Semi-instantaneous steam/water heaters typicallyincludelower-capacity storage, with an integral steam control valve to deliver the heat exchange through an internally positionedelement or coil. Semi-Instantaneous Steam/Water Heaters are a lessattractiveoption because: ٕPoor low-flow temperature control creates an accumulationtank requirement.Accumulation tank creates recovery-time issues at peak demand.ՕHeating element/coil in generation/accumulation tank is susceptible to failure and cross contamination.Accumulation tanks have been identified as amplificationand colonization points for Legionella...

Speed of response Failure Safe The differential pressure diaphragm within the mixing unit rapidly responds to a change in system demand and signifi- cantly reduces the lag times typically associated with feed back/modulating steam control valve systems. The Flo Rite Temp mixing units diaphragm actuated design can be described as "failure safe" because in the event of a diaphragm failure the mixing unit will fail with a cold bias and will not allow hot water to exit the heat exchanger. > The Flo Rite Temp instantaneous Steam/Water heater has aunique feed forward design which features a differential...
