Air cooled water chillers_CYGNUS_4.1-67KW

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.
