Control Panels

Horlick Industrial Control Panels Used to Control Water Treatment Systems

A US-based, worldwide water management solutions provider uses Horlick control panels to control its mobile wastewater treatment facilities.

The Horlick Company is a manufacturer of industrial control panels used in a wide variety of applications. One application involves the control of mobile water treatment facilities whereby the wastewater from an oil or gas well is treated to a level that allows it to be re-used in oilfield operations. Horlick’s customer provides an economic and efficient method for exploration and production companies to combat their water scarcity and disposal challenges.

Horlick’s customer uses patented technology to provide multiple services for its oilfield customers. One process uses proprietary low temperature, ambient pressure methods to recover fresh water from the desalination of industrial wastewater. The wastewater is used to humidify a carrier gas like air, nitrogen or helium. During the humidifying process, fresh water is separated from the dissolved impurities. The fresh water is subsequently recovered in a proprietary dehumidification process.

Industrial Control Panel for Water Treatment Systems

In order to construct their mobile water treatment platforms, the customer procures equipment skids from multiple vendors and they then tie them together to form a full treatment system. In some cases, there is a separate container that houses the control room for the entire operation. The Horlick control panels are placed on each of the equipment skids and in the control room and they communicate over Ethernet.

The Main Control Panel in the control room typically contains a programmable logic controller (PLC) and operator interface terminal (OIT) that are used to control and monitor the entire system.

The Remote Control Panels each have a unique design and they contain the PLC remote I/O, motor starters and variable frequency drives (VFDs) required for control of the individual equipment skids. Since the skids are located outdoors in harsh environments, Horlick utilizes NEMA 4X, stainless steel enclosures and air conditioners to protect the control components and keep them cool.

For these projects, Horlick develops the electrical schematics, control enclosure layouts and bills of material, while the customer provides the PLC programming and OIT screen development. A functional test of each control panel is performed prior to shipment.

The customer’s Vice-President of Engineering has been working with Horlick and Shawn Hennessey since 1999. He made the following comment: “Shawn’s excellence and dedication are the reason why I would not go anywhere else for control panels. I trust Shawn. I know I can rely on him to step up and do it right!

Horlick has recently completed six projects for this customer to include the control panels for three recycle plants and three smart evaporation systems. Additionally, the customer has just placed an additional order for twelve more control panels to be used in three new recycling plant projects.

Control Panel Manufacturing

Each Horlick industrial control panel is manufactured in our 12,000 square foot facility in Randolph, MA.


Our control panels are built in standard NEMA 1, 4, 4X or 12 enclosures. For hazardous locations, we also fabricate control panels in NEMA 7&9 explosion-proof enclosures. For large-scale process projects that utilize multiple motors, we offer our packages in a customized motor control center.

For applications that require something other than a standard sized enclosure, we can provide custom enclosures built to our client’s exact requirements. Additionally, if required, we can paint enclosures in custom colors using our paint spray booth.


We utilize both IEC and NEMA devices in our construction. Our standard packages may include but not be limited to any of the following devices: circuit breakers, motor-starters, electronic soft starters, variable frequency drives, servo controllers, programmable logic controllers (PLCs), human machine interfaces (HMIs), intrinsically safe relays and barriers, and door-operated pilot devices.


Our control panel shop is UL508A and UL698A listed and we have the ability to design, build and comply with the European directives required for CE marking. Completed control panels are tested and inspected to insure that they comply with the National Electric Code NFPA 70.

    Connecting and controlling multiple, remote industrial control panels through fiber optic cable.

    A soil remediation project requiring 10 remote recovery wells will be controlled via separate control panels using fiber optic cable.

    The Horlick Company is a manufacturer of industrial controls used in a wide variety of applications. A single control panel is commonly used to control an individual piece of equipment or it can be used to control a localized process that may consist of pumps, blowers, heaters, etc. For larger projects, or projects where the equipment is separated by a great distance, several control panels may be needed to integrate the process. These control panels are typically networked together and controlled from a central location.

    This application note describes a groundwater remediation installation in South Carolina that required control panels to be installed at (10) separate recovery wells to be remotely controlled and monitored by an eleventh ‘main’ control panel at a central location.

    Remote Control Panel for water remediation project

    Remote Control Panel

    Due to the distances involved and client preference, there were three options to facilitate communication between the eleven control panels:

    1. Direct wire
    2. Fiber Optic Cable
    3. Leased Cellular Network

    The project specification allowed for a single programmable logic controller (PLC) within the main control panel, combined with distributed inputs and outputs (I/O) to be located in the individual well control panels. The original design specification showed preference for a leased cellular wireless network to be used as the means of communicating between the control panels. The importance of maintaining a reliable and robust connection between the control panels, combined with the fact that the furthest well control panel was located 4,000 feet away from the main control panel, led the Horlick Company to propose a fiber optic network for the communication platform. Since the client already had to trench for the water piping, Horlick felt that the cost impact of adding the fiber optic cable runs to each well would not be as significant had the trenching not already been required. Additionally, once installed, there would be no further cost for the fiber optic cable solution. If the client had chosen the cellular approach, initial equipment costs would have been compounded by monthly network maintenance fees during the lifetime of the project. Additionally, there was also the uncertainty of required cellular equipment replacement in the event of carrier technology upgrades.

    The client ultimately agreed with Horlick’s approach and Horlick provided a main control panel with an Allen-Bradley Compact Logix PLC and (10) remote well control panels with Allen-Bradley distributed I/O. Each well control panel contains motor controls for the groundwater pumps. The level and flow rate from each well are monitored and the flow is controlled through the operation of a modulating control valve associated with each well. The parameters, set points and operation of each recovery well are controlled from the main control panel. All of this data is communicated over the fiber network. The fiber optic cable is terminated on N-Tron FX series Ethernet switches that are utilized to complete the network. To date, the system has been running without incident and the client can take comfort in the fact that neither the weather, cellular tower uptime, nor radio interference will have any impact on the effectiveness of their system.

    Main Control Panel

    Remediation Project Details

    The Horlick Company, Inc. supplied the control panels to Mid-Atlantic Environmental Equipment, Inc. (MAE2). The control system has been designed and manufactured to operate groundwater recovery and treatment equipment associated with extraction of a large volatile organic compound (VOC) plume in the aquifer.

    The end customer, a valve manufacturer in South Carolina for over 40 years, has allowed solvents to contaminate the soil around the factory. Since the solvents are water soluble, the solvents have leached into the local aquifer and have contaminated the water table in a nearby residential community. With all of the wells in operation, the system has the capacity to run at 275 gallons per minute while it draws down the water and allows the contaminants to be removed.

    MAE2’s system included (10) groundwater pumps, combined with equalization and storage tank transfer pumps, and dual air stripper blowers that are all controlled by the Horlick control system. This is a project that was in discussion and preparation for 8 years. The site startup occurred in September of 2016 and the cleanup is expected to last for about 20 years before remediation is complete.

    “Horlick control panels are laid out well and use quality materials” said Shawn Evans, Vice President for MAE2 “Horlick has a remarkable range of products and capability; they can provide control panels that are single use basic panels all the way up to entire systems. We never use anyone else for our control panels as Horlick provides a very good product at a fair price”
