Fluorine Characteristics Help Miniaturize the Size of Film Capacitors

We also conduct research and development into use of the high-dielectric properties of fluoropolymers that help miniaturize the film capacitors used in power conditioners and other such equipment.

Daikin Sells New R-407H, Refrigerant with 62% Lower Global Warming Potential

Daikin develops and sells R-407H refrigerant for freezers and refrigerators, which has an approximately 62% lower global warming potential (GWP) than R-404A, the refrigerant commonly used today in freezers and refrigerators. R-407H is being adopted mainly in European markets.

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 9 Series 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 2018, we released some of the models in the oil cooling unit lineup in a water-cooling type. In general air-cooling-type Oil Cooling Units, waste heat from the unit creates heat inside a factory, but with cooling water, wastewater is discharged to outside the factory. In fiscal 2019, we expanded our lineup of water-cooling type products and added immersion-type products for cooling small- and medium-sized coolants to our lineup.
