A new brochure on the VSM family of variable-speed motor controls describes applications in which they can be used, including air-handling units, fancoil units, and fan-powered VAV terminals. In addition, the brochure gives the cost savings and improved performance and manufacturing advantages for typical HVAC products using the VSM components. According to the company, the units are capable of matching output to demand, resulting in quieter, more efficient, more closely controlled, longer-lived air moving equipment.
