Shandong Huahai Refrigeration Equipment Co., Ltd. was established in 2021 and is located in Weifang, Shandong Province, a national comprehensive transportation hub city and the World Kite Capital. The company’s main products include screw parallel refrigeration units, barrel pump units, air coolers, and evaporative condensers. The company distributes world-renowned compressors: Germany’s Bitzer, Italy’s Refcomp, Italy’s Frascold, Taiwan’s Fusheng, and Taiwan’s Hanbell. It adopts world-famous brand accessories, including Germany’s Siemens, France’s Schneider, Denmark’s Danfoss, and Italy’s Carel. The control system of the screw parallel unit is independently programmed. After years of optimization and version updates, the system has become increasingly user-friendly, convenient, and intelligent. It supports integrated control of the cold storage and the main unit, enabling easy operation. The system features real-time clock refrigeration, allowing each cold storage to operate independently during off-peak electricity periods to save power costs. The compressors run automatically and evenly, ensuring uniform wear. All products are equipped with a remote control system as standard, which greatly saves customers’ maintenance time, labor, and travel costs. The company always considers issues from the customers’ perspective, addresses every detail of the products, and strictly controls product quality. The products feature advanced design concepts, stable materials, long service life, and excellent reliability.
