🔍 Key Concepts

• Capillary tube systems usually have a fixed, very small bore metering device and are common on small, hermetic units (like household or small commercial refrigerators). • Larger systems with thermal expansion valves (TXVs) or multiple circuits often use larger, replaceable‑core filter‑driers with bolted covers or flanges for service. • The physical size and connection type of the filter‑drier should roughly match the refrigerant line size and capacity of the system.

💭 Think About

• Compare the relative size and construction of each dehydrator in the illustration to the kind of piping and capacity you would expect on a small capillary‑tube system. • Ask yourself which unit looks like a factory‑sealed, non‑serviceable liquid‑line drier typically installed once in small equipment, versus which ones look built for easy opening and core replacement. • Think about where the filter‑drier is installed in relation to the capillary tube—what shape and connection style makes sense to fit directly ahead of a tiny metering tube?

✅ Before You Answer

• Verify which option appears to be for a large, field‑serviceable system (flanged, bolted construction) and eliminate it for a simple capillary‑tube system. • Check which options have small line connections and compact bodies that would match small‑diameter liquid lines used before a capillary tube. • Confirm that your choice looks like a sealed, throw‑away liquid‑line drier, not a large replaceable‑core shell meant for big plants.
