A condensate pump is a device used in heating, ventilation, air conditioning (HVAC), and refrigeration systems to collect and remove the water (condensate) produced during the cooling or heating process. When gravity drainage is not possible—such as in basements or areas where the condensate cannot naturally flow to a drain—the pump collects the water in a small tank and automatically pumps it to a suitable drainage point once it reaches a certain level. It typically includes a float switch that activates the pump when needed and may also feature an alarm system in case of malfunction or overflow. Condensate pumps are essential in maintaining the efficiency and safety of HVAC systems, preventing water damage and ensuring proper operation.
