The standardised configurations in the Flexitherm Core range are designed to cover the vast majority of normal pasteurisation capacity requirements between 40 and 400 hl/hour.
Each configuration is optimized to efficiently deliver a constant pasteurisation effect (selectable from 10–100 units) at variable flow, based on the following operating conditions:

  • Product inlet/outlet temperatures and pressures of 2°C and 200 kPa, respectively
  • CO2 content up to 6.0 g/litre
  • Pasteurization temperatures of 67–76°C
  • Holding time of 30 seconds at maximum capacity.

Pre-engineered advantages
Each Flexitherm Core module is a self-contained pasteurization unit that is pre-configured, pre-assembled and factory tested before delivery. These modules – conceived on the basis of “keep it simple” thinking – provide cost effective, pre-engineered solutions that ensure uncompromising performance and quality at relatively limited cost.


Flexitherm Core modules provide you with many clear-cut benefits:

  • Stable product treatment even during variable flow
  • Capacity turndown of up to 50% from the nominal
  • Reliable PU control system that ensures consistent pasteurization
  •  Very low energy consumption
  • Standardized plug-in design ensures quick, on-time delivery
  • Pre-assembly and factory testing of the frame-mounted module
  • Exceptional reliability and low maintenance requirements, keeping downtime to a bare minimum
  • A state-of-the-art automated control system provides exceptional production efficiency and minimizes production losses
