As Japan's third-largest metropolitan area, Nagoya (Aichi Prefecture) stands as a global titan in manufacturing, particularly in the automotive, aerospace, and robotics sectors. The Port of Nagoya, being Japan's busiest port in terms of total cargo throughput, creates an unprecedented demand for sophisticated logistics and cold-chain infrastructure.
Our sandwich panels are engineered to meet the stringent Japanese building codes (Building Standards Act) and the specific thermal requirements of the Chubu region. Whether it is a temperature-controlled automotive components warehouse in Toyota City or a seafood cold storage facility near Nagoya Port, our PIR/PUR panels provide the thermal resistance (R-value) and fire safety ratings necessary for modern Japanese industrial architecture.
In the context of Nagoya's humid subtropical climate, insulation choice is critical for operational cost reduction. PIR (Polyisocyanurate) panels offer superior fire resistance and a higher thermal stability compared to traditional PUR (Polyurethane). For high-tech manufacturing facilities in Nagoya, PIR is the gold standard, offering an Lambda value as low as 0.019 - 0.022 W/m·K.
Our Shaanxi factory utilizes the latest high-pressure foaming technology to ensure uniform cell structure within the panel core. This prevents "thermal bridging" and ensures that large-scale facilities—such as those found in Komaki or Ichinomiya—maintain constant internal temperatures with minimal energy expenditure.
Shaanxi YuanShengHeTong Refrigeration Co., Ltd. is a professional factory and enterprise focusing on insulation panels and refrigeration equipment. Besides product manufacture, we also provide services like project design, construction, installation, as well as after-sales service.
We integrate "high quality products, one-stop project solution, engineering advanced services, and international trade" to provide customers with excellent products and satisfied services. Our involved professional fields include refrigeration of fruits, vegetables, food industry; also refrigeration of large supermarkets, restaurants, hotels, medical and logistics companies etc.
Our business in refrigeration fields started in 1996, with more than 20 years experience in refrigeration industry, we are confident in our professionality. And our factory is specializing in refrigeration manufacturing and technology.
With about 180 workers and 10 QC team, the quality and efficiency are guaranteed of our products. And we are always aiming for higher quality products and better service.
Now, the factory has an existing production site of 60,000 square meters, 4 standardized workshops, high quality and efficient production equipment, as well as advanced production lines and techniques. Our factory mainly produces PIR(Polyisocyanurate) and PU(Polyurethane) sandwich panels, cold storage doors, air coolers, condensers, condensing units, compressor units etc.
By leveraging China's advanced industrial supply chain and our own 60,000 sqm facility, we achieve production speeds 30% faster than localized Japanese manufacturers. This is crucial for rapid-response projects in the fast-paced Nagoya market.
Strategic sourcing of raw materials and optimized labor efficiency allow us to offer premium PIR/PUR panels at a significant competitive advantage without compromising on Japanese quality standards.
With a dedicated 10-person QC team and CE certification, every panel undergoes strict testing for density, fire resistance, and dimensional accuracy before shipping to Nagoya Port.
