Custom UL508A Control Panels for Water and Wastewater

Energenecs designs and builds a variety of control panels; including duplex lift station pump control panels, motor control centers (MCCs), and variable frequency drive (VFD) control panels. We have extensive experience providing panels with programmable logic controllers (PLCs) using radios, Ethernet, fiber and cellular, which are commonly used in the water and wastewater industry.

Many of the leading consulting engineers in Wisconsin are familiar with our premier panels, related control system expertise and technical services that we bring to their projects.

High Quality Components

All of the hardware Energenecs assembles & wires into our panels are superior quality components, such as Allen Bradley programmable controllers, Cutler-Hammer breakers and NEMA rated motor starters, Hoffman & Saginaw enclosures, both stainless steel and painted steel, whatever the project requires. Only quality relays, timers, power supplies, UPS systems, wire terminals are used. We design our UL508A custom control panels large enough so the wiring and components are easily accessible which allows for easier maintenance during the life of the panel.

Professionally Assembled UL508A Control Panels in Wisconsin

All of our Energenecs control panels are assembled in Wisconsin. We take UL very seriously, and it requires skilled shop personnel and electrical engineering knowledge to build everything in compliance with our professional UL certification. In addition, all of the internal panel wires are color coded in accordance to industry standards. Every one of our control panels includes complete custom wiring diagrams. As a control system integrator, our panels are “telemetry and SCADA ready”. Whether it’s a simple alarm dialer, or more complex radio, cellular, internet or fiber, Energenecs has done them all.

Custom Duplex Lift Station Pump Control Panel

Pictured is a very common duplex pump control panel for a lift station. The radio/antenna connected to the panel pump controller also talks to a SCADA system. Our stainless steel enclosures are provided with a stainless steel skirt which provides the NEC code electrical clearance coming out of a hazardous rated wet well, and also serves to aesthetically clean up the wire entries into the panel. Typically the left side of a duplex panel contains 120 volt circuitry, while on the right-hand side would have 230/480V motor control. We purposely separate 120v from the higher voltage for safety reasons. Primary automatic control of the two submersible pumps in the wet well uses an Endress Hauser submersible level transmitter, which is reliable and field-proven in hundreds of installations. Our backup floats give an operator peace of mind in case the level circuit, pump controller or a power supply were to fail. When the high float monitor activates, the backup pump control takes over and sends an alarm message to the operator.

Rockwell & Eaton Motor Control Center (MCC)

Energenecs takes responsibility for and commonly supplies Rockwell or Eaton MCC’s and variable frequency drives on numerous projects, along with our programmable logic controls. Knowledgeable electrical consulting engineers understand the serious design of the drive and MCC buckets and use our technical field expertise and CAD work to assist the design of these control circuits on their projects.

Redundant Custom PLC Panel

Pictured is one of many very sophisticated redundant Allen Bradley controllers installed in the Eau Claire, Wisconsin wastewater treatment facility. The PLC rack of modules on top left is a master and the rack to the right of it is a slave. The CPU modules in this class of controllers are synchronized such that if the primary fails, the other controller takes over. On a typical non-redundant panel, if the CPU fails, gets hit by a surge or has an anomaly and halts, everything monitored and controlled by the rack of modules is dead. It’s a serious event.
