Area Classification of Cooling Tower Circulator Pits as per API 500
Area Classification of Cooling Tower Circulator Pits as per API 500
(OP)
My question relates to API 500, section 9.2.4, regarding cooling towers. I have several cooling towers served by a common circulator pit located a safe distance from the basins and outside of their Div 2 envelopes. The pit contains steam-driven pumps with hard-piped suctions, so it is dry (not flooded), but below-grade. The steam drivers will be replaced with electric motors. Does item 9.2.4.1 allow for such a pit to be classified non-hazardous?
