Thank you. - Grant

The condenser is barometric, so it relies on having a fairly long drain pipe, around 40 feet vertical into a collection tank. And there are some bends in the discharge @ 45 degrees. I am looking into the design specs vs. what is installed. - Grant

I appreciate the discussion guys, I will look into it. Thanks, - Grant

Thanks, I will use your advice to proceed. Last question, I promise... From what I mentioned before, we run at 200 psi steam, but the ejectors are designed for 150 psi steam. Since the nozzle is a fixed diameter orfice, does this mean that we are getting higher capacity at the cost of reduced...

To answer all of your questions... The condensers have a spray nozzle design. So, while increasing flow rate, I may need to replace the nozzle with a bigger one? The jets are rated for, quote: "minimum 150 psig steam". I know that we run about 200 psi through them. I can test for whether the...

Sorry, I don't have the absolute pressures at each stage. The system, overall, is producing a vacuum of 720 mm Hg on a typical day. The inlet/outlet temps on the condensers are: primary - 84/102 F secondary - 84/96 F The outlet drain pipe is identical in size to the inlet, hence you can...

I have a 3-stage steam jet air ejector system that produces vacuum for a process. The two inter-condensers are direct contact, not surface. The condensers currently operate on 75-80 F closed loop water. A big problem in the hot summer months is that our cooling tower cannot make water cold...

Thanks again for all the help guys, - Grant

imok2, what I'm concerned about with adding a second cooling tower is whether it will be capable of meeting the load when the wetbulb rises in the summer, when the approach temperature becomes very small. I think that a far larger second cooling tower would be needed.(far larger than 120 tons...

I appreciate the help, I will investigate both to see what makes most sense. - Grant

Yes, the same flowrate is required. When you say small side stream chiller, what is defined as small? Considering my flowrate, my initial impression is that a massive chiller would be needed. (The cooling tower is 500 tons.) What about installing a water-cooled chiller inconjuntion with the...

Hi guys, I currently have process water @ 500gpm that is cooled via a cooling tower from about 110 down to 90 F. Our process requirements have changed, and we now need the process water to be at a lower temperature, approx. cooled from 100 down to 75-80 F. My concern is whether a cooling...
