Which option describes the function of the equipment that removes non-condensables from the condenser?

• A. Increase Condenser Cooling Water Flow
• B. Remove Non Condensables from the Condenser
• C. Filter Refrigerant
• D. Lower Condenser Pressure

Answer: (B)

Non-condensables in a condenser, like air or other gases, don’t condense and tend to collect at the top, forming a gas layer that insulates the condensing surface and reduces heat transfer. The equipment in question is designed to remove these gases from the condenser, purge them out, and keep the condenser operating at its intended efficiency and pressure. That’s why this option best describes its function: to remove non-condensables from the condenser. The other choices describe actions that don’t address purging non-condensables—boosting cooling water flow helps heat rejection but not gas removal, filtering refrigerant targets contaminants in the refrigerant rather than non-condensables, and lowering condenser pressure is a condition change, not a removal action.
