Chapter 3: Installation
3-1 Installation Location Considerations
The TC 120 Temperature control systems are portable and can be installed almost anywhere.
As with all equipment installations, follow all applicable codes and regulations.
The recommended ambient temperature range 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.
Provide a minimum of twelve inches (12” or about 30 cm) clearance
on all side of the cabinet to allow circulation of cooling air.
Locate the unit as close to the process as is practical.
3-2 Process Approach Temperature Considerations
If the differential (Δ) 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
All external hose and piping should be adequately sized to assure minimum external
pressure drop.
Low external piping pressure drop is needed for best operation.
Use a backup wrench to support the TC 120 temperature control system piping
when making process piping connections.
All external valves, fittings, and hoses must be rated at a minimum of
150 psig and 250ºF (1,030 kPa/10.3 bar and 121ºC).
The exception is when the temperature control unit
is optionally rated for 300ºF (149ºC) operation;
external valves fittings and hoses must then be rated at a minimum of
150 psig and 300ºF (1,030 kPa/10.3 bar and 121ºC).
3-4 Piping Considerations for Permanent Installations
ACS recommends an optional (or customer-installed) strainer on the
COOLING WATER IN
inlet.
