General Safety Precautions
Product Selection, Installation, and Use
Improper selection, installation, or use can cause personal injury or property damage.
It is solely the responsibility of users, through their own analysis and testing, to select
products suitable for their specific application requirements, ensure they are properly
maintained, and limit their use to their intended purpose.
Follow proper local, state, and federal regulations for proper installation and operational
requirements.
Always use caution and common sense when working with any chemical. Read
the product label and Material Safety Data Sheets (MSDS) carefully and follow the
instructions exactly.
Potential Equipment Hazards
Hot surfaces! This equipment may have very hot
surfaces. If an operator contacts a hot surface, injury
may occur. Use protective clothing to prevent injury.
If other equipment comes in contact with a hot
surface, damage to the equipment may occur. Ensure
the area around this equipment is kept clear to
prevent this damage from occurring.
High pressures! This equipment may contain fluids
at very high pressures. Prior to installing, removing,
or maintaining this equipment, ensure that the
equipment is isolated from all connecting piping, the
equipment is depressurized, the contents have been
drained, and the equipment is cool.
Freezing Temperatures! This equipment may have
very cold surfaces. If an operator contacts a cold
surface, injury may occur. Use protective clothing to
prevent injury. If other equipment comes in contact
with a cold surface, damage to the equipment may
occur. Ensure the area around this equipment is kept
clear to prevent this damage from occurring.
Freezing of fluids in tube
can lead to rupture of the
tube wall and coil failures.
Take precautions to avoid
freezing, such as draining
the equipment when out
of service or installing the
equipment in an environment
protected from temperatures
below the freezing point of
the fluids used.

VIBRATION is the typical cause of Sample Cooler failure.
VIBRATION is caused by two (2) conditions:
A. CAVITATION RESULTS whenever localized boiling occurs on the outside surface
of the hot heat transfer coil. Steam bubbles form on the shell side of the hot
coil surface and are swept into the main stream of the cooling water, where
they immediately condense and collapse. The collapsing bubbles generate
severe shock waves (i.e. vibrations) which can fatigue and ultimately fracture
the heat transfer coil.
CAVITATION IS CAUSED BY: (a) the cooling water FLOW RATE IS TOO LOW,
such that the water is OVERHEATED to its boiling point, and/or (b) the cooling
water OPERATING PRESSURE IS TOO LOW, such that the cooling water can
BOIL at too low a temperature.
CAVITATION CAN BE PREVENTED if (a) the cooling water and sample ows
are kept at the design conditions specied in WATERS literature, and (b)
the cooling water pressure is kept as high as possible (50 psig minimum
recommended). To avoid reducing the cooling water pressure in the shell side,
do any throttling at the cooling water OUTLET, never at the INLET.
B. EXCESSIVE COOLING WATER VELOCITY will vibrate the heat transfer coil, which
can fatigue and ultimately fracture the coil. To prevent coil failure, keep the
cooling water ow at the design conditions specied in WATERS literature.
REMEMBER: Throttling must be done at the cooling water OUTLET.
IF YOU HEAR VIBRATION OR RATTLING NOISES from the cooler, take corrective
action IMMEDIATELY to:
Eliminate vibration from cavitation by adjusting cooler so that:
a. Cooling water inlet valve is fully open.
b. Cooling water ow is per design condition.
c. Cooling water shell side pressure is as high as possible.
d. Sample ow is reduced if necessary.
Eliminate vibration from excessive velocity by throttling cooling water
ow to design conditions. Always throttle at the cooling water outlet.
Installation
1. Support the Waters Equipment W9150/W9250 Series sample cooler by its
bracket or by water lines only.
2. Provide a globe valve (not gate) in the COOLING WATER OUTLET LINE for
throttling purposes. (3/8" for Model W9000, ½" for Model W9100 series; ¾" for
Model W9200 series)
3. If it’s desired to isolate the cooler, provide a ¾" gate or ball valve (not globe) in
the COOLING WATER INLET line.
4. For shell side pressure relief, install a combination temperature/pressure relief
valve in the COOLING WATER INLET line.
5. Mount the cooler vertically.
6. Make connections to the cooling water connection and sample uid studs by
means of welding or with ttings, as appropriate.
Start-up and Operation
1. Open fully all cooling water lines. Verify that minimum specied cooling water
ow is occurring. If cooling water is untreated, its temperature rise should not
exceed 40°F, so as to minimize scaling.
2. When necessary, throttle cooling water ow by partially closing the globe
valve on the COOLING WATER OUTLET line. Any valve on the COOLING
WATER INLET must always be full open.
3. When possible and practical, shut o the sample uid when not taking a
sample so as to minimize scaling. This action is not necessary if the cooling
water is from a treated, closed loop supply.
Disassembly and Reassembly
1. For heavily scaled coolers, disassembly is easier by rst dissolving the scale.
Remove scale by circulating an oxalic acid cleaning solution through the
cooling water side.
2. Reuse original gaskets if not too old or if not overly compressed. After
reassembly, pressurize shell and visually inspect for water leaks. Replace those
gaskets that show visible leaks. Keep spare shell gaskets on hand for this need.
