Company Introduction

DANTE Environmental Technology Co., Ltd. is a national high-tech enterprise specializing in the design, development, and manufacturing of heat pump systems. Serving global markets, DANTE provides professional heat pump solutions ranging from product customization to complete system applications for brand owners, distributors, and system integrators.

The company operates modern manufacturing facilities with a combined floor area of approximately 20,000 square meters. In 2023, to support expanding international business and the growing demand for high-end residential heat pump solutions, DANTE established a new production and R&D facility in Sihui, Guangdong. This facility primarily focuses on products for global export markets as well as high-end residential applications such as villas and apartment buildings.

Meanwhile, the original manufacturing base continues to focus on the Chinese domestic market, supplying heat pump systems for commercial applications and large-scale residential heating projects, including government-led coal-to-electric heating replacement programs.

The new Sihui facility is equipped with dedicated R&D laboratories, full operating-condition performance testing platforms, and advanced automated production lines. A quality management and production control system compliant with ISO 9001 and other international standards has been established, providing a solid foundation for stable, high-quality, large-scale OEM / ODM cooperation.
