Optimizing Machine Tools to Achieve Both Energy Efficiency and Environmental Compliance

The European machine tool industry is currently at a major turning point.

In addition to improving productivity, compliance with environmental regulations—particularly the F-Gas regulation (GWP below 150), which will come into force starting in 2027—has become an essential requirement in machine design.

Furthermore, the sharp rise in electricity costs caused by global instability has made energy optimization throughout the entire equipment lifecycle more important than ever.

In this market environment, the two Daikin Group subsidiaries, Duplomatic MS SpA and Daikin Fluid Technology GmbH, offer solutions that combine energy efficiency and environmental compliance through advanced hydraulic and thermal management technologies.

In hydraulics, Duplomatic MS offers the ECORICH energy-saving hydraulic unit, featuring Daikin inverter technology. In thermal management, Daikin Fluid Technology provides AKL Series inverter chillers using the low-GWP refrigerant R454C, together with Deltatherm customized chillers, trusted by European machine tool manufacturers for decades.

Together, these two pillars—hydraulics and thermal management—deliver optimal solutions for the next generation of machine tools.

These technologies will be showcased at AMB 2026, taking place in Stuttgart from 15 to 19 September, where Duplomatic MS and Daikin Fluid Technology will present their integrated Motion Control and Thermal Management solutions – Hall 8, Stand 8D70.

Energy-Saving Hydraulic Unit "ECORICH"

Duplomatic MS offers Daikin's ECORICH, an innovative hydraulic unit equipped with an inverter-controlled IPM motor.

Compared with conventional induction motor systems, ECORICH significantly reduces energy consumption while automatically adapting operation to the machine load, minimizing unnecessary power usage.

Its low heat generation and high-efficiency design reduce oil temperature rise, improving the machine's thermal stability. This contributes to:

• Higher machining accuracy
• Longer hydraulic oil life
• Lower cooling demand
• Reduced operating costs

The inverter drive also provides excellent responsiveness, minimizing pressure and speed fluctuations while ensuring stable actuator control for precision machining.

Its compact footprint allows easy integration into modern machine tool designs.

Next-Generation R454C Chiller – AKL Series

Selecting the right refrigerant has become a critical factor for compliance with the upcoming F-Gas regulations.

Leveraging Daikin's expertise in developing both compressors and refrigerants, Daikin Fluid Technology GmbH offers the AKL Series, featuring the low-GWP refrigerant R454C.

With a GWP of only 148, R454C represents an ideal solution for future environmental requirements.

Beyond regulatory compliance, the AKL Series delivers:

• High energy efficiency
• Precise inverter capacity control
• Reduced power consumption
• Stable cooling performance

Daikin's proprietary compressor technology and advanced control algorithms ensure both high reliability and accurate temperature control, making the AKL Series ideal for spindle cooling, coolant management and other machine tool applications.

Deltatherm Chillers – Over 55 Years of European Expertise

Since 1971, the Deltatherm brand, now Daikin Fluid Technolgy GmbH (DFTG) has been supplying temperature control solutions to European machine tool manufacturers.

Its strength lies in highly customized solutions, supporting:

• Complex piping layouts
• Multi-circuit cooling systems
• High-flow applications

In recent years, Daikin Fluid Technology has progressively transitioned the Deltatherm range to R454C refrigerant, combining environmental compliance with the flexibility required by OEMs.

Its capability to engineer tailor-made solutions for non-standard applications continues to be one of its greatest competitive advantages.
