When To Open Your Heat Exchanger

A plate heat exchanger maintenance and inspection schedule is dependent on many factors including environment (time, temperature and concentrations), frequency of use, and, in some cases, a mandate from a regulatory agency.

Different industries have different maintenance requirements, and different processes have different effects on your heat exchanger. It is always best to establish a preventative maintenance schedule to maximize up-time. 

Some reasons why you would open a heat exchanger are:

  • Visual inspection C ensure a clean in place process is working
  • Cleaning C Some industries do not clean in place and require a manual cleaning
  • Change plates and or gaskets
  • Internal leakage

General PHE Maintenance

Regular maintenance will help ensure that your plate heat exchanger stays sanitary and operational. Regular PHE service procedures generally include: 

  • Pre-teardown: Valving off unit, draining of fluids, disconnection of pipes, verification of plate pack arrangement, and primary leak/contamination tests 
  • Teardown: Loosening of tie-bolts, disassembly of unit
  • Cleaning: Gasket removal (if possible), plate cleaning
  • Inspection: Start/flow gasket inspection and replacement as needed, plate inspection, frame and component inspection
  • Reassembly to previous, exact configuration and optimal tightening of plate pack for maximum reliability and performance. 
  • Verification of unit functioning as desired.
