Flo-Rite-Temp Model 8120
Flo-Rite-Temp Model 8120 Instantaneous Steam/Water Heater features a 8″ diameter shell and a non-helical straight internal tube bundle with end cap.
Flo-Rite-Temp Model 8120 has 120 GPM capacity with 15PSI steam at a 100°F temperature rise.
Flo-Rite-Temp Model 8120 features a unique feed forward design which features a differential pressure diaphragm actuated mixing unit integral to a shell and tube heat exchanger.
The Flo-Rite-Temp Model 8120 mixing unit manages the water flow through the heat exchanger based upon downstream hot water demand and eliminates the requirement for a modulating steam control valve.
Operating on constant low pressure (2-15PSI) steam, the Flo-Rite-Temp Model 8120 mixing unit supplies water to the heat exchanger where it is overheated and then returned to the mixing unit for proportional re-mixing with cold water to a pre-set outlet temperature.Request a Quote
The differential pressure diaphragm within the mixing unit rapidly responds to a change in system demand and significantly reduces the lag times typically associated with feed back/modulating steam control valve systems.
The Flo-Rite-Temp Model 8120 mixing unit’s 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.
Capable of controlling outlet temperatures +/-4°F, this principal of operation offers the additional relevant benefit of reducing the waterborne bacterial content of the water during the overheating process. In addition, with no water storage requirement, Flo-Rite-Temp Model 8120 water heaters are a sensible selection as a component of a broader system design initiative for Legionella risk reduction.
Accessible “non helical” admiralty brass straight tubes inside the carbon steel shell available mechanical cleaning and visual inspection. Non modulating constant steam pressure ensures condensate drainage and removes the potential for water hammer damage and corrosion. There is no steam control valve to maintain and typically no supplemental condensate return equipment required.
No storage tank, small footprint, access via a standard doorway and pre-piped packaged solutions reduce installation time, space and expenditure.
