Installation
The Sentry W9000 Series sample cooler is provided with 1/4" NPT connections for
sample fluid and 3/8" NPT connections for cooling water.
Use 3/8" fitting for cooling water only. Never connect hot or high pressure samples to the
3/8" fitting as injury or damage to equipment can result.
The sample cooler should be installed in the vertical position. The direction of
flow(s) are indicated on the permanently attached label located on the coil shell.
Proper installation requires valves on sample inlet and cooling water inlet for hot
water service. An additional valve must be installed on the sample outlet for all
vapor or steam to obtain required operating pressures in the coil.
Proper installation in the superheated steam service also requires pre-cooling
the sample to 750°F, the maximum design operating temperature on the sample
cooler. Pre-cooling can be accomplished by installing a pipe between the main
steam header and the sample cooler to radiate excess heat. The length of the pipe
is determined by the chart at the bottom right-hand side of page.
Operating Conditions
The cooling water should have a constant temperature and flow at a constant,
uninterrupted rate. In order to prevent the formation of mineral deposits in the
shell, softened water is recommended; otherwise, periodic acid cleaning will be
necessary.
Operation
To start up, open cooling water valve "A" to normalize the temperature of the
cooler prior to starting the sample flow. With valve "C" closed, open valve "B". Then,
open valve "C" until desired sample temperature is achieved. Sample temperature
will be dependent upon the temperature of the cooling water and the amount of
sample produced. If sufficient quality of sample cannot be produced at the desired
temperature, a larger cooler or two coolers in series may be required.
To place in service:
To remove from service:
Open valve "A"
Close valve "B"
Open valve "B"
Close valve "A"
REMEMBER: Cooling water on before sample on. Sample off before cooling water
off.
Operating cooler without cooling water can result in damage to the cooler or injury to
the operator.
Performance
Assuming a coolant inlet of approximately 55°F (12°C) and exit of 120°F (50°C)
and a sample exit of approximately 110°F (43°C), the cooler will perform at
approximately the ranges described:
Hot Water Samples
ƒ
At 250°F (120°C), approximately 1500 cc/min of sample will be produced using
1 gallon per minute of coolant.
At 700°F (370°C), approximately 950 cc/min of sample will be produced using
ƒ
2.5 gallon per minute of coolant.
Saturated Steam Vapor
The sample inlet and exit valves can be used to create various operating pressures
in the cooler in order to produce samples from saturated steam vapor.
At 175 psia operating pressure, 640 cc/min of sample can be produced using
ƒ
approximately 3 gallons per minute of coolant.
ƒ
At 25 psia operating pressure, 300 cc/min of sample can be produced using
approximately 1.5 gallons per minute of coolant.
