Technical Notes & Operating Conditions

• The cooling efficiency of the machine depends on the surrounding air conditions. The installation area needs to be well-ventilated to prevent the ambient temperature from exceeding 45°C. 45°C.
• Use only Genuine lubricants recommended by KOBELCO to ensure optimal durability and performance.
• With this version water cooling, needs to be maintained water temperature ≤ 35°C.
• Refer to standard technical guidelines on water quality when operating the cooling system.
• Specifications and design subject to change without prior notice.
• Contact the supplier to receive guaranteed performance value.
  (Fixed speed line using a starting system Star–Delta).

Measurement conditions and verification standards

• Standard suction conditions:
  Absolute suction pressure: 0.10 MPa
  Suction temperature: 20°C
