Company Profile
Henan Hengze Environmental Protection Technology Co., Ltd. is a professional domestic organization engaged in the recycling of waste resources (waste plastics, waste rubber, aluminum-plastic, circuit boards, waste engine oil). Located in Shangqiu, Henan, the company benefits from convenient transportation and rapid economic development. After years of technical breakthroughs, we have developed intermittent, semi-continuous, and 24-hour full-continuous pyrolysis equipment, complete with desulfurization and denitrification systems, on-line dust monitoring systems, and carbon black vacuum air conveying collection systems.
Batch cracking equipment can process up to 5-15 tons per day. Fully automatic continuous cracking equipment can handle 20-100 tons per day, with equipment meeting emission standards. The company's small skid-mounted (1-3 tons) cracking and distillation equipment is easy to operate. The distillation equipment, equipped with an automatic PLC or DCS control system, achieves continuous operation with a daily processing capacity of up to 200 tons.
The company adheres to the principle of "A Promise Is as Good as Gold," ensuring product quality. Currently, products are sold domestically in Zhejiang, Anhui, Shandong, Chongqing, Xinjiang, Fujian, and other provinces. Internationally, exports have reached the United States, South Korea, the United Kingdom, Spain, Belgium, and many other European locations, as well as over 20 countries in South America, Africa, and the Indian subcontinent.
