Introducing Innovative New Features in Drives – Danfoss VLT Aqua Drive

Most modern drives have features incorporated as standard that can provide huge benefits to the user. In this new monthly feature from Quantum Controls, the UK’s leading independent supplier of Drives Services, we introduce to you the very best features from all major manufacturers.

The VLT® AQUA Drive is designed to provide the highest level of performance of AC-motor-driven water and wastewater applications, suitable for all types of pumps. Featuring a wide range of powerful standard features, which can be expanded with performance improving options, the drive is equally suited to both new and retrofit projects.

The unique back-channel cooling concept transfers 90% of heat away from the room, resulting in high energy savings relating to additional air conditioning. Back channel cooling is possible in drives 11kW and up.

With the drives’ control algorithms and design, energy efficiency is maximised. The VLT® AQUA Drive can realistically offer first-year cost savings of between 10–30% compared to traditional drive solutions.

Unique dedicated water and pump features such as burst pipe monitoring, dry-running protection and flow compensation secure and empower your pumping application independent of the motor technology.

Flow Compensation – A pressure sensor mounted close to the pump provides a reference point that enables pressure to be kept constant at the discharge end of the system. The drive constantly adjusts the pressure reference to follow the system curve. This method both saves energy and reduces installation costs.

The Pump Cascade Controller distributes operation hours evenly across all pumps. Wear and tear on individual pumps is therefore reduced to a minimum, extending their lifetime expectancy and reliability considerably.
