Steam/Water Heater
- Tank-Type Heaters (Feedback): These have significant storage capacity but are less efficient due to slow response times, large space requirements, and potential for Legionella bacteria growth.
- Tankless Instantaneous Heaters (Feedback): These lack storage capacity, leading to thermal lag and potential damage from water hammer.
- Semi-Instantaneous Heaters (Feedback): These have lower storage capacity but suffer from poor low-flow temperature control and maintenance issues.
- Utilizes a feed-forward system that eliminates the need for a temperature sensing feedback element, providing rapid and accurate response to system demand.
- Operates with constant, non-modulating steam pressure, reducing wear and tear.
- Ensures consistent outlet temperature with no thermal lag, enhancing safety by failing to cold water flow in case of component failure.
- Saves space and energy compared to traditional systems.
- Eliminates temperature swings and thermal lag.
- Designed for easy maintenance with straight tubes for cleaning.
- Reduces health hazards associated with standing water.
- Models include 415, 535, 665, and 8120, with varying dimensions and connection specifications.
- Materials used include stainless steel, brass, and carbon steel, ensuring durability and compliance with standards.
Catalog excerpts
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...
