The open-loop system operates a vacuum pump with an external working fluid, which is discharged directly, making it an open system. The closed-loop system consists of a vacuum pump, a gas-liquid separator, and a heat exchanger used in combination, with the working fluid circulating within the system.

Depending on the conditions of the gas, it’s generally possible to use a closed system instead of an open one; if that’s not feasible, then an open system has to be used
