The Daikin EWYK-QZ is a highly versatile and scalable air-to-water inverter heat pump system designed for demanding commercial and industrial applications. Its modular nature allows for expansion from a single 135 kW module up to an impressive 2000 kW, making it suitable for both new builds and extensive retrofits. The system utilizes R-290 (propane) refrigerant, a natural refrigerant with a Global Warming Potential (GWP) of just 0.02, ensuring compliance with environmental regulations and a significantly reduced carbon footprint. Engineered for peak performance, the EWYK-QZ features Full Inverter Technology with VFD scroll compressors and inverter-driven EC fans that dynamically adjust to load variations, optimizing part-load efficiency throughout the year. It can deliver heated water up to 75 °C, even in extremely low outdoor temperatures of -20 °C, positioning it as a direct and efficient boiler replacement. The "Plug & Play" design simplifies installation, with modules that can be added side-by-side, and options for pre-assembled manifold kits to minimize on-site work. Enhanced safety features, including dual refrigerant leak detectors, ATEX-certified extraction fans, and a comprehensive Daikin Safety Shield, ensure operational security. The system is managed by the Intelligent Chiller Manager (iCM) for full plant optimization, extended architecture control, and reduced operating costs.
