What is a common sign that the shaft seal in a low-pressure system requires attention?

A common indication that the shaft seal in a low-pressure refrigeration system requires attention is the presence of oil leaks around the compressor. In refrigeration systems, when a seal is compromised, refrigerant can escape, leading to a reduction in system efficiency. This escape often takes the oil with it, resulting in visible oil leaks around the compressor area.

Oil is a crucial component in lubricating the moving parts within the compressor and maintaining overall system efficiency. When oil starts to leak due to a failing shaft seal, not only is there a potential loss of refrigerant leading to a drop in system performance, but the environment also faces potential contamination due to these leaks. Addressing this issue promptly helps ensure the longevity and effective operation of the refrigeration system while minimizing environmental impact.
