The 10 cm (100mm) continuous Polyurethane (PUR) and Polyisocyanurate (PIR) core delivers an extraordinarily low thermal conductivity rating of λ ≤ 0.020 W/m·K. This specific depth achieves optimal thermal resistance (R-Value ~ 5.0 m²·K/W), preventing heat ingress in cold storage environments operating between -5°C and -25°C.
Featuring precision-engineered eccentric cam-lock systems integrated directly into the core foam density of 40-42 kg/m³. This tongue-and-groove joint geometry ensures an airtight mechanical seal, eliminating thermal bridging and vapor leaks across panel seams under high structural flexure.
Manufactured using self-extinguishing PIR formulations compliant with DIN 4102 B1 and EN 13501-1 B-s2,d0 standards. Under flame contact, the material forms a stable protective carbonization layer that inhibits flame propagation and toxic gas generation in industrial cleanroom or warehouse settings.
In thermal design engineering, selecting panel thickness is a balance between initial capital expenditure (CAPEX) and long-term refrigeration operational expense (OPEX). While 5 cm panels are ideal for simple partition walls and 15 cm+ panels are reserved for deep ultra-low blast freezers (-35°C), the 10 cm (100mm) sandwich panel serves as the sweet spot for the vast majority of commercial logistics facilities, pharmaceutical cold rooms, and agricultural storage hubs.
By specifying a uniform 100mm PUR/PIR core with double-sided prepainted galvanized steel (PPGI) or SUS304 stainless steel facings (0.4mm to 0.8mm thickness), facility owners maximize internal cubic volume while reducing compressor duty cycles by up to 35% compared to conventional insulation materials like Expanded Polystyrene (EPS).
A trusted global manufacturer and turnkey engineering service provider with over two decades of technical leadership in commercial refrigeration technology.
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.
Understanding shifting global demand across cold chain hubs and the strategic advantages of China's automated manufacturing footprint.
Driven by stringent Net-Zero targets and rising energy costs, procurement in North America and Western Europe is prioritizing high R-value insulation. 10 cm PIR panels equipped with eco-friendly pentane blowing agents satisfy both local fire codes and high thermal resistance standards without excessive structural weight.
Rapid urbanization, agricultural export hubs, and expanding pharmaceutical supply chains in tropical regions demand heavy-duty, humidity-resistant insulation. 10 cm PUR/PIR panels prevent condensation risks even when ambient exterior temperatures exceed 45°C with relative humidity over 85%.
By integrating automated continuous double-belt production, automated chemical dosing, and high-volume raw material procurement, Shaanxi YuanShengHeTong offers global buyers up to 30% cost efficiency while maintaining absolute compliance with ISO and CE technical specifications.
Designed for multi-sector versatility across temperature-sensitive storage and processing infrastructure.
Maintains target temperatures (+2°C to +8°C) for post-harvest fruit and vegetable preservation, preventing moisture loss and extending shelf-life in agricultural distribution hubs.
Complies with strict GMP standards. The non-porous, smooth steel surface prevents bacterial growth and chemical degradation during intense sanitization protocols.
Resists internal humidity cycles and thermal shocks during blast freezing (-20°C). Keeps structural rigidity even under high operational traffic and ceiling weight suspended loads.
Forms modular walk-in coolers and multi-zone distribution centers. Features rapid cam-lock assembly to drastically reduce on-site construction timelines and labor costs.
Over 25 years of technological innovation, expanding footprint, and sustainable manufacturing evolution.
Our founder started the business from refrigeration equipment marketing and installation.
With our first factory completed in Shaanxi, we produced our first cam-lock sandwich panels.
The second factory in LanZhou completed, our business started to cover the whole north-west market in China.
Follow with larger business and international business, the Shaanxi factory relocated to a larger fields, now we possess with 120 acers area with 8 advanced workshops.
With more advanced technology in insulation panel industry, we input our first automatic split-joint production line. Here the new chapter begins.
Our second advanced automatic production line put on stream, we reach to a higher productivity and efficiency with better quality.
With the responsibility of sustainability, we are now moving into an eco-friendly factory.
Strict quality control processes backed by international certification standard compliance.
Integrated OEM components designed to pair seamlessly with 10 cm sandwich panels for total thermal system integrity.

A 10 cm (100mm) PUR or PIR sandwich panel is globally optimized for operating temperatures between -5°C and -25°C. This makes it ideal for commercial freezer rooms, meat and seafood storage, dairy cold chains, and pharmaceutical logistics. For extreme deep-freeze applications below -30°C, 15 cm or 20 cm panels are typically specified.
PUR (Polyurethane) provides high thermal insulation and excellent mechanical bonding to steel skins. PIR (Polyisocyanurate) is a modified chemical variant featuring higher ring structure stability, providing superior fire resistance (class B1/B2, self-extinguishing) and higher thermal stability while maintaining equivalent thermal conductivity ratings.
The cam-lock mechanism consists of built-in steel locking hooks along panel edges that pull adjacent panels tightly together during installation. This creates a high-pressure seal, eliminates thermal bridging, reduces cold air leakage, and allows modular assembly or disassembly without heavy structural welding.
Shaanxi YuanShengHeTong provides custom steel facing options (0.4mm–0.8mm PPGI, stainless steel 304, embossed aluminum), variable lengths up to 12 meters, custom color matching (RAL range), surface profiling (ribbed, flat, micro-rib), and pre-cut conduit channels for specialized electrical routing.
Panels are lined with protective polyethylene film on both steel faces, bundled into heavy-duty wooden pallet skids, wrapped with shrink film, and fitted with corner guards to prevent mechanical edge deformation during container loading, sea transport, and site unloading.
With 60,000 m² of factory space, 4 standardized workshops, 20+ years of technical experience (est. 1996), and dedicated continuous production lines, we provide direct factory pricing, absolute quality control, fast lead times, and comprehensive turnkey engineering design services for global importers.
