The Pick Constant Flow Steam Injector is used wherever a relatively constant flow of heated liquid at a precisely controlled temperature is required.
The Constant Flow Steam Injector mixes medium-to-high pressure steam with cold water and delivers instant hot water. It is ideal when the water flow is fixed or varies over a narrow span (3:1).
The Pick Heater is delivered as a complete, compact system and can be easily customized with additional controls, valves, and instrumentation to meet your plant specifications. Save space, energy and maintenance costs using a Pick Constant Flow Heating System.
For water flow turndown beyond 3:1 or rapid start-stop cycling applications, please refer to our Variable Flow design.

No Steam Hammer
Eliminates harmful vibration and steam hammer which can lead to product and equipment damage.
Exceptional Temperature Control
Precise, accurate temperature control +/- 1°C
Energy Efficient
100% heat transfer - cuts fuel costs as much as 28% compared with indirect heat exchangers
Low Liquid Pressure Drop
Pressure drop does not exceed 2 PSI (0.14 BAR) under design flow rates
The Pick Heater is an engineered product and heater selection is primarily based on Steam Demand.
For preliminary heater selection use the following Sizing Formula. Next match the liquid flow rate to the appropriate pipe size. The selection should be verified by your local Pick Heater Rep or a Factory Sales Engineer.
Please contact us with questions.
Sizing Formula:
Steam Demand
(lb/hr)= 0.43 x flow(GPM) x ∆ T (ºF)
or
(kg/hr) = 0.092 x flow(LPM) x ∆ T (ºC)
Example: 200 GPM x 50ºF temperature rise x 0.43 = 4,300 lb/hr of steam. You would require a 6X50-3 which has a maximum rated steam capacity of 5,000 lb/hr, and a maximum water flow rate of 230 GPM with threaded connections (500 GPM with welded flanged connections).
