Next-generation mixing valve

Next-generation mixing valve

The new-generation mixing valve—the pressure-difference-free intelligent mixing valve—is the company’s fifth-generation product, developed with independent intellectual property rights. It addresses the longstanding on-site challenge that cold-water pressure must exceed hot-water pressure by 1 to 1.5 kilograms, while also resolving the issue of uncontrolled hot water flow.


Use and Maintenance of Biomass Stove Appliances

Use and Maintenance of Biomass Stove Appliances

Biomass stoves are new-energy, energy-saving, and environmentally friendly products. During the combustion process for heating, they do not emit excessive carbon dioxide. They are non-toxic and dust-free. These stoves have a long burn time, and both national and local governments are stepping up efforts to promote their use. Below, we’ll introduce how to use and maintain biomass stoves.


Industry Applications and Positive User Feedback

Industry Applications and Positive User Feedback

Chengde Longzhida Intelligent Instruments and Meters Technology Co., Ltd. (formerly Xinlong Electronics) was one of the 14 key enterprises in Hebei Province’s electronic systems, designated as a specialized manufacturer by the former Ministry of Electronic Industry. Thanks to its high technological content, simple and convenient operation, reliable performance, and remarkable energy- and water-saving effects, it has earned widespread acclaim from hundreds of schools and thousands of users across China.


The working principle of biomass stoves

The working principle of biomass stoves

Biomass pellet stoves can be used for winter heating, grilling meat, and other purposes. Compared to conventional stoves, they are more energy-efficient and environmentally friendly—combustion produces no harmful gases that pollute the air or cause environmental damage. Thanks to the use of new-energy fuels, these stoves achieve higher and more complete combustion efficiency. Below, we’ll introduce how they work.
