Shaanxi YuanShengHeTong Refrigeration Co., Ltd. stands as a beacon of excellence in the Chinese PIR/PUR sandwich panel industry. As a leading China Sandwich PIR Panel Factory, we integrate 27 years of manufacturing prowess with cutting-edge engineering services.
Our scope extends beyond simple fabrication; we provide holistic project designs, precision installation, and global logistics support for industries ranging from pharmaceutical storage to large-scale food processing hubs.
While standard PU (Polyurethane) has been the industry workhorse, the market is shifting toward PIR (Polyisocyanurate). Why? Information gain reveals that PIR panels offer superior fire resistance (B1 class) and higher thermal stability compared to PUR.
Our advanced automatic split-joint production lines ensure that the PIR core is uniform, reducing thermal bridging and maximizing the energy efficiency of your cold storage facility.
By 2024, the demand for "Green Building" materials has skyrocketed. As a responsible factory, we transitioned in 2023 to become an eco-friendly facility. We utilize low-GWP (Global Warming Potential) blowing agents, ensuring our sandwich panels comply with international environmental standards, including the Montreal Protocol.
The introduction of our second advanced automatic production line in 2020 has revolutionized our output quality. Automation ensures that the steel sheets and the PIR core are bonded with millimetric precision, preventing delamination—a common failure in lower-tier factories.
Global buyers are no longer looking for just panels. They need a complete ecosystem. We have optimized our supply chain to provide not only the panels but the condensing units, compressors, and cold room doors in a single, coordinated shipment. This reduces site integration errors and lowers total project costs.
Our 60,000 square meter site features 4 standardized workshops and high-efficiency production lines for PIR and PU panels, doors, and refrigeration units.
Founder initiates business in refrigeration marketing and professional installation.
First factory completed in Shaanxi; launched our proprietary cam-lock sandwich panels.
Major relocation to a 120-acre facility with 8 advanced workshops to support international trade.
Implementation of the first automatic split-joint production line, enhancing panel structural integrity.
Second automatic line commissioned, reaching record productivity and quality benchmarks.
Full transition to "Eco-Friendly Factory" status with a focus on sustainable manufacturing.
Our R&D department is currently focusing on three key technical areas to maintain our competitive edge as a top-tier China Sandwich PIR Panel Factory:
Our products carry CE certification and ISO 9001 quality management stamps, ensuring reliability for international procurement.
A: PIR (Polyisocyanurate) is a chemically enhanced version of PUR. The primary difference is fire resistance. PIR panels can withstand higher temperatures and form a protective char layer, making them safer for industrial applications.
A: At YuanShengHeTong, we employ a 10-person QC team that monitors everything from raw material chemical ratios to the final cam-lock alignment. Every batch is tested for density and thermal conductivity before shipping.
A: Yes. Our panels are designed for precise temperature control. When combined with our Copeland-based condensing units, they maintain the strict +/- 0.5°C variance required for vaccines and medical supplies.
A: Cam-locks allow for rapid, modular assembly without the need for complex structural framing. This is ideal for walk-in coolers and cleanrooms where hygiene and fast installation are priorities.
