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 the years, the company has continuously improved its technology, and the performance of its products now matches international standards. The quality of the company is consistently excellent, and its after-sales service system has earned a strong reputation among both domestic and international clients. As a result of its innovative product, the company has received several prestigious honors, including "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."
In November 2005, Qingdao Jinhua Refrigeration Technology decided to collaborate with well-known companies in Qingdao, launching a one-month free trial of the "Wenter Refrigerant Recycling Machine" at Qingdao Haier Industry and Trade Commercial Air Conditioning Co., Ltd., a globally recognized air-conditioning manufacturer. This initiative, themed “Care for Life, Protect the Blue Sky,†was carried out at Haier’s commercial air-conditioning maintenance outlets. 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-efficient new product. Through Haier's high credibility, the product quickly gained attention and spread to other air-conditioning users across the country.
This pilot activity sparked interest in further expanding the use of the Wenter refrigerant recovery machine within well-known enterprises that have high credit ratings nationwide. By doing so, the company aims to contribute to China’s atmospheric environmental management and support national efforts in environmental protection and energy conservation. As a result, more users have come to recognize the product, achieving rapid market promotion and creating a win-win situation for all parties involved.
The Wenter refrigerant recovery machine generated significant interest during the 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, supports environmental protection.
Here is a detailed account from Haier customers who used the Wenter refrigerant recovery machine: Before using the machine, refrigerants were typically released into the atmosphere during air conditioner maintenance. For example, with R22 refrigerant, which costs about 20 yuan per kilogram, each maintenance session would discharge around 40 kilograms, resulting in 800 yuan lost per session — equivalent to one worker’s monthly salary. With over 10 small outlets in Qingdao and two maintenance sessions per day at each outlet, approximately 16,000 yuan is wasted daily. That amount could pay for a worker’s annual salary based on Qingdao’s average wage. If all air conditioning repair shops across the country continued this wasteful practice, the environmental and financial losses would be staggering. It’s truly a pity!
More importantly, such practices harm the environment and increase 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 governance but also a timely rain for air conditioning maintenance users.â€
