The IVT Cabinet Heating system (ATEX) is designed to insure that during cold ambient
conditions, the internal cabinet temperature is maintained above -20
°
C (-4
°
F). This option is
REQUIRED where the ambient temperature drops below -20
°
C (-4
°
F) to maintain the ATEX
certification. See page 15 for more information regarding permissible ambient temperatures.
During startup and commissioning where the ambient temperature is below -20
°
C (-4
°
F ) the
cabinet heater system is energized prior to start up. Startup is delayed until the cabinet
temperature exceeds -20
°
C (-4
°
F). The internal cabinet temperature is monitored by use of a
temperature gauge located on the rear of the IVT cabinet.
Two radiators (heaters) warm the internal cabinet spaces; one is located in the mechanical
compartment and the other inside of the operator interface compartment. Each has an integral
thermostat to control the cabinet internal temperature. Thermostats turn the heaters ON at 10
°
C
(50
°
F) and OFF at 18C (65
°
F). The IVT Oil Mist Generator Cabinet Heating system for the ATEX
construction includes two enclosure radiators (heaters) with thermostats, wire terminal enclosure
an air temperature gauge and a power disconnect switch. The IVT cabinet enclosure is insulated
to retain radiated heat.
When the IVT Oil Mist Generator is equipped at the factory with the Cabinet Heating system, no
additional user connections or installation is required.
