The flow requirements for every commercial swimming pool are highly variable. It makes perfect sense for the commercial pool pump to be highly variable as well. Commercial pools around the world depend on EcoPro Variable Speed Drives and Pumps to conserve energy and lower costs. A fixed speed pump is not suitable for multiple processes or varying circumstances. A Variable Speeed Drive (VSD) equiped Commercial Pool Pump is much better suited for the complex and highly variable conditions found at commercial swimming pools.
Commercial pools are strictly regulated by government authorities to protect public health. Rules and regulations often require some or all of the following:
Savvy pool owners have discovered that the GPM may be reduced after the 6 hour turnover rule has been met. This opens up the door for huge savings. Commercial pool operators simply adjust the flow rate down for a large portion of the day which dramatically lowers electricity costs. And in some areas, electricity costs are lower during non-peak hours. Adjusting filtration schedules based on power costs allows for even more savings. Annual savings between $5,000. and $9,000. are common.
A variable speed drive is a device that is used to control the speed of an electric motor. EcoPro converts incoming AC power to DC and then back to quasi-sinusoidal AC power using advanced inverter switching circuits. With EcoPro Pumps, the speed is precisely controlled by changing the frequency of the electricity delivered to the motor.
The technology behind most swimming pool pumps hasn’t changed much in the last 50 years. But EcoPro Commercial Pool Pumps have changed that by using variable-speed technology. Commercial pools can now take full advantage of variable-speed drive technology. This type of commercial pool pump uses a special drive to control the speed (RPM) of the pump. By adjusting the speed to the optimal rate for a given requirement, a large amount of energy can be saved.
70 – 80% of a commercial pool’s electricity bill is normally due to inefficient pumps. Dramatic reductions in electricity costs can be made by installing an EcoPro Variable Speed Pool Pump. How much can be saved? It’s common for a 200,000 gallon commercial pool to reduce the kW usage by 60,000 kW per year. That’s typically $9,000. per year in electricity savings! Many governments are pushing the swimming pool industry to adopt this technology to reduce wasted electricity, and reduce the carbon footprint. Federal, state or local governments may offer tax rebates or loans to help with the costs of these smart upgrades.
EcoPro reduces energy cost and consumptions by an average of 60%. And since the cost of an EcoPro Pump is less than 35% more than a regular commercial pump, the return on investment (ROI) is typically only 10 – 18 months.
Soft-start and soft-stop are standard EcoPro. When a typical AC motor is started up, it takes as much as seven to eight times the motor full load current to start the motor. When the EcoPro drive starts the motor, it initially applies a low frequency and voltage to the motor. A low starting frequency avoids the high inrush current occurs when a motor is started by applying full voltage. After rotation begins, EcoPro increases the frequency and voltage at a controlled rate to accelerate the load without drawing excessive current.
This soft-start feature allows EcoPro to develop 150% of its rated torque while the VFD draws less than 50% of its rated current. The stopping of EcoPro is the opposite of starting. The frequency and voltage are decreased at a controlled rate. When the frequency nears 0, the motor stops. EcoPro’s advanced drive reduces wear and tear and extends the life of the motor.
In addition to big savings, EcoPro offers many more benefits you won’t find on other commercial pool pumps.
