Re: RO2 ENVIRONMENTAL SPECIFICATIONS



Have you considered the use of vortex tubes to keep your electronics cool?  
Small, no moving parts, and nothing to wear out.  All you need is pressurized 
air (80 PSI and above provides good efficiency though they will work as low as 
30 PSI).

FROM KEENANP@DETROITEDISON.COM 
 
HOW DO YOU ADDRESS ENTRIES INTO HIGH TEMPERATURE AREAS OF THE PLANT THAT 
REQUIRE RADIATION MONITORING WITH THE EBERLINE RO2? THE TECHNICAL MANUAL GIVES 
AN UPPER BOUND OF 140 DEGREES F BASED ON THE ELECTRONICS. 
WE HAVE NUMEROUS AREAS IN THE PLANT WITH TEMPERATURES GREATER THAN 140 
DEGREES AND HAVE EXPERIENCED ELECTRONIC FAILURES OF RO2 AFTER FIFTEEN MINUTES 
IN THIS TYPE OF ENVIRONMENT. WOULD APPRECIATE COMMUNICATION ON HOW YOU HANDLE 
THIS ADMINISTRATIVELY OR OTHERWISE. THANK YOU IN ADVANCE.
