If your cooling tower is a constant concern because maintenance needs vary widely depending on the season and the installation uses too much energy here is a solution that will improve yield and reduce costs.

Cooling Towers are used across a wide range of industrial and commercial applications and installing inverter drives to control the fan and pump speeds offer money/energy saving the opportunities.  Assuming over a given season, the fan and pump motors must operate at full speed just 2% to 5% of the time—the rest of the time this energy is wasted.

This solution uses up to 50% less energy than direct-start fans and pumps and eases maintenance.

The best way to control air-water exchange in a cooling tower is to use variable speed drives to control the tower’s fan and pump, eliminating additional maintenance-hungry mechanical systems while meeting the tower’s needs. A programmable controller (PLC) regulates fan airflow and pump volume via the variable speed drives.

Benefits for the user

– Reduce energy consumption

– Improved yield by regulating water temperature

– Lower maintenance requirements, especially in extreme weather

– Quieter operation

– Low harmonics: THDI < 30%

– Eliminates inrush current due to motor start-up

– Simpler mechanics (no brakes, sensors, or rotation inverters)

– Extends lifetime of mechanical components

– Facilitates maintenance planning

Why use Altivar ATV21 variable speed drive from Schneider Electric?

The Altivar 212 drive is a frequency inverter for 0.75 kW to 75 kW three-phase asynchronous motors.  It has been designed for the most common fluid management Heating, Ventilation and Air Conditioning (HVAC) applications in buildings the service sector.

Its design is based on eco-energy with a reduction in energy consumption of up to 70% compared to a conventional control system. The Altivar 212 is operational from the moment the power is turned on and it can be integrated into a building energy management system to achieve maximum energy efficiency.
