Fresh Air Ventilation Units and Industrial Air Coolers — Heat Exchangers for Fresh Air Systems, Air Conditioning, and Livestock Ventilation

Fresh air ventilation units and industrial air coolers play a key role in fresh air systems, air conditioning, and livestock ventilation by ensuring continuous air exchange, temperature control, and improved indoor air quality. By integrating efficient air-to-air heat exchangers, energy recovery between exhaust air and incoming fresh air can be achieved, significantly reducing overall system energy consumption.
In industrial and commercial air conditioning applications, the heat exchanger recovers sensible heat or cooling energy from exhaust air to preheat or pre-cool the incoming fresh air, thereby reducing the load on chillers or heating sources. In industrial air cooler and livestock ventilation systems, the heat exchanger helps maintain stable inlet air temperatures while ensuring adequate ventilation, improving animal comfort and lowering seasonal cooling and heating costs.
With a compact structure and stable operation, these heat exchangers are available in sensible or total heat recovery configurations to suit different operating conditions. They are widely used in factory fresh air supply, air conditioning make-up air, and livestock ventilation systems, providing an energy-efficient, reliable, and easy-to-maintain solution for modern air handling applications.

Energy-Saving Retrofit for Disc Dryers in Powder Drying — Hydrophilic Aluminum Foil Heat Recovery Core for Steam Exhaust White Plume Reduction

During powder drying processes using disc dryers, the exhaust steam is typically characterized by high temperature and high moisture content. Direct discharge leads to significant energy loss and often results in visible white plume emissions. By integrating a hydrophilic aluminum foil air-to-air heat recovery core, effective energy recovery and exhaust treatment can be achieved as part of an energy-saving system retrofit.
The heat recovery unit features aluminum foil plates with a hydrophilic coating, ensuring efficient condensate drainage during indirect air-to-air heat exchange. As the hot steam exhaust is cooled, sensible heat is recovered and reused to preheat incoming fresh or make-up air, while water vapor condenses and is removed, achieving simultaneous dehumidification and white plume reduction.
In disc dryer applications for chemical powders, food additives, mineral powders, and fine chemicals, this heat recovery core significantly reduces steam consumption, lowers the load on downstream exhaust treatment systems, and improves exhaust appearance and environmental performance, providing a stable and energy-efficient upgrade solution for powder drying operations.
