At Zhejiang Heneng Ventilation Equipment in the Lishui Economic and Technological Development Zone, production and shipments are in full swing, with overseas orders already scheduled into October.

From January to June this year, the company achieved an output value of 35 million yuan ($5.14 million), including 19 million yuan from exports.

Monthly output in June doubled from the previous month, while annual output has sustained over 50 percent growth for three consecutive years.

Domestic orders are scheduled into September, while overseas orders extend all the way to October, with domestic demand rising 30 percent year-on-year and the peak season significantly lengthened.

Since 2005, the firm has designed over 500 mold sets. It also operates large injection-molding units, enabling in-house production of most components for its evaporative cooling units. Its product line spans industrial fans, mobile coolers, and plastic ventilation ducts, with an annual capacity of one million units.

Exports now reach Southeast Asia, Africa, and Europe. In 2025, exports reached 43 million yuan, with a projected 60 million yuan for 2026.

The company has steadily expanded overseas clients through participation in the biannual Canton Fair, and at this year's fair it secured a trial order from a Brazilian buyer. Its compressor-free, refrigerant-free, and pollution-free coolers are gaining international attention.

Looking ahead, the company plans to invest about 30 million yuan in equipment upgrades and R&D, aiming for broader market reach through continuous innovation.
