from setpoint the supply air temperature is. The factory
setpoint is 70–75°F [21-24°C], generally considered
“neutral” air.
ClimaDry Application Considerations
Unlike most hot gas reheat options, the ClimaDry option
will operate over a wide range of EWTs. Special
fl
ow
regulation (water regulating valve) is not required for low
EWT conditions. However, below 55°F [13°C], supply
air temperatures may not be maintained at 72°F [22°C]
because the cooling capacity exceeds the reheat coil
capacity at low water temperatures. Below 55°F [13°C],
essentially all water is diverted to the reheat coil (no heat
of rejection to the building loop). Although the ClimaDry
option will work
fi
ne with low EWTs, overcooling of
the space may result with well water systems or on
rare occasions with ground loop (geothermal) systems
(Note: Extended range units are required for well water
and ground loop systems). Since dehumidi
fi
cation is
generally only required in cooling, most ground loop
systems will not experience overcooling of the supply
air temperature. If overcooling of the space is a concern
(e.g. computer room well water application), auxiliary
heating may be required to maintain space temperature
when the unit is operating in the dehumidi
fi
cation mode.
Water-Source Heat Pumps with ClimaDry should not be
used as make-up air units. These applications should
use equipment speci
fi
cally designed for makeup air.
