For all types of refrigeration equipment HOS BV uses various test protocols and quality standards.

How we test an industrial refrigeration evaporator:

  • Fans are tested electrically and mechanically and if necessary worn bearings will be replaced
  • For a certain range of evaporators new electrical defrosting elements can be fitted if required and not present yet.
  • Next the coil of the evaporator is pressurized to test for internal leakage (with nitrogen for freon and ammonia evaporators, with pressurized air for Glycol evaporators)
  • After all testing evaporator gets released for industrial cleaning
  • If necessary and agreed upon with customer visual touch-up work can be done
  • Evaporator then gets packaged for safe transport
