Unmatched
reliability
Heavy-duty
construction, high
performance design
and our five-year
mechanical warranty
ensure consistent,
fully-rated cooling
over a wide range of
flow and temperature
requirements.

Low energy
consumption
Fluid cooling equipment
minimizes the energy
consumption of the
entire system because it
provides lower operating
temperatures – saving
money while conserving
natural resources.
Low noise
Centrifugal fans, a
fully-enclosed falling
water area and
optional sound
attenuation create one
of the quietest tower
configurations on
the market.
Smaller
footprint
Forced-draft
counterflow design
requires considerably
less plan area than
crossflow towers.
Ease of
maintenance
An extra large entry
panel makes the
interior of the unit
easy to access
for service and
maintenance. For even
greater access, the
motor and drive are
located outside the
plenum area near
the grade.
Reliability and performance. When specifying components
for high-end applications, they’re the most important
considerations for your cooling solution. And the Marley MC
Fluid Cooler delivers, with CTI-certified performance, low noise
and a space-saving footprint for installation practically
anywhere. Suitable for all critical indoor and outdoor
applications, the MC Fluid Cooler provides these built-in
performance advantages:
What every premium installation demands.

Features of the MC Fluid Cooler
High velocity, low drift eliminators
guarantee drift rates <0.005%
Distribution system access via an
optional ladder or platform
Extra large rectangular access
doors for easy maintenance
Optional S300
construction for extended life
5-year mechanical warranty for all
mechanical components and support

POPULAR OPTIONS
Welded stainless steel collection basin – for extra protection, all collection basin parts
exposed to the circulating water, including structural members projecting into the basin
(plus attaching hardware and all basin options) are heavy-gauge series 300 stainless steel.
Electric basin heater – incorporating a stainless steel electric immersion heater with
magnetic contactor and solid state circuit board can prevent freezing during operation
in cold weather. A pump heat trace comes standard with the basin heater package.
Solid state water level control package – monitors basin water level with solenoid-valve
water makeup. Configurations include makeup along with high and low water level alarm
and cutoff and electric basin heater cutoff.
Positive closure dampers – gives the added security of safe operation in freezing weather by
trapping heat inside the fluid cooler while fans are inoperable. Electric or pneumatic actuator
operation allow for flexibility during design.
Vibration switch – protects against mechanical failure should the tower experience high
vibration levels. Automatically shuts down the motor. Manual reset ensures inspection
to correct initial vibration cause.
Variable speed drive – provides the ultimate in temperature control, energy management,
sound control and mechanical equipment longevity.
Control systems – range in sophistication from standard fan and pump starters to
Programmable Logic Controllers that work in conjunction with your building or process system.
Sound attenuation – baffles can be installed across the length of the air inlet, as well as the
air outlet opening. All baffles are constructed of perforated sheet metal and contained within a
self-supporting steel box.
For fully-rated thermal
performance, low sound levels

operating reliability and simplified
maintenance requirements,

Frequently Asked Questions
Q Why should I purchase a fluid cooler instead of a cooling tower/heat exchanger combination?
AFluid coolers reduce piping and system complexity by combining three pieces of equipment (cooling tower/
heat exchanger/pump) into one unit. This can prove beneficial in critical application areas.
In addition, a cooling tower and heat exchanger usually have a combined approach temperature of about 4°C.
With a closed circuit fluid cooler, certified approaches as low as 3°C can be guaranteed – allowing for colder
process fluid temperatures and greater efficiency during operation.
Closed circuit systems also protect the process fluid from contamination – reducing fouling and scaling
tendencies within sensitive systems. Clean closed loops result in greater efficiency, reduced energy costs
and reduced maintenance costs.
Q What are some common closed circuit/fluid cooler applications?
ATypical closed circuit applications include any process that is sensitive to fouling and corrosion. Many HVAC
applications are ideal for fluid coolers. Fluid coolers are also ideal for installations where the process fluid
is something other than water. Although certified with water as the process fluid, the MC Fluid Cooler can
effectively discharge heat from other fluids such as glycol, oil or other unusual water mixtures.
Common applications for the MC Fluid Cooler: Common sites for the MC Fluid Cooler:
•Water source heat pumps •Cooling special fluids •Condominiums
•Self-contained cooling •Compressor jacket cooling •Steel mills
•Chillers •Machine jacket cooling •Power plants
•Free cooling •Schools
•Hospitals
Q Why would I install a forced draft fluid cooler over other fluid cooler configurations?
AThere are a number of reasons why a forced draft fluid cooler might be the smartest choice:
Low energy and water consumption – forced-draft fluid coolers can alternately operate in a dry cooling
mode if ambient conditions are favorable. This minimizes energy and water consumption, saving money
while conserving natural resources. For situations that require greater electrical energy savings, consider
the Marley MH Fluid Cooler.
Low noise – centrifugal fans and a fully-enclosed falling water area work to create one of the quietest
fluid cooler configurations on the market.
Small footprint – a forced-draft, counterflow design requires considerably less plan area than
crossflow towers.
High static – the capability of centrifugal fans makes it ideal for ducted applications, indoors or out.
Q Can a fluid cooler be used in freezing weather applications?
AYes, but care must be taken to ensure proper operation and orientation (preventing recirculation).
By maintaining sufficient flow rate and heat load on the process fluid, a closed circuit tower can be
utilized in almost any environment.
Fluid exiting the coil must be maintained at or above 7°C. Cycling of the recirculation should not be used
to control process temperatures. Instead, introduction of ethylene or propylene glycol solutions is the best
means to protect the coil. For more severe fluid cooler freezing environments, we recommend the Marley
MH Fluid Cooler.
