Ensure that the cooling water is softened and free
of chlorides. Any hardness in the cooling water will
result in scale build-up on the coil and a loss of heat
transfer capacity. Chlorides can cause pitting or
stress corrosion in stainless steel. If no source of
acceptable cooling water is available, consult
Solutions Inc for a recommendation.
Ensure that minimum required cooling water flow is
occurring. If cooling water is untreated, its
temperature rise should not exceed 30°F (17°C) in
order to minimize scaling. Be sure that the outlet
temperature does not exceed 140°F (60°C).
When necessary, throttle cooling water by partially
closing the outlet valve on the cooling water outlet
line. Any valve on the cooling water inlet line must
always be fully open during operation.
Safety Note: Sample Flow must be completely
stopped and isolated before disconnecting any
sample cooler from the cooling water head-
ers. Failure to do so could result in damage to
property, injury or death.

Cavitation
Cavitation can cause damage and failure of
equipment.
Cavitation results when localized boiling occurs on
the surface of a coil. Vapor bubbles form on
the coil surface and are swept into the main stream
of the fluid where they immediately
condense and collapse. Collapsing bubbles generate
severe shock waves (i.e., vibrations)
which can fatigue and ultimately fracture the
tube(s).
Cavitation can be avoided by considering the
following:
1. Cavitation is caused by:
a. Coolant flow rate is too low; fluid overheats
to its boiling point.
b. Sample flow rate is too high; coolant overheats to its boiling point.
c. Coolant operating pressure is too low; fluid
boils at a low temperature.
Excessive coolant flow rate can cause vibration of
the coil due the effects of vortex
shedding, leading to coil failure. Reduce coolant
flow rate to design condition. Coolant outlet
temperature should not exceed 140°F. Reduce
sample flow rate as necessary to achieve coolant
flow and temperature limitations.
Maintenance
For heavily scaled coolers, disassembly is made
easier by first dissolving the scale. Remove scale by
circulating an inhibited acid cleaning solution (citric, sulfamic,etc) through the cooling water side.
Replace used gaskets with new ones. After reassembly, pressurive shell and visually inspect for water
leaks. Replace gaskets showing visible leaks. Kepp
spare shell gaskets on hand for this need.
2. Cavitation can be prevented by:
Tighten the bolts. Overtightening can cause gasket
a. Adjusting coolant and sample flow rates.
failure.
b. Increasing coolant pressure as high as SC2.4: 35 ft/lbs S
C3.5/4.7: 45 ft-lbs
possible — 50 psig (3 barg) minimum
recommended for water.
Additional Information
3. If you hear vibration or rattling noises from the
equipment, take corrective action
immediately:
a. Ensure coolant inlet valve is fully open.
b. Ensure coolant flow is per design
condition.
c. Ensure coolant pressure is as high as
possible.
d. Reduce the sample flow rate.
e. Check that the coolant flow rate is throttled
using the outlet valve only, not the inlet. This
ensures that the coolant is at the higher
pressure.
