One Customer’s “Zeal” to Replace a Z Purge System

November 14th, 2011 Leave a comment Go to comments

I thought this short application success story was worth sharing!

A major chemical company was looking for an economical solution to purging cabinets that are used in Division 2 hazardous areas. Division 2 locations are areas where hazardous gases are only present under abnormal conditions. The customer has been using a Z Purge System, which not only purges the cabinet but maintains a positive pressure in the cabinet. The positive pressure keeps the hazardous gases from entering the cabinet where a spark could cause an explosion. The economical solution tested by the customer was a model 2510 plastic tube flow meter. The model 2510 variable area flow meter flows a known volume of purge gas into the cabinet which maintains a positive pressure. A flow meter is not the answer for every customer but it worked for this one!

Do you have a similar application? Let us know.

    I assume the installation does not come under ander AHJ or insurance goverance as the the flow device is not certified/approved for hazardous service.

    Hello Jim R.,

    Yes, you are correct the device does not carry approvals but based on the rating of the installation area it can still be a valid solution.

    Thanks,
    Jim
