Description
The Chromalox DRA Dragon is a rugged
industrial grade, self contained, highly mobile,
electric blower heater. The DRA can be left
unattended without the threat of poisoning
from combustion by-products associated with
fuel fired heaters. The built in safety features
include an adjustable thermostat to control the
outlet air temperature, auto-reset cutouts for
the fan motor and heating elements. The
thermostat provides settings for full off, fan
only and temperature control in the heating
setting. Dragon heaters feature a large, easily
accessible control and wiring compartment
containing a magnetic contactor; additional
safety is provided by a 120 volt control voltage
transformer and motor starter on 480 and 600
volt units. The bright red polyester powder
coated heating cylinder is highly visible and
can be rotated to direct heat or fan driven air
movement where it is needed. For assured
safety, all standard units meet the require-
ments of UL (File No. E7061) and CSA (File
No. LR40859).
Construction
Heating Cylinder
A structural frame consisting of 2 spun steel
rings and 2 formed steel channels support a
20 gauge steel cylinder phosphate coated for
corrosion resistance, and finished in red
polyester powder coat paint. The heating
cylinder pivots vertically to direct air flow.

Leg Assembly
Each side consists of a one piece, 12 gauge,
formed steel member, which accepts a steel
tubular handle, held in place with a 1 1/2" long
x 1/4" bolt on each side. The handle can be
raised from the shipping position if desired.
The rubber, pneumatic wheels are 10"
diameter and 3 1/2 wide to provide ease of
transporting the heater on irregular and gravel
surfaces. The large wheels make it easy to roll
up stairways without damage to decorative
step surfaces.
Fan Assembly
The self-centering fan assembly consists of a
totally enclosed, permanently lubricated motor
and a dynamically balanced aluminum fan
blade for smooth, quiet operation.
Controls
A thermostat, with a temperature range of
40°F to 100°F is included, with a full off
position, a fan only position and an adjustable
range of temperature settings in the heating
mode position. Each unit includes a 3 pole
magnetic contactor and auto-reset thermal
cutout. 480 volt and 600 volt units also
include a motor relay and 120 volt control
voltage transformer for personnel safety.
Safety Guards
Front and rear grills are 10 gauge, finished in
black polyester powder coat and are designed
to meet OSHA safety requirements.
Heating Assembly
The patented metal sheath Fintube
®
heating
elements consist of steel fins furnace brazed
on industrial grade .475 diameter steel sheath
tubular heaters for maximum heat transfer.
The elements are held in place with steel
bulkhead fittings for durability. The elements
feature a high temperature finish for corrosive
protection.

Cable packages include 25 feet Type SO
cable, with either 3-conductors or 4-conduc-
tors, depending on the heater requirements.
Each cable assembly includes the proper
cord (connector). Plugs are not included. All
models are factory wired for 3-phase, but
can be field wired for single phase, select plug
and cord accordingly.
SO = Hard Service Cord, 600V.
