11 to 264 ton Air-Cooled Condensers feature increased energy efficiency and reduced sound levels sought after by the supermarket and grocery industry. Traditional condensers using 1140 RPM motors offer increased capacities, but cannot meet the low sound and high energy efficiency standards in demand today . These units are a great fit for many applications due to the combination of increased operating capacities, low sound levels and high energy efficiency. Choosing a model with the patented QuietEdge™ fan blade or variable speed EC motor makes this product more energy efficient while increasing cost savings.
