Pump Frequency Drive for Closed cooling towers

Closed Cooling Towers

 

The nominal climatic conditions defined for the sizing of a cooling tower are met less than 15 days a year.

So, a marginal reduction of the evaporative circuit flow rate allows a major decrease of the electric consumption during 95 % of time.

This electric consumption reduction is optimal when the variation is combined with a variation on the fan speed.

Optimization of speeds maintaining the turbulent regime on the exchange surfaces preserves the cleanliness of the heat exchanger.

Solution :

The pump frequency drive on a closed cooling tower.

 

 Benefits : 

• 50 % of energy saving on the annual consumption of the pump
• Return on investment from 6 to 8 months
• Built in and pre-cabled option: Plug and Play with regulation adapted to the operating mode (economic criteria water or electricity)
• Long life cycle of the pump and reduction of the maintenance costs bound to the wear parts

 

Usefull :

• Speed ranges factory-pre-set
• Compact skid integrated into the room exchanger
• Possibility to adapt the variation to a specific requirement 
• Removable memory key reprogram according to the recorded model
