BENEFITS
• Extremely low noise levels;
• High EER/COP values and seasonal performance indices;
• Ideally suited to commercial and domestic chilled water
air-conditioning applications;
• Extended operating limits;
• Optimisation of heat pump defrosting cycles thanks to
the exclusive Frost Detecting System (FDS) (Minimum
ambient temperature in heat pump mode = -10 °C);
• Self-adaptive temperature control (SAC) for efficient
operation with installations having low water contents;
• Designed for installation in confined spaces;
• Easy to use thanks to a controller with icon-based dual
display;
• Easy installation and simple access to all chiller
components.
