YMC 2

Water-cooled magnetic centrifugal chiller

Cooling capacities from 800 kW to 3500 kW
R513A
“ Tailor and tune ” customized units around job specific design .
Features
Enhanced efficiency Achieved through application of active magnetic bearing technology with variable speed drive .
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 .
Superior reliability Use of active magnetic bearing technology removes friction and the need for oil resulting in a quieter and more reliable chiller .
Superior reliability Between the centrifugal technologies , this series has the smallest dimensions , fitting where others simply cannot .

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 YMC 2 chiller utilises a permanentmagnet motor and active magnetic-bearing technology .
