About Us
Environmental and Reliability Test Equipment Manufacturer
Founded in 1995, SANWOOD Technology designs and manufactures environmental test chambers and reliability test systems. We provide standard equipment and customized solutions for R&D, product qualification and production screening, supporting applications from individual components to complete products and systems.
Our approximately 30,000 m² manufacturing facility in Dongguan, China, combines engineering, production, assembly and quality control. SANWOOD’s management systems are certified to ISO 9001:2015 and ISO 14001:2015, and our product portfolio includes SGS-certified and UL Mark-certified equipment.
Our range covers temperature and humidity chambers, thermal shock chambers, ESS rapid temperature cycling chambers, altitude chambers, combined temperature-humidity-vibration chambers and walk-in environmental test facilities. HAST chambers, temperature forcing systems and memory burn-in systems address semiconductor and electronics reliability testing, while battery test chambers, xenon weathering chambers and UV aging chambers support energy storage and material durability evaluation.
SANWOOD serves manufacturers, research institutions and testing laboratories in more than 100 countries and regions. Our applications span semiconductors, memory devices, AI servers, electronics, automotive, aerospace, batteries and energy storage. Across these industries, we help customers define equipment configurations around their samples, test profiles and operating requirements.

Our Values
Custom Engineering, Low-GWP Innovation and Global Support
At SANWOOD, understanding the application is the foundation of equipment design. Sample dimensions, heat dissipation, temperature change rates, humidity conditions and electrical interfaces all influence how a test system should be configured.
Our engineers work with customers to turn these requirements into practical solutions. Customization can include chamber dimensions, airflow distribution, heating and cooling capacity, sample racks, fixtures, monitoring functions and safety provisions. We also consider loading procedures, maintenance access and integration with existing test equipment to support everyday laboratory and production workflows.
We invest in refrigeration development to address changing environmental priorities. In response to European demand for lower-GWP refrigerants and reduced refrigerant-related emissions, SANWOOD has developed environmental test chambers using CO₂ (R744) refrigeration. CO₂ is a natural refrigerant with a global warming potential of 1, offering an alternative to conventional high-GWP HFC refrigerants.
Our commitment extends beyond equipment delivery. SANWOOD’s international service network includes locations in Germany, South Korea, Vietnam and Malaysia. Together with remote technical assistance and worldwide on-site support, this network helps coordinate installation, commissioning, operator training, preventive maintenance, repairs, equipment upgrades and relocation.
We value clear specifications, practical engineering and lasting customer relationships. From the first technical discussion through years of operation, our focus is on helping customers establish repeatable test conditions and maintain dependable equipment.
