Mitsubishi Heavy Industries (MHI) Group companies – Mitsubishi Heavy Industries Thermal Systems, Ltd. (MHI Thermal Systems) and Mitsubishi Heavy Industries Asia Pacific Pte. Ltd. (MHI-AP) – have jointly delivered two large-capacity centrifugal chillers for a large-scale district cooling system in Singapore’s Marina Bay as part of plans to expand the system. The two chillers, offerings in the “GART series”, have a collective cooling capacity of 8,400 refrigeration tons (RT). and will bring the total number of centrifugal chillers provided by MHI Group to the Marina Bay area to 18.
The GART-400PLS.SCF model centrifugal chillers each have a cooling capacity of 4,200 RT, the largest capacity of all units delivered to the Marina Bay district cooling system to date. The new units can accommodate the HFO-1234ze(E) refrigerant, which is recognized for its extremely low environmental impact: a global warming potential (GWP) below 1. In addition, the GART-400PLS.SCF chillers have a near 6% higher rated coefficient of performance (COP and approximately 10% higher integrated part load value (IPLV) than earlier models, enabled by the adoption of a tandem operating configuration resulting in reduced energy consumption. Carbon emissions can also be cut by 9%.
Undergoing continuous expansion, the system will service a total of 28 buildings by 2026 and will reduce approximately 20,000 tonnes of carbon emissions per year.
MHI Group was awarded the order based on its technological strength and after-sales servicing capabilities, as well as the environmental performance, economic benefits and high reliability of its centrifugal chillers – as proven through its excellent delivery record.
