Product Description
In the massive ventilation circuits of deep mines, exhaust air represents one of the largest and most untapped energy reservoirs. We designed the Ventilation Waste Heat Recovery Device to convert this constant-temperature exhaust into high-grade thermal assets. With nearly 30 years of manufacturing expertise, we have engineered this system to extract low-grade heat from mine exhaust (a source that stays stable at 15°C to 25°C year-round) and upgrade it using advanced heat pump technology. This is not a standard commercial unit; our device is a "mining-strengthened" system integrated with specialized self-cleaning heat exchangers that resist the high humidity and dust typical of mine return air. In flagship projects for national-level mining groups, this system achieved a COP of up to 5.0, providing ample wellhead anti-freeze and building warmth while slashing operating energy costs by over 70%.
We understand that for global procurement officers, reliability in harsh environments is the primary concern. Our recovery devices are manufactured using premium components in our 25,000 square meter high-tech factory and protected by our self-developed HyeScada monitoring software. This enables completely unattended operation, with the system dynamically adjusting heat output based on real-time ventilation data and ambient temperature. By replacing traditional coal-fired boilers with this zero-emission solution, we help mines meet strict "Green Mine" and "Dual Carbon" standards. With over 190 patents backing our designs, we provide heating infrastructure that is not only sustainable but highly profitable, typically paying for itself within two to three winters through energy savings alone.

Applications
Mainly used for recovering waste heat from the mine's primary return shafts to provide centralized heating for wellhead houses, office complexes, and worker dormitories. It is an ideal solution for coal and non-coal mines seeking to eliminate oil/coal-fired boilers and transition to a renewable energy model.
Customization & Manufacturing
Every ventilation waste heat recovery device is customized based on your site's specific exhaust parameters. Our Design Research Institute performs full thermodynamic modeling to ensure the heat pump cycle is perfectly tuned to your local humidity and dust levels. We utilize CNC precision machining and high-purity welding at our Wuxi base to ensure every module meets our 15-year industrial design life.
Service & Logistics
We ship recovery modules in reinforced international flat-rack containers. Our service package includes 7x24 hour remote technical support and on-site installation guidance. Through the Hongye Cloud platform, we provide proactive maintenance alerts and remote diagnostics, ensuring your energy recovery system maintains peak performance throughout its lifecycle.
FAQ
Q: How do you handle high dust in the return air?
A: We use wide-pitch fins and automatic high-pressure spray cleaning systems to prevent clogging and maintain heat exchange efficiency.
Q: Can it provide cooling in summer?
A: Yes, the system can be configured for reverse-cycle operation to provide chilled water for underground heat hazard control.
Q: Is it compatible with existing fans?
A: Yes, our CFD-optimized design keeps the air-side resistance below 150 Pa, ensuring zero negative impact on your main fans.
