Breaking Free from Gravity’s Chains, Ushering in a New Era of Smart Drainage: Shanghai Ledo Vacuum Negative Pressure Drainage System
In the process of urban development, traditional gravity drainage systems are increasingly facing challenges: costly “invasive excavation” for retrofitting old urban areas, difficulty laying pipe networks in complex terrain, commercial space adjustments constrained by fixed pipelines, and growing demands for public health and water conservation… Are we destined to be confined by “gravity” and “slope”?
The answer is no. The Vacuum Drainage System Division of Shanghai Ledo Industrial Co., Ltd. , with its innovative “Vacuum Negative Pressure Drainage Technology” and leading “Smart IoT Platform,” provides you with a revolutionary drainage system solution covering both indoor and outdoor scenarios, redefining the rules of wastewater collection and conveyance.
I. Technological Innovation: Why Choose Vacuum Negative Pressure Drainage?
Vacuum drainage is a technology that creates negative pressure within pipes through a central pump station, using air pressure differential as power to convey wastewater. Compared to traditional gravity-dependent methods, it offers four disruptive advantages:
Extreme Water Savings: Core vacuum toilets use only 1.2 liters per flush (urinals only 0.6 liters), saving over 80% water compared to traditional products, directly responding to national water conservation strategies and significantly reducing operational costs.
Layout Freedom: Pipes require no slope—they can climb upward, extend horizontally, or even bypass obstacles, completely breaking free from gravity constraints. This provides unprecedented flexibility for building space layout, especially suitable for renovation projects and complex structures.
Cleanliness & Hygiene: The system operates fully sealed, completely eliminating wastewater leakage and odor emission. The powerful negative pressure flush effectively removes sediment and bacteria from pipes, fundamentally improving the environment of restrooms and pipe shafts.
Economical & Efficient: Smaller pipe diameters (typically DN50-80), shallower burial depths, significantly reduced earthwork, faster installation, and notably lower construction and maintenance costs throughout the lifecycle.
II. Full-Scenario Product Matrix: Providing Smart Answers for Every Drainage Need
We offer a complete product ecosystem from source to terminal, ensuring seamless system integration.
Outdoor Smart Collection: “Star Dome” Smart Negative Pressure Collection Well
Replacing traditional concrete manholes, this serves as the system’s “smart starting point.” Made of Carbon-Hydrogen HPC material with a 50-year lifespan; features pneumatic/electric dual-mode backup for operation even during power outages; each well has a unique ID, supporting remote monitoring and predictive maintenance.
Indoor Water-Saving Core: Vacuum Sanitaryware Series
Vacuum Toilet: 1.2L ultra-water-saving flush, ultra-quiet design, modern minimalist appearance—a “star product” enhancing project quality.
Vacuum Interface Valve: The system’s “flexible joint,” easily connecting any traditional drainage point like sinks or floor drains to the vacuum system. This is the key to achieving free space layout, especially suitable for renovation projects.
Special Scenario Tools: Dedicated Collection Devices
Vacuum Floor Drain: Perfectly solves drainage for bathrooms and showers.
Condensate Collection Box: Standard equipment for supermarket freezers and air conditioning drainage.
Vacuum Grease Interceptor: Specially designed for commercial kitchens, efficiently separating grease at the source, solving pipeline clogging pain points.
System Power Core: “Zhiqing” Series Vacuum Pump Stations
Offering a full range from compact unit stations (suitable for small commercial buildings), medium standard stations (for communities, hospitals), to large central stations (for airports, district development). All series feature modular design and built-in intelligent controllers, serving as the reliable “heart” of system operation.
III. Smart IoT: Empowering the Entire System for Worry-Free Operation
IoT technology is our core advantage, embedded in every product.
TianwuCloud Platform: Through PC or mobile app, achieve real-time monitoring, smart alerts, energy efficiency analysis, and report generation for global projects, making the drainage system transparent and controllable.
TianwuEdge Edge Computing Gateway: Ensures stable, intelligent local system operation even during network interruptions.
This smart system not only provides digital management tools for end customers but also offers our partners powerful remote operation and maintenance support capabilities, greatly enhancing service efficiency and customer loyalty.
IV. Mature Solutions: Addressing Industry Pain Points Head-On
We provide proven, mature packages tailored to specific needs across different industries:
Municipal & Public: Solving difficulties in retrofitting old residential areas, high costs of municipal excavation, and construction restrictions in environmentally protected zones.
Commercial Complexes: Addressing challenges of frequent business format adjustments, easy clogging in restaurant drainage, and high requirements for restroom environments.
Transportation Hubs: Meeting water and energy conservation needs under high passenger flow, along with demands for highly reliable operation and maintenance.
Healthcare: Aligning with strict hygiene requirements, special space layouts, and safety needs for radioactive wastewater collection.
