Private client requested an AHU modification for 68kW DX cooling

We retrofitted several 10 year old fresh-air-only air handling units for two critical uninterrupted power supply rooms.

Each unit was to be stripped off its existing motor and fan scroll to be replaced by an EC fan which was to be controlled by the BMS. We also added a DX coil allowing up to 76kW of cooling from a Daikin VRV system and its associated components.


  • Installed x2 68kW DX cooling systems in two data halls

  • Only permitted to turn off one unit out of four at any time

  • RAMS issued for the project and schedule issued on site

  • Hiab used to lift x8 Daikin Condensers and x4 EF fan motors

  • Completed in three phases

  • All materials were delivered to site


The project management, design,  installation, commissioning and testing was completed as a turnkey project under which we managed multiple subcontractors.

We brought the project in on time and budget and during the project washup the feedback from the customer was overwhelmingly positive, with particular praise given to the Klimatec project manager for his time and attention to detail throughout.
