Chengde Longzhida is a mixer manufacturer based in Hebei Province. The mixers it produces are specially designed for use in bathwater mixing. These mixers offer temperature control accuracy of 0.5 degrees Celsius and consume very little electricity. They do not have a built-in water-heating function and thus require a separate boiler to heat the water. Among all mixer products manufactured by Hebei mixer manufacturers, Chengde Longzhida mixers boast the highest temperature-control accuracy. Moreover, they are designed with energy-saving features in mind. Below are the specifications for the Chengde Longzhida HSZ-30A smart mixer: Dimensions: 890mm × 400mm × 980mm Hourly water output: 30 tons/hour Power supply voltage: 220V (380V for models after 50A) Inlet water temperature: ≤75°C Outlet water temperature:

The working principle of a smart mixing faucet.
The working principle of a smart mixing faucet.
The working principle of the smart mixing valve—by “smart mixing valve” I’m referring to the type used in public bathhouses for blending hot and cold water, not the kind used for building-level heating systems. This smart mixing valve has a wide range of applications: it’s suitable not only for bathhouses in government agencies, organizations, enterprises, and public venues, but also for industries such as chemical processing and textile dyeing that require constant-temperature water. With slight modifications, it can even be adapted for use in central air-conditioning systems, including cooling and heating systems, where precise temperature control is essential. The reason it’s called a “smart” mixing valve is that it’s a mechatronic device with digital display, operating via electromagnetic induction. It requires absolutely no manual supervision or manual water mixing.
A Complete Guide to Automatic Thermostatic Mixing Valves for Hot and Cold Water—Part 2: In the previous installment, we covered the complete lineup and pricing of automatic thermostatic mixing valves for hot and cold water (Part 1). In this installment, I’ll provide the remaining models and pricing for the automatic thermostatic mixing valves specifically designed for large-scale bathhouses by Chengde Longzhida. These automatic thermostatic mixing valves are auxiliary equipment developed for solar water heating systems and centralized hot water supply systems. Users can independently adjust the desired mixing temperature according to their actual needs; the required temperature can be quickly reached and stabilized, ensuring a consistently constant water temperature. This effectively eliminates the hassle of manual adjustments during bathing, which often lead to wasteful energy consumption and fluctuating water temperatures, thus truly achieving energy savings, water conservation, and enhanced safety and comfort.
