Ruian ChangSheng (RCS) Electric Appliance Co., Ltd.

Ruian ChangSheng (RCS) Electric Appliance Co., Ltd. established in 2002, located in Tangxia, Ruian, the capital of auto parts of China. Our factory covers a total area of 5,000 square meters. We specialize in the research & development, production, sales and service of Nitrogen Oxide NOx sensors. More than 300 kinds of NOx sensors are developed, which fit on all diesel vehicles (trucks and passenger cars). We have state-of-the-art automated machines and more than 50 trained staff, no fewer than 10 technicians.

Our NOx Sensors

Our NOx sensors are using imported Ceramic Chips, which are from HTCC Technology, it brings A cost-effective Balance between emission control and Urea consumption, the Corrosion Resistance Probe Provides the stable performance, our Excellent ECU Circuit (PCB) are Supported by Lab of University, which is upgraded fast. So we are confident to offer 2 years warranty.

Our NOx Sensors

Our NOx sensors have passed full testing cycle and criteria with global standard, and meet global emission standards (e.g. EPA 2013/ 2017/ 2021/ 2023, Euro 4/5/6. etc), and are 100% compatible with the original OE products manufactured by Continental/Bosch. Our products can provide end customer with a cost-effective service/repair option, compared to either high cost OE or low quality replacement products.


What We Have

As national high-tech enterprise, based on the independent research and development of nitrogen oxides and other materials, we take the know-how of high temperature ceramic chips and the core process of tape casting as our core competitiveness, and aim to break the monopoly in this field.
We persist in innovation, introduce advanced equipment, establish automated production lines and achieve factory intelligence, standardized production. We also actively establish scientific research cooperation with universities, devoting to new product development and providing technical support for products.

We mainly export to Canada, USA, Brazil, EU and Russia etc. We are expanding our business rapidly. Looking forward to establishing a long-term business relationship with you.
