    I'm guessing it's just like a scope, so you can close loop it and "chill" it of sorts with a Rad and two large fans..

    It's good enough for a scope and we are talking similar power levels, a chiller would be overkill I'd think.. the heat load can't be as large as a Ion...

    Just a thought..

    Other than that, I'll happily take it off your hands Steve.. I might even pay you what you paid for it..

    When I was 12, Starlight express was my fave musical..

    "Starlight express, answer me yes.. are you real.. yes or no.." "daahh dahh dahh da" etc.

    Checked URL.. Water to air heat exchanger was/is an option.

    Time to get your plumbing head on Sir hobbit.

    PS:

    You can only use certain materials in the cooling system.. ones that don't ionise your water that is.. it so happens I've been looking into this for a while so if you need any info gimmie a shout.

    Gotta take it along, working or not, want to see pictures! Just out of interest, What are it's power requirements?

    Re the power requirements, I emailed the manufacturer and they have been really helpful. They told me "The power input on these system is about 5kW and they usually run from about 30 Amps of 208-220VAC. When the system is in good shape it will do 40+ Watts of green output power all day long".

    But they also said it really has to be de ionised water, without demons. I think Nige is right the heat output should not be too great, but I don't want to have a fill it with a large volume of DI water, due to the cost of filling each time etc. I have all the connectors and a schematic so connections and interlock should not be a problem. In fact I have since found out that when it toured with starlight it had a custom built water to air closed loop chiller, but this was quite large and so was discarded by the previous owner.

    It will definitely be making an appearance at Surfleet, working or otherwise, just seems a shame if we can't run it up because I haven't sorted the chiller issue in time. All seems in really good shape and it came with a fibre launch system, with a remote head which looks like it has CT6800 series galvos in. So it should be fairly easy to get going. I know we all want to get this running at the meet and so I am franticly trying all I know to sort the cooling issues. Any other feedback really helps, everyone has been a great help so far, thanks

    Cheers

    Steve

    Steve, what's the connector on the fiber launcher? I have some fiber here that may be suitable.

    Cheers

    Jem,

    The system has come with 2 x 100 foot lengths of fibres, complete with galvo cables, all in an umbilical sheath. I will try and get soem pictures posted in the next couple of days, but I think the termination is all there. But I am sure there is something I have missed, thanks for the offer of help

    Cheers

    No worries Steve, glad to help if I can

    Wow!, that really was a bargain, nice that the fiber is included. It's going to be a pretty cool system once it's up and running... Which I'm certain it will be at Surfleet

    Steve,

    Like i said last night ii is likely i have all the parts you need. Have you asked the manufacturer the flow rate of deionised water and pressure required through the laser pump chamber or the heat dissipatation required. Until you know that you cannot know what size of cooler you need.

    Regards

    Steve

    Required Water Pressure: 40psi (276 kPa)
    Water Flow: 1US gal/min (3.8 liter/min)

    Yes,

    I saw that on the spec. Those figures sound like the flow of tap cooling water through a manufacturer supplied heat exchanger rather than flow of deionising water through the pump chamber. I May be wrong not actually that clear. Does steve have a heat exchanger attached to the laser equipment? If he does then his cooling system is already there and all he has to do is run 1 us gal of water a min through the exchanger at 40 psi and the problem is solved. Simples. I get the impression maybe wrongly that no cooling equipment is present on the system ie the pump chamber has cooling ports but nothing attached.
    Regards

    Steve
