HANGZHOU — Since the end of the Spring Festival holiday, Shen Yafeng, operations manager at Thermofin Heat Exchanger (Pinghu) Co Ltd, has been busy overseeing the construction of the company's two new plants.

Upon completion, the production area is expected to quadruple, enabling it to efficiently handle substantial orders.

Thermofin is a German-funded enterprise specializing in high-end heat exchangers, and its products are mainly used in indoor ski resorts, high-end cold storage and other industries. In 2018, the company established a factory in Pinghu, East China's Zhejiang province.

"At first, we rented a 5,000-square-meter factory in the Pinghu economic and technological development zone, hoping to gradually expand in the Chinese market by localizing our production," said Shen, adding that he did not expect the Chinese factory to reach an output value of 20 million yuan ($2.78 million) in just a single year.

Since then, the annual output value of the company's Pinghu branch has soared, nearly doubling on average every year.

Thermofin's rapid growth in China can be attributed to the strong integrated support of technologies, market demand and production capacity. "We have core technologies in rapid cooling and precise temperature controls, including the ability to keep the minimum temperature difference of large cold storage at no more than 0.1 C," Shen said.

"These technologies give us an advantage in the construction, operation and maintenance of high-end commercial ultra-cold storage and data center cooling," Shen added.

Combining cutting-edge technologies with China's efficient and dynamic production capabilities, many foreign companies like Thermofin have opted to expand their investment in the country.

In 2023, Thermofin initiated a plan to build new factories and its Asia-Pacific regional headquarters in China, with an estimated investment of 155 million yuan.

"We chose to acquire land to build a factory while further improving employee training. This proves that we attach great importance to the Chinese production base and the Chinese market," Shen said.

Over the years, the Pinghu zone has attracted over 300 foreign-funded enterprises, with intelligent manufacturing of advanced equipment and biotechnology being key industries. Many foreign companies have expanded their investments and production there.
