Home air conditioner
The "Eolia" X Series room air conditioners are designed to deliver high efficiency and stable operation even under low-load conditions, addressing the increasing use of residential air conditioners driven by improved home insulation performance and climate change.
Our research indicates that air conditioner usage has increased throughout the day and across seasons. In particular, energy efficiency during low-capacity operation—such as in spring and autumn, as well as during nighttime—has become increasingly important. In response, we developed an "Eco Inverter Control" system that enhances airflow and compressor control, along with an "Eco Rotary Compressor" that improves operational stability under low-load conditions.
In addition, this new energy-efficient room air conditioner incorporates a partial dehumidification function that prevents overcooling while reducing energy consumption, as well as a propeller fan with auxiliary blades that achieves both lightweight, resource-saving design and improved performance.

Absorption Chiller "Energy-Saving Natural Chiller, Type PR Genelink"
An absorption chiller is an air conditioning system that uses the heat of vaporization of refrigerant under vacuum, without using a compressor. The chiller uses water as the refrigerant and thermal energy as the operational power source such as the waste heat from factories and the combustion heat of gas. Therefore, the chiller is suitable for air conditioning for large-scale facilities such as domed stadiums, as air conditioning equipment that is environmentally friendly because of low power consumption. The system has large advantages that it is possible to lower the electric power load peak when the cooling load is high, that it uses water as a natural refrigerant, and that the outdoor unit installation space required is smaller than the one required for other air conditioning facilities of a similar capacity.
Compared with conventional products, this chiller reduces the rated cooling water flow rate by 30% and the cooling water pump conveyance power by 65.7%. This reduces the electric power consumed by the cooling water pump, which is a unit that consumes a large amount of power, minimizing it as far as possible. Furthermore, the 23.5% reduction of gas combustion through the utilization of waste heat indicates that energy-saving has been realized. These reduction were favorably evaluated for the product as a whole and it received the Promotion Award of the Heat Pump & Thermal Storage Technology Center of Japan in the 2017 Demand-Side Management Awards.

IAQ controlled heat exchanger system
A heat exchange ventilation system equipped with "IAQ (Indoor Air Quality) control" contributes to energy savings throughout the year by reducing air-conditioning loads through heat-exchange ventilation in summer and winter, and by lowering ventilation power consumption through automatic adjustment of air supply and exhaust volumes during mid-season periods.
During peak summer and winter periods, when air conditioning operates at full capacity, the system recovers heat from exhaust air and supplies it at a temperature closer to the indoor environment. This reduces the cooling and heating load on air conditioners, maintaining indoor comfort while improving energy efficiency.
During intermediate seasons (spring and autumn), when indoor temperatures are comfortable and air-conditioning demand is low, the system senses the temperature difference between indoor and outdoor environments and adjusts ventilation air volume according to air quality. This enables energy-efficient ventilation operation. For example, when heat exchange is less necessary, exhaust volume is reduced to lower power consumption.
In addition, maintaining a positive indoor pressure—where the air supply volume exceeds the exhaust volume—helps mitigate the ingress of outdoor pollutants, such as pollen and PM2.5, thereby preserving indoor comfort.
Furthermore, DC motors with low specific power consumption (high operational efficiency) are used for both supply and exhaust fans. These motors work effectively with variable airflow control, contributing to further reductions in the power consumption of the ventilation system itself.
In this way, the heat exchange ventilation system with IAQ control suppresses energy loss from ventilation and helps reduce daily electricity consumption, thereby contributing to lower CO₂ emissions. It is a ventilation system that achieves both comfort and energy efficiency / environmental consideration, and offers strong compatibility with GX-oriented (green transformation) building design.

Residential fuel cell unit 'Ene Farm'
'Ene Farm' residential fuel cell unit is a system that provides high efficiency for power generation and energy saving benefits. 'Ene Farm' extracts hydrogen from city gas (natural gas) or LP gas, and then chemically reacts the extracted hydrogen with oxygen in the air to generate electricity. The heat generated by the reaction is stored in a hot water storage tank and can be used at home.
All of 'Ene Farm' units are equipped with the LPWA (Low Power Wide Area) communication function as standard that enables receiving weather information through cloud. In the case that 'Power Outage Risk Prediction' is received, its power generation mode is automatically switched to be prepared for power failure. Even in the event of a power failure at midnight or other times when the 'Ene Farm' has stopped generating electricity, there is no need to restart the 'Ene Farm' with an external power source. Therefore, 'Ene Farm' users can use electricity without worrying even in the event of a power failure.
In addition, for the case that the gas supply is stopped, a new function is equipped to boil water using its electric heater. Moreover, when the water supply is cut off, the hot water in its hot water storage tank can be used as domestic water. Thanks to these features, with one 'Ene farm' unit, it facilitates securing the minimum necessary infrastructure in the event of a disaster, such as 'electricity in the event of a power outage', 'hot water in the event of a gas supply stop', and 'domestic water in the event of a water outage'. Therefore, 'Ene Farm' users can spend time at home without worrying even when they are forced to sheltered at home.

Industrial Inkjet Equipment for Low-Cost, High-Definition Organic EL (OLED) Displays
Organic EL (OLED) displays, in which red, green, and blue (RGB) light-emitting materials are coated on a substrate and an electric current is applied to the substrate to project images, are widely used in society such as televisions, smartphones, and signage.
Traditionally, vacuum deposition has been used to manufacture OLED displays, but the material utilization efficiency is very low, and most of the expensive materials are discarded. Compared to vacuum process equipment, our company's inkjet system can improve the material utilization efficiency with less expensive equipment, and it can be used for large substrates. Furthermore, since printing can be performed without vacuum, it can also save energy when manufacturing OLED displays. In addition, since displays produced by inkjet equipment lose less light through color filters due to RGB spontaneous emission, it has the advantage of higher energy conversion efficiency than displays produced by vacuum deposition, which is used for conventional white OLEDs, and it can also save energy when using OLED displays.
This technology has been highly evaluated from the perspectives of scientific and technological progress and industrial development, and has received numerous awards, including the Ichimura Industry Award for Achievement and the Okochi Memorial Technology Award.
Low Power-Consumption Turntable-Type Sputtering System to Reduce Cleanroom Operating Costs
Sputtering systems, which deposit thin-film materials onto substrates in a vacuum environment, are widely used in front-end manufacturing processes for semiconductor devices, displays, energy products, and optical components.
Conventional sputtering systems typically employ a multi-chamber configuration to enable continuous processing of different materials within a single system. However, this approach increases the equipment footprint, leading to higher cleanroom operating costs.
The Company's turntable-type system addresses this challenge by incorporating multiple processing chambers within a single vacuum chamber and transferring substrates between them using a turntable mechanism. This configuration reduces the overall footprint and contributes to lower cleanroom operating costs.
Furthermore, by consolidating multiple processing chambers into a single vacuum chamber, the number of cryopumps required to achieve high vacuum conditions can be reduced. This leads to lower energy consumption by the compressors that drive the pumps, thereby contributing to improved energy efficiency during equipment operation.
The Company's sputtering systems are highly reliable and compatible with multilayer film processes that have been widely adopted as industry standards over many years. As such, they are also highly regarded as a B2B platform.
Ultra-High-Speed H&C Molding (Electric Type) Featuring Low Cost and Short Cycle Time
H&C (Heat & Cool) molding is widely used in automotive and home appliance applications to achieve weld-less and paint-less finishes. Steam-based H&C molding, a type of molding process for materials such as plastics, performs both heating and cooling within a single molding cycle. This contributes to superior surface quality and reduced molding difficulty; however, it has the drawback of longer cycle times.
The Company's proprietary ultra-high-speed H&C molding (electric type) overcomes this challenge by combining a high-efficiency electric heater for the heating process with advanced heat exchange technology that enhances cooling efficiency using chiller water. This innovation significantly shortens the H&C process cycle time, enabling a reduction in the number of molding machines required and lowering processing costs, thereby contributing to energy savings.
In addition, the elimination of boiler equipment reduces both material usage and fuel costs, further lowering environmental impact from the perspectives of resource efficiency and energy consumption.
