What's the most unusual equipment you work on, or have worked on?
I have four centrifugals that condense acid @ -30F, and hi-low stage screw that liquifies Cl2 @ -40 to -50F at one of my accounts. I would be interested to hear your responses.

This may not seem to out of the ordinary to the refrigeration guys out there but for a guy who usually works on strictly commercial hvac and chillers it was definitely my most unique account. It was a Sabroe 16 cylinder recip compressor with unisab controls which was essentially a blast freezer for pasta sauce. It sat outside the building in a shipping container with a tower on top and ran r-22. At the first breakdown finding parts was a bit of a challenge until we found a supplier in Halifax.

A vacuum cooler for quick cooling of produce.

A big tank and a 50 KW vacuum pump with freezer coils in the tank that the pump draws through. The vacuum pump causes part of the water in the product to flash off, cooling the product, and the freezer coils catch the water before it gets to the vacuum pump. A 25 ton 06 compressor and condensing unit.
It held 4 36X24 pallets.

Made in Blackpool, England, and shipped over on a big skid.

50 cycle stuff, by Jove. None of us Yanks had ever seen such a thing so they sent a bloke over to supervise the installation and start-up.
