  • 1. Operating conditions: Chilled water temp.:20 °C, Cooling water temp.:32°C(water cooled units only), Ambient temp.: 32°C. Cooling capacity is atleast 95% of listed figures.
  • 2. Source voltage phase unbalance should be less than ±3%.
  • 3. The figure noted is when operating at the highest capacuty in the normal operating range.
  • 4. Continuous current load fluctuation with ±10%, and with stable ambient temp. and power supply, etc. Does not include starting times or when the cooling load is too small, in which case the compressor may cycle on and off.
  • 5. Operating nolse levels are from a position of 1m in front of the unit and at a height of 1m.
  • 6. Unit comes with a built-in multi-purpose overload and short circuit protection breaker.
  • 7. Use antifreeze when operating with fluid temperature settings of 0 to 3°C. (8), At time of startup only. Will differ depending on ambient temperature.
  • Note 1: The recommended liquid (chilled water) that can be used is either clean water or a 30 tp 40% ethylene glycol solution. Note that there will be a 10% reduction in cooling capacity if using a 30 to 40% ethylene glycol solution. Alternatively, if deionized water is to be used , it should have an electrical conductivity of at least 1 µS / cm.
  • Note 2: Heat output from the unit (in KW) is approx. 1.3times that of the cooling capacity.(Air cooled models)
