Frequently Asked Questions (FAQ)
Q1: What is the primary function of a capillary tube distributor in an HVAC system?
A capillary tube distributor evenly divides the liquid or mixed-phase refrigerant coming out of the expansion device into multiple parallel circuits of the evaporator coil. This uniform distribution ensures that all parts of the coil achieve balanced heat transfer, maximizing overall cooling performance and preventing compressor slugging.
Q2: Can Ningbo FXT customize the number of outlets and tube lengths?
Yes, absolutely. As a dedicated HVAC/R components supplier, we specialize in custom manufacturing. We can configure the inlet/outlet diameters, the number of distributed circuits, capillary wall thicknesses (e.g., 1.5mm to 2.0mm), and exact capillary lengths according to your engineering drawings or Technical Purchase Specifications (TPS).
Q3: What quality testing do these refrigerant distributors undergo?
Every capillary distributor assembly undergoes strict structural and pneumatic inspection. We perform 100% airtightness testing and pressure resistance testing at designated factory limits to guarantee zero leakage and precise flow consistency before delivery to international markets.
Q4: Are your copper capillary distributors compatible with new low-GWP refrigerants?
Yes. All wetted materials (including the high-grade copper and brass alloys used in our assemblies) are fully tested and compatible with modern refrigerants such as R513A, R32, and R410A, as well as synthetic POE/PAG lubricating oils.
