Tokyo, October 23, 2017 - Mitsubishi Heavy Industries, Ltd. (MHI) is integrating two of its Group companies - MHI Thermal Systems, Ltd. and MHI Automotive Thermal Systems, Ltd. (MCCJ) - effective January 1, 2018. Through consolidation of technologies and resources in air-conditioning & refrigeration (AC&R) and automotive air-conditioning systems, MHI looks to strengthen its global competitiveness while also focusing on building more resilient management. The integration forms part of MHI's wider business reorganization initiative, targeting scale expansion and enhanced operational efficiency.

MHI Thermal Systems was established in October 2016, MCCJ in January 2013. The two companies will be integrated via absorption-type split to form a successor company which will retain the MHI Thermal Systems name.
