					          Process Steam Injection Liquid Heating Systems

                                    Pick Direct Steam Injection Systems heat any water-miscible liquid or
                                    aqueous slurry instantly on a continuous straight-through basis. Plus, they
                                    hold the outflow temperature to extremely close tolerances, regardless of
                                    fluctuations in steam, water pressures and outflow demand.
The Pick system injects into the liquid through hundreds of small orifices for instant and uniform blending.
A unique spring-loaded piston maintains steam pressure in excess of water pressure to eliminate steam/water
hammer.
Pick heaters cut fuel costs as much as 28 percent compared to indirect shell-and-tube or plate heat exchangers
because 100 percent of the heat energy in the steam is absorbed by the liquid. There is no condensate to be
vented, wasted or reheated. And with no condensate return, there is no need for high maintenance steam traps.
