In the modern industrial landscape, Composite Foam Sandwich Panels have emerged as the cornerstone of energy-efficient architecture. These panels are not merely building materials; they are engineered systems designed to mitigate heat transfer, ensure structural integrity, and provide fire resistance in critical environments. As an OEM manufacturer, Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. has observed a seismic shift in global demand toward PIR (Polyisocyanurate) and PUR (Polyurethane) cores.
The "Sandwich" architecture—consisting of two rigid metal skins and a high-density foam core—offers a strength-to-weight ratio that traditional masonry or timber cannot match. For the cold storage, pharmaceutical, and cleanroom industries, the focus has transitioned from simple insulation to Semantic Thermal Performance. This means analyzing how panels perform under extreme pressure, humidity, and temperature differentials over a 20-year lifecycle.
Global trends indicate a move toward "Passive Design" where the building envelope does the majority of the cooling work. Our panels are at the forefront of this movement, integrating cam-lock systems for airtight seals and FM-approved fire ratings to meet the stringent safety requirements of the European and North American markets.
Shaanxi YuanShengHeTong Refrigeration Co., Ltd. is a professional factory and enterprise focusing on insulation panels and refrigeration equipment. Since 1996, we have integrated high-quality products, one-stop project solutions, and international trade to provide customers with excellent products and satisfied services.
Our expertise spans the refrigeration of fruits, vegetables, food industry, large supermarkets, medical, and logistics companies. With more than 20 years of experience, we operate from a 60,000 square meter production site with 4 standardized workshops and advanced automated production lines.
Our automatic split-joint production lines (commissioned in 2018 and 2020) ensure that every PIR/PUR sandwich panel has a uniform core density, preventing "thermal bridges" that cause energy leakage.
With a dedicated 10-person QC team, we conduct rigorous testing on thermal conductivity, compressive strength, and fire retardation to maintain our CE Certification standards.
Located in the industrial heart of Shaanxi, we leverage China's robust infrastructure to offer shorter lead times and resilient supply chains for global procurement needs.
Founder started in refrigeration equipment marketing and installation.
First factory completed in Shaanxi; first cam-lock sandwich panels produced.
Relocation to a 120-acre field with 8 advanced workshops for international business.
Commitment to sustainability; transitioned into an eco-friendly manufacturing factory.
Optimizing PIR foam core panels for massive distribution centers in Europe and SE Asia to minimize electricity costs.
Ultra-clean sandwich panels for pharmaceutical storage where temperature precision is a matter of life and death.
Durable roof panels with PIR cores designed for industrial factories, providing both insulation and weatherproofing.
While both are polyurethane-based, PIR (Polyisocyanurate) features higher thermal stability and superior fire resistance due to its chemical ring structure. PIR is often the choice for projects requiring strict insurance compliance.
The Cam-Lock mechanism allows panels to be mechanically pulled together, creating a tight, seamless joint. This eliminates thermal leaks common in tongue-and-groove systems, essential for sub-zero cold storage.
Yes. As a primary OEM manufacturer, we customize panel thickness (50mm to 200mm), skin material (Stainless steel, PPGI, Aluminum), and foam density to meet specific R-value requirements.
Our products are CE Certified and undergo ISO 9001:2015 quality management. We ensure all exported panels meet the local structural and environmental codes of the destination country.
