Product Description
A significant portion of the electricity consumed by air compressors is wasted as heat-up to 85% of energy is lost simply by venting into the atmosphere. Our Compressed Air Waste Heat Recovery Device captures this thermal energy to provide a free source of high-quality hot water for your mining district. By installing our specialized heat exchangers in the air compressor's oil cooling circuit, we can extract thermal energy at temperatures up to 75°C, perfect for employee bathing, boiler feedwater preheating, or building heating. The beauty of the compressed air recovery equipment is that it provides this thermal energy at zero additional fuel cost. In fact, by assisting the cooling process, our system often helps air compressors run cooler, lowering their failure rate and extending their service life.
With 30 years in industrial automation, we have designed the mine compressed air recovery equipment to be extremely safe and non-intrusive. Our "dual circuit" isolation logic ensures that the air compressor's oil and your hot water never mix, preventing any cross-contamination. The system is managed by an automatic PLC that prioritizes the air compressor's safety; if hot water reaches the setpoint, bypass valves automatically divert oil back to the original cooling system. For international facility managers, this system is a "must-have" energy-saving tool. It is compact, skid-mounted, and can be integrated into any screw air compressor room in 1-2 days. By turning a waste stream into free hot water, you are not just saving money but directly contributing to your facility's ESG goals.

Applications
Widely used in mines, petrochemical, and manufacturing plants with large screw air compressors. The recovered heat is primarily used for worker bathing, laundry facilities, administrative building heating, and industrial cleaning processes.
Customization & Manufacturing
As an authorized integrator for Schneider and ABB, we use the highest quality control components in our recovery units. Every heat exchanger is manufactured using CNC precision machinery and pressure tested at our 25,000 square meter base. We can customize unit sizes and oil pipe interfaces (DN25 to DN50) to match any air compressor brand, including Atlas Copco, Ingersoll Rand, and Sullair.
Logistics & Shipping
Systems are delivered as compact skid-mounted units in reinforced export wooden cases, ready for "plug-and-play" installation. We provide all necessary connectors and detailed installation schematics. Our technical support is available 7x24, and our Hongye Cloud platform allows for remote performance tracking to ensure you achieve maximum waste heat recovery.
FAQ
Q: Will it void my air compressor's warranty?
A: No, our system is an external auxiliary cooling loop that does not modify the internal compression cycle.
Q: How long to recover the cost?
A: By eliminating fuel costs for water heating, most customers see a full return on investment in less than 12 months.
Q: Can it be used for oil-free compressors?
A: We offer dedicated air-to-water recovery systems specifically designed for the exhaust of oil-free compressors.
