1.0 GENERAL DESCRIPTION

The Model 5474/5474A Integrated Heating System, shown in Figure 1, is
a 500 Watt heating system that consists of a stainless steel strip heating
element, 135°F (57°C), thermal overload sensor, power on indicator and a
110 cfm fan for use in small controlled environment chambers. In addition,
a weather-tight AC accessory outlet box with a GFCI outlet for 115 VAC or
a duplex North American outlet for 230 VAC is provided. The Model 5474
houses the components in a stainless steel enclosure measuring
16”Wx13”Hx3.125”D (41x33x8 cm). The 5474L, a larger version of the
5474, measures 30”Wx16.875”Hx4.125”D. On all 5474’s the heater, fan
and AC outlet are IEC power input modules.

The Model 5474A utilizes a stainless steel enclosure with 4 replaceable
HEPA filters and a gasket seal for installation onto the surface of the
chamber. The standard unit incorporates 3 IEC power connectors to
accept standard IEC power cords. Otherwise, the Model 5474A operates
the same as the Model 5474.

The system can be customized to meet most user requirements by adding
or removing accessories.
