⭐ Customer Reviews and Testimonials

Authentic User Feedback

🏭 Industrial Manufacturing User Reviews

⭐⭐⭐⭐⭐ James Peterson - Automation Engineer, Automotive Plant
"We integrated the Coolmay EXGG-50KH into our assembly line temperature monitoring system last April, and it’s been rock-solid. The 5-inch HMI touchscreen is incredibly responsive, and the Pt100 sensor integration delivers consistent readings within ±0.4°C. No more guesswork in our curing process. The CE certification gave us peace of mind during our safety audit."

🌡️ HVAC System Integrator Reviews

⭐⭐⭐⭐⭐ Linda Wu - Controls Specialist, Commercial Facilities Group
"Deployed two units across a hospital HVAC retrofit project. The multi-protocol connectivity was a game-changer—connecting legacy BMS via RS-485 while feeding real-time data to our cloud SCADA over Ethernet. Setup was smooth thanks to the intuitive interface. After six months of 24/7 operation, zero failures. The IP54 rating handled dusty mechanical rooms like a champ."

🍲 Food Processing Plant User Reviews

⭐⭐⭐⭐☆ Carlos Mendez - Plant Operations Manager
"Using the Advanced Model for oven temperature control in our bakery line. The dual Ethernet ports allow redundant network paths, which reduced downtime during switchovers. We did have a minor firmware hiccup early on, but Coolmay’s support team provided a custom update within 48 hours. Now running flawlessly. Wish the base model had WiFi, but the Pro would’ve been overkill for our needs."

Purchase Date: November 2024 | Usage Period: 7 months

🧪 Chemical Processing Pilot Project Review

⭐⭐⭐⭐⭐ Dr. Elena Vasquez - Process Automation Lead, R&D Lab
"We’re testing the Pro Model (IP67) in an outdoor pilot reactor station with high moisture exposure. After five months, not a single ingress issue. The WiFi capability enables remote tuning without exposing staff to hazardous zones. The 1.5 GHz processor handles our complex PID algorithms with ease. This is the first integrated HMI/PLC that didn’t require external signal conditioning for Pt100 sensors."

Purchase Date: March 2025 | Usage Period: 4 months

🛠️ Small-Scale Workshop Integration

⭐⭐⭐⭐☆ Tom Reynolds - DIY Automation Enthusiast & Small Fabricator
"Bought the Base Model for my CNC cooling system automation. Was skeptical about programming, but the integrated HMI made setup surprisingly simple. Used the USB port to log data to a flash drive for thermal profiling. Build quality feels industrial despite the compact size. Only downside? The manual could use more beginner-friendly examples. That said, YouTube tutorials filled the gap."

🏆 Industry Expert Recommendations

Industrial Automation Consultant Recommendation

Mark Lin - Senior Automation Consultant, FactorySmart Solutions
"In my 15 years of system integration, the Coolmay EXGG-50KH stands out for its true all-in-one design. By combining PLC logic, HMI, and precision analog input in one CE-certified unit, it reduces panel space and wiring complexity by up to 40%. I now recommend it for mid-tier automation projects where cost and reliability are balanced—especially the Advanced Model for multi-device environments."

Process Control Engineer Recommendation

Nina Patel - Lead Engineer, Industrial Controls Institute
"The ±0.5°C Pt100 accuracy with built-in cold junction compensation outperforms many standalone temperature controllers. When paired with the HMI’s real-time trending, it becomes a powerful tool for process validation. For facilities upgrading from relay-based controls, this is a smart entry point into digital process management."
