The problem: A piston-type reciprocating compressor has had valve damage, or the valves just are not sealing for some reason. This low-temperature refrigeration system has a thermostatic expansion ...

Installing a recycle valve in parallel with the antisurge valve of a turbine-driven multistage (low pressure/high pressure) centrifugal compressor, in combination with control system modifications, ...

Refrigeration control valves for industrial refrigeration systems have been an important system component since the 1920s. When a control valve fails, the result can be as significant as a more costly ...

Cold temperatures and water can lead to only one outcome – and ice has no place in a truck's air system. Frozen moisture can disable compressors, along with any of the multitude of air valves in the ...

Years ago, it was common for shops to have a central power source that drove all the tools through a system of belts, wheels and driveshafts. The power was routed around the work space by mechanical ...

Compressor surge occurs when flow is too low with respect to the change of pressure of the compressor or when ΔP is too high with respect to the flow. A decreasing flow coupled with an increasing ∆P, ...
