Flo-Rite-Temp Model 535

Description

Flo-Rite-Temp
Model 535 Instantaneous Steam/Water Heater features a 5″ diameter shell
and a non-helical straight internal tube bundle with end cap.

Flo-Rite-Temp Model 535 has 35 GPM capacity with 15PSI steam at a 100°F temperature rise.

Flo-Rite-Temp Model 535 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 535 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 535 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.

Speed of Response

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.

Failure Safe

The Flo-Rite-Temp Model 535 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.

Temperature Control and User Safety

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 535 water heaters are a sensible selection as a
component of a broader system design initiative for Legionella risk
reduction.

Ease of Maintenance

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.

Ease of Installation

No storage tank, small footprint, access via a
standard doorway and pre-piped packaged solutions reduce installation
time, space and expenditure.
