The PickHeater adapts quickly to load changes and maintains precisetemperature control to within 1 C or less in many OPERATING RANGENo other steam injection system can match our turndownratio 12:1 with a single control valve, better than 100:1 with multiple steam control STEAM HAMMERU nique variable orifice injector automatically maintains aminimum differential between the steam and water eliminates harmful vibration and steam hammer.

2 LOW NOISE LEVELThe pick Heater operates at a low noise level, normally below85 dba, far superior to venturi-type LIQUID PRESSURE DROPP ressure drop does not exceed 2 PSI under normal flow MIXING IN HEATER BODYE liminates need for straight run discharge piping after theheater required by venturi-type Heaters deliver an unlimited supply of hot water ondemand, thus eliminating the need for large storage DESIGNWhen compared to conventional heat exchangers, PickHeaters take up only a fraction of the It Direct Steam Injection (DSI) Systems can be used to heat any water miscible liquid or aqueous slurryinstantly on a continuous straight-through basis.

3 The pick system injects steam into the liquid through hundreds of small orifices in the injection tube. Fine bubbles of steam are instantly absorbed by the liquid, resulting in 100% transfer of heat energy. A unique spring-loaded piston rises or falls, as more or less steam is required. This prevents pressure equalization between steam and water pressure, thuseliminating steam hammer. Helical flights in the chamber promote thorough mixing prior to heart of the pick Heater is the steaminjection tube and the spring-loaded piston. They serve three critical functions: Breaks steam into small streams.

4 Piston modulates in response to changes in steam demand to maintain a differen-tial between steam and water pressure. Piston closes during shutdown to prevent sudden collapse of steam inside the obvious advantages along with proven, dependable performance have made pick DSI the process heating method of choice where accurate temperature control, rapid response and energy efficiency are important 4/11/06 7:31 AM Page 5 Applications Retorts Sterilization CIP Pasteurizers Jacketed Kettles Tank Filling Extruders Reactor Vessels Centrifuge or Filter Back Flush Tank Car Heating/Washing Slurries Liquid-to-Liquid Mixing Condensate Mixing Green Liquor Heating Felt Washing Tempered Water Boiler Feed Water Parts Washer Bio Kill Starch Cooking23145 CONSTANT FLOWH eater Model 6X25-3 6X50-3 6X75-3 6X100-3 6X150-3 6X200-3 6X350-3 6X500-3 Steam Flow Lb/hr7001,2502,5005,0007,50010,00015,000 20,00035,00050,000 CapacityKg/hr3205651,1302,2603,3904,5206 ,7809,04015,82022.

It is ideal when the waterflow rate is fixed or varies over a narrow span (3:1), or where variations in flow are gradual, and on/offcycling does not occur. The pick Constant FlowHeater is delivered as a complete, compact systemand can be easily customized to meet your plant specifications.
