Shandong Qinglei Environmental Technology Co., Ltd,Established in Jinan, Shandong in 2012, it is a comprehensive enterprise integrating the research and development, production, and sales of products such as heat exchangers, heat exchange units, and pressure vessels. In February 2019, through the shareholding reform, the company successfully listed on the New Third Board (stock code: 873193)

Since its establishment, Qinglei Technology has always been innovation oriented in solving customer problems,Accumulate services to various types of enterprises3000+, undertaking various projects over2000+has solved a series of problems in China's distillation and wastewater desalination fields, providing strong technical support for energy conservation and emission reduction in pharmaceutical and chemical enterprises at home and abroad, and also contributing to China's blue sky and clear water cause.

At the end of 2016, the new factory of Qinglei Technology was put into use, with two large production bases in the south and north, three modern production workshops, a building area of 15900 square meters, and a land area of more than 50 acres.The southern base isTwo heat exchanger production workshops, with the northern base serving as the production workshop for heat exchange unit equipment and pressure vessel equipment.The production and processing center has over a hundred intelligent equipment such as laser cutting, automatic welding, CNC machining, CNC drilling and milling machines, CNC lathe machining, and intelligent robotic arms, achieving product production from waterjet cutting-Fully automated processing and production of head wire cutting, tube sheet CNC machining, tube welding, shell welding, weld seam, water sandblasting, ring and corner welding to meet customers' quality requirements for product quality, equipment schedule, welding process, and other aspects.

Qinglei Technology possessesD1/D2 pressure vessel design and manufacturing qualifications have successively passed ISO9001, 14001, 18001 and other system certifications. By increasing research investment, introducing scientific researchers, and closely communicating and cooperating with colleges and universities, we continuously innovate and gradually upgrade from producing individual heat exchange equipment to automated complete sets of equipment. We have developed and produced a series of innovative equipment with independent intellectual property rights in temperature control systems, evaporation, concentration, distillation, crystallization, drying, and other aspects, and have become a training base for college students at Ocean University of China.

Qinglei Technology has a rich and diverse product line, including heat exchanger units such as spiral wound tube heat exchangers, spiral baffle heat exchangers, double tube plate heat exchangers, column tube heat exchangers, silicon carbide heat exchangers, inner fin heat exchangers, plate heat exchangers, and spiral plate heat exchangers; The complete set of equipment includes: heat exchange unit, precise temperature control unitTCU、 Distillation bed, desalination machine, SDR system, etc; And various non-standard equipment can be produced according to customer needs, such as pressure storage tanks, reactors, towers, etc.Breakthroughs have been made in the research and development of various products, including solvent recovery and purification, industrial wastewater treatment, and saltwater treatment.All products can provide customers with one-stop services covering engineering consulting, scheme design, equipment manufacturing, installation and commissioning, operation management, maintenance and repair.

In addition to individual heat exchanger products, we also customize and produce complete sets of equipment for customers, including traditional Chinese medicine extraction and concentration systems, reaction kettle distillation reflux systems, gas heat exchange systems, food and beverage systems, tower top cooling and waste heat systems, vacuum distillation systems, exhaust gas recovery systems, heating systems, etc. We provide customers with efficient, energy-saving, and stable heat exchange solutions that are resistant to high and low temperatures, corrosion, gas and gas heat exchange, gas-liquid heat exchange, and liquid-liquid heat exchange.
