YMC 2 Water-cooled magnetic centrifugal chiller Cooling capacities from 800 kW to 3600 kW At Eurovent Standard Conditions this equipment meets A Class energy efficiency levels. Compatible range Features Our most advanced water-cooled chiller offers the following benefits: Enhanced efficiency Achieved through application of active magnetic bearing technology with variable speed drive. Superior reliability Use of active magnetic bearing technology removes friction and the need for oil resulting in a quieter and more reliable chiller. Enhanced sustainability Achieved by leak free refrigerant design, lower refrigerant charge and falling film evaporator. Low sound levels Advanced technology results in sound levels as low as 75dBA. A falling-film evaporator is more efficient because refrigerant is sprayed over the tubes, offering improved heat transfer and reducing refrigerant charge by 30%. To eliminate mechanical-contact losses in the driveline, the YMC2 chiller utilises a permanent-magnet motor and active magnetic-bearing technology. 64
