NEMA Premium® Efficient Motors Standard

All Delta’s Cooling Towers will feature NEMA Premium® Efficient motors standard.  Premium efficient motors can dramatically reduce energy costs, increase productivity, and conserve energy.  NEMA (National Electrical Manufacturers Association) in 2003 developed these NEMA Premium® efficiency specifications to identify the most efficient motors available.  While forward thinking customers have already been requesting Premium efficiency, Delta is taking the initiative to be the 1st cooling tower manufacturer to standardize on NEMA Premium® Efficiency. These severe cooling tower duty motors will be backed by 3-5 Year warranties, reduce downtime and will be even more reliable than previous offerings.   Delta’s cooling towers have already been the choice for long-term reliability with the 15-Year warranty on the casing, seamless molded basins, and direct-drive no-maintenance fan assemblies. The NEMA Premium® efficient motors are suitable for VFD packages for further energy savings.  The Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ credits for both energy efficiency and materials selection may also be available. All shipments after May 1, 2007 will have NEMA Premium® efficient motors.
