Pioneering high-R-value thermal barriers engineered to withstand Antigua and Barbuda's coastal salt-air and high-humidity environments.
Antigua and Barbuda's economy, heavily driven by luxury tourism, yachting, and fisheries, faces unique logistical challenges. The island nation depends strongly on imported foods and perishable products to feed both local residents and international visitors in top resorts. Maintaining an uninterrupted cold chain from St. John's deepwater harbor to resort kitchens is crucial.
However, the local environment is extremely demanding. High relative humidity (frequently exceeding 80%), elevated coastal salt spray, and high electricity rates require cold storage infrastructure that delivers maximum thermal efficiency and structural durability.
The Solution: Heavy-duty, hermetically sealed Cold Storage Doors and high-density polyisocyanurate (PIR) core panel systems. Our high-R-value products are specifically engineered to eliminate thermal bridging, stop condensation, and withstand the corrosive marine atmosphere of the Caribbean.
Inquire for Local ProjectsEquipped with SUS304/SUS316 stainless steel tracks and corrosion-proof hardware, ensuring door mechanisms do not rust or fail under saline conditions.
PU and PIR core density of up to 42 kg/m³ provides superior thermal resistance, drastically lowering electric bills in high-tariff island regions.
Dual-gasket perimeter sealing and integrated heating wires prevent frost accumulation and humidity infiltration along door seams.
Professional Manufacturer & One-Stop Cold Storage Solution Provider since 1996.
Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. is a leading enterprise focusing on top-tier insulation panels, cold storage doors, and commercial refrigeration machinery. Beyond product manufacturing, we provide complete engineering support, including project design, custom layouts, structural calculation, installation guidance, and overseas after-sales service.
We integrate "high-quality products, one-stop project solutions, advanced engineering service, and global logistics" to deliver outstanding results. Our systems are widely used in agriculture, seafood processing, large supermarkets, hospitality groups, resort complexes, medical facilities, and distribution hubs across the Americas, Europe, and the Caribbean.
Connect with an EngineerTechnical specifications and material features designed to deliver long-term reliability in high-temperature, high-salinity zones.
Constructed with high-density polyurethane (PU) or polyisocyanurate (PIR) foam injected at high pressure between metal sheets. Total thickness options: 100mm, 120mm, or 150mm. Outer skins feature pre-painted galvanized steel (PPGI) with PVDF coating or Marine-grade SUS304/SUS316 stainless steel to prevent salt-fog corrosion.
Features co-extruded EPDM gaskets that resist UV rays and mechanical wear. Integrated self-regulating heating cables (220V or 110V options) run along the door frame profile, preventing seal freezing and ensuring smooth operation in sub-zero applications down to -40°C.
Available in manual sliding, vertical lift, and automated electric configurations. Automated systems utilize variable frequency drives (VFD) for soft-start and soft-stop functionality, reducing mechanical shock and prolonging structural life in high-traffic food distribution points.
With over 180 skilled factory workers and a 10-member Quality Control team, we maintain strict control over every stage of manufacture. We focus on continuous engineering progress to supply long-lasting cold room solutions worldwide.
Our production facility covers 60,000 square meters across 4 standardized workshops, utilizing advanced continuous panel laminators, automated foaming machines, and heavy-duty sheet bending machinery. This allows us to produce high-density PIR/PU sandwich panels, heavy-duty sliding doors, swing doors, and high-efficiency evaporator/condenser coils.
From a regional installer to a global industrial refrigeration brand over three decades.
Our founder started the business in refrigeration equipment marketing and local installation services.
Completed our first dedicated factory in Shaanxi, successfully manufacturing our first range of cam-lock insulation sandwich panels.
Opened our second factory in Lanzhou, expanding our supply network across Northern and Western China.
Relocated Shaanxi production to a larger 120-acre facility, housing 8 advanced workshops for increased industrial scale.
Invested in our first automated continuous double-belt sandwich panel production line, significantly boosting structural panel quality.
Commissioned our second advanced automated panel production line, establishing higher efficiency and capacity for international orders.
Adopted green manufacturing technologies, transitioning to eco-friendly raw materials and blowing agents to support global sustainability initiatives.
To ensure our cold storage solutions meet the strict engineering and safety standards of Antigua and Barbuda, our manufacturing process complies with international building and safety standards. Our continuous quality control programs ensure that every panel and door operates reliably under high temperature and humidity.
✓ CE Certification: Our cold room door systems and electric drives are fully certified for safe operation and build quality.
✓ ISO 9001:2015: Factory processes follow verified quality management guidelines from raw materials to final packaging.
✓ Fire Performance: PIR sandwich panels are formulated to meet international B1/B2 fire classification standards, providing excellent flame retardancy.
