Condensate Pump

Condensate Pumps

Trebles supplies condensate pumps for domestic, commercial and industrial applications. Alongside standard domestic condensate pumps for heating systems, we supply more specialist solutions for air conditioning, refrigeration, dehumidification and industrial applications where the liquid being handled may contain chemicals.

Condensate pumps are used to collect and remove liquid produced when water vapour condenses within heating, cooling and other equipment. In domestic applications, they are most commonly used with gas and oil condensing boilers where condensate needs to be discharged from the appliance to a suitable drainage point.

Commercial and industrial applications are more varied. Condensate pumps can be used with air conditioning and refrigeration systems, dehumidifiers, evaporators, heat exchangers and other equipment that produces condensate. In some industrial applications, the liquid being collected can contain chemicals, meaning the pump must be selected according to the properties of the fluid and the conditions in which it will operate.

Trebles can specify commercial and industrial condensate pumps based on the end-use application, taking into account factors such as the fluid being pumped, temperature, required flow, discharge head and installation environment.

How Do Condensate Pumps Work?

Most condensate pumps are designed to operate automatically and intermittently. Condensate collects in an integrated tank until it reaches a set level, at which point a float switch activates the pump. The pump then discharges the collected liquid before stopping when the level falls.

Some condensate pumps incorporate a two-stage switching system for additional protection. If the liquid continues to rise because the pump has failed or the discharge line is blocked, a second level can trigger an alarm or other safety response. This allows the system to operate automatically while providing additional protection against overflowing condensate.
