Reznor ULSA Rheco Heat Exchanger
The unique heat exchanger configuration comprises of individual four pass tubes.
As the modulating burner fires, heat is equally passed into the first pass tubes.
The tubes work from the rear of the heater towards the front, to remove as much heat as possible into the air flow.
Secondary heat exchanger comprises of a four pass pressed plate with large surface area.
Primary and secondary sections are welded using the latest in automated welding robots.
The increased surface area and positioning of the secondary plate within the air stream increases heat transfer.
Runs in permanent condensing mode with low flue gas temperatures.
Latent heat from the condensing operation is recovered and used as useful heat.
A modulating main axial fan option is available to reduce air flow over the heat exchanger during low fire mode.
An increased Delta T makes the discharge air much warmer.
The Reznor ULSA RHeco requires a 0-10v modulating signal which can be provided by the SmartCom controller.
This heater can not be operated with an old generation clock / thermostat.
