Fan Data - High Flow Cabinet Heaters
All COMBAT® High Flow heaters are fitted with three phase motors and belt drive fans to provide a flexible range of fan
performance curves. Table 2.2 shows the standard motor and fans drive arrangement for each model with reference to
the operational fan curve for each model.
The following ten performance graphs (Figs 2.7 to 2.16) show the performance of the fans with two curves. The first
one is
air flow v static pressure
so that an assessment of system performance may be made, the second one is
air flow
v fan motor current
so that a guide to motor performance may be made.
Note:
on some graphs there is a part of the curves that show that when the static pressure is low then the air flow is
high enough to cause a motor current significantly above the full load current recommended by the motor manufacturer.
Operation of the heater in this section of the curve is not recommended, however a 5% overload of the motor is
normally acceptable due to the high air flow over the motor keeping it cool.
It is advised that heaters are selected so that the resultant air flow does not fall below the normal expected air flow as
specified for the similar heat input model of the PGP or POP range as shown in the Data Table 2.1.
