How many detector heads are mounted in the CHT pump rooms?

Explanation:
In CHT pump rooms, you want to monitor the entire space so a leak is detected quickly no matter where it occurs. Four detector heads provide coverage around the equipment and along the room, offering both detection reach and redundancy. Hydrogen sulfide is heavier than air and tends to pool in the lower part of a room, so having detectors near the floor ensures a leak is caught early, while the additional heads extend monitoring to other zones where gas may migrate. This setup minimizes blind spots and speeds up safe response, which is why four heads are used.
