Avoiding failure due to load fluctuations
SIRIUS soft starters make it easier to start conveyor systems. Loads fluctuate when bulk solids are being conveyed or processed. These fluctuations might be caused by a change in the angle of the conveyor belt, which influences the parameters. If the parameters that you have selected for subsequent motor starts do no match the altered load, you can damage the machine or get an aborted start.

Clean wastewater pumps without fiber collection
SIRIUS soft starter reduces the maintenance effort when pumps get blocked. Impellers are frequently blocked by sanitary and other waste products that are not intended for removal in wastewater. Blockages of this kind can be a costly aspect of wastewater handling and have to be removed manually.
Stopping pumps without water hammer
Switching off pumps that convey large volumes of water is a particular challenge. The pump stops immediately, causing the water in the pipes to also stop immediately. The kinetic energy still in the water is transmitted as "water hammer" onto pipes, couplings, valves, and seals. This damage can be serious to the pipe system.
Reliable design for conveyor belt motors
Comprehensive condition and fault monitoring with SIRIUS soft starters. Conveyor systems are usually modernized to optimize operation and availability. If motors are monitored effectively, changes and imminent interruptions in the running operation can be detected early. However, this means that any additional diagnostic equipment must be integrated with the existing space already occupied by the plant. That's where a comprehensive condition and fault monitoring process comes into play. And we can help with SIRIUS soft starters.

SOFT STARTER SUCCESS IN TEXAS
"PERFECT FIT" FOR HOUSTON CUSTOMER
One of our account managers in Houston, Texas was asked about getting a 150 hp soft starter. The key was finding one that's under eight inches deep - allowing it to fit in a standard Motor control center (MCC) bucket... SIRIUS 3RW5 soft starters were a perfect fit! It was such a hit, the customer has decided to change out all 3 of the other units at the plant.
