Oji Industrial Materials Management Co., Ltd. offers advanced Energy Recovery Ventilator (ERV) Cores, crucial components for high-performance ventilation systems in buildings and residences. These static-type cores, crafted from Oji's proprietary special paper, efficiently recover total heat (both temperature and humidity) from exhaust air, transferring it to incoming fresh air. This technical process significantly reduces the load on air conditioning, leading to substantial energy savings and improved indoor comfort. The ERV core's performance, particularly its heat exchange efficiency, is directly linked to the quality of its specialized paper material and optimized heat and moisture transfer capabilities. The market for these cores is expanding rapidly, driven by increasing demand for enhanced ventilation (e.g., for infection control), decarbonization initiatives, and government regulations and subsidies promoting energy-efficient housing. Oji manufactures these innovative ERV cores at its facilities in Nantong, China, and Kadoma, Japan.
