Saving energy at koloa landing
Koloa Landing Resort in Kauai utilizes Eco-Flow-C® Aquatic Variable Frequency Drives to drastically reduce energy costs.
September 1st, 2017 – H2flow Controls, Inc. (SYLVANIA, OH). Electricity costs throughout the continental United States typically range from six to 20 cents per kilowatt hour (kWh). In Hawaii, however, electricity costs are almost 50 cents per kWh!
Keeping those figures in mind, a 10HP recirculation pump that operates 24/7/365 (8,760 hours) at a 100% fixed speed would consume approximately 65,000 kWh’s. In the continental United States, the annual operating cost for such a pump would be somewhere between $3,900 and $13,000, depending on electricity costs. In Hawaii, at an astronomical .49 cents per kWh, the cost to operate the same pump would be approximately $31,850 per year. Paradise does have its price!
At the Koloa Landing Resort, located on the island of Kauai, the recent completion of a massive new condominium development in Spring 2017 included 17 new pumps for filtration and various water features. The completion of this project presented several new challenges, not least of which being the astronomical electrical costs associated with operating the new pumps.
H2flow Eco-Flow-C® Aquatic Variable Frequency Drives were introduced as a solution, and their installation has resulted in tremendous energy savings. Koloa Landing Resort is now saving in excess of $100,000 per year by using Eco-Flow-C®! It was determined that 10% speed reduction would equal a 29% energy saving for the resort, whereas a 20% speed reduction would almost cut the electrical energy consumption in half.
Additional benefits of Eco-Flow-C® include the unique Aquatic Controller user-interface, and the product’s NEMA 12 construction. The Aquatic Controller allows for easy setup of what can otherwise be a complicated process. Koloa Landing Resort also had some initial concerns that the hot, humid, and salty air on the island of Kauai could cause corrosion with the VFD. However, Eco-Flow-C® addresses these concerns with its rugged NEMA 12 construction, which is designed to withstand the harsh environment of a pool equipment room and the humid, salty air of Kauai.
