Question 1 of 2066636eee28f7522a1c51ec1f

You are installing a new refrigeration system aboard your vessel. The system comes with a 240 psi rupture disk, a safety valve set at 240 psi and a pressure gauge connection and gauge. In accordance with 46 CFR, what is the preferred setup for installing the equipment on the condenser?

🔍 Key Concepts

• 46 CFR requirements for pressure relief devices on refrigeration condensers • Difference between series vs parallel installation of safety devices • Purpose and behavior of a safety (relief) valve vs a rupture disk and a pressure gauge

💭 Think About

• Which device must have the most direct, least obstructed connection to the condenser so it can protect the system effectively? • If one device lifts or ruptures, how would that affect the ability to read pressure on the gauge and the operation of the other protective device? • In an overpressure event, do you want the system to depend on multiple devices in a chain (series) or allow each device to sense the condenser pressure independently (parallel)?

✅ Before You Answer

• Verify in 46 CFR whether pressure-relief devices and rupture disks may be installed in series on refrigeration systems • Check if the regulations prefer that each protective device be directly connected to the condenser without being isolated by another device or valve • Confirm which arrangement best prevents a single blockage or malfunction from defeating all overpressure protection
