This type of system is without the service liquid recirculation. The service liquid arrives directly from external sources at a suitable temperature for the regular functioning of the pump and it is discharged by the pump together with the process gases. Once separated from the gas, it is disposed of. The below P&I refers to a typical full-optional system without service liquid recirculation. There is also the possibility to engineering its parts following the customer’s requests. The system can be entirely supplied including the control panel or, as alternative, it is possible to require only the necessary components.
