Condition audit

By performing a Condition Audit, our specialists can find out the state of the equipment in terms of mechanical condition, cleaning requirements, or repair needs.

Condition audits include checking:

  • Frame and bolt condition
  • General plate condition
  • General gasket condition
  • Spare parts inventory
  • Gasket lifetime prediction*
  • Detailed plate condition including plate deformation test *
  • Detailed plate condition including connection linings*
  • Fouling evaluation*
    *For not-in-operation audit

Visual condition assessment



Thanks to our unmatched heat exchanger expertise, Alfa Laval can perform a visual inspection of your gasketed plate heat exchanger while it is in operation. Using infrared camera technology, we also evaluate the actual heat transfer performance of the heat exchanger. We then provide you with recommendations based on our findings and analysis of the thermal images.

Visual Condition Assessment includes checking:

  • Condition of frame parts
  • Plate condition
  • Gasket condition
  • Thermal performance

Performance audit

With Performance audit, our field service experts can verify if your plate heat exchanger is performing according to design specifications and help identify areas where performance can be improved.

Performance audits include:

  • A visual inspection of the installed equipment
  • Data collection, including temperature differentials and flow rate on the actual operating condition
  • Performance benchmarking to derive heat exchanger’s optimal heat load
