In 2001, the Mauritius Commercial Bank Ltd decided to replace the two air cooled chillers located on the roof of its MCB Centre at Sir William Newton street in Port Louis, Mauritius.

The existing chillers were not in good condition and the maintenance costs were getting prohibitive. With the rising cost of electricity, it was decided to take this opportunity to reduce the rating of the chillers through the installation of a TES with an advanced control system, to be able to take advantage of future off peak reduced tariffs announced by the Central Electricity Board.

At the end of 2002, a “Cristo’Pak” with associated “Cristo’Control” using the latest communication technologies (remote management, e-reporting and preventive maintenance) was installed and this enabled the installation of two new chillers of nominal capacity 470 kW in replacement of the existing 750 kW chillers. The installation was commissioned in early 2003.

The Cristo'Control is able to optimize automatically the use of the Thermal Energy Storage (STL) according to the real cooling demand and to control the installation by remote management. In addition, the performances of the installation can be followed by Internet and the electrical consumption is measured.
