Condensate Mixers

Pick DSI Heater for Condensate

The natural benefits of the Pick Heater and it’s 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 to 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.


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.


Industries Include:


  • Refineries
  • Petro-Chemical Plants
  • Power Generation Plants

Why Choose a Pick Condensate Mixer?



Complete Mixing of Condensate Streams

With Direct Steam Injection, steam is instantly blended into the process fluid, resulting in 100% heat transfer with full use of both the latent and sensible heat. 

Eliminates Steam Hammer

The Pick System injects steam into the liquid through hundreds of small orifices in the injection tube. The unique spring-loaded piston rises or falls in response to changes in steam flow. This eliminates pressure equalization between steam and water pressures preventing steam hammer.

Compact Installation

With a Pick Heater there is no need for a flash tank and condensate return system.

How the Condensate Mixer Works:



  1. High Temperature Condensate enters
  2. Steam Trap
  3. Sub-cooled Condensate enters
  4. Mixed Condensate exits
