Capillary tube for refrigeration and air conditioning
At Bundy Refrigeration, we understand the critical role that capillary tubes play in the efficient operation of refrigeration and air conditioning systems. We offer a range of high-quality capillary tubes, designed to meet the specific needs of these applications.
What are capillary tubes?
Capillary tubes are made of copper and serve as a throttling device in refrigeration and air conditioning systems. They are used to lower the temperature of the refrigerant before it enters the evaporator. The capillary tube’s length and diameter are crucial factors in determining the rate of refrigerant flow, and thus the cooling capacity of the system. Capillary tubes offer cost-effective solutions for small-scale refrigeration systems due to their straightforward design and manufacturing process.
Why choose Bundy Refrigeration capillary tubes?
Bundy Refrigeration produces its capillary tubes within applicable standards, ensuring their quality and reliability. Our copper capillary tube comes in different dimensions, and we also provide manufacturing made to order to meet your specific requirements.
Bundy Refrigeration’s capillary tube dimensions
Capillary tube dimensions, including length, inner diameter, and thickness, should be carefully selected to suit the specific requirements of the heat transfer and refrigeration system. The tube’s length determines the distance over which the refrigerant can expand and transfer heat, while the inner diameter and thickness influence the flow rate and pressure drop characteristics. These parameters are meticulously calculated during the design phase to achieve optimal performance and efficiency. Bundy Refrigeration produces capillary tubes and copper parts in a variety of sizes to suit different applications. Below are the dimensions of our standard offerings:
