Delivering reliable compressor refrigeration and expert manufacturing solutions since 2010.
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.
Sunnai’s superior competence and experience allow us to provide the right solution for OEM or ODM orders.
Although it will affect the production efficiency, it can better ensure the quality.
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.
In terms of welding operations, we have invited an engineer who has been involved in welding at BMW in Germany for 25 years to supervise the work, and as a result, the leakage failure rate of our products is less than 0.1%.
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.
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.
The quality inspection tracking card is a measure to strictly control the quality of our products. It records in detail the whole process of the product from raw material purchase, production and processing, finished product testing to shipment.
Based on the principles of sincerity, co-operation and innovation
