Safety and Versatility
IND£ECO's ULTRA-SAFETM Explosion-proof
Unit Heater product line is designed with
both safety and versatility in mind. Unique
ULTRA-SAFETM construction features include:
· Industry's Lowest Ignition Temperature
Code Rating: T3C, 320°F (160°C)
· Group C Rating
· Redundant Overtemperature Protection:
Dual automatic reset thermal cutouts for
additional safety.
· Nontoxic Propy[ene Glycol Heat Transfer
Fluid: Other heat exchanger designs use
toxic ethylene g~ycol as their standard heat
transfer fluid.
· Low 70 PSIG Relief Valve Setting: This
assures that in an emergency, the initial
escaping vapor temperature remains below
the 320°F (~.60°C) ignition temperature.
Other heat exchanger designs are rated
up to 200 psig that result in temperatures
of 380°F (193°C).
· More Options: INDEECO offers a wide
variety of options and special features tn
reduce the installed cost and meet your
unique application requirements.
Standard Construction
Heat Exchanger- is an efficient liquid-to-air
design utilizing a copper tube core with
integral a[uminum fins. Industria[ grade
IND£ECO heating elements are immersed in
a nontoxic, inhibited, propytene glycol heat
transfer fluid that provides freeze protection
down to -49°F (-45%). The heat exchanger
is hydrostatically tested at 350 psig. A
pressure relief valve provides excess
pressure protection and is set at 70 psig.
Standard Fan Motor Assembly- consists
of an explosion-proof motor fitted with an
aluminum fan blade. The motor has double*
shielded, permanently lubricated ball bearings
and automatic reset line breaking thermal
overload protection. Motors furnished on
standard units operate at line voltage and
are prewired to the control enclosure so
separate field wiring to the motor is not
required. The standard motor is rated for
Class I, Groups C and D, Class II, Groups F
and G. The minimum operating temperature
is -'14°F (-25°0 and the minimum storage
temperature is -49°F (-45°C). Optional motor
ratings are described on page 7.
Cabinet/Louvers - are an industrial grade,
corrosion resistant construction fabricated
from powder coated ~.4 gauge steel. The
adiustable louvers have minimum opening
safety stops.
Controls - are factory mounted on the unit
heater. Standard built-in controls include
dual (redundant) automatic reset overtemper-
ature cutouts, controlling magnetic contactor,
24 Volt control circuit transformer and
incoming power terminal blocks.

Adjustable Thermostat T
Thermostat is adjustable from 50° to 90°F (~.0° to 30°C) range.
Factory installed on the unit heater beside the control enclosure.
Disconnect Switch This is an inexpensive and positive way to meet NEC/CEC requirements D
for a disconnecting means within sight of the heater.
A two-position switch wired to the control circuit for auto (automatic
Auto/Fan heat) and fan only control. This selector switch cannot be provided S
Selector Switch if option Code M is also specified.
Manual Reset This can be added to the built-in control package for triple N
Thermal Cutout overtemperature protection.
This provides both triple overtemperature protection and a
Manual Reset completely independent safety system since the backup contactor M
Thermal Cutout with is only controlled by the manual reset cutout. This option cannot
Backup Contactor be provided if option Code S is also specified.
"Heater On" Pilot Light Indicates when the electric heating elements are energized. L
Indicates when the thermal cutouts have tripped and the unit heater K
"Warning" Pilot Light needs servicing.
This can be provided when required for special external V
120 Volt Control Circuit thermostat circuit.
Custom Options
· Epoxy-coated them-duty motor, which has passed the
ASTM 8117 salt-spray test and is rated for outdoor use.
· Corrosion resistant iddite-coated heat exchanger.
Epoxy-coated fan blade, terminal box, and wiring conduit/fittings.

· NEMA 4X, 7, 9 (outdoor/corrosion resistant) terminal box. Epoxy-
coated built-on thermostat, disconnect switch, and selector switch
options can also be supplied for corrosion resistant applications,
but these built-on controls are not rated for outdoor use.
50 Hz Motor Optional motors for international requirements. H
Available for locations classified as hazardous due to the
Group E (Metal Dust) presence of metal dust. The motor and heater wilt be rated for
