The Siebe H18-301 Invensys H18301 box is a crucial component in refrigeration and air conditioning systems designed for industrial and commercial applications. This high-performance desiccant dryer is manufactured by Invensys, a globally recognized leader in the field of industrial automation and process control.
The H18-301 desiccant dryer is a horizontal, single-pass, regenerative model that is designed to remove moisture from compressed air or process gases. It is ideal for applications where the intake air or process gases contain high levels of moisture, which can cause equipment failure, product contamination, or reduced efficiency.
The dryer measures 45.7 inches in length, 26.8 inches in width, and 31.5 inches in height. It is constructed from high-quality materials, including a 316L stainless steel shell and 304L stainless steel internal components, ensuring durability and resistance to corrosion in harsh environments.
The desiccant used in the H18-301 dryer is a desiccant bead material, which is highly effective at absorbing moisture. The dryer operates on a regenerative cycle, which means that it alternates between a desorption cycle, where the desiccant beads are heated to release the absorbed moisture, and a sorption cycle, where the dry, cool air passes through the desiccant bed to absorb moisture.
The H18-301 dryer is equipped with a number of features to ensure optimal performance and ease of maintenance. These include a temperature control system to regulate the desorption temperature, a pressure switch to indicate when the desiccant needs to be regenerated, and a sight glass to allow for easy monitoring of the desiccant bed level.
The dryer also comes with a number of optional accessories, including a pressure relief valve, a temperature control valve, and a purge fan kit, which can be added to meet specific application requirements.
Overall, the Siebe H18-301 Invensys H18301 box is an essential piece of equipment for any industrial or commercial operation that requires moisture-free air or process gases. Its high-performance design, durable construction, and ease of maintenance make it a reliable and cost-effective solution for a wide range of applications.
