Need help for topping up chiller gas.

[devil_xiaozhu]

Hi can I know where can top up chiller gas? I was quote 120 for topping up the gas. Plus they can't confirm if it will not leak. I'm using Hailea 130a is it worth it to top up?

bioplast would be able to.
or try checking with air conditioning servicing companies.

Why do you need to 'top up'? The gas is not used up during the chilling process, unless there is already a leak.

I was told that may not be leak. The gas inside the tank may turned to powder form if the ventilation is not enough to cool it. Anyway I found someone to replace the gas tank for me Le. Thanks for everyone's help

I don't think the gas in chiller needs to be topped up unless there is a leak.. If I am not wrong, there is a thread about chiller's gas being in a closed loop.. If there is a leak, the water won't be chilled and even after topping up or mending, there is no guarantee that it won't leak again...

If I change the whole gas tank will it be ok? After hearing all ur advices I'm worried. :/

Why the big process of changing the gas chamber? Unless you are using Arctica 1/5hp and above which cost a lot to buy a new one (they have serviceman that can solve these issues anyway), if it's Resun or Hailea, just buy a new one..

If buying a poorly maintained chiller at a low cost but gives you more problems in the long run, then might as well buy a brand new one which at least has warranty coverage right?
I am not saying that sellers of secondhand chiller are not good, I had good buys too.. But buyer have to take the extra note on checking the chiller before buying..

By the way, bro xiaozhu, if you are to ask around how much to change the cooling gas tank, I believe you can buy a new chiller (if you are getting a chiller which is like 1/10) with the cost...

I have read something before

A good condition working chiller will not need any gas top up. If they is needed then the life span of the chiller is gonna gonner

please accept my understanding.. the gas (freon) should not be top up. short explanation of how cool air/water is created;
the gas will be compress from vapour form then through various process, heat exchange and etc to liquid form, the heat will be absorbs through in the process.. the gas will always be recirculates- re-cycle back to the chamber(compressor).
the possoibities of not able to cool maybe due to the usual suspect a leak, or chockage of the gas(freon) at the fitler, expansion valve and etc.. had read that the gas may break down due to long usage(many years under extreme condition)

best bet is to perform a leak test which is not very diffucult for a chiller unlike our air-condition, the coil is lay much longer.

Hope this help.
