Steam Control Produc

2020-1-16 · Steam Control Systems Steam is generated inside the boiler by heating treated condensate, above 212°F. The steam is then transported through pipes to the point of use, driving the heating process created by the steam. When the steam cools down and converts to condensate, it flows into the condensate unit, and eventually into the boiler feed unit.
