Baldor offers a complete line of motors designed for use in the harshest HVAC appliations. Both the Baldor chiller motor and Baldor cooling tower motor have integrated internal shaft grounding systems. Their cooling tower motors offer protection against environmental factors for added reliability. Baldor•Reliance® cooling tower motors offer a complete package in a totally enclosed design with additional sealing to minimize moisture entry points.
A recent study published by Dan Stelzner, chemical, oil and gas industry business manager for Baldor Electric Company, and Matti Paaso, states that the use of VFDs to adjust your pump's speed based on varying flow rates, will minimize wear of the pump's rods.
