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
