Daikin offers complete range of R290 heat pumps
2nd March 2026
BELGIUM: Daikin Europe has now launched a complete range of modular and monobloc air-to-water R290 heat pumps, covering capacities from 17kW to 2,000kW.
The EWA(Y)K-CZ monobloc units of 17kW-85kW are available in heat pump and cooling-only versions. The EWYK-QZ modular heat pumps are scalable up to 2,000kW.
The EWYK-QZ is available for orders from 1 April, while the EWA(Y)K-CZ will be available from mid-May.
With the use of propane, Daikin has paid specific attention to safety aspects with its Daikin Safety Shield. A key requirement is an independent 230V power supply for all safety devices, provided by the customer, to ensure proper operation under all conditions – even in emergency situations or in the event of a failure of the unit’s main power supply. This ensures continuous monitoring and activation of the safety systems. If the power supply to the safety devices is not active, is interrupted, or is not correctly connected, the unit will not start and will remain in a safe standby condition.
The electrical switchbox is designed as a controlled environment. It is continuously pressurised and equipped with refrigerant leak detection systems, supported by ATEX-certified ventilation, visual and acoustic alarms that provide immediate indication in the event of any abnormal condition.
The R290 refrigerant is factory-charged into dedicated storage tanks, increasing safety during transport and handling prior to installation. The refrigerant circuit also includes mechanical safety valves to manage potential overpressure conditions, with controlled discharge to the outside if required.
Additional safety measures allow any potential refrigerant dispersion to be detected and managed in a controlled manner, enabling the unit to shut down safely. The hydronic circuit is also protected: if a leak is detected, a shut-off valve isolates the water circuit, preventing refrigerant from spreading beyond the unit.
Daikin’s EWA(Y)K-CZ heat pump version can deliver leaving water temperatures of up to 75°C thanks to vapour injection technology, making it suitable for new installations as well as boiler replacement projects, even without changing the existing heat emitters. The cooling-only version ensures a wide operating envelope with a minimum chilled water temperature down to -15°C. The units operate within an outdoor air temperature range from -20°C to +46°C.
The units feature Daikin‑designed inverter‑driven scroll compressors and inverter‑equipped fans, both developed in‑house.
For larger capacity applications, the EWYK-QZ range adopts a modular architecture enabling multi-array configurations up to 2,000 kW working as a single integrated system.
The units are equipped as standard with inverter driven scroll compressors and EC brushless fans. Continuous modulation reduces on/off cycling, contributing to improved seasonal efficiency and enhanced operational stability throughout all year round.
For complex installations, the control concept operates on two levels. Within a single array, a multiple unit sequencer coordinates and regulates all base modules. Multi-array configurations are supervised by the Daikin Intelligent Chiller Manager (iCM) optimising load distribution among units, managing sequencing efficiently and supporting continuity of service in high-capacity installations.
Given the use of R290 refrigerant, Daikin is limiting the installation of the units to qualified and authorised personnel. Commissioning activities must be registered via Daikin’s proprietary e-Care application. This will ensure traceability of start-up operations and guarantee that the system is installed and operated in line with the original design intent from trained technicians.
