Mastercool 63010 50 lb Refrigerant Recovery Cylinder

I've read the other reviews and just keep scratching my head. If the tank has non-condensibles from the factory you must boil them off with a good vacuum pump. And leak check prior to first use. That is standard acceptable practice in the refrigeration field. Just like the system you are working on. You must always vac and leak check any new work prior to filling with refrigerant. If someone got a leaky one from the factory just swap it out for another. I've bought the most expensive tanks available from the supply house and had the same problems noted in these reviews. It happens. I once installed a brand new oil storage tank on a dual-fuel system and discovered a leak in it while being filled. It happens. It's rare. But it happens. At least on a refrigerant recovery tank you can check for leaks prior to using it, unlike the oil storage tank I mentioned. A good vacuum pump should be able to vac to at least 500 microns of non-condensibles which is acceptable for all refrigeration work I'm aware of. If you are using a compound gauge look at the reading below zero when vacuuming. It should go down to at least 28 inches of mercury. (Vacuum can be measured in inches of mercury). If it goes there and stays after you turn your manifold set off for a reasonable period of time you know the tank is leak free. Vacuum isn't affected by changes in temperature like gas or liquid. So it is easy to leak check this way. I learned this the first semester in refrigeration school fellows. If you aren't qualified then steer clear of trying this type work. Get help if necessary. Contaminated refrigerant cannot be re-used. If you plan on re-using the recovered refrigerant in the equipment owned by the same person (which is the only legal way) you must ensure that the refrigerant is okay and you must recover it in a 'clean' fashion. Care must be taken to use a drier/filter and a vacuumed and leak free recovery system including the recovery machine and the tank and hoses. Got it today. vac'd it out with a high vacuum pump and tested for 1/2 hour for leakage based on other reviews. I did note there was a lot of liquid inside but was able to boil it off with the vacuum pump. Found no leak or further liquid boil. Vac held at 28 inches of mercury on my gauge. My practice is to always vac a new thoroughly in case I want to reuse the refrigerant. I then connected the recovery unit and vac'd that and the hoses with the tank valve open. Again no leaks or loss of vacuum. I was then able to start the recovery unit and remove the r-22 in the subject heat pump. No leaks after transferring to the tank. Perfect. Can't complain. The supply house wanted much more for the same thing. Remember, if you want to reuse the refrigerant you must thoroughly vacuum the entire set up including tank, recovery machine and hoses before you begin then leak check. There are no shortcuts in refrigeration work. And you must use a good quality high vacuum pump.

value for money, 17.2LB

These tanks are used for contaminated refrigerant recovery and work great!

Lo compre Usado como nuevo, y está en perfectas condiciones

Like the size and quality. Seems pretty simple. Valves seem decent but plastic knobs scare me.

I used this tank for recovering R22 Freon, after performing a proper vacuum, I was able to use my recovery machine and put all the remaining Freon in this tank. Thank you!

Using this tank to do simple AC tasks is a shop necessity and this works well

Everyone seems to go for the huge or bigger brand named products when Mastercool is also up to par with quality as well, and in my opinion just as good at a much lower price! I do not see how anyone else's recovery tanks could be any better built than these! Very solid tank, good valves and it meets the requirements which says alot about their quality! When you stop and think about all the freon sold in disposable tanks that are made according to federal and state requirement guidelines to contain the pressure of the gas that they hold and are completely safe! How can a recovery that's made from what seems to be much heavier metal, both in weight and strength be inferior to a gas that comes sold in a much thinner and lighter tank? In refrigeration equipment, quality is always a must and I have to say that this tank meets if not exceeds the kind of quality you would expect for years of recovery and at a lower price than most! You cannot go wrong! 5 stars and no less!

as above, meets required regulations, light enough for handling in confined spaces and working at heights on scaffolding where one person is envolved.

Buena compra un tanque funcional para su propósito comprare 2 más

Good quality tank. Very happy

Nice quality tank, valves are easy to turn and seal well with comfortable knobs. Paint job is good quality.

Really happy with this purchase! The product works just like described and the delivery was super fast. I’ll definitely buy again
