Cooling units

Closed cold water circuit without cooling compressor - 300 kWTT-300'000

Ideal addition to the extension of a refrigeration plant

Summary

  • Temperature range +10°C bis +15°C
  • Medium water
  • Cooling capacity 300 kW nominal
  • Internal circuit approx. 600 l/min

Working principle

  • The unit is equipped with two stainless steel heat exchangers
    placed laterally
  • Four high-performance fans on the top of the unit generate
    an air flow through the heat exchangers
  • The cold ambient air circulates through the heat exchangers and detract heat out of the process water
  • The air is blown out on top of the unit by the fans
  • A suction tank is installed before the pump it guarantees a problem free working of the unit and prevents the pump from dry run

Advantages of a closed cooling tower

  • On contrary to an open cooling tower there is no cooling
    water consumption
  • The close system also prevents the cooling water circuit
    from being soiled
  • The water temperature depends on the ambient air temperature
  • Therefore the reachable temperature of the circulating water is  approx. 10°C – 15°C higher than the air temperature

Particularities

  • The heat exchangers and die pipe work are completely manufctured from stainless steel
  • Separate control panel for inside use
  • The max. air temperature until the dry cooling tower should run is adjustable on the upper controlling instrument
