Features

• APPLICATIONS — Inter-Temp unit coolers are ideally
suited for a wide range of coolers and freezers. ITA
models are designed for use in coolers above 35°F.
ITE, ITG, and ITH units are suited for 35°F coolers,
when mechanical defrosts are required, as well as for
freezers with temperatures ranging down to -30°F.

• Sizes — There are 37 models offered, with capacities
from 10,500 BTUH up to 69,000 BTUH @ 10°TD.
Air flow ranges from 3,320 CFM to 9,130 CFM.

• HOUSING — Each unit is constructed with a rust-free,
heavy gauge, textured, aluminum housing which is
light weight yet extremely durable. Air and electric
defrost models have hinged drain pans to allow for con­venient servicing and maintenance (Hot Gas drain pans
are not hinged). Slotted hangers are provided on all
units for fast installation.

• COIL — Seamless copper tubes are staggered and
mechanically expanded into heavy gauge corrugated
aluminum fins to assure maximum heat transfer. Die
formed fin collars are provided for accurate fin spacing.
Heavy gauge hangers are fastened directly to the tube
sheet of the coil to provide high structural strength.

• REFRIGERANTS — Inter-Temp unit coolers are
designed for most refrigerants including, R-22,
R-404A, R-134a, R-502 and R-507. Please specify
system refrigerant requirements when ordering. A
separate compartment is provided for all refrigerant
connections which allows ample room for internal
mounting of expansion valves. Inter-Temps can also
be used with chilled water or glycol solutions, contact
factory for selection.

• Fans — Powerful heavy duty aluminum fans are
individually balanced to provide vibration free operation.

• Wire fan guards — Standard heavy gauge wire fan
guards are epoxy coated for corrosion resistance.
Optional air straighteners are available for increased
air throw when required.

• Mot o rs — PSC-Permanent Split Capacitor or
EC-Electronically Commutated, ball bearing type,
life lubricated and thermally protected. Inter-Temp unit
coolers use either 1/8 HP, 1050 rpm or 1/3 HP, 1075
rpm motors.

• Air Throw – Air throw is greatly affected by installa­tion variables. Optimum air throw is obtained by high
ceiling with no interference from beams, or return air
restrictions. Inter-Temp unit coolers will throw air up to
50 feet under ideal conditions, 60 to 70 feet with air
straighteners.

• ELECTRICAL — Available in 115V/1, 208/230/1,
208/230/3, 460/1 or 460/3. Inter-Temps can also be
operated on 220/1/50, 220/3/50, 380/1/50 and

80/3/50 power. All components are factory wired to

3
convenient screw type terminal blocks. A large
compartment is supplied for all electrical components
and is easily accessible by removing the end panel.

• AIR DEFROST — Available on ITA series only, for
use in coolers at +35°F and above. Complete air
defrost systems are available from Russell.

• ELECTRIC DEFROST — These units are available
as ITE models. The placement of heaters within
the refrigeration coil allows for a more efficient and
rapid defrost cycle than other designs. This
arrangement enables the energy from the heaters
to be conducted from the center of the core out,
providing an even defrost pattern. All heaters are
factory installed and wired to screw type terminal
blocks, allowing for quick field hook up or change
over from 1 to 3 phase with the installation of
jumper wires. Separate, fixed defrost termination,
fan delay and heater saftey controls are factory
mounted for optimum performance of each control
func tion. Drain pans are heated for fast, reliable
drainage. Timer and contactors are available as
options. Complete electric defrost systems are avail­able from Russell. Contact the factory for details.

• HOT GAS RE-EVAP DEFROST — Available on all
but the ITA models. These units include separate
fixed defrost termination and fan delay controls which
are factory mounted for optimum performance of
each control func tion. A hot gas drain pan circuit is
provided, thus eliminating the need for electric heat
and additional wiring. A heat exchanger/re-evapora­tor is supplied with every unit. Refer to the current
Russell Technical Bulletin HG for piping. Complete
Hot Gas Re-Evap systems are available from
Russell, contact the factory for details.

• HOT GAS REVERSE CYCLE DEFROST —

Available on all but the ITA models. These units
include separate fixed defrost termination and fan
delay controls which are factory mounted for opti­mum performance of each control function. A hot gas
drain pan circuit is provided, thus eliminating the need
for electric heat and additional wiring. Refer to the
current Russell Technical Bulletin HG for piping.
This unit is also used for Alternating Evaporator
System.
