More info

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.


  • New four color recording technology prints all trends, scales, events and customer specific messages on a plain paper, 12” chart.
  • Hot product, cold product, hot water, and flow-rate all recorded and/or controlled in a single unit.
  • Meets all PMO requirements for HTST, HHST, and UHT applications..
