16 Years of Excellence: Premium Coolers for Wine, Beverages, Cigars, Meat & Medical Use
Since 2010, Sunnai has been a professional manufacturer of compressor refrigeration equipment. With 16 years of industry experience and technical expertise, we are dedicated to delivering high-quality and reliable cooling solutions. While we specialize in premium wine coolers, our extensive product line also includes beverage coolers, cigar humidors, dry agers, medical refrigerators, and beer kegerators. Offering a wide range of models and specifications, we perfectly meet the diverse needs of homes, restaurants, and commercial spaces. Above all, we deeply value and respect the trust every customer places in us.
Before assembly, 100% of our electrical boards must pass a rigorous 12-hour temperature stress test—enduring -25°C, 45°C, and room temperature for 4 hours each. Following this, every board undergoes a strict final performance check to guarantee maximum stability and reliability.
การสอนการเชื่อมโลหะโดยผู้มีประสบการณ์
ในส่วนของกระบวนการเชื่อม เราได้เชิญวิศวกรที่มีประสบการณ์ด้านการเชื่อมที่ BMW ประเทศเยอรมนีมาเป็นเวลา 25 ปี มาควบคุมดูแลการทำงาน และผลลัพธ์ที่ได้คือ อัตราความล้มเหลวจากการรั่วซึมของผลิตภัณฑ์ของเราต่ำกว่า 0.1%
Multiple Measures to Protect the Appearance
Our automated production line ensures precision and care at every step. Casings are safely transported by tool trolleys, and post-assembly units are sent via conveyor belts for cooling tests. To prevent handling scratches, we use vacuum suction lifters during packaging. Once fully packed, all units are automatically conveyed to the warehouse.
We simulate diverse environmental conditions during testing to ensure optimal real-world performance. This comprehensive approach allows us to continuously refine and tailor our products to meet the specific demands of various global markets and distribution channels.
Multiple Product Quality Tests
We always believe that only strictly tested products can meet our customers’ expectations and win us a good reputation in the market. Our products have to go through several critical tests, the first cooling test, the second HI-POT test, the third product configuration double-check, the fourth performance test, and the fifth high voltage test.
