Cold Ambient Option (Air Preheating and Cabinet Heating) for NEC constructions
The Cold Ambient Option (Air Preheating) option for NEC constructions is recommended when
the IVT Oil Mist Generator is installed in geographical locations where the minimum ambient
temperature falls below 15
°
F / -10
°
C. The IVT Air Pre-heater system is designed to insure that
during cold ambient conditions, proper air and oil temperatures are maintained at the oil mist
generator. The pre-heater is installed in the incoming air supply. A sensor at the inlet of the
heater senses the inlet air temperature. When the inlet air temperature falls below 40
°
F / 5
°
C, the
pre-heater is activated. The discharge temperature from the pre-heater is supplied to the mist
head and air/oil heater at a controlled 60
°
F / 16
°
C. A second sensor provides heater control and
high-low alarm input signals. A third sensor is used for high temperature heater cutout. The IVT
cabinet enclosure is insulated to retain radiated heat from the air pre-heater and discharge tubing.
When the IVT Oil Mist Generator is equipped at the factory with the air preheating system, no
additional user connections or installation is required.
