New plug & play water to water modular heat pumps

Daikin is announcing the release of a new range of water-to-water heat pumps: the EW*T-Q-X-A1 range, with Daikin design scroll compressors. These new water-to-water heat pumps are based on modular construction, increasing flexibility in configuration, and facilitating unit installation and transport.


The features

The new product features a new modular approach to system design, which introduces additional flexibility in configuration, allowing the required capacity to be reached by combining smaller units piped together and controlled as one. Among the benefits, modular construction offers several advantages in siting and installation, making units easier to transport, handle, and install up to a fully plug-and-play solution by including the Daikin Manifold Kit and Pump module.

Consisting of three base modules with capacities of 100, 125 and 160kW, the range features scroll compressors and is available in two sound levels, including a reduced sound version suitable for outdoor installation and noise-sensitive applications such as residential buildings, hotels, and hospitals. Unit configurations by type include the following:

  • Water to Water heat pump with inversion on the waterside

  • Water to Water heat pump with inversion on the refrigerant side (100 kW only)

  • Condenser-less


Extensive application and flexibility

The new modular scroll water-source heat pumps can provide heating or cooling in a variety of conditions, producing hot water up to +60°C and chilled water in a range from -15°C of the water-glycol mixture to +30°C of the water temperature at the evaporator outlet. As a result, a wide range of applications can be covered, including comfort heating, space and process cooling, and heat recovery.

The 5 benefits of modularity



Due to its modularity, the new Modular Scroll units offer high scalability potential, which reduces the initial investment costs and at the same time opens the possibility of future expansion by installing additional modules as building occupancy increases. In addition, the introduction of a common scroll layout ensures greater compatibility, promoting system longevity and making future system upgrades easy. Modules can be combined as a side-by-side array or stacked to minimise space requirements, particularly useful for retrofit applications.


Each of the different modules is very compact and can be easily transported and positioned in the installation space. As a single module measuring 120 cm wide, 130 cm deep and 100 cm high, it can be easily handled by a forklift truck, without the need for a crane to move an entire packaged chiller.

Plug & play installation

Installation can be further simplified by using the Daikin Manifold Kit, which is designed to connect modules on the waterside, as it includes the pipework between the units. In addition, each manifold is fitted as standard with manual isolation valves for all connections. This allows each module to be isolated from the circuit for maintenance without the need to shut down the entire system. In addition, a dedicated Pump Module can be easily added to the array of modules. It is equipped with inverter pumps for full flexibility and includes an 18-litre expansion tank.

Lower operating costs

Thanks to its modular design, this new unit can closely follow the cooling and heating load profile of the building. This is particularly important as it ensures low operating costs for the HVAC system at part load conditions, which represent most of the operating time. This is not the case with traditional packaged chillers, which are unable to deliver the load required by EN14825 at part load conditions. This means that the chiller would have to run a series of on-off cycles, introducing inefficiencies into the operation.

Delivering outstanding energy performance with limited environmental impact

This new solution is the result of Daikin's commitment to continuously improve the design to reduce the environmental impact of its cooling, heating and refrigeration solutions. The new modular scroll units are part of Daikin's BLUEVOLUTION range and use R-32 refrigerant, which has a Global Warming Potential (GWP) of 675, just one-third of R-410A. This, combined with its high energy efficiency, has the potential to significantly reduce a building's carbon footprint. The reduced refrigerant charge required by using R-32 provides further efficiency benefits and reduces installation and service costs.
