hours. I dont see the advantage of hauling multiple tanks, a waste of time and energy in my opinion.

@stephwaylonwells3218 2 года назад

👍

@mmontoya1218 2 года назад

When recovering a low pressure machine and you switch to vapor, do you not need to relieve pressure from the vapor side of the tank with possibly a blow off valve?

@HVACTIME 2 года назад

No, if you run it through a subcooler it will keep temp/pressure down.

@joshua-the-seer8494 2 года назад

Video on how to Charge Chillers yet? What about Leak Search on Chillers?

@BentusiProgenitors 9 месяцев назад

I prefer push-pull. It adds heat and pressure to help push the liquid out.

@mikehendon8124 Год назад

In some instances you can’t drain or flow water. What we do is pull refrigerant to 35 degrees, stop recovery and let machine stand for 30 minutes, if pressure rises it still has liquid. Once it doesn’t rise it’s all vapor.

@JackDavidson-ov2tf Год назад

Just out of curiosity why can't you drain or flow water from the chiller when your recovering? I was always taught to flow water through a vessel or else the tubes will burst because there is no exchange of heat on the tubes

@manachanelbai7837 Год назад

hi, next video you can stop the chiller, then explain very noise

@rsesrochester8391 2 года назад

The Appion G5 is Not rated for low pressure and cant be use legally to recover r-123, if you talk to Appion they will tell you "use it at your own risk".

@alexgarcia1471 2 года назад

Do you use the G5 recovery machine? Or a bigger machine to recover low pressure systems?

@HVACTIME 2 года назад

We use a low pressure recovery machine. It is quite slow with a G5. I was mostly using that as a example.

I pull deep vac on cylinders and put in tamdem, and first suck out as much liquid as possible

Good day . How can i contact you. im working on cruise line . if possible can u please help me in some technical things about chiller

@wd8557 2 года назад

Since I work at Ford, I put my 1000 pound recovery tank in a deep vacuum. Just to see how much liquid It would take without my recovery unit. On a system with 725 pounds it took 370 pounds. Lmaooooo

@buildingstatux7720 2 года назад

Can you please upload a real video of the procedure in the field

@HVACTIME 2 года назад

When I have time sure

@yup735 2 года назад

push pull too time consuming changing all hoses around, still has its place

@realbiker1858 Год назад

I certainly wouldn’t use a residential recovery machine on a centrifugal chiller. You must be non Union. Check out Reftec, they make recovery machines that recover 10 -16 plus lbs per minute.
