IV. OPERATING PARAMETERS & SELECTION OF HEAT

Standard maximum working parameters of the heat exchangers are as follows:

Regardless of the application, proper sizing of a heat exchanger is extremely important in ob-

taining the desired thermal performance from the unit. In order to select the most appropriate

product for an application, a customer should specify the following information:

- type of operating medium/fluids

- required heat load

- required inlet/outlet temperatures of the heating medium required inlet/outlet temperatures

- of the heated medium

Selection is made through an internally developed software program and distributed to our

customers.

V. INSTALLATION

Before installing the heat exchanger into the system, ensure that all the proper piping and

safety gauges are in place:

Allow enough space around the heat exchanger to provide sufficient clearance to permit

the removal of the tube bundle from the shell (for maintenance or inspection purposes).

Provide valves and bypasses in the piping system so that both the shell side and tube side

may be bypassed to pennit isolation of the heat exchanger for inspection, cleaning, and repairs.

Provide thermometer wells and pressure gauge pipe taps in all piping to and from the heat

exchanger, as close as possible to the unit to detect operating performance of the unit.

Provide necessary air vent valves for the heat exchanger so that it can be purged to

prevent or relieve vapor or gas binding on both the shell and tube side.

Install proper liquid level controls and relieve valves and liquid level and temperature

alanns, etc.

Install a surge drum upstream from the heat exchanger to guard against pulsation of

fluids caused by pumps, compressors, or other equipment.
