The controllers of centrifugal chillers manufactured by Mitsubishi Heavy Industries Thermal Systems, Ltd. are proprietary products of MTH. However, it was impossible to replace existing controllers with the latest ones due to the significant difference between old and new controllers and the difficulty in ensuring compatibility. Nevertheless, many centrifugal chillers that were released more than 10 years ago and are equipped with old controllers are still in service and they will continue to be used for a long time in the future. In order to reassure our customers that they can operate MTH centrifugal chillers for a long time without issue, we have developed a renovation controller with the latest features compatible with older controllers.
