Chapter 3: Installation
3-1 Installation Location Considerations
Open Resevoir water temperature control systems are portable and can be installed almost
anywhere. As with all equipment installations, follow all applicable codes and regulations.
þ The recommended ambient temperature range for TCU Series installations is
from +14ºF (-10ºC) to a maximum operating ambient temperature of 131°F
(55ºC). Recommended ambient storage temperature range is from -13ºF to 149ºF
(-25ºC to 65ºC). If storing the unit below freezing temperatures, make sure the
unit has an antifreeze mixture circulated inside.
þ Provide a minimum of twelve inches (12” or about 30 cm) clearance on all sides
of the cabinet to allow circulation of cooling air.
þ Locate the unit as close to the process as is practical.
3-2 Process Approach Temperature Considerations
If the differential (r) between COOLING WATER IN and TO PROCESS temperatures is
less than 10°F (7ºC), consult our Sales Department for advice on how to control low
approach applications.
3-3 External Piping Sizing Considerations
þ All external hose and piping should be adequately sized to assure minimum
external pressure drop.
þ Low external piping pressure drop is needed for best operation.
Note: Use a backup wrench to support TCU Series system piping when
making process piping connections.
All external valves, fittings, and hoses must be rated at a minimum of
150 psig and 180°F (1,034.25 kPa/10.34 bars and 82ºC).
3-4 Piping Considerations for Permanent Installations
An optional (or customer-installed) strainer on the COOLING WATER IN inlet is
recommended
Keep restrictions to a minimum by using proper inlet pipe sizing. If the water supply piping is
larger than ¾”, reduce the size at the unit. The table below contains the pipe sizes that are
used in the unit.
