The Automatic Transfer Pump Set (ATPSF) is one of our best-selling products. Our customers love it for its reliability and rugged industrial construction. We consistently beat out our competitors because we build our products out of the highest-quality components. Behind each of our systems, you will find a team of engineers and technicians who are dedicated to getting you the best results possible. People. Products. Results.

Thanks to our new Flexible System Controller (FSC), we have added several exciting features to our  ATPS:

1. Redundant Communication

The FSC is masterless, and uses dual redundant, optically-isolated RS485 cables. RS485 cables eliminate hubs, switches, and repeater failure modes. Because both NodeNet cables communicate continuously, one cable can go down while the other continues communicating with no interruption. If any node fails, all the other nodes will continue to function.

As far as we are aware, Preferred Utilities is the only manufacturer offering this multiple failure backup system.

2. Faster Troubleshooting

Another feature of NodeNet communications is that it allows the operator to control or view any device, status, or alarm anywhere in the system from any touchscreen in the network. Because operators can see both digital and analog inputs and outputs from anywhere in the system, troubleshooting becomes streamlined, and much faster than it would be otherwise.

3. Distributed Controls

NodeNet communications provide the additional advantage of distributed control. The NodeNet system employs multiple distributed modular controllers, which are hard-wired to local devices. Even if both NodeNet cables are lost, local automatic control will continue. This modular aspect of NodeNet allows for maximum mission critical reliability.

4. Reduced Wiring Costs

The NodeNet communications network can reduce wiring cost significantly. The average number of wires per day tank (14 home runs) can be reduced to as little as 2 redundant communication cables in a loop between FSCs.
