A Sensible Heat Recovery Exchanger is an energy-efficient device designed for air-to-air heat exchange, recovering only sensible heat based on temperature difference, without any moisture or humidity transfer. It is widely used in ventilation systems, industrial exhaust air treatment, drying processes, and fresh air applications, providing effective energy recovery while maintaining complete air separation.
Sensible heat recovery exchanger
Working Principle
The exchanger utilizes a metallic or composite heat exchange core that allows high-temperature exhaust air and low-temperature fresh air to flow through separate channels. Heat is transferred through the heat exchange surfaces without air mixing, preheating or precooling the incoming air and significantly reducing heating or cooling loads.
Key Features
Sensible heat recovery only, no moisture transfer
Complete separation of air streams, no cross-contamination
High heat transfer efficiency and stable performance
Compact structure, easy system integration
Suitable for high-temperature, high-humidity, and corrosive air conditions
Materials and Structure
The heat exchange core can be manufactured from aluminum foil, stainless steel foil, or other corrosion-resistant materials. Structural configurations include cross-flow, counter-flow, or multi-pass designs, tailored to specific application requirements.
Typical Applications
Industrial fresh air and exhaust ventilation systems
Waste heat recovery from drying equipment exhaust
Spray coating, textile, and chemical process exhaust air
Energy storage cabinets and equipment cooling systems
Agricultural, livestock, and mushroom growing ventilation systems
Benefits
Reduced energy consumption
Lower operating costs
Improved system thermal efficiency
Enhanced indoor air quality
Support for energy-saving and sustainable operations

Equipment: BXB600-595-4-H Air-to-Air Plate Heat Exchanger
Working Conditions: 4500 m³/h airflow per unit; exhaust temperature 50–60°C; contains ammonia, moisture, and corrosive components
Application Background
During livestock manure fermentation, large volumes of warm and humid exhaust air containing ammonia are continuously discharged. A significant amount of heat is lost during this process. By using an air-to-air heat recovery exchanger to preheat fresh air, the system can reduce energy consumption for heating, improve ventilation efficiency, and decrease visible white plume from exhaust discharge.
Heat Exchanger Selection
The BXB600-595-4-H is a cross-flow aluminum plate heat exchanger, suitable for fermentation exhaust, composting exhaust, and other moderate-corrosive gas conditions.
• High efficiency: Cross-flow structure with strong temperature difference driving force; sensible heat recovery efficiency can reach 50–65%.
• Low pressure drop: Optimized flow channels, well-matched with the 4500 m³/h airflow requirement.
• Corrosion resistance: Optional surface passivation or epoxy coating for enhanced protection against ammonia and acidic condensate.
• Zero energy consumption: No water or steam required; heat recovery is achieved solely through the temperature difference between exhaust and fresh air.
Functional Benefits and Energy Savings
-
Fresh Air Preheating
Exhaust air at 50–60°C can effectively preheat cold fresh air during winter, reducing the heating load for livestock houses, composting systems, and fermentation equipment. -
Reduced Exhaust Humidity and White Plume
After heat extraction, the exhaust temperature drops, reducing visible white vapor during outdoor discharge and improving environmental perception. -
Lower Corrosion Risks
Exhaust and fresh air remain completely separated. Tail gas channels can be coated for extended service life when handling corrosive components. -
Energy Savings
Compared with electric heaters or steam heating, the system can reduce energy consumption by 20–60%, depending on temperature conditions and fresh air load.
Installation & Maintenance Notes
• Install filters on the exhaust side to block dust and particulates.
• Ensure proper condensate drainage to prevent corrosion from acidic liquids.
• Select fans with sufficient static pressure to maintain airflow under varying humidity.
• Optional bypass system to stabilize fresh-air temperature during exhaust fluctuations.
The mine exhaust waste heat recovery system captures heat from mine ventilation exhausts to provide heating for surface facilities or pre-warm incoming air.
Benefits
-
Energy Recovery: Recovers up to 60% of waste heat from exhausts.
-
Cost Efficiency: Reduces heating costs in cold climates.
-
Safety: Improves working conditions by managing underground heat.
Implementation
In a mining operation, exhaust air from deep shafts is passed through heat recovery units to warm surface buildings, enhancing energy use in remote locations.
Case Study
A mine in a cold region reduced heating costs by 25% using this system, improving operational sustainability.
