Control Panels, Motor Controls & Instrumentation

To fill the void in process controls left by commercially available products, Metropolitan aggressively develops U.L. rated process controls to meet the needs of individual end-users. In most instances, by integrating our control systems with existing equipment, optimum system performance is achieved.

Our electrical designers take our experience and project specifications to create a solution for controlling your system. Communications, Monitoring, and Control are all commonly integrated into our systems.

Our custom control panel design and manufacturing capabilities include:

• U.L. listed manufacturing facility
• Relay logic
• Programmable logic controllers
• Control schemes: Pressure, level, smart, flow sensing, current sensing, etc.
• Enclosures: Available in all types of materials, mounting configurations and NEMA ratings.
• Power distribution equipment: Motor control centers, distribution panels, transfer switch

Our control panels are compatible with SCADA, including MetroCloud, our own cloud based SCADA system.

• Applications: Water distribution and wastewater collection.
• System design: Master controller, RTU, operation interface, hardware and software development.
• System integration: Existing sites, new sites, monitoring, monitoring and control.
• Communication: Leased lines, cellular, radi, hardwire, fiber optic, military grade IPSEC VPN connections (Virtual Private Networks)

Our team of in-house control experts also construct back-up power systems.

• Engine driven electric plants: Diesel, natural gas, with or without sound-attenuation.
• Battery backup- power source: Sumpro Auxillary Power (single-phase), DST50 Duplex Controller with back-up power (3-phase)
• Battery-operated pumps: Complete line of pumps and inverter packages.

Our motor control offerings include various motor options, switchboards, power distribution equipment and medium voltage motor control solutions for major water and wastewater facilities.

We can assist in the design and supply of Motor Control Products such as switchgear including MCCs up to 3000 amp, switchgear and distribution panels and variable frequency drives from single phase small systems and up to medium voltage (2300 volt) three phase gear for major water & wastewater facilities. Motor control centers have become the standard for motor power distribution, but alternative options can be utilized to best fit the needs of customers. Options such as stand-alone switchboards and distribution panels can be supplied to accommodate specific project requirements.

Control system choices designed to start and stop pump motors are typically limited to constant and variable speed drive systems. While constant speed systems are characteristic in the many industries we serve, variable speed systems incorporating variable frequency drives and reduced voltage starts have amassed a great deal of popularity in recent years due to their association with energy savings.

At the heart of every pumping system, you’ll find the control equipment. Whether a simple combination of relays, or a sophisticated PLC, this is where the system parameters are defined, qualified and processed. For this reason, it is imperative that the components are properly protected from the elements of the environment to insure safe and reliable operation of the entire system. Without good protection, it is only a matter of time before the system will fail. From the pristine atmosphere of a research and development lab to the harsh surroundings of a given job site, Metropolitan offers an enclosure for every application.

Our in-house manufacturing and fabrication capabilities allow us to provide custom enclosures of all types and varieties for our pump control systems. From custom designed and constructed housed control systems to customized traffic boxes, Metropolitan can provide an enclosure option that provides the necessary environmental protections while also providing ease of access.

The “traffic box” is a unique offering introduced by Metropolitan. Designed as an outer enclosure for more sophisticated systems, these units offer a protected environment for the control panel, transfer switch, telemetry and other important equipment. Not only does it provide protection against the weather and vandalism, it provides a much more aesthetically pleasing appearance than traditional “uni-strut” mounted systems. Available with stainless steel construction which offers improved protection and an impressive, maintenance free finish.

For the ultimate in control system protection, precast concrete buildings not only protect your control equipment, they can be sized to house standby generators, water pressure booster systems, lift stations, chemical feed equipment and mechanical systems. Metropolitan can design and build complete housed systems in a variety of finishes, colors and styles, while offering a cost-effective solution to standard “brick and block” construction. Precast buildings can be manufactured complete and the factory or field-erected, depending on project specifications. Our housed systems can also be equipped with added heat or air conditioning to provide a temperature controlled environment for added life of the most valuable equipment.

Metropolitan ‘s control system manufacturing includes explosion proof control panels and electrical control stations for plumbing or mechanical applications that are deemed hazardous. Such applications include areas with concentrations of flammable gases, vapors, liquids or combustible particles. The added use of heavy duty aluminum in our explosion proof control panel enclosures prevent explosive fumes from entering while also ensuring that any internal explosion does not ignite such exterior vapors.

Metropolitan offers a variety of integrated control instruments to ensure that system are continuing to provide sustained performance for their intended application.
