Mitsubishi Heavy Industries Thermal Systems, Ltd. (MHI Thermal Systems), a part of Mitsubishi Heavy Industries (MHI) Group, has launched sales in the domestic market of the TEJ35GAM, an electric-driven transport refrigeration unit exclusively for small and mid-size trucks. Ryoju Coldchain Co., Ltd. (RCC), the Company’s’ comprehensive sales and service arm for truck and trailer refrigeration units in Japan, will be in charge of the new product’s sales. The TEJ35GAM joins the already available TE20/30 series, refrigeration units for plug-in hybrid transport, and the TEJ35AM, an electric-driven transport refrigeration unit with heat-pump heating system for EV trucks. The TE20/30 series has received two notable awards: the “Agency for Natural Resources and Energy Commissioner’s Award (Transportation Field)” in 2019, and the “Technology Award” from the Japan Society of Refrigerating and Air Conditioning Engineers (JSRAE) in 2021.
TEJ35GAM Electric-Driven Transport Refrigeration Unit
The new TEJ35GAM features a plug-in hybrid system combining a commercial plug-in power source and a power source dedicated to the refrigerator. The system can automatically switch between plug-in charging and battery operation charged while running, depending on the status of vehicle operation (idling, running, etc.). Additionally, the system automatically switches to one of three modes (power save, high efficiency, full capacity) depending on the refrigerator battery’s remaining charge volume and the cargo room temperature. Because operation of the refrigerator continues even while the vehicle is parked or idling, the driver can focus on driving and delivery without having to operate the refrigerator, and outstanding cargo temperature control is achieved.
The TEJ35GAM also adopts heat-pump heating, in which ambient heat is used for heating operation, and a multi-system that enables multiple temperature settings appropriate to the specific cargo volume or type. Together these features enable simultaneous cooling and heating of two cargo rooms, a capability not possible with a conventional hot-gas heating system. The result is stable temperature maintenance throughout all four seasons: cooling of both cargo rooms in summer, powerful heat-pump heating of both cargo rooms in winter, and simultaneous independent cooling and heating of the two cargo rooms in spring and autumn. For the greater part of the year – the only exception being summer, when heating is not used – heat-pump heating also results in highly efficient operation with an excellent COP*.
In the years ahead, MHI Thermal Systems will continue focusing on the development of technologies and products that will contribute to reducing CO2 emissions and saving energy by taking advantage of advances in electric-driven transport refrigerator inverter control, heat-pump systems, multi-systems, etc. Through such new developments, the Company will address distribution industry issues relating to workstyle reform, transport efficiency enhancement and environmental performance, to realize safe and secure food transport.
*Coefficient of Performance (COP) is an indicator of the degree of efficiency that can be realized from using one kilowatt of electricity. Larger values indicate greater energy efficiency. For refrigeration systems, COP is the rated refrigeration capacity (kW) divided by electricity consumption (kW).

Mitsubishi Heavy Industries Thermal Systems, Ltd. (MHI Thermal Systems), a part of Mitsubishi Heavy Industries (MHI) Group, has developed a new electric-driven transport refrigeration unit exclusively for electric vehicles (EVs), the TEJ35AM, which is equipped with a heat-pump heating function. Sales of the new unit will be launched for use in production model EV trucks made by domestic automakers. In contrast to conventional systems in which the transport refrigeration unit is powered by the vehicle’s engine or a dedicated refrigerator engine, the TEJ35AM features an electric drive system that enables operation driven by electric power from the EV alone.
The adoption of heat-pump heating, in which ambient heat is used for the heating operation, enables the TEJ35AM to perform heating and cooling operations simultaneously. With this dual capability, the heating mode prevents cargo freezing when the outside temperature is low, and the cooling mode prevents food and other cargo from deteriorating in quality when the outside temperature is high. The unit also features a multi-system that enables multiple temperature settings appropriate to the specific cargo volume or type. This enables the TEJ35AM to accommodate diverse transport modes, including simultaneous transport of products requiring multiple temperatures, to meet the needs of convenience stores and the like. Furthermore, because the refrigeration unit can be operated under all vehicle operating conditions – when running, stopped or charging – the temperature inside the cargo room can be kept stable at all times, ensuring safe transport of food items.
The TEJ35AM saves energy through the adoption of a high-efficiency heat-pump system which not only cuts energy consumption but also reduces carbon emissions, and in this way it responds to the needs of automakers undertaking development of EV trucks as a contribution to the quest for a carbon neutral society. Going forward, availing of the ability to combine the unit with various power supplies, the TEJ35AM will be promoted for installation in EV trucks, whose proliferation is one target of the Government’s “Green Growth Strategy.”
In the years ahead, MHI Thermal Systems will continue focusing on the development of technologies and products that will contribute to reducing CO2 emissions and saving energy – not only in the transport refrigeration units business, but also its businesses in thermal engineering targeting enhanced energy efficiency in plants of all kinds, large-scale refrigerators for expansive spatial cooling, air-conditioners to create comfortable spaces of all kinds, and automotive air-conditioners. In these and other ways, the Company will dedicate its resources to the realization of optimal thermal solutions to meet the diverse needs of its customers.

Mitsubishi Heavy Industries Thermal Systems, Ltd., a part of Mitsubishi Heavy Industries (MHI) Group, will launch 22 new models of residential-use air conditioners for the Japanese market for 2023. The new models in three series will be successively released starting April 1. The 2023 lineup comprises nine models in the Company’s top-of-the-line S Series, featuring outstanding energy efficiency, functions for comfort and cleanliness, and a high Annual Performance Factor (APF), six models in the high-performance R Series incorporating an automatic filter cleaning function, and seven models in the standard T Series. Together these new models provide comfortable living spaces for diverse lifestyles.
Features of the New Models
1. Two types of sensors, and functions using ions and ozone provide comfort and cleanliness (S Series) 1) A comfortable environment provided by two types of sensor (motion and thermal sensors) The incorporation of a motion sensor to detect the movement of people, and a thermal sensor to detect the location of people and changes in the temperature of walls or floors, allows for an “AI Automatic Comfort” operating mode in which AI utilizes information from the sensors to automatically optimize comfort and energy efficiency, as well as a new “Sensor-Guided Airflow” and “Breeze Direction” operating mode to automatically adjust the direction of the airflow. 2) A clean environment provided by functions using ions and ozone The cleanliness of the indoor unit has been enhanced with such features as a “Refreshing Ion Mode” that releases negative ions to inhibit the proliferation of viruses, bacteria, and mold, an “Aqua Ozone Mode” that floods the indoor unit with ions and ozone to inhibit the growth of odor and dirt-causing bacteria, and a “Aqua Ozone Heating Mode” that uses heated-air drying to inhibit the growth of mold bacteria.
2. High APF and exceptional low temperature heating performance (S Series) The incorporation of a new compressor with a greater number of copper windings and a high-grade neodymium magnet, a new invertor with high-efficiency pulse amplitude modulation (PAM) control and low-loss switching element, larger diameter fans for the indoor and outdoor units, and a high-efficiency motor, has increased the energy efficiency performance by around 14% compared to previous models. These models also fully demonstrate their capabilities when the outside air temperature drops, with low temperature heating performance enhanced 29% compared to previous models.
3. Compatibility with smart speakers for improved operability (All series) The wireless LAN interface that had been previously offered as an add-on option is included as a built-in unit on S Series models, allowing these units to be controlled with a smartphone without altering the external appearance. The operability of all new models has also been improved with the capability of linking them to a smart speaker (sold separately) to provide voice-activated control or confirmation of the operating status.
4. The lineup of 22 models in three series provides comfortable spaces for diverse lifestyles Continuing from the 2022 models, all three series have a “WARP” operating mode enabling rapid cooling or heating, an extra-powerful “JET Airflow” operating mode, and a “Bio-clear” operating mode in which temperature and humidity near the filter is controlled to suppress pollen with enzymes and urea in the bio-clear filter.
In addition, the indoor units in the R Series and T Series are of compact dimensions, with a height of only 25cm, allowing for installation even in tight spaces such as above tall windows or below clipped ceilings.
As with the 2022 models, the S Series and R Series are equipped with a function allowing linked and synchronized operation with the “roomist” SHK Series of hybrid evaporative warm-mist humidifiers from MHI Group firm Mitsubishi Heavy Industries Air-Conditioning & Refrigeration Corporation, allowing for optimal control of the temperature and humidity.
Further, all series contribute to environmental conservation with the use of filter holders made from a synthetic resin containing recycled tea leaves, an upcycling of tea leaves using the Tea Leaves Recycling System developed by Japanese beverage company ITO EN, Ltd.
