MK Thermostatic Steam Traps - Membrane Series

Effective condensate removal or air venting

The responsiveness of the balanced pressure membrane regulator is a distinguishing feature of the MK thermostatic steam traps in the membrane series. This makes it suitable for heat exchangers where efficient operation is not adversely affected by minimal condensate build-up. Most heat exchangers are oversized and can make efficient use of not only the latent heat present in steam, but also the sensible heat present in condensate.

MK thermostatic steam traps can be effectively used as steam distribution drip traps, steam tracing applications and a myriad of other applications where they contribute to proper and energy efficient system operation.
