Fluorochemical Products

Fluorine Characteristics Help Improve the Performance of Lithium-Ion Batteries

We offer gasket and binder materials that utilize the characteristics of fluorine for use in lithium-ion batteries. In addition, we are also undertaking development of binders that do not rely on solvents as a next-generation material which could lead to reduction of environmental impact.

As the use of renewable energy encouraged is seen in policies of each country and region globally, lithium-ion batteries as power storage system that is indispensable has attracted attention. Daikin aims to contribute to reduction in CO2 emissions through development and provision of outstanding materials.

Refrigeration Equipment Lineup with Lower Global Warming Potential Refrigerants

Daikin is gradually expanding product lineup of refrigerants with a lower global warming potential (GWP) than the R-404A refrigerants used in many conventional refrigeration equipment.

In addition to our R-407H refrigerant developed in-house, we also released the R-448A product manufactured by Honeywell International Inc. in Japan in 2020. In 2021, we plan to release R-455A, made by the same company, in Europe, which has cleared the GWP 150 or less stipulated by the European F-gas regulations. Additionally, we are also conducting in-house development of next generation refrigerants with zero GWP for air conditioners use.

Energy-Efficient Hybrid Hydraulic Super Unit
Energy Savings and Lower CO2 Emissions in Factories

Daikin also continuously pursues greater energy efficiency for hydraulic units for factory production lines.

The energy-efficient hybrid hydraulic Super Unit employs the same motor inverter technology that is used in Daikin's energy-efficient air conditioners. The Super Unit determines the load on the machine, depending on whether it is in standby, operation, or pressure holding mode, and electronically controls the pump at the necessary RPM. The result is energy savings of more than 50% in pressure holding mode (compared to Daikin piston pumps). For use on presses, vulcanizers, casting machines, and a wide range of other industrial equipment, it contributes to dramatic energy savings and lower CO2 emissions. We introduced new models and expanded the lineup in 2014. In 2017, we launched two for 37 kW models compatible with large machines that consume large amounts of power.

The Super Unit is widely used on industrial equipment around the world and has been highly rated for its superior precision and energy efficiency.

EcoRich Energy-efficient Hydraulic Unit
Helps Reduce Energy Consumption

EcoRich was developed in 1999 and was the world's first product to combine hydraulics technology and air conditioner motor inverter technology. It achieved approximately 50% lower energy consumption compared to Daikin's piston pump. In 2016, this product underwent a model change with the incorporation of high-efficiency IPM motor. Among its many features were a 30% decrease in energy consumption over the previous model and a 5°C reduction in oil temperature rise.

In 2018, we released a new EcoRich series, developed without a transformer, with 400 V specifications. It can be connected directly to power sources in Europe and China and does not require the installation of a transformer.

9 Series Oil Cooling Unit
Product Lineup Expanded to Meet Extensive Range of Needs

In machine tools, Daikin's Oil Cooling Unit makes possible detailed temperature control of the lubricating and cooling oil, which has a major effect on the precision of the work. Daikin's 9 Series Oil Cooling Unit allows temperature adjustment to ±0.1°C. In addition, with inverter control and the most advanced compressor, it offers 45% greater energy efficiency than conventional on/off controllers. In fiscal 2020, we left the 9 Series as is with its high energy efficiency, and released the 10 Series, a compact, light-weight, transformerless 400V model, and expanded our product lineup in fiscal 2021.

At the same time, we are also developing some models in the oil cooling unit lineup in a water-cooling type. This style of product eliminates heat outside of the factory using cooling water in order to eliminate waste heat from general air-cooling-type Oil Cooling Units inside a factory. We released some models in fiscal 2018, and in fiscal 2019, we expanded our lineup of coolant-cooling type products. Furthermore, in 2020, we also released products for oil cooling, as well as added more water cooling type products to our lineup.
