Shaanxi YuanShengHeTong Refrigeration Co., Ltd. is a premier professional factory and enterprise specializing in advanced insulation panels and comprehensive refrigeration systems. Operating since 1996 with over 20 years of dedication, we integrate high-quality manufacturing, one-stop engineering solutions, advanced project installation, and international trade excellence.
Our core business ranges across temperature-controlled storage for agricultural fruits and vegetables, the food processing industry, large supermarket chains, commercial hospitality venues, pharmaceutical logistics, and medical cold chains.
In the current global economic landscape, industrial cold chain logistics and green building standards demand uncompromised thermal insulation performance. PU (Polyurethane) and PIR (Polyisocyanurate) sandwich panels represent the gold standard in structural thermal envelopes.
Our CE-certified sandwich panels provide superior fire-retardant properties, structural integrity, and extremely low thermal conductivity (lambda value), ensuring optimal energy conservation in compliance with international green building codes (such as EU EN 14509).
Spanning an expansive production site of 60,000 square meters backed by 4 standardized workshops, our factory operates with a skilled workforce of ~180 professionals and a dedicated 10-person QC inspection team. We utilize state-of-the-art automatic split-joint production lines to guarantee precision, massive output capacity, and strict compliance with ISO9001 quality management standards.
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 larger fields (120 acres with 8 advanced workshops).
With more advanced technology in insulation panel industry, we input our first automatic split-joint production line.
Our second advanced automatic production line put on stream, reaching higher productivity and superior quality.
Embracing sustainability, we transitioned into an eco-friendly smart manufacturing facility.
Our polyurethane (PUR/PIR) sandwich panels utilize high-pressure foaming technology with pentane (environmental foaming agent), achieving a closed-cell rate exceeding 97%. This structural density prevents moisture ingress, minimizes thermal bridge effects, and guarantees enduring insulation performance over decades.
Meeting rigorous international standards, our manufacturing processes and product lines are fully validated by CE certification, ISO standards, and environmental safety protocols. We offer complete documentation and third-party testing reports to fast-track regional customs clearance and engineering approvals worldwide.
From tropical regions requiring high humidity barriers to frigid alpine zones demanding extreme sub-zero structural retention, our technical consultants provide tailored engineering configurations. We offer comprehensive installation guides, cam-lock technical support, and turnkey commissioning assistance.
Our sandwich panels undergo strict independent testing regarding structural loading, thermal transmittance, and fire performance in compliance with European Union standards (EN 14509), ensuring full legal compliance for international construction projects.
Yes, as a direct factory manufacturer, we offer customized panel lengths, varying thicknesses (from 50mm to 200mm), and multiple skin options (PPGI, Stainless Steel, Aluminum) tailored to your exact cold storage specifications.
Thanks to our 4 automated production lines spanning a 60,000 sqm facility and a stable workforce, standard production and container loading are efficiently handled within 15 to 25 business days depending on project volume.
