Pressure and temperature Monitoring

SFP HydLok systems all feature a HMI (Human Machine Interface) module for the primary system control and monitoring. This provides the operator with alphanumeric display with menu driven operation and control system fault diagnosis. The display also provides temperature and pressure indications for the system and additionally has a communications port to allow connection to PCs or suitably interfaced data loggers.

Temperature Control.

Here we are not only referring to pre / post conditioning of the product before passing though the system or on its way out (i.e. after cooler). There are processes such as some liposome productions where the product must be maintained at temperature as it passes through the system or the processing will be ineffectual or the machine unable to operate properly. With Liposomes which must be processed at elevated temperatures, 70°C for example, if the temperature drops through machine then the Liposomes are unlikely to be processed correctly and additionally are likely to adhere to elements inside the system, such as NRV components, so causing a malfunction. While some manufactures have overcome this by immersing the system in a water bath this is not ideal and for electrically operated systems dangerous. The SFP system has provision to allow the principal wetted metal components to be maintained at temperature by circulation of temperature controlled (heated) fluid so that these difficult processing conditions can be maintained.
