Figure 5 : Installation possibilities for RHC 8000(M) air heater modules
Always ensure that the inlet perforated profile plate (when required) is installed at the air 'inlet' side of the heat
exchanger as shown in figure 5

IMITATIONS FOR
4.1 Heat exchanger compartment
4.1.1 Minimum airflow requirement through heat exchanger enclosure :
RHC 8000(M) RJL & DJL air heaters may be used for either push or pull through air heaters.
The min. airflow duty through the heat exchanger enclosure (see fig. 4 – table 2) must be
observed as indicated in table 3.

V1 = min. airflow required through enclosure
Note : The RHC units can be supplied with option 523 (perforated inlet plate at the air inlet side). This perforated plate
assures the proper efficiency of the heater in the lower airflow range (below V2 (cfr. table 3)). At higher airflow this
perforated plate can be removed thus reducing the pressure drop over the heating section without loss of efficiency (see
also section 10).
