Features & Benefits
FEATURES | BENEFITS |
Free Cooling | Up to 40% more economical when free cooling is applied |
Reliable and cost-efficient | With excellent efficiency of up to 92%, EC fans noticeably lower energy consumption and the running and lifecycle costs of precision air conditions and chillers |
Cost-efficient in partial load mode | The design of chillers assumes maximum heat load – but during normal operation, this capacity is seldom used 100%; with speed-controlled components such as fans or compressors, a great deal of energy can be saved in partial load mode |
