Flo-Rite-Temp^™ Steam Instantaneous Water Heaters

The Armstrong feed-forward design eliminates the troublesome temperature regulator and uses a differential pressure diaphragm valve to regulate flow and control temperature. The valve teams up with a shell-and-tube heat exchanger to complete the system.

The idea is simple: Overheat water in the heat exchanger and then blend it (as needed) with proportional amounts of cold water to achieve the correct outlet temperature for a wide range of flows. There’s no storage tank or potential health hazard posed by standing water.

Get a jump on peak demand periods

The differential pressure diaphragm acts immediately upon a change of demand, so there’s no lag time. You get all the hot water you need—up to the unit’s capacity—instantly. What’s more, if the diaphragm fails, a spring returns the valve to a closed position (cold), so there’s no danger of scalding.

Make maintenance a straight, easy shot

Virtually everything about the design and operation of the Flo-Rite-Temp reduces maintenance. For starters, the tubes inside the carbon steel shell are straight, for easy mechanical cleaning. And steam pressure in the heat exchanger is not modulated but constant, which ensures condensate drainage and nixes potential water hammer and corrosion.

Multiply your savings

When it comes to replacing a bulky storage tank system, the choice is clear. The Flo-Rite-Temp consumes dramatically less floor space, and you don’t have to tear out walls to install it. In fact, it slips through a standard doorway. Payoff? Lower installed cost. Here’s another advantage: An energy-efficient Armstrong Flo-Rite-Temp won’t waste energy by constantly reheating stored water. You can insulate the heat exchanger to save even more.
