Type III — Low-PressureQuestion 163 of 240
The rupture disk on a low-pressure chiller is a safety device that is typically designed to relieve at what pressure?
a.10 psig
b.12 psig
c.15 psig
d.25 psig
Explanation
The rupture disk on a low-pressure chiller is generally set to relieve at 15 psig, protecting the low-pressure shell from over-pressurization. This is exactly why leak-test pressure must stay at or below 10 psig. The disk must never be bypassed or blocked.
