With enhanced HVAC-specific features and custom programmability, each drive provides simple out-of-the-box operation.

VLT® HVAC drives offer a range of pump-friendly features and options such as sensorless pump control, inherently NEMA 3R/4/4X enclosure types, and single phase –specific rated products making it the ‘drive of choice’ in the North American HVAC pump market. Some user friendly features that simplify operation and lower costs include an award winning LCP keypad design that reduces commissioning time and startup costs, and a watertight USB connection allowing for setup and programming with the drive enclosure sealed.
