HTST - Model AV-9900 - Recorder Controller
The new AV-9900 is specifically designed for use in continuous pasteurization applications. It combines failsafe protection for the pasteurization process with the broadest range of configuration options ever available in an HTST control package.
The AV-9900 HTST recorder controller is specifically designed for use in continuous pasteurization applications. The unit combines failsafe protection for the pasteurization process with the broadest range of configuration options ever available in an HTST control package. This is accomplished via a unique, four color printing technology which prints on plain paper. 12', 100 division charts. Each unit is programmable for up to 4 independent recording ranges and input types. Each scale is color coded to its' trend pen to provide a chart that is simple to read, even with multiple variables.
The standard unit provides legal Safety Thermal Limit Recorder (STLR) functionality with up to 5 selectable diversion setpoints. Remote selection of these setpoints is available as an option. Product temperature is monitored via our time proven dual element, 1,000 ohm RTD sensor. The STLR monitors sensor balance between the two elements to insure failsafe operation. The hot product scale, temperature, and flow diversion valve frequency trend are printed in red. When configured for multiple divert, the activated setpoint temperature is continuously printed in green.
The unit can be optionally specified to include hot water control (HWC). This variable is normally displayed and controlled, but not recorded. For multiple divert applications, separate hot water setpoints can be programmed to be selected automatically when the diversion setpoint is changed.
Cold product can be optionally specified for Recording (CPR), or Recording/Controlling (CPRC). The range for this function is programmable to provide maximum readability in the product range while including CIP temperature. The standard color for this variable is blue.
Now available with a Safety Flow Limit function for systems with meter based timing. This option can include Recording (SFLR) or Recording and Control (SFLRC). Range can be configured in percent flow or engineering units (GPM etc.)- The standard color for this function is black.
