Design Options

Double Wall Plate System

  • Minimizes risk of fluid cross-contamination.
  • Two stainless steel walls within a combined plate, with an air gap in between, separate the fluid streams. In the event of a leak, the affected fluid will flow into the air gap and escape out of the heat exchanger, enabling visual detection of the leak.

Multi-Section Design

  • AX-Line sanitary gasketed plate heat exchangers are available as multi-section solutions – multiple heat exchangers combined into a single installation, divided by intermediate frames.
Plate Block Heat Exchangers

Available with both Fishbone and Free Flow plates, the AX-Line provides advanced heat exchanger engineering solutions for hygienic applications.

Features and Benefits
  • Accessible construction design for quick and trouble-free inspection, maintenance, and cleaning, including cleaning in place (CIP).
  • Sturdy nylon rollers make the movable cover slide open effortlessly, and locking bushings with ball bearings allow it to be closed tightly again.
  • Connections from DN25 to DN800 (1″ to 32″).
  • Plate heights up to 3.5 m (11.5 ft).
  • Flow rates up to 1,600 m3/h (7,045 gpm).
  • Regenerative pasteurizers recycle up to 95% of the energy.
