This Raypak component is a high-quality, durable unit designed to transfer heat between two or more fluids. The device is constructed from copper and bronze for optimal thermal conductivity and corrosion resistance. It operates by allowing hot fluid to flow through tubes, which are surrounded by a second fluid that absorbs the heat. This process is facilitated by a large surface area provided by the tube walls, enabling efficient heat transfer. The unit is suitable for use in various applications including heating systems, power plants, and refrigeration units. It's designed to withstand high temperatures and pressures, ensuring reliable performance under demanding conditions.
