MITSUBISHI Heavy Industries (MHI) of South Korea has established a service and parts centre for refrigerated containers in Hong Kong. The establishment of the centre - MHI Hong Kong Reefer Service & Parts Centre - is part of MHI's effort to strengthen its service to shipowners. This is MHI's first marine transport refrigeration unit service and parts centre outside Japan. The main activity of the centre is to supply parts to Asian maritime transportation companies and shipowners in various countries, especially China. Early next year its Hong Kong office will expand its activities to include after-sales service support, after-sales service network supervision, technical consulting support and technical service seminars. By 1997 an after-sales service network will be launched in China to accommodate the growing market for marine transport refrigeration units there. China is expected to have the largest import and export markets for chilled and frozen cargo in future. Due to the increase in the worldwide distribution of vegetables, meats, seafood and products requiring refrigeration, the demand for marine transport refrigeration units has rapidly increased. Since marketing its first marine transport refrigeration unit in 1967, MHI has grabbed the biggest share in the worldwide market of maritime transportation companies, excluding marine container leasing companies. MHI manufactured more than 10,000 refrigeration units last year and expects to maintain the same production levels this year. MHI has also received firm orders from major shipping companies for delivery next year. MHI is also continuing its effort to develop environmentally friendly units. In 1990, MHI developed units using R22, in 1992, units using R134a to protect the ozone layer. In January next year, MHI is scheduled to produce a new unit using R404a to protect 'our one and only earth' from the effects of global warming. All models have interchangeable parts and components.
