TFM 60Hz
Previously, the selection of a uid cooler involved using charts, correction factors and hand calculations to
determine the capacity and make the selection.
We have simplied the selection process. Our engineering department has created a computer program.
This provides exibility and streamlines the selection process

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)

Remote Radiators for Diesel and Gas Engines
A remote radiator is usually required with the larger style
of diesel engine. The Fluid Cooler is suitable for this type
of application. Designed to give the customer trouble free
operation, the multiple fan arrangement reduces the possibility of down time. Units are completely pre-assembled
and require only piping and electrical connections. (see

LOW AMBIENT OPERATION
60Hz
Fan Cycling Control
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.
