Pick DSI Heater for Condensate

What is a Pick "Condensate Mixer"?

The natural benefits of the Pick Heater and its unique injection tube design provide an effective way of blending condensate streams smoothly. 


Formation of two phase flow on discharge side of steam traps creates pockets of flash steam that can collapse and cause damaging vibration and steam hammer in the return header.  The problem is most severe when mixing condensate streams with wide variance in pressure and temperature.  An example of this is discharge of high temperature condensate into a header containing sub-cooled condensate at lower pressure – a common situation at refineries and related industries.


Industries Include:


  • Refineries
  • Petro-Chemical Plants
  • Power Generation Plants

Why Choose a Pick Condensate Mixer?


Eliminates steam hammer and pipe damage when mixing condensate streams at different pressure and temperature. High temperature condensate forms a two-phase mixture with drop in pressure as it is discharged from the trap. This stream is dispersed through numerous small orifices into sub-cooled condensate, flowing through the main housing of the mixer. This promotes immediate absorption, thus preventing formation and collapse of large steam bubbles to eliminate hammer.

How the Condensate Mixer Works:


A Pick Heater provides an effective method of condensate mixing.  Sub-cooled condensate flows unobstructed through the main housing.  Discharge from the high pressure trap is dispersed into the sub-cooled condensate through the multiple orifice injection tube.  This breaks the two phase flow into fine streams to promote immediate condensation of flash steam, thus eliminating vibration and steam hammer.  Pressure and temperature balance are such that flash steam is fully condensed, resulting in discharge of 100% liquid at outlet of the mixer.
