What specific products were used in the Horlick control panels?

Panels included PLCs, OITs, remote I/O modules, VFDs, motor starters, with NEMA 4X stainless steel enclosures, air conditioners, power supplies, and Ethernet communication modules for skid-to-control room integration.

How were the panels protected for outdoor oilfield use?

Horlick used NEMA 4X stainless steel enclosures with integrated air conditioners to protect components from harsh weather, corrosion, and high temperatures on mobile skids.

What was the division of responsibilities between Horlick and the customer?

Horlick developed schematics, layouts, BOMs, built panels, and performed functional testing; the customer provided PLC programming and OIT screen development.

Mobile Wastewater Treatment Control Panels for Oilfield Water Recovery

Horlick manufactured custom industrial control panels for a worldwide water management solutions provider's mobile wastewater treatment facilities. These systems treat oil and gas well wastewater to recover fresh water for reuse in oilfield operations using proprietary low-temperature desalination processes. Equipment skids from multiple vendors were integrated with Horlick's NEMA 4X stainless steel panels, including a main control room panel and remote skid panels communicating over Ethernet. The project supported multiple recycle plants and smart evaporation systems.

The Challenge

The customer needed rugged control solutions for outdoor mobile water treatment skids in harsh environments exposed to weather and contaminants. Integration of equipment from multiple vendors required reliable Ethernet communication between remote panels and a central control room. Panels had to house PLC remote I/O, motor starters, and VFDs while maintaining cooling in NEMA 4X enclosures. Ensuring functional testing before shipment was critical for operational reliability in oilfield settings.

Our Solution

Horlick designed and built main control panels with PLC and operator interface terminal (OIT) for system-wide monitoring and control in the control room. Remote panels on each equipment skid included PLC remote I/O modules, motor starters, and variable frequency drives (VFDs) for individual skid control. All panels used NEMA 4X stainless steel enclosures with air conditioners for harsh outdoor protection and Ethernet for communication. Horlick provided electrical schematics, layouts, bills of material, and pre-shipment functional testing, while the customer handled PLC programming and OIT screens. Power supplies and communication modules supported the networked setup.
