THT Heat Transfer Technology

What THT Heat Transfer Technology does

THT Heat Transfer Technology is a Chinese industrial manufacturer of plate heat exchangers and integrated heat exchange systems, founded in 1986 and headquartered in Siping, Jilin Province. The company designs and produces gasketed, brazed, and welded plate heat exchangers, packaged skid-mounted heat exchange systems, and associated pressure vessels for district heating, HVAC, power generation, petrochemical processing, metallurgy, marine, food and beverage, and nuclear applications. Reported annual production capacity is 1 million square meters of plate exchangers and 5,000 system units, supported by 165,000 square meters of manufacturing facilities, 12 domestic branches, and 36 service locations. The portfolio includes 70+ national patents (9 invention patents), and the company claims 15 consecutive years of sales leadership in China's plate heat exchanger market with 200,000+ application cases across 108 industries.

The company sells primarily through direct enterprise sales to large industrial and energy customers, supported by an after-sales service network. Named customers include China National Nuclear Corporation (CNNC), China General Nuclear (CGN), Sinopec, CNOOC, BASF, Shell, CATL, and Baosteel, indicating a project-based sales motion into nuclear, petrochemical, and battery supply chains. International reach spans 31 countries. The company is publicly traded on US OTC markets under ticker THTI following a 2010 NASDAQ IPO, although financial reporting has been limited. Certifications include ASME, AHRI, ISO, Nuclear Class 3, and CCS (21-year tenure), which qualify the company for nuclear and marine applications and constitute meaningful regulatory barriers to entry.

In 2024-2025, THT was upgraded to a National Key 'Little Giant' enterprise designation by China's Ministry of Industry and Information Technology and launched a digital transformation initiative incorporating IoT-based product lifecycle management, SCADA remote monitoring, and a cloud-based smart heating platform with stated AI and big data analytics. Recent strategic activity includes a 2025 partnership with CGN to localize nuclear-grade titanium plates, a 2023 joint research initiative with Tsinghua University and Xi'an Jiaotong University on waste heat recovery and CCUS, and a 2021 commissioning of a 50,000-ton hydraulic press for larger-format welded plate capacity. The company serves more than 10,000 enterprise customers.
