    Emergency water line purge with compressed air/gas

    Hi BigInch, Thanks for you input. The thing is... the internal coils have paths such that it is not drainable so gravity would not solve the whole problem; currently I have installed drain valves on the return side. well the reason I mentioned 3-way valve is that I thought about having to...

    Emergency water line purge with compressed air/gas

    Hi all, I would like to ask for advice for the following issue... My project is a process cooling water for equipment in our plant and this problem applies to cryogenic equipment... The process water is delivered to the equipment which has internal cooling coils, if there is a power...

    Demin Water System

    Thank You bimr... Alright, I have checked with the suppliers and manufacturers and they did say cooling channles are made from copper... and they said should be ok running DI water through... I am having conflicting information, thought DI eats up copper, so should I size a much bigger...

    LN2 (LIN) delivery system and conversion to N2 gas

    Oh by the way, I will be talking to suppliers etc about LN2 system details however I do want to get inputs from all of you before I talk to those people (my experience is that they dragged me in circles..............)

    LN2 (LIN) delivery system and conversion to N2 gas

    Hi all, I would like to get some advise and help on this problem: Our ultra-high vacuum vessel requires venting/purging (>15 m^3 volume) and I was charged the assignment to deliver dry gas for this process. I did sized a compressed clean dry air system, dew point to be -100F (max I can go)...

    Demin Water System

    Hi bimr, Well, the manufacturer specifically asked for DI water; and the capacity is quite large due to the large number of devices, high power RF equipment, that needs cooling. My current problem is .... more like they have given me a "black box" and I have to design around it, so please...

    Demin Water System

    Oh ok I see... Yea.. the problem is some ARE copper... since there are quite a bit of devices needed to be cooled so... therefore I figured a resin bed is need to keep the conductivity down... however I am struggling to size it and all the other assocessories that come with it (I am novice to...

    Demin Water System

    Tank material is most likely fiberglass, or polyethylene; piping material are most likely 316 SS In my design I am assuming a closed loop system. The reason for using demin water (DI water) is the cooling water will be used for cooling some electronics and RF devices... was told that this is a...

    Demin Water System

    Kenvlach, would you mind elaborate a bit more on: "dissolve the system"? the equipment and devices which cooling is required asks for DI water... Thanks!!

    Demin Water System

    Hi all, I am in process of designing a chilled demin water system and with some specs here: Approx 1300 GPM, transient heat load: 10MJ, requirement is provide chilling capacity to dissipate 10MJ within 10 minutes. The design chilled demin water temperature is 50F. I am thinking having a...
