I remember working on those on the cranes above the pots at the Gladstone smelter,in another life years ago.

They ran on some refrigerant that we had never used before and I have never seen again.....

Ian, I don't think that is the same Clima. The company I dealt with was in West End and owned and operated by the founding partners. Clima units were almost universally fitted to heavy plant like dozers, loaders, dump trucks. The mining companies insisted on Clima a/c. The units were designed to be robust, repairable, efficient in 50 degree and more ambients in the coal fields and the north and west and to cool an 80 ton dozer that had been sitting in the sun. If the a/c stops working then this is a "machine down" situation in the mines which raises the ire of any pit boss as he is getting his arse kicked for lost production.

Every chance, Brian, sometime in the last forty or fifty years they've been taken over, merged or changed the name and structure of the show whilst retaining the good name of the original.

Happened here a few times as well with some well known A/c businesses over recent years. People believe they are going to receive the same Expertise of the original Co, which in most cases was excellent & was built up over many years of trading but are sadly disappointed when they don't & the job goes tits up.

It is all very well to sell the name but if they don't have the bollocks to follow through then it is doomed from the outset. If there is a bad reputation involved, they inherit that too.

Yes, I have found a few like that. One place I used to buy auto parts from and had brilliant service, lots of stock, guys who knew their stuff, were taken over, I am sure, for their good name. Then the shop was moved to an outer suburb, the name eventually disappeared, and the service went down the sewer. Now there are no counter sales, you have to have an account facility with them and an ABN number.

Close,pilot solenoid valve,very common on big DX systems,which are getting rarer and rarer.CHanges over when de energised,putting liquid pressure under the TX bellows,forcing the valves spring pressure to close it so the system pumps down.

I think thats right,Rick?

Not a good pic,the pipework is shocking.And its an Alco valve,not the good old Sporlan.

Had some fun these last few days,and nights.

Someone,running mains cables, decided to accidentally drill onto a 250mm PVC chilled water line in the ground.

We have taken this much gravel out of the strainers of the two primary Chilled water pumps,so far

Now all the strainers in the AHU's are clogging up with grit and mud

AHHH,all fun and games.
