Data Center / Computer Rooms
Fluid Coolers are suitable for use with Computer Room
Air Conditioning (CRAC) Units. (see Illustration below)
Dry Type Fluid Coolers are particularly suitable for applications where long pipe runs of refrigerant piping to
an air cooled condenser are not practical. Cooling Tower
maintenance and winter operation issues are eliminated.
Piping can be easily installed and low ambient control
can be used using water regulating valves. Fluid cooler
can be easily connected to city water for emergency use.
The glycol loop is sometimes connected to a “Free-Cooling” Economizer Coil within the CRAC unit, which allows
for partial free-cooling when the glycol loop temperature
is below the CRAC units return air temperature.

Industrial Glycol /Water Cooling Systems
Water pollution issues and water conservation have
become critical in recent years. The “Once-Only” use of
water for industrial process cooling has been wasteful
and often unnecessary. By using a dry type Fluid Cooler,
glycol/water for industrial process cooling applications
can be cooled to within 10°F (6°C) of the ambient dry
bulb temperature. The water is continuously re-circulated
and remains in a closed system so reducing the problem
of corrosion normally encountered in non re-circulated
systems.
Considerable savings can be affected by using a Dry
Type Fluid Cooler. Many industrial applications have
seen water consumption being reduced by millions of gallons and reduced maintenance costs to a fraction of that
experienced prior to the use of a closed non re-circulated
system. (see illustration below)

(2) Sound level pressure at 30 ft (10m)
(3) Not including headers.
When a remote air cooled Fluid Cooler is installed outdoors, it will be subjected to varying temperatures. Within
many areas, winter to summer annual temperature swings
can be as high as 120°F (48.9°C) or so. This will have a
major impact on the performance of the Fluid Cooler. As
the ambient temperature drops, the Fluid Cooler capacity
increases due to a wider temperature difference between
ambient air and entering uid temperature. As this happens, the leaving uid temperature drops as well.
Cycling of the Fluid Cooler fans helps control the leaving
uid temperature. With this approach to solving low ambient problems, fans are taken off-line one at a time. It is not
recommended that multiple fan Fluid Coolers cycle more
than two (2) fans per step. The reason for this is that the
uid temperature will change drastically as several fans
are taken off-line at the same time. This could result in
excessive tube stress within the unit, due to rapid expansion and contraction of the coil which could lead to needless tube failure.
Fan Cycling Control Schedule
Fans closest to the inlet header should be set to run whenever the uid circulating pump is running.
Substantial fan motor power savings can be realized as
well using this method.
For low ambient conditions, optional
Aquastats (Fluid Temperature
Controllers) are used to cycle fans
on and off as required to maintain
constant leaving glycol/water
temperature as per the schedules below.

ABOUT EC MOTORS
EC MOTORS
60Hz
Fluid coolers utilizing electrically commutated motor
(EC motor) technology offer many benets; Improved
Efciency, Reduced Sound Levels, Speed Control,
Simplicity and Reliability
Efciency
The speed control function of an EC motor allows the
condenser to run at optimized energy levels at different operating conditions. Up to 75% in energy savings can be realized when comparing the EC motor
speed control method to a conventional fan cycling
method.
ELECTRICAL DATA
ECM 1075 RPM MODELS - SINGLE PHASE
Sound
As EC motor speeds vary for different operating
conditions they also offer reduced sound levels when
compared to conventional motor running full speed.
Sound levels are reduced on cooler days and in
evenings.
Simplicity and Reliability
The installation and control of EC motors is very
simple compared to other methods of speed control
used on conventional AC motors. Lower running operating temperatures and smooth transitional speed
changes make EC motors durable and reliable.

EC MOTOR APPLICATION
EC MOTORS
60Hz
Motors With Built-in Variable Speed –
Optional “E” Fan/motor Code
Units with an E (in nomenclature) motor designation use
an EC (electronically commutated) motor / fan combination to provide variable speed fan motor control. ECM fan/
motor combinations use DC motors with integral AC to DC
conversion allowing direct connection to AC mains with the
energy saving and control benets of a DC motor. Ideally
the motors on the uid cooler should all be EC and simultaneously slow down /speed up together. This provides
for maximum energy savings. However some applications
may exist where just the last fan or pair of fans (ones
closest to header) is solely EC motors. (The remaining
conventional type motors are then cycled off by fan cycling
temperature controls).
Important Warnings:
!
(Please read before handling motors)
1. When connecting the unit to the power supply, dangerous voltages occur. Due to motor
capacitor discharge time, do not open the motor within 5 minutes after disconnection of all phases.
2. With a Control voltage fed in or a set speed value
being saved, the motor will restart automatically
after a power failure.
3. Dangerous external voltages can be present at the
motor terminals even when the unit is turned off.
4. The Electronics housing can get hot.
5. The cycling on and off of EC motors should be
controlled by the DC control voltage (i.e. 0V DC will turn motor off). Excessive cycling of the motor by line voltage contactors may cause stress on
the motors and reduce the motor life.
Speed adjustment Characteristics
The EC motor varies its speed linearly based on a 1-10V
input signal. At 10 VDC, the motor runs at full speed. At 0
to approx. 1 VDC, the motor turns off. A chart of the speed
control curve is shown below. The motor can be controlled
at any speed below its nominal RPM.
Full RPM
RPM
1
Control voltage [V dc]
Control Signal
The input control signal can be supplied by an external
control signal or from a factory installed proportional temperature control. Units with factory installed proportional
temperature controls require no installation wiring and are
adjusted with initial factory settings. These may require
further adjustments to suit local eld conditions.
External Control Signal (Supplied by others)
Contact control manufacturer for setup of external controller to provide a 0-10 VDC control signal. Wire the control
signal to terminal board in unit control box. Refer to the
uid cooler EC wiring diagram for typical external signal
control wiring.

features:
• Temperature Set point
• Throttling range

Throttling range
The throttling range potentiometer controls how far the
system uid temperature deviates from the control set
point to generate a 100% output signal from the control
and is adjustable from 2oF to 30oF range. The throttling
range determines how quickly the motor will reach full
speed when detecting a change in uid temperature. For
example, if the set point is 90oF and the throttling range
is 10oF when the system temperature drops below 90oF,
the fans will be off. When the system temperature reaches
100oF (90 + 10) the fans will be at maximum full speed.
To make the fans ramp more slowly the throttling range
should be increased. To maximize sound reduction and
energy efciency and to provide for the most stable control, it is recommended this setting be left at 10oF.
Reverse acting or direct acting mode of operation
The reverse acting/direct acting jumper is used to ensure the controller responds correctly to the desired uid
temperature. In Direct Acting (DA) mode, the motor speed
increases as the temperature rises above desired set
point. For proper uid cooler operation, this jumper MUST
be in Direct Acting (DA) mode. Failure to ensure J1 jumper
is in direct acting mode will cause the system to trip on
high uid temperatures.
Operation Mo de
Jumper Posi tions
Fluid Temperature Set point
The uid temperature set point potentiometer is adjustable
from -30oF to 130oF.
Note: Very low set points may cause the fan motors to run
full speed continually even if the uid cooler is properly
sized. The fans will turn off if the uid temperature falls
below the desired set point.
Minimum Output
The minimum output potentiometer controls the minimum
signal sent to the motor and is factory set at 0%. It is adjustable between 0 and 60% of the output range. If this is
adjusted to 50%, the motors will not start running until 5V
is applied to the motor. The motor will start running at 50%
of full speed. To maximize sound reduction and energy
savings and to provide the most stable control, it is recommended this setting be left at 0%.
Integration constant
The integration constant switch provides ability to change
controller from a proportional only control to a proportional plus integral control. To provide the most responsive
system and to maintain a stable uid temperature, it is
recommended the integration setting be left on “fast” with
the Mode switch set to OFF (Proportional AND Integral
activated)
ADEQUATE PRECAUTIONS MUST BE TAKEN, AFTER FIELD LEAK TESTING TO INSURE REMOVAL OF
WATER IN TUBES. IT IS RECOMMENDED THAT AN INHIBITED GYLCOL SOLUTION BE USED TO FLUSH
THE COMPLETE COIL. FAILURE TO TAKE PRECAUTIONS CAN RESULT IN FROZEN TUBES SHOULD THE
UNIT BE SUBJECTED TO LOW AMBIENT CONDITIONS BEFORE PLACED IN OPERATION.
INSPECTION
A thorough inspection of the equipment, including all
component parts and accessories, should be made
immediately upon delivery. Any damage caused in
transit, or missing parts, should be reported to the
carrier at once. The consignee is responsible for
making any claim for losses or damage. Electrical
characteristics should also be checked at this time to
ensure that they are correct.
LOCATION
Before handling and placing the unit into position a
review of the most suitable location must be made.
This uid cooler is designed for outdoor installation.
A number of factors must be taken into consideration
when selecting a location. Most important is the
provision for a supply of ambient air to the uid cooler,
and removal of heated air from the uid cooler area.
Higher uid temperatures, decreased performance, and
the possibility of equipment failure may result from
inadequate air supply.
Other considerations include:
1. Customer requests
2. Loading capacity of the roof or oor.
3. Distance to suitable electrical supply.
4. Accessibility for maintenance.
5. Local building codes.
6. Adjacent buildings relative to noise levels.
WALLS OR OBSTRUCTIONS
All sides of the unit must be a minimum of 4 feet
(1.25 m) away from any wall or obstruction.
Overhead obstructions are not permitted. If enclosed
by three walls, the uid cooler must be installed as
indicated for units in a pit.

LIFTING INSTRUCTIONS
Air cooled uid coolers are large, heavy mechanical
equipment and must be handled as such. A fully
qualied and properly equipped crew with necessary
rigging should be engaged to set the uid cooler into
position. Lifting holes have been provided at the corners
or along sides for attaching lifting slings. Spreader bars
must be used when lifting so that lifting forces are
applied vertically. See Fig. 2. Under no circumstances
should the coil headers or return bends be used in
lifting or moving the uid cooler.
FIG. 2
FIG. 1
LEG INSTALLATION INSTRUCTIONS
Ensure the unit is placed in a level position (to ensure
proper drainage of uid). The legs should be securely
anchored to the building structure, sleeper or concrete
pad. The weight of the uid cooler alone is not enough
to hold in place during a strong wind, the legs must be
anchored.
1) Assemble centre leg as shown.
Remove two bolts from bottom ange of unit side panels
that match the hole pattern on the top anges of both legs.
Attach center legs using hardware provided at center
divider panel location.
Replace bolts that were removed from from side panels
to secure leg assembly to bottom anges of unit side panels.
2) Assemble four corner legs to bottom anges
on unit side panels and end panels using hardware
provided, at matching mounting hole patterns.
All legs are the same.

ELECTRICAL WIRING
All wiring and connections to the air cooled uid cooler must
be made in accordance with the National Electrical Code
and all local codes and regulations. Any wiring diagrams
shown are basic and do not necessarily include electrical components which must be eld supplied. (see pages
7,8,10 for typical wiring diagrams).
Refer to the Electrical Specications table on pages 5, 9 for
voltage availability and entering service requirements.
SYSTEM START-UP CHECKS
1. Check the electrical characteristics of all components
to be sure they agree with the power supply.
2. Check tightness of all fans and motor mounts.
3. Check tightness of all electrical connections.
4. Upon start-up, check fans for correct rotation. Air is
drawn through the condenser coil. To change rotation
on 3 phase units reverse any two (2) fan motor leads.
5. All system piping must be thoroughly leak checked
before a refrigerant charge is introduced.
HYDRONIC SYSTEM COMPONENTS
MAINTENANCE
A semi annual inspection should be carried out by a
qualied refrigeration service mechanic. The main power
supply must be disconnected.
1. Check electrical components. Tighten any loose
connections.
2. Check control capillary tubes and lines for signs of
wear due to excessive vibration or rubbing on metal
parts. Secure if necessary.
3. Check tightness of all fans and motor mounts.
Remove any deposits which could effect fan balance.
Note: Fan motors are permanently lubricated and
require only visual inspection.
4. Clean the uid cooler coil using a soft brush or by
ushing with cool water or coil cleansers available
through NRP (National Refrigeration Products Inc.)
5. Update service log information (back page of service
manual)
PIPING CONSIDERATIONS
1. All piping must comply with local city and plumbing
codes.
2. Correct choice of pipe material, diameter, velocity and
friction loss (pressure drop) can result in glycol systems
running at peak efciency and performance and hence
least cost.
3. Studies have indicated that iron pipes are most
susceptible to corrosion, followed by galvanized steel,
lead, copper and copper alloys (i.e brass). PVC is
generally no-corrosive.
4. Good glycol system design therefore requires that
Galvanized Pipe NOT be used and a glycol manufac turer provide the appropriate Corrosion Inhibitor.
5. Parallel, Direct and Reverse Return piping (see
illustration on page 23) networks are the most common
used as they allow the same temperature uid to be
available to all loads and heat rejection devices (Fluid
Coolers). Actual piping should be determined by a
qualied hydronic system designer, based on site and
design requirements.
6. Isolation Valves should be provided for easy removal of
hydronic system components, for repair, maintenance or
replacement.
7. All piping should be leak tested after installation.
8. A pressure reducing valve should not be used in a glycol
hydronic system.
PUMPING SYSTEM
Pumps
1. Mechanical seal type pumps must be used for glycol
systems.
2. Pumps are selected based on Total System Flow and
Total Friction Loss (Highest Pressure Drop) through:
a. The Fluid Cooler
b. The Load (Chiller, CRAC Unit, etc)
c. Supply/Return Glycol Piping, Valves & Fittings
The Sum of the above is the “Total Head” or Pressure
Drop of the system, typically measured in ft-H2O.
3. This is a closed loop system. A counterhead acts on the
pump suction so no allowance is required for vertical lift
as in an open loop (i.e Open Cooling Tower) system.
4. Many hydronic system designers are specifying and
many end-users are purchasing “Pump Packages”.
These Pump Packages come ready for nal pipe and
electrical connection, allowing the installer to focus on
overall pipe connections.
5. Pumps in Parallel are recommended for standby operation where pump failure may interfere with a
critIcal application ( i.e Data Center Cooling - N + 1
Design).
