1. Cooling capacity is based in a 10°C difference between the temperature of the cooling
water supply and the cooling fluid flowing from the System III
to the instrument being cooled (see
Section III, acility Water Requirements). Pressure drop obtained with the System III modulating
valve fully open.
2. Larger volume reservoir units are available.
3. Units with CP-55 and TU-3 pumps. Other larger volume units measure 33¾ x 23 x 27¼

Section III Installation
Site
The unit should be located in a laboratory or clean industrial environment with
easy access to a facility cooling water supply and a drain. Never place the unit
in a location where excessive heat, moisture, or corrosive materials are
present.
Refer to the pump label on the rear of the unit to identify the specific type of
pump in your unit. Units with a TU-7, TU-8 or TU-9 pump are equipped with a
pump motor fan. The fan is used to cool the pump motor and prevent the motor
from overheating. Air is drawn through the front of the unit and is discharged
through the rear of the unit. A minimum clearance of 6 inches (0.15 meters) at
the front and rear of the unit is necessary for ventilation.
Facility Water
Req irements
Limit the facility water inlet pressure to less than 150 psi (10,2 Bar) and
limit the facility water inlet pressure to outlet pressure differential
across the System III to less than 35 psid (2,4 Bar).
Refer to the Cooling Capacity chart in Section II, Specifications. The flow rate of
the cooling water supply must meet or exceed these requirements for the unit
to operate at its full rated capacity. If the cooling water does not meet these
standards, the cooling capacity will be derated. The chart is based on a
difference between the temperature of the cooling water supply (House Water)
and the cooling fluid flowing from the System III to the instrument being cooled.
As the heat load increases, the required flow rate of the cooling water supply
increases. For example, on a System III with a 6 gpm pump flow, if the heat
load is 12 kilowatts, approximately 3 gpm of cooling water flow is required to
remove the heat. However, if the heat load is increased to 36 kilowatts, about 8
gpm of cooling water flow is required.
The flow meter on the front of the unit does not measure the flow rate of the
cooling water supply. The flow meter measures the flow rate of the cooling
fluid returning to the instrument being cooled.
