Operation noise level (50/60Hz) (6) dB 62/67 59/63 69/71
  • 1 Operation when chilled water temp. is 20°C and cooling water temp. is 32°C. Cooling capacity is at least 95% of listed figures.
  • 2 Source voltage phase unbalance should be less than ±3%.
  • 3 The figure noted is when the equipment is operating at the highest capacity of its normal operating range.
  • 4 Stable load indicates continue operation with maximum load cluctuation of ± 10% of the current load.
  • 5 The capacity figures listed represent just one point on this model's flow-rate/head characteristic curve. Pumps differ between models; for model specific details, please refer to the pump characteristic curves.
  • 6 Operating noise levels are from a position of 1m in front of the unit and at a height of1m.
  • 7 Unit comes with a built-in multi-purpose overload and short circuit protetion breaker. Note 1: The chilled fluid can be either potable water or a low concentration ethylene glycol water solution of 10% or less. Note 2: Please install the included strainer (40 mesh) to the fluid intake port. Note 3: Heat output of the equipment (in kW) is about 1.3 times the colling capacity. (air cooled models only)
