Our computerised machine is a bit of a hassle to move about unfortunately.

It takes in total of 15mins for the machine to vacuum out all the aircon lubricant, dirt and then recycles the gas out of the gas system and pump new gas and aircon-compressor lubricant in.

If you can drop by, we can zip ur car out in 15mins.

Regards.

Id be more worried about having dirt in your air con lol

lol 15mins geez pop down lunch time sometime next week
Will this make my aircon cold?

The impurities in air-con gas system undermine the cooling efficiency of the system. A lot of ppl wonder why another air-conditioning system is colder then theirs, esp when they have the same vehicle.

Pumping new gas in is half the solution, having a clean system is what makes it cold. We have many times extracted the refrigerant out of the gas system, let the machine clean it and pump the same gas back in. Wala, airconditioning system is cold again.

We are equippied with a very expensive top-of-the-line computerised aircon machine that can clean, recycle and regas the a/c system, unlike the typical 2 gauge pump systems that most workshops have.

Our machine also automatically pumps compressor oil in to lubricate the a/c compressor, where maintenance is often overlooked by many techs.

Cold it will be.

Theortically, a sealed ac system should never have inpurties in the system.
If the oil is contaminated, its coming from somewhere...ie a leak/moisture.

'Theoretically' is an understatement Master D.
High pressure and low pressure a/c valves cannot seal 100%. If that were the case, cars will never ever need regasing.

Ever engineer would know this: Even in a closed energised equilibrium system from macro-mechanics down to atomisation, there is always a loss of energy somewhere.

However, you brought up a good pt. Should there be a leak in your a/c system, the Hychill gas we use is an environmentally friendly gas that is 100% Australian developed. This gas encompasses a green dye that would show outside of your a/c system if there is a leak.


[QUOTE=Master D;616815]Theortically, a sealed ac system should never have inpurties in the system.

To be concise Master D, compressor internals do wear and corrode to an extent, reacting with the a/c gas, resulting in contaminats in the a/c system.

The receiver dryer and condenser also produce enough contaminants due to moisture, which is very common in any a/c system.

So even if the a/c system is closed shut, impurities will still be present in any ac system overtime.

Not to argue, but if a valve leaks, its faulty, it needs replacing.
I know that by law (under the arctik scheme) i cant leave a refrigeration system with a leak. If the refrigerant contaminates a compressor, if causes rust, then you have a leak.
I have opened systems that have been sealed since installation 30+ years and never found a rust.
Driers remove moisture from a refrigerant system.

If your using this ezychill or whatever gas... I havent seen the properties of it but i look after machines that are 100x the size of a ac system running on R134a.. if i opened it up and there was rust id be looking for a leak and lookin to replace whatever the rusted component was.

But hey. Sounds like your machine does a kickass job :-)

Thanks Master D. So I'll assume that you deal with large commerical refrigerated equipment?
