Condensate lifters

What is a condensate lifter?

Condensate systems should in principle always be designed to be downward flowing. However, this is not always possible, and during condensate removal the condensate must sometimes be lifted upward. A rising condensate line is not inherently a problem as long as the line has sufficient pressure to overcome the condensate system pressure combined with hydrostatic back pressure. Problems typically arise in situations where the system’s inlet pressure drops, for example, when a control valve closes. In such cases, the pipeline remains waterlogged, inevitably leading to water hammer in the system. As its name implies, the condensate lifter helps to lift condensate in rising condensate lines.

Choosing the condensate lifter

We help you choose the appropriate model based on application and capacity.

GESTRA offers several solutions for lifting condensate, and the choice among them is based, among other factors, on the amount of condensate as well as the desired lifting height.

If the amount of condensate and lifting height are relatively small, excellent alternatives are the self-priming ED condensate lifter or the compact steam-assisted condensate lifter combination UNA 25-PS. Alternatively, a condensate removal/condensate lifter combination UNA 25-PK could be used, in which case a separate condensate remover is not required.

When the amount of condensate is larger, we recommend the steam-assisted self-priming FPS or KH condensate lifter. The FPS condensate lifter operates based on buoyancy technology and is also suitable for Atex areas. In contrast, the KH operates based on sensor technology and its capacity is essentially unlimited.
