Emotron FlowDrive is designed for use in the most common pumping scenarios (1-2 pumps of any brand) in the wastewater management industry. The heart of FlowDrive is automatic reservoir level control — which optimises energy use, minimises the need for maintenance and enables real time process monitoring.

Key Features :

• Energy savings, thanks to automatic optimal pump speed control
• Built-in functions that minimise maintenance needs
• Absence of a PLC/pump controller reduces cost and effort involved in programming
• Having one less component reduces complexity and increases reliability
• Less starts and stops of the pumps thanks to longer run times caused by lower average frequency
• Full connectivity to suit different user scenarios
• Access to system data/parameters for continuous performance monitoring.

The EMX-R drive system consists of a motor and a corresponding electronic controller. Uniquely, EMX-R is equipped with an integrated electronic rotation sensor, RotoSensTM, which eliminates the need for a mechanical sensor. It can also easily handle a conventional mechanical rotation sensor. The EMX-R drive systems are based on the switched reluctance (SR) motor technology. The SR technology allows the EMX-R motor to drive heat exchanger wheels with diameters up to 3.5 m without any need fora gearbox.

Key Features :

• Purging operation
• Motor protection
• Active holding torque
• Soft starting/stopping
• Rotation sensor, integrated electronics
• Shod circuit protection
• Selectable maximum speed
• Robust motor without gear or fan
• High efficiency - No gearbox losses
• Integrated motor cable
• Holding torque - prevents involuntary heat transference
