Variable Flow

What is a “Variable Flow” Steam Injection Heater?

The Pick Variable Flow Steam Injector mixes medium-to-high pressure steam with cold water and delivers instantaneous hot water at a precisely controlled temperature over a wide range of water flows.

It is used to accommodate wide variations in demand and frequent start-stop applications and is ideally suited as a central heating system for multiple use points such as hose wash-down stations or plant sanitation. Standard systems can handle 12:1 water flow turndown or designed with dual control valves for up to 100:1 water flow turndown.

The Variable Flow system is ideal for replacing inefficient heat exchanges, storage tanks, steam spargers, and problematic individual steam/water mixing stations.
