Cooling Tower Parts
Some SPX Cooling Technologies products with low hp requirements include electronically commutated (EC) motors. Cooling towers that use high-efficiency EC motors usually have smaller capacity and footprint with a maximum application size of 10 hp or one-meter fan diameters.
SPX Cooling provides the EC motor as standard on the Marley® LW Fluid Cooler, Recold® LC Evaporative Condenser, Marley V Tech Adiabatic Fluid Cooler and Recold V Tech Adiabatic Cooling System.
Compared to belt drives and other low-horsepower motors (less than 5 hp), EC motors are consistently more efficient. In small-hp applications, the EC motor presents no power transmission loss while other low-hp motors and belt drives can experience power transmission losses from 5-20 percent.
Because EC motors use sealed bearings, there is virtually no maintenance. Serrated fan blades also result in the EC motor’s value as a low-sound power transmission technology. All EC motors include a five-year warranty.
