How can we increase the bathhouse’s profits?
Bathhouses are no longer allowed to use boilers; instead, they’ve switched to commercial hot water—meaning they now directly purchase hot water from external suppliers, which is delivered in tanks right to their doors. This approach is more convenient and safer for cleaning and maintenance. However, due to the higher cost of commercial hot water, bathhouses’ profits have declined compared to using boilers. Especially recently, the government has introduced several new policies aimed at environmental protection and energy conservation, one of which is the increase in water prices in Xinjiang. Under these circumstances, water conservation—particularly in the bathroom industry—has become an urgent necessity. The days when customers could casually let the water run freely for just a few yuan per bath are now firmly behind us. Induction showerhead Its use has made a significant contribution to water conservation. However, induction showers, lacking a mixing valve and relying on automatic water sensing, tend to produce fluctuating water temperatures during bathing—especially those using campus “one-card” systems. Induction showerhead When you swipe your card, water is dispensed—but the water temperature fluctuates unpredictably between hot and cold, making it difficult to control and posing a safety hazard.

What is...? Mixer ?
A mixing valve is a mechatronic device that uses a temperature sensor to detect water temperature, a microcomputer for control, and a solenoid valve for actuation, automatically adjusting the water temperature to reach the preset usage temperature.
? Mixer What is the scope of application?
The mixer is suitable for bathhouses (rooms) in government agencies, organizations, and public venues, as well as for industries such as chemical processing, dyeing, and printing that require constant-temperature water. With slight modifications, it can also be used in central air-conditioning systems—for example, to maintain a stable water temperature in cooling and heating systems. If equipped with a steam-water mixed intelligent mixer, you can eliminate the need for a hot-water storage tank, thereby saving space and reducing manufacturing costs.
? Mixer What are the advantages?
1. Smart mixer faucet. Automatically controls water temperature adjustment, making it convenient for water and energy conservation.
2. The mixer boasts high reliability, strong anti-interference capability, and a long service life.
3. The mixer offers a wide temperature control range and high temperature control accuracy.
4. The mixer has a compact size and is easy to install, reducing the cost of tank manufacturing and saving on raw materials and building space.
5. The mixer is easy to operate, simple to maintain, and can continuously supply water at a constant temperature.
6. The mixer features a digital display for intuitive and straightforward operation, as well as over- and under-temperature alarm functions.

♦ Chengde Longzhida Mixer Structural composition:
The HSZ series bath thermostatic mixing valves produced by Chengde Longzhida Company are electromechanical devices that employ microcomputer control technology and utilize advanced temperature sensors for feedback detection, thereby controlling solenoid valves to automatically adjust the outlet water temperature. The entire system consists of two main components: one is the intelligent control and electrical control section, and the other is the mechanical actuation section responsible for mixing the water.
♦ Chengde Longzhida Mixer Working principle:
(1) The electrical controller section consists of a DC regulated power supply, a microcontroller, a temperature sensor, control software, and other components. It is used to control the on-off operation of the solenoid valves of the mixing mechanism actuators, automatically regulating the actuator output to maintain a constant water flow rate, water temperature, and system performance according to different conditions.
(2) The actuator section of the Chengde Longzhida mixing device consists of components such as an electromagnetic valve assembly, a mixing bucket, and mixing blades. Under the control of the controller, this section achieves thorough mixing of cold and hot water. The mixing process leverages the pressure difference between cold and hot water to facilitate the introduction of cold water into the hot water stream. Furthermore, the mixing blades ensure that the cold and hot water are thoroughly blended, ultimately delivering constant-temperature hot water.
(3) The electrical controller of desktop mixing valves of the HSZ-50BP model and above is equipped with a frequency converter controller, which regulates the output pressure of the cold-water pump to ensure constant water pressure supply. At the same time, the electrical controller incorporates a pipeline return-water circulation system controller that automatically recirculates cold water from the pipes back into the water tank, thereby preventing wastage of water resources caused by the discharge of cold water from the pipes.

So, which places are using it? Chengde Longzhida Mixer Does it really work?

Tsinghua University has cherished our mixers for over two decades, day in and day out. Mixer It boasts a long service life because it features digital display. After setting the desired water temperature for the mixed output, the mixer automatically and fully integrates mechanical and electrical components to perform water mixing without any manual supervision. Thanks to technological innovation, advanced electronic devices such as temperature sensors and solenoid valves have been incorporated. The size, shape, distribution, and number of the mixing chamber and mixing blades—all critical components of the actuator—have undergone thousands upon thousands of rigorous experiments and quality checks. As a result, we’ve achieved a breakthrough: within just two minutes, the mixed water reaches the set temperature, and the constant-temperature output is maintained with an error margin of no more than 0.5 degrees Celsius. Additionally, the device is equipped with high-temperature and low-temperature alarm functions. To address the issue of fluctuating water pressure in large-capacity water supply systems, technicians from Chengde Longzhida have further installed a pressure-stabilizing device into their large-capacity mixers—mixers capable of delivering over 50 tons of water per hour. This ensures both constant temperature and constant pressure water supply, making these mixers a true boon for public bathhouses.
