Emotron FDU regulates flow and pressure by continuously adapting motor speed. Therer is no wasted energy and no unnecessary wear on equipment. A sleep function further reduces energy consumption by pausing the motor when it is not. An automatic pump rinsing function also increases efficiency. Multiple pump or compressor control is a reliable and cost-efficient method of keeping a constant flow or pressure despite varying demands. Emotron FDU controls up to seven drives. Emotron FDU is available in IP20/21and IP54 versions. The robust steel construction in IP54 version allows you to install your AC drive close to the application, which saves the cost of cabinets and long motor cables. The 300-1,500 A units (IP20 modules) are also available in compact CG-designed IP54 cabinets.IP20/21 series 25-244 A are optimised for mounting in control cabinets (IP20) or on electrical room walls (IP21). Emotron FDU has a robust and compact design, with easy access to power terminals and an extended temperature range up to 55 °C.

Emotron frequency inverter FDU 2.o series has full control and reliable operation
Emotron FDU 2.0 variable speed drives offer reliable, cost-efficient and user-friendly operation of your pumps, fans, compressors and blowers. Full control of flow and pressure ensures an optimized operation, with reduced energy consumption and less downtime. The Emotron FDU also protects your equipment from damage and unnecessary wear. With all its functions included in a compact IP54 enclosure, the Emotron FDU is costefficiently installed close to the application. An intuitive user and process interface makes it easy to communicate critical parameters to other parts of your process. Fit-for-purpose is the key term for Emotron FDU.
Protective starts and stops
Emotron FDU variable speed drives offer soft starts and stops that protect your equipment. Reduced start currents result in smaller fuses, cables and energy bills. Controlled stops eliminate the risk of water hammer and other costly damage. In addition, you no longer need expensive motor-controlled valves to reduce pressure spikes. The result is reduced installation, energy and maintenance costs.
Controlled ramping for safe start-up
Emotron FDU offers a unique function that protects your equipment by ensuring a controlled ramping up of the DC link voltage. This so called HCB ramping (Half Controlled Bridge) offers a safe start-up, and detects phase failure and asymmetries. As there are no built-in resistors or bulky contactors, both size and maintenance are reduced. You can safely turn the variable speed drive on and off with an external contactor, as often as needed. In other drives this could cause breakdowns or serious damage.
Protection against damage and downtime
A built-in shaft power monitor and a unique load curve protection function protect your process against damage and downtime. The load curve of the controlled equipment is monitored across the entire speed range. Any over- or underload situation that could cause inefficiency or damage is detected immediately. You can easily set the warning and safety stop levels that allow you to take preventive action before damage occurs. There is no need to worry about dry-running, cavitation, overheating or blocked pipes. And you will be warned if, for example, your compressor is idling, a fan belt is broken or a valve has not fully opened. Emotron FDU protects the process and makes sure it works as efficiently as possible.
Emotron FDU has been developed to control flow and pressure, for example in pump systems. The complete range covers motors with output from 0.18 kW to 1,500 kW and mains voltage from 230 V to 690 V. The unique load curve protection detects any deviation from normal load across the entire speed range, and sends a warning or stops the process before any damage is done (patent EP 1772960).
Save energy and optimize operation with Emotron vfd FDU 2.0 series
Emotron FDU has been specially developed to regulate flow and pressure. Being able to continuously adapt the operation of your pumps and fans to match demand by controlling motor speed results in considerable energy and maintenance savings, compared to the use of throttling valves or dampers. The latter is like running a car at full throttle while controlling the speed using the brakes. Further energy savings, as well as reduced motor noise, are offered thanks to flux optimization. This function increases motor efficiency by adjusting the output voltage to the actual load, improving the motor’s actual power factor.
Sleep function optimizes operation
A built-in sleep function optimizes the process by lowering the motor speed to zero when it does not need to be run in order to keep up the required pressure. The motor is restarted when the need occurs again. This reduces energy consumption and equipment wear. You can also set the sleep mode to be activated in low flow or no flow situations that are not detected by the PID control, for example due to valves which are closing too slowly. This avoids the pump and motor overheating and energy being wasted.
Speed control offers considerable energy savings. In this pump application, energy consumption is reduced by up to 50% compared to throttling valves. Calculation is made using Emotron Energy Saving Calculator and assumes a 2.2 kW motor. Emotron FDU saves energy by pausing the motor whenever it does not need to be run in order to keep up the required pressure. The sleep mode can also be activated in low flow situations not detected by the PID control, thus avoiding overheating and energy waste.
Automatic pump rinsing increases efficiency
Emotron FDU can be set for automatic pump rinsing using a timer. When a pump is running at low speed or standing still, sludge often sticks to the impeller, reducing the pump’s efficiency. With an Emotron FDU variable speed drive you can set the pump to run at full speed for certain intervals or for a certain time at start-up, before returning to normal operation. This cleans the pump and pipes and increases efficiency.
Emotron FDU offers automatic pump rinsing. In this example a centrifugal pump at a sewage treatment plant is set to run at full speed for certain intervals to rinse out sludge, thereby increasing efficiency.
Multiple control for efficiency and reliability
Using multiple pumps or compressors to keep a constant flow or pressure despite varying demands is a flexible, reliable and cost-efficient method. At all times you only use the number of pumps or compressors needed and thus the amount of energy required. An Emotron FDU controls up to seven drives without PLCs or other external equipment. When, for example, one pump reaches its limit, or when the demand decreases, the Emotron FDU starts or stops more pumps. Which pumps to start or stop is decided by the variable speed drive, giving them all equal running time. Should one pump or motor break down, the system automatically switches over to the next in line, avoiding unnecessary downtime.
Multiple pump or compressor control is a reliable and cost-efficient method of keeping a constant flow/pressure despite varying demands. One Emotron FDU can control up to seven units in a master/slave solution, with, for example, Emotron MSF softstarters working as slaves.
