Shell and tube heat exchangers are essential for cooling nitrogen gas streams in industries such as food preservation, chemical processing, and electronics manufacturing. These exchangers feature a bundle of tubes where hot nitrogen gas flows through one path, and a cooling fluid through another, optimizing heat transfer. This design ensures precise temperature control, critical for maintaining process efficiency and protecting equipment in inert or high-temperature environments. Their durable construction supports high pressures and large volumes, while corrosion-resistant materials maintain nitrogen purity.
