⭐ Customer Reviews and Testimonials

Authentic User Feedback

🔧 Industrial Maintenance Engineer Reviews

⭐⭐⭐⭐⭐ James Peterson - Industrial Maintenance Engineer
"Installed the Kriwan INT69 SCY in our cold storage facility back in February 2025, and it’s been rock-solid. We operate at -25°C regularly, and this protector handles the thermal stress without a hitch. The CE certification gave us peace of mind for compliance, and the 22 A rated current is perfectly matched to our compressors. No trips, no failures—just reliable protection."

Purchase Date: February 2025 | Usage Period: 6 months

🧊 Commercial Refrigeration Technician Reviews

⭐⭐⭐⭐⭐ Lena Müller - Refrigeration Technician, Supermarket Chain
"We’ve had multiple motor failures in our display chillers before switching to the INT69 SCY. Since installing it across 12 units in late 2024, zero compressor burnouts—that’s unheard of for us. The phase sensor caught an imbalance during a power surge last month and shut things down safely. German engineering really shows in the build quality and precision."

Purchase Date: November 2024 | Usage Period: 8 months

🏭 Manufacturing Plant Operations Manager Reviews

⭐⭐⭐⭐☆ David Tran - Operations Manager, Food Processing Plant
"We needed something rugged for our outdoor chiller units exposed to dust, humidity, and wide temperature swings. The industrial-grade plastic housing has held up better than expected—even after summer heatwaves. Installation was straightforward thanks to the multi-terminal setup. Only reason I’m not giving five stars is that we had to request a custom voltage threshold adjustment, which took two weeks to finalize."

Purchase Date: April 2025 | Usage Period: 4 months

🌐 HVAC System Integrator Reviews

⭐⭐⭐⭐⭐ Elena Rodriguez - HVAC System Integrator
"As a system integrator, I work with dozens of motor protectors, but the Kriwan INT69 SCY stands out for its modular design and voltage flexibility. Used it in a mixed-use building with fluctuating grid supply—its ±15% input tolerance prevented nuisance tripping. Also appreciate the compact footprint; fits neatly in tight control panels. Will be specifying this model on future projects."

Purchase Date: January 2025 | Usage Period: 7 months

❄️ Cold Storage Facility Engineer Reviews

⭐⭐⭐⭐⭐ Arjun Patel - Facility Engineer, Frozen Logistics Center
"Our previous protectors failed repeatedly below -20°C. The -30°C to +60°C operating range of the INT69 SCY solved that overnight. Installed it in January 2025, and through three deep-freeze cycles and summer load peaks, it hasn’t missed a beat. The C300 relay feels overbuilt in the best way—confident it’ll last years. If you run industrial refrigeration, this is the standard now."

🏆 Industry Expert Recommendations

Refrigeration Safety Expert Recommendation

Dr. Henrik Vogt - Industrial Refrigeration Safety Consultant
"The Kriwan INT69 SCY sets a new benchmark for compressor protection in commercial and industrial settings. Its combination of overcurrent protection, phase monitoring, and extreme temperature resilience exceeds IEC 60947 standards. I recommend it for any operation where refrigeration uptime is critical—especially in environments with unstable power or sub-zero conditions."

Electrical Systems Engineer Recommendation

Maria Ivanova - Senior Electrical Systems Engineer
"Having evaluated dozens of motor protection relays, I’m impressed by the INT69 SCY’s adaptive voltage handling and robust relay output (2.5 A, C300). It outperforms typical protectors in real-world voltage fluctuations. For facilities without dedicated stabilizers, this unit’s -15% to +10% tolerance is a game-changer. A reliable, future-proof choice."
