The PCS is a system able to keep the nominal pressure inside a large inflatable structures within pre-set values (min. 90 mbar, max. 450 mbar), independently from ambient temperature.The unit constantly monitors the pressure variation inside the inflatable structure and regulates the operation to ensure pressure top-up and pressure relief through electronic pressure sensor.In case of temporary lack of power, PCS keeps all pre-set values and will re-start as soon as the power is back.
