be hazardous to users or could damage equipment.
Read and take precautions before proceeding.
Numbers within shaded squares indicate tasks or steps
to be performed by the user.
A diamond indicates the equipment’s response to an
action performed by the user.
An open box marks items in a checklist.
A shaded circle marks items in a list.
You must be familiar with all safety procedures concerning
installation, operation and maintenance of this equipment.
Responsible safety procedures include:
●Thorough review of this User Guide, paying particular
attention to hazard warnings, appendices and related dia-
grams.
●Thorough review of the equipment itself, with careful
attention to voltage sources, intended use and warning
labels.
●Thorough review of instruction manuals for associated
equipment.

UGH017/0500 Series 1 Portable Chillers, PLC Control INTRODUCTION 1-3
We design equipment with the user’s safety in mind. You can
avoid the potential hazards identified on this machine by fol-
lowing the procedures outlined below and elsewhere in the
User Guide.
ATTENTION:
READ THIS SO NO
ONE GETS HURT
WARNING: Improper installation, oper-
ation, or servicing may result in equip-
ment damage or personal injury.
This equipment should only be installed, adjust-
ed, and serviced by qualified technical person-
nel who are familiar with the construction, oper-
ation, and potential hazards of this type of
machine.
All wiring, disconnects and fuses should be
installed by qualified electrical technicians in
accordance with electrical codes in your region.
Always maintain a safe ground. Do not operate
the equipment at power levels other than what
is specified on the machine serial tag and data
plate.
WARNING: Electrical hazard
Before performing any work on this item, dis-
connect and lock out electrical power sources to
prevent injury from unexpected energization or
startup.
CAUTION: Hot Surfaces
Always protect yourself from hot surfaces when
working on the Portable Chiller, especially when
working on or around the compressor and con-
denser. These devices can reach up to 160 °F
(71 °C). Allow these devices to cool before per-
forming any maintenance or troubleshooting.
CAUTION: Ventilation hazard
The unit requires a clean and well ventilated
operating environment. Do not place anything
on top of the unit while operating. Units with
fans require unrestricted outlet air flow.
Water-cooled units require a minimum of one
foot clearance around the perimeter for service-
ability. Air-cooled units require a minimum of two
feet clearance around the perimeter for service-
ability and proper air flow.

DESCRIPTION

The Conair Series 1 Portable Chillers provide self-contained
sources of chilled water and are available in either water- or
air-cooled models. Ranging in size from 1.5 Hp to 13 Hp in
the air-cooled configuration and 1.5 Hp to 15 Hp in the water-
cooled design [approximate capacities of 1.5 tons of refrigera-
tion to 15 tons of refrigeration]. Pump selections are available
to match most process flow and pressure requirements.
The normal temperature range of discharge chilled water is
20 °F (7 °C) to 70 °F (21 °C). For applications requiring tem-
peratures of 40 °F (4 °C) and lower, mix glycol with the
water to the correct percentage.
The Air-cooled Portable Chiller A1 Models and Water-cooled
Portable Chiller W1 Models are designed to provide chilled
fluid for industrial applications requiring 24-hour-a-day per-
formance. Units are totally self-contained for easy, economical
installation. All parts wetted by the process are non-ferrous.
To operate, simply connect the power source, process piping
and fill with water or with industrial grade ethylene glycol or
propylene glycol (but not automotive antifreeze).
These chillers are ideal for machine-side cooling to maintain
process temperatures in an injection molding machine or
extruder and wherever you need a small, portable cooling unit.
Nominal capacities range from 1.44 to 14.68 tons for the
water-cooled models and from 1.18 to 10.95 tons for the air-
cooled models. Capacities are based on standard pump sizes
and delivering 50 °F (10 °C) water.
Operation of these units differ only in the medium used to
remove heat from the refrigerant in the condensers. Water-
cooled models use 85 °F (29 °C) or lower cooling water from
a tower, well, or city service; air-cooled models use 95 °F
(35 °C) maximum ambient air.
Choose Water-cooled Portable Chillers where tower water or
another inexpensive water source is available. Choose Air-
cooled models for maximum portability of the unit. Water-
cooled models are equipped with brazed plate or tube-in-tube
condensers. Air-cooled models use aluminum-fin, copper-tube
condensers.
All standard voltages are available.
WHAT IS THE
PORTABLE
CHILLER?
Series 1 Portable Chillers, PLC Control UGH017/0500
2-2 DESCRIPTION

The Conair A1 and W1 Portable Chillers can be used any-
where a reliable source of process cooling water - with stable
temperature control - is required.
These portable chillers are available for cooling injection
molding, blow molding, thermoforming, extrusion, air com-
pressors, metal plating, anodizing, degreasing, heatset/web
offset printing presses, and dryer after-coolers.
Roll the air-cooled condenser models next to the heat source
connect it and plug it in. They can operate almost anywhere.
The water-cooled condenser models require a source of con-
denser water. Normally used in conjunction with a recirculat-
ing evaporative cooling tower system, the units have slightly
better operating energy efficiencies.

LIMITATIONS
Conair Series 1 Portable Chillers are designed to provide
chilled water for industrial applications requiring 24-hour-a-
day performance. Units are self-contained and easy to install
and maintain. Choose the Conair Series 1 Portable Chillers
based on the cooling load and the capacity of the unit. Pick
your Conair Series 1 Portable Chillers based on:
● Cooling load
Choose a portable chiller that has 20% more capacity than
the process load.
● Location
Choose a water-cooled model if the unit will be located in
an air-conditioned area and a source of condenser water is
readily available (i.e. cooling tower water). Do not locate
either portable chiller model outside unless the unit is
specially modified.
● Temperature
The portable chiller has a standard setpoint temperature
range of 20 °F (7 °C) to 70 °F (21°C).
Use this information as a general guide. Consult your Conair
representative for assistance when choosing a Conair Portable
Chiller.

SPECIFICATION NOTES
✝ Based on 50 °F (10 °C) water temperature (100% water) leaving the chiller, standard pump selections, 85 °F (27 °C) condenser water supply
@ 25 psi minimum, for the 60 Hz units. For the 50 Hz units, multiply the capacity by 0.8 Consult factory for other conditions. Capacity ratings
are (+-) 5% based on compressor manufacturer’s ratings and are subject to change without notice.
‡ Based on 50° F (10 °C) water temperature leaving the chiller and 60 °F (16 °C) water temperature returning to the chiller (except W1-1.5
which has 55 °F (13 °C) water temperature returning to the chiller).
§ Pressure at pump discharge. See Pressure Tables in the Appendix for evaporator and condenser pressure drops.
