What must indirect vaporizers be equipped with to prevent liquid from passing through?

Indirect vaporizers are specifically designed to change liquid propane into gas while preventing liquid from being carried over into the gas system. To properly manage this process, they must be equipped with an automatic means—such as a safety valve or other mechanism—that effectively prevents any liquid propane from passing through into the delivery system. This is crucial because the presence of liquid propane in a gas line can lead to hazardous conditions, including improper combustion or damage to appliances designed to utilize vaporized propane.

The automatic means enables continuous monitoring and management of the vaporization process, ensuring that only vapor is delivered to the end-use system. This enhances safety and efficiency by safeguarding against the risks associated with liquid propane, which can arise if the vaporizer fails to operate correctly. Thus, the presence of an automatic means is essential for the safe operation of indirect vaporizers.
