vlt® aqua drive - tlp equipment

For applications such as lift stations, farming fields or any location where three-phase power is not available, UL-listed phase-converting VLT AQUA Drives can control three-phase motors using single-phase 240V or 480V service. Since three-phase motors are more readily available and less expensive, a variable frequency drive can be a cost-effective solution in these applications while providing an attractive alternative to conventional phase conversion devices. In addition, a drive provides numerous other benefits not available with traditional phase conversion units, including speed control, motor protection and energy savings.

Danfoss’ unsurpassed experience in advanced variable frequency drive technologies makes the VLT AQUA Drive the perfect choice for all water and wastewater applications. The first drive designed specifically for water and wastewater applications, the VLT AQUA Drive offers the most advanced technology and features available in the market.
