An electric preheat coil is an available
option for all PRO-C units to limit the
risk of frost formation for projects that
involve high indoor humidity and/or
extreme winter design conditions.
Applications involving space
conditions that will exceed 30 percent
relative humidity when the outdoor
air temperature is below 0°F, should
be evaluated to see if preheating is
necessary. In such cases it is best to
contact your local Carrier-ERV Systems
representative for assistance.
Most applications that do not
involve space humidifi cation will function
as desired without preheating. Even in
extremely cold climates, 10 to 15 degrees
of preheat, which is only operated on
extreme days, will usually prove adequate
to avoid frost formation.
Table 6 should be used to select
the appropriate size electric pre-heater
for a given application. Often it is best
to make this selection in conjunction
with your local Carrier-ERV Systems
representative to assure proper sizing.
