Qingdao Jinhua Refrigeration Technology Co., Ltd. has been dedicated to the research and development of the "Wenter" refrigerant recovery and filling machine for 18 years. Over this time, the company has continuously improved its product performance, reaching an advanced level comparable to international standards. The quality of the products is outstanding, and the after-sales service system is highly regarded by both domestic and foreign clients. As a result of its innovative efforts, the company has earned prestigious honors such as “Shandong Province Environmental Protection Advanced Member Enterprise,†“Shandong Province Contract-honoring and Credit-keeping Enterprise,†“Qingdao High-tech Enterprise,†and “Qingdao City Inspection-free Enterprise.â€
In November 2005, Qingdao Jinhua decided to collaborate with well-known local companies, launching a free trial month of the “Wenter Refrigerant Recycling Machine†for Qingdao Haier Industry and Trade Commercial Air Conditioning Co., Ltd., a globally recognized air conditioning manufacturer. This initiative was carried out at Haier’s commercial air-conditioning maintenance outlets, focusing on the environmental campaign “Caring for Life, Protecting the Blue Sky.†The goal was to help users in the air-conditioning after-sales service industry fully understand the excellent performance of the Wenter refrigerant recovery machine — an environmentally friendly and energy-saving new product. Thanks to Haier's strong reputation and high credit rating, the Wenter machine quickly gained popularity among other air-conditioning users across the country.
Through this pilot program, Qingdao Jinhua aimed to further expand the use of the Wenter refrigerant recovery machine within well-known enterprises that have high domestic credibility. This effort supports China’s atmospheric environment management and contributes to national environmental protection and energy conservation goals. By raising awareness among users, the company achieved rapid product promotion and created a win-win situation for all parties involved.
The Wenter refrigerant recovery machine generated a strong response during its one-month trial at Haier’s various maintenance outlets. Maintenance staff reported that the machine significantly reduces maintenance and production costs, saves money, and most importantly, benefits the environment.
According to feedback from Haier customers, before using the Wenter machine, refrigerants were typically released into the atmosphere during air conditioner maintenance. For example, R22 refrigerant, commonly used by Haier, costs about 20 yuan per kilogram. On average, around 40 kilograms of R22 is discharged during each maintenance, resulting in 800 yuan lost per session — equivalent to one worker’s monthly salary. With more than 10 small maintenance outlets in Qingdao and two maintenance sessions per day at each outlet, the daily loss amounts to 16,000 yuan. This sum could cover a worker’s annual salary in Qingdao. If all air conditioning repair shops nationwide failed to recycle refrigerants, the economic and environmental losses would be staggering.
It’s truly a waste! More importantly, it harms the environment and increases the burden on national environmental governance. Why aren’t these eco-friendly and energy-saving products being widely adopted?
Therefore, we can confidently say: “The Wenter refrigerant recovery machine is not only a gift for the country’s environmental protection efforts but also timely rain for air conditioning maintenance professionals.â€
