Daikin adds high-temperature heat pump
16th June 2025
ITALY: Daikin is to introduce a new high-temperature option for its VZ series of water-to-water heat pumps, capable of supplying hot water at temperatures up to 90°C.
By extending the operating envelope, Daikin says 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.
The Daikin EWWH-VZ water-cooled inverter chiller and heat pump offers a cooling and heating capacity ranging from 400kW to 1900kW.
By separating the electrical panel from the main body, the EWWH-VZ is said to provide greater versatility in system design and layout, facilitating easier access for maintenance and optimising the use of available space, particularly in retrofit projects.
The EWWH-VZ employs single screw compressors with variable volume ratio (VVR) technology. 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.
System reliability is enhanced by the use of the Intelligent Chiller Manager (iCM), Daikin’s advanced control solution designed to optimise the performance of multi-unit systems.
