Proper Bending of Copper Tubes in Fintube Coils

Proper bending of copper tubes in finned-tube coils is one of the most important stages in manufacturing heat exchangers and heating or cooling systems. When this process is done correctly, the device works better, pressure drop is reduced, and the coil’s service life increases. In contrast, improper bending can cause tube flattening, cracking, reduced fluid flow, and even leakage. Copper tube is one of the best choices for fintube coils because it is flexible, has high thermal conductivity, and resists corrosion...

Compressor Service Valves: How the Three Positions Work

<p> A compressor service valve provides access to a refrigeration system for pressure measurement and certain service procedures. Service valves are commonly installed at the compressor’s suction or discharge connection. Moving the valve stem changes how the compressor, refrigerant line, and gauge port communicate. This article describes a common three-way compressor service valve. Valve designs differ, so check the instructions for the installed model before operating it.

Main parts of a service valve

A typical three-way service valve has three connections and an adjustable...

Compressor Overheating in refrigeration system: Causes and Troubleshooting

<p> Compressor overheating is a warning sign that a refrigeration system may be operating outside its intended conditions. Prolonged exposure to excessive heat can reduce oil viscosity and weaken lubrication. Depending on the compressor design and how long the problem continues, it may lead to component wear, oil breakdown, valve damage, or motor failure. The right response is to identify why the compressor is running hot. Cooling its exterior or changing a control setting without diagnosing the system may leave the underlying...
