Possible Rolls Royce Coolant tank

**BobL** · 7th February 2014, 05:18 PM

Last year I rescued some old gear from a skip at work and one of the items I grabbed but did not go and pick up until yesterday was this Heat Exchanger that I was thinking of converting into a cooling lube tank
The exchanger is from an old Soviet Era X-ray machine
This is what it looked like when I picked it up

I pulled it apart to see what the inside was like inside.

It's built like a brick outhouse being a rugged all stainless construction gizmo.
The big coils contain the external heating/cooling liquid - in the original case it was chilled water.

This is the really nice stainless pump. I love the way the bolts are all wired together.

The units marked F1 and F2 are adjustable flow switches, one being for the pump and the other for the heating/cooling loop.
Each switch has a diaphragm that is connected to a relay that switches a specific phase of the motor power supply.
No flow in either loop means one or other of the phases drops out which will stops the pump motor.
I don't know how common this or even whether its a kosher way of control.

Motor is 1/2 HP 3 phase easily ∆ and Y configurable

I was going to remove the cooling coils and bypassing the coiling coil flow switch and run it as a coolant tank but seeing as my water feature based pump is working so well I'm kind of loathe to break this one down and may just have to add it to the pile of stuff under the house!

Bob, does it have a small odd looking component in it that is really a remote microphone for the KGB to monitor what was going on at your last emlpoyment fascility? Now they might be monitoring you.....keep an eye out for black vehicles that might "tale you" when you are off to the tree loppers yard

you never know

The guts look very impressive. What else would yit for?

We have loads of Ruskys at the Uni e.g. the whole theoretical physics (i.e. Sheldon types from Big Bang) research group. Maybe they are the intermediate

operators.

I have no idea, but you can bet that if I gut it to use as a coolant loop I will no doubt find one.

Nice! the wiring on the bolts looks like its from an aircraft!
Also like it when motor manufacturers bring out all 6 wires and allow the changing from Y to Delta. It's not that hard to do but it's a nice touch. Makes life easier!

Nice find.

if you had a tig welder, it might make a good cooler to use with a water cooled torch?

I have a tig welder but have never set up to use it - I alway take my TIG jobs around to BIL as he is set up to use it and he also has a much better welder than I do.

I had a look at the sorts of pressure the pumps use and it looks like they use about ~4 bar or 60 PSI, I'd need to check out if the pumo can do this.

Generally with a water cooled torch, you just need to be able to flow about a litre a minute (IIRC). The pressure is not really that relevant, just a matter of whether the pump can push that flow rate through 12 foot (or 24, if you go for the long hoses) of fairly small hose.

My understanding is the hoses are not a problem bit its the fine holes in the torch that restrict the flow and that need that sort of pressure?

Temperature controlled coolant for when you're chasing that last 0.5 micron.

You could use it for a still?????
