New Low Humidity ISO Class 7 Cleanroom

Callidus Design Limited were appointed by Stirling Medical Innovations (now known as Alere Technologies Ltd) as lead designer to design a new Low Humidity, ISO Class 7 Cleanroom (Class 10K) facility within their existing building. The facility allowed SMI to commence prototype production of a new medical device which they had recently developed. The works involved the design of a new HVAC system which was capable of operating over a wide range of temperature and humidity setpoints. This flexibility essentially provided SMI with an environmental chamber, the conditions of which could be varied over a wide range in order to test the stability of their product in varying environmental conditions. Callidus Design Limited were responsible for the design and specification of the following services:


  • Supply and recirculation ventilation installation
  • Fresh air ventilation installation
  • Dedicated chilled water installation
  • Dedicated LTHW heating installation
  • RO Water installation
  • Clean dry air installation
  • Fume exhaust installation
  • Domestic water installations
  • Drainage installations
  • Lighting installation
  • Small power installation
  • Fire alarm installation
  • PA installation
  • Security installation
  • Controls installation


In order to accommodate the plant associated with the new cleanroom, a new dedicated plantroom had to be carefully configured within the confines of a small site.
