Best performance and maximum reliability

The water cooled reversible water chiller AQUARIUS G is the best solution for large process cooling applications when reliability and high performances are the main requirements.

The AQUARIUS G units are designed to meet market requirements in terms of versatility and energy efficiency using high quality components. The smart stepless cooling capacity regulation, electronic expansion valves and high efficiency heat exchangers with integrated heat recovery systems allow to increase the partial and full loads efficiency optimising the seasonal performances.


  • Low GWP refrigerant R513A;
  • Seasonal energy efficiency compliant with ErP Directive 2009/125/EC;
  • High energy efficiency levels, especially at partial loads;
  • Smart stepless cooling capacity regulation with self-adaptive control;
  • High accuracy and adaptability in cooling capacity regulation;
  • Single compressors minimum capacity step 25%;
  • Heat exchangers with low water side pressure drops in order to reduce the pumping systems management costs;
  • Integrated heat recovery systems (partial or total heat recovery);
  • Condenser outlet water temperature up to 60 °C.
