After power failure, the system ensures humidity rise inside the cabinet remains below 10% (within 24 hours).10. High-quality, fast, and stable dehumidification capability with excellent sealing performance keeps internal humidity unaffected by external conditions.11. Dehumidifier/humidifier core requirements: Uses high-efficiency dehumidifier core with PPS + Class A flame-retardant housing, moisture resistance up to 300°C to prevent melting from sudden current surges. Solid polymer electrolyte membrane for moisture absorption must be imported (no replacement needed for 8 years), capable of directly electrolyzing and continuously removing moisture from the air, releasing it as gas externally, reusable and recyclable. The core must feature fast dehumidification, ultra-quiet operation, low power consumption, and no consumables. Key components of the dehumidifier core must come from internationally renowned companies.12. Fault indication requirements: High-brightness LCD display for temperature and humidity, 24/7 monitoring of dehumidifier core operation. Humidity settings via surface buttons on the LCD screen, simple and easy to operate. Temperature display range: 1-99°C, humidity display range: 1-99% RH. The LCD panel includes fault indication functionality. Through programmed settings, the working status of the dehumidifier core can be clearly monitored. If a fault occurs, the faulty part can be quickly identified for prompt repair.13. Power-off protection requirements: After power failure, the system uses "chemical moisture absorption compensation" to absorb moisture, ensuring humidity rise inside the cabinet remains below 10% RH within 24 hours. After power restoration, humidity settings do not need resetting; the system has memory functionality.【Dehumidification Principle】When the drawer-type high-efficiency intelligent water-free constant humidity preservation cabinet (mobile water-free constant humidity cabinet) is powered on, the dehumidifier core regenerates. The inner door closes while the outer door opens, allowing the drying material to regenerate and expel moisture, evaporating water vapor outside the cabinet. After regeneration, the outer door closes and the inner door opens. The drying material dehumidifies the interior, adsorbing moisture inside the cabinet to reduce humidity. The regeneration and dehumidification steps cycle under the control panel’s management, effectively regulating the cabinet’s humidity. more>

According to a report from the Municipal Urban-Rural Development Commission yesterday, the "hollow floor slab" technology, currently used in some public and large-scale buildings in the city, will be promoted in residential buildings this year. This technology can increase room clear height, reduce the number of load-bearing walls, and allow homeowners to freely design and modify the internal layout of their rooms. Experts explain that in traditional construction, the presence of numerous primary and secondary beams limits the clear height of buildings. Additionally, load-bearing walls in residences are constructed below these beams, resulting in uniform room divisions that restrict homeowners and designers from fully realizing their ideas during renovation. Arbitrarily removing load-bearing walls during decoration can also jeopardize the structural safety of the building. more>

Company: 陕西坤威电器有限公司

Product Description:        The fan control box, also known as the smoke control fan control box, is primarily used to control the start and stop of the fan. It can be operated manually or automatically from the control room, as well as via on-site buttons, and provides feedback on the equipment's operational status through the smoke control intelligent control screen. During normal ventilation, the fan control box can operate at low speed, starting the fan locally, or the high-speed button can be activated to run the fan at high speed. In automatic mode, it receives signals from the fire alarm center, switching the fan from low-speed to high-speed operation. If the fan needs to be stopped, it can be directly shut down at high speed from the fire control center, with the signal simultaneously returned to the fire control center. Normally, the low-speed setting is connected to the intelligent control system, serving as an exhaust fan, while the high-speed setting is linked to the fire control system (DC24V fire control interface). In the event of a fire, it receives control signals from the fire control system to activate high-speed operation, automatically cutting off the low-speed control circuit to achieve rapid smoke exhaust and ventilation.What are the features of the fan control box: 1. Equipped with a fire damper control interface, it can cut off power to the fire fan based on environmental requirements to prevent the spread of fire due to electrical issues; 2. Available in single-power and dual-power supply configurations; 3. Offers convenient installation methods: wall-mounted and floor-standing, among others; 4.
