Budget for new hoses
Budget for a new reciever/ drier

Before you do anything, get the fridgey or a/c bloke to pressure test first with dry nitrogen and leave for a few days or a week and re-check, the hoses may be ok, at least for a while.

Follow up on the aircon repairs. I got it done over Christmas. About 10 swage connectors to replace the hose clamps, a joiner where one of the hoses had chafed. Replacement of the drier and hoses from the compressor to the condenser regas and test. All up $1700.00. Bloody gas was $350.00, mutter mutter carbon tax mutter.....
But at least the cab is cool now :D

Exactly,sure the carbon tax increased the cost of refrigerants substantially,there is more carbon tax on some types than others.

But also on the 1/7/2012,all refrigerant bottle rentals increased substantially,and the wholesale buying base price of all refrigerants(before adding the carbon tax),went up at least 100%.

Then you have the phase out of R22(which has very little or no carbon tax on it),which is now around 9 to 10 times the price we were paying for it 12 months ago,by 2014 it will be very difficult to get.This is one of the most common refrigerants.It seems to be increasing in price around 30% every few months,with no direct "drop in" cheaper replacement available.

Then you have the $ value of the refrigerant sitting around in stock,and the risk using the stuff in the event you lose a lot for whatever reason.

Bottom line is working with these types of refrigerants has now becoming risky business,financially.


Good to see the tractor is cool:)

The approach I apply is...

Why are you airconning? thats 6hp coming of the crank that can be going to the wheels or being returned to the tank, and now it costs how much to fix?


Oh you want to feel nice and cold, in that case you get to pay for it, I don't understand the problem.

No Dave, you'll get to pay for it seeing as some large supermarket systems hold up around 600kg of R404a.

At the corporate rate of around $195/kg, Coles and Woolies will be passing the cost onto Mr and Mrs housewife.

Anyway, a tractor cab is a bloody fishbowl and without a/c it's unbearable, even in winter.
Been there, done that and used to take the open tractor out as it was better to be covered in dust and corruption than die from heat exhaustion.

It was actually fuelled (once started) by the huge quantities of dairy products inside. I imagine tons of melted cheese burning and flowing out the door is quite a fire-fighting problem. A mate up that way said even a year later driving past it smelt like a burnt cheese toasty.:eek:

The lack of signage was a major concern. Imagine the problems if it were an ammonia plant that size and the fire-fighters didn't know!

I am surprised at the lack of stenching agent. I thought ethyl mercaptan was in all of them.

What the main wholesalers didnt tell you was that they purchased refrigerant on behalf of the supermarkets and bought up big before 1/7/12, one alone bought 120 tons of refrigerant, R404a included for about $17 per kilo and after 1/7/12 were selling it for $125 per kg siting carbon levy as an excuse. Some of these big wholesalers are still selling their R22 quota's from 2-3 years ago at the new "carbon levy" prices and making a killing. Coles have a contract with Coles City Refrigeration and Woolworths have just purchased Ausral Refrigeration which will can all the little guys out of the market. One wholesaler owns a refrigerant manufacturer/import company and dictates what that company can sell to all the little guys. They all increased their bottle rentals as stated earlier as well. There is a drop in replacement available for R22, Its called SP22 and works very well and about $10.00 a kilo cheaper at the moment (until someone decides that R22 needs to go up again)

And the ACCC did absolutely stuff all about it:mad:

last weel on abc regional was a report of government money being handed out to allow uneconomical organisations to convert to amonia to allow these to become economical..$ millions.

ministry spokesman[minister] said that projects had been rejected as they actually was not in buisness or may not even be built--unlike other grants in the past that had been abandoned after they got grants.

one company spokeman answered the question they had been counting on this gant--but it was tiny compared to other items they had to find cash for and the freezers already worked.......
