When installed on the liquid line, filter dryers allow the refrigerant liquid in systems to be dehumidified and deacidified. Among contaminating agents that can cause serious damages to compressor refrigerating systems, moisture plays a major role. Water solubility in refrigerants in the liquid phase is quite low, especially at low temperatures. Consequently, when water in the system exceeds the very low limits of solubility allowed at low temperature, the excess water turns into ice, and partially or totally blocks thermostatic expansion valves and capillaries. Therefore, it is absolutely necessary to equip refrigeration systems with an effective filter dryer on the liquid line.
Furthermore, Castel filter dryers are compact and strong, resistant to impact and abrasion. As a result, the fluid encounters constant, linear resistance in all points throughout, ensuring efficient dehydration and minimizing the pressure drop. Additionally, the dryer selection must be performed based on the refrigeration potential.
Castel offers different types of filter dryers, including hermetic models, models with moisture indicators, dual flow, and replaceable solid cartridges.
