Supporting South Carolina’s Plastic Manufacturing Industry with HVAC Expertise

From the moment your day begins, plastic products are an essential part of your routine—from brushing your teeth with a plastic toothbrush, pouring milk from a plastic container, or using a plastic pen to jot down your to-do list. With plastic woven into our daily lives, manufacturers across South Carolina are working around the clock to meet demand, producing everything from automotive parts to plastic pellets and packaging materials.

W.B. Guimarin: A Trusted Partner for Industrial Manufacturing

At W.B. Guimarin, our Engineering and Service Teams specialize in supporting plastic manufacturers with HVAC and mechanical system solutions tailored to their production needs. Recently, Neal Ludwig and his team assisted a Greenville-based plastics manufacturer facing a serious production challenge—alarm systems triggering shutdowns and discussions of replacing multiple compressors on their aging McQuay chillers.

Fortunately, before making costly replacements, the manufacturer turned to our Service Team for a second opinion.

Expert Diagnostics Save Costly Equipment Replacements

While modern chillers feature sophisticated monitoring systems, troubleshooting still requires seasoned expertise. After a thorough diagnostic evaluation, we determined that:

• All four compressors were fully functional—no replacement was necessary.
• The real issue stemmed from incorrect electrical wiring, which caused low evaporator pressure alarms.
• A miswired control system was unnecessarily activating both first- and second-stage cooling, instead of just the first stage as required.

By correcting the wiring, we eliminated the issue and restored full operational efficiency, saving the manufacturer from an unnecessary equipment overhaul and potential production losses.

Custom HVAC Solutions for Plastics Manufacturing

Each plastic production facility—whether involved in extrusion, injection molding, thermoforming, or blow molding—has unique mechanical and HVAC requirements. Process cooling, dehumidification, and air quality control are all critical to maintaining product consistency and equipment efficiency.

Rather than listing every plastic manufacturer in South Carolina, we want to hear from you—what challenges is your facility facing? Let W.B. Guimarin provide the expertise, customized solutions, and reliable service needed to keep your production running smoothly. Contact us today to discuss how our team can support your operations.
