Product Description
Coal mine production sewage typically contains vast amounts of stable thermal energy, but its high suspended solids and mineral content make heat extraction difficult. We developed the Coal Mine Sewage Source Heat Pump specifically to handle these "dirty water" conditions. The core of this system is our self-developed anti-clogging and automatic online cleaning heat exchanger technology. By extracting heat from sewage at 10°C - 25°C, we can provide high-grade hot water at 45°C - 55°C with a COP of 3.5 to 5.0. This allows mine operators to provide continuous heating for living areas while complying with environmental "Dual Carbon" strategies by utilizing previously wasted resources.
Wuxi Hongye firmly believes that green mining should not come at the cost of high operating expenses. Our system is designed as a "fit and forget" solution. It integrates our HyeScada monitoring software, which automatically adjusts heat pump output based on building demand and sewage inlet temperature. In flagship projects for national-level mining groups, this system has completely replaced coal-fired boilers, reducing operating energy costs by over 60%. For international partners, this system provides a robust, high-performance solution that has been field-tested for decades in China's most challenging mining environments, ensuring reliability where commercial-grade units fail.

Applications
Mainly used for centralized heating and domestic hot water in mine dormitories, bathhouse facilities, and office buildings. It is also an excellent solution for preheating industrial process water or providing winter heating for sewage treatment facilities within industrial mining zones.
Expertise & Quality Control
Every system is manufactured in our ISO 9001:2015 certified factory. We utilize fiber laser welding and CNC precision machining to ensure the structural integrity of high-pressure refrigerant circuits. Our quality management team performs 100% full-load testing and rigorous pressure retention tests on each unit to guarantee leak-free operation for at least a 15-year lifecycle.
Packaging & Logistics
The heat pump units are shipped as compact skid-mounted modules inside reinforced export-standard plywood cases. We handle all international shipping documentation and support EXW, FOB, and DDP terms. For large projects, we provide on-site installation guidance to ensure the system integrates correctly with your local sewage collection and building distribution networks.
FAQ
Q: How does the system prevent clogging?
A: We use specialized "wide-channel" heat exchanger designs combined with automatic high-pressure backwash systems that keep surfaces clean without manual intervention.
Q: Is it noisy?
A: No, our industrial screw compressors are mounted in sound-dampened enclosures, keeping noise levels below 75dB.
Q: Can it handle acidic sewage?
A: Yes, we can customize heat exchanger materials to 316L stainless steel or titanium alloy for highly corrosive water qualities.
