Electronic Industry – clean rooms

Electronic Industry CEMAT’70 and Institute of Electronic Materials Technology – replacement of two large air handling units with new AHUs; accurate temperature and humidity control.

Existing AHU units were far past the end of their service live, with inefficient single speed fans and manually operated controls. Filtration quality was questionable. Temperature and humidity control was poor and unreliable.

New systems featured:

  • New AHUs
  • Variable speed fans for constant air flow
  • High efficiency fans and motors
  • Filter pressure drop controls
  • High efficiency, low pressure drop filters
  • Activated Carbon filter for SO2 removal from the supplied air
  • High efficiency pumps and motors
  • DDC controls with accurate temperature and humidity control
