Cecchina, July 2025 – Daikin introduces a new high-temperature option for its VZ series, using the R-1234ze refrigerant to expand the operating range of existing models. This enhancement enables the unit to supply hot water at temperatures of up to 90 °C, making it suitable for a wider variety of applications.
Unit features
The Daikin EWWH-VZ water-cooled inverter chiller and heat pump combines exceptional energy efficiency with low environmental impact. Using R-1234ze, a refrigerant with a very low Global Warming Potential (GWP) of 1.4, it offers a cooling and heating capacity ranging from 400 to 1,900 kW*. Thanks to its compact design and inverter technology, the unit ensures optimal performance and flexibility to meet a variety of operational needs. The introduction of this new option is a significant step towards decarbonising industrial heating. By extending the operating envelope, the EWWH-VZ series is well-suited to a variety of applications, including industrial processes and district heating networks, where high-temperature hot water is essential. This feature is particularly useful for industrial processes that require water at a high temperature for cleaning, sterilisation or production purposes.
6 reasons to choose the Daikin EWWH-VZ high-temperature water sourced heat pump
1. Sustainable industrial processes and district heating systems
In line with the European targets for reducing fossil fuel consumption, there is a growing demand in the market for high-temperature heating solutions. In this context, the Daikin EWWH-VZ unit's capability to deliver hot water at temperatures of up to 90°C is particularly significant. It plays a pivotal role in decarbonising industrial processes and district heating systems, which have traditionally relied on fossil fuel-based boilers. Unlike conventional systems, the EWWH-VZ operates without combustion and uses a low-GWP refrigerant, which significantly reduces CO₂ emissions.
Thanks to its inverter technology and high energy efficiency, it also offers a more sustainable and cost-effective alternative to traditional boilers, helping industries and communities for their transition towards more energy-efficient heating solutions.
2. Flexible installation
One of the EWWH-VZ unit's key strengths lies in its exceptional installation flexibility, making it ideal for limited spaces. This is made possible by the innovative knock-down electrical panel, which can be installed up to five metres away from the main unit. This feature allows installation in even the smallest technical rooms – perfect for replacing gas boilers. By separating the electrical panel from the main body, Daikin provides greater versatility in system design and layout, facilitating easier access for maintenance and optimising the use of available space, particularly in retrofit projects.

3. Efficient technologies
In terms of efficiency, the EWWH-VZ is equipped with Daikin’s advanced single screw compressors featuring variable volume ratio (VVR) technology. This innovation enables the compressor to automatically adjust the internal volume ratio according to the unit’s operating conditions, thereby maximising compression efficiency in all operating conditions.
To further enhance performance, the system incorporates inverter technology, also referred to as a variable frequency drive (VFD). This electronic component regulates the compressor’s rotational speed (RPM) by varying the frequency of the power supply. Consequently, the compressor can adapt its capacity continuously to match the actual heating or cooling demand. This combination ensures the EWWH-VZ delivers high efficiency, precise capacity control and reliable operation under a wide range of conditions, making it a smart, sustainable choice for industrial and commercial applications.
4. Reliable heating system
The single screw compressors featuring variable volume ratio (VVR) technology also ensures maximum reliability. This system includes a mechanical adjustment mechanism that modulates the volume of the discharge port, enabling the compressor to delay or anticipate the end of the compression cycle. This minimises under- or over-compression, lowering operating costs and enhancing long-term reliability. These benefits are particularly valuable in demanding industrial applications where performance and long-term durability are critical.
Another key contributor to system reliability is the intelligent chiller manager (iCM), Daikin’s advanced control solution designed to optimise the performance of multi-unit systems. The iCM coordinates the operation of each unit in the plant to ensure they work together efficiently, meeting demand with minimal energy consumption and mechanical effort. Finally, to further enhance operational continuity, Daikin may offer automatic transfer switches (ATS, upon demand). In the event of a power failure or outage, the ATS automatically switches the power supply from the primary source to a backup source. Once the primary source is restored, the system switches back, ensuring uninterrupted operation and protecting critical equipment.
5. Benefits of after-sales services
Daikin is a trusted partner in the HVAC industry, with years of experience in leadership and a strong track record in delivering customised solutions for any needs. With over 50 years' experience manufacturing across Europe, Daikin combines custom engineering expertise, local market knowledge and exceptional after-sales support. Production facilities around Europe ensure shorter lead times, lower transportation costs and faster delivery. Thanks to its widespread presence, Daikin can provide rapid and efficient on-site assistance whenever needed.
A key element of its after-sales service is Daikin on Site (DoS), a web-based, 24/7 remote monitoring platform that collects detailed operational data from units to control systems. This data is processed by Daikin experts who transform it into actionable insights. Users can monitor system performance remotely while Daikin experts optimise and maintain equipment in real time, reducing downtime and operating costs.
6. Ensuring performance peace of mind
To give customers complete confidence in their solutions, Daikin Applied Europe invites them to participate in witness tests – dedicated testing sessions that simulate the system’s real-world operating conditions. These tests provide tangible proof that the selected units meet the specific requirements of each project. Factory acceptance testing (FAT) is also available to verify that each unit complies with all design specifications and functional criteria before delivery.
