Water-cooled chillers  from the AQUARIUS G series are the perfect solution when maximum performance and absolute reliability are required. Their concept meets market requirements for versatility and high energy efficiency.

The stepless output control, electronic expansion valves and high-efficiency heat exchangers with integrated heat recovery help to achieve the highest level of output and very high seasonal efficiencies; both in the partial load range and under full load.

 

Thanks to  highly efficient screw compressors with stepless control  (Smart Stepless), the Aquarius chillers are particularly energy-efficient, especially in the partial load range. Partial or total heat recovery is available as an option.

 

Cooling capacities and efficiency values

For industrial production  =>  SEPR-HT  up to  9.07

Nominal cooling capacity 456 – 1934 kW

In air conditioning cold water systems  =>  SEER  up to  7.8

Nominal cooling capacity 351 – 1499 kW

 

"Water-cooled chillers of the AQUARIUS G series meet the seasonal efficiency standards of the ERP directive (TIER 2) and work with the environmentally friendly refrigerant R513A. On request, the refrigerant R1234ze is optionally available in a special design."
