Shell/Tube Heat Exchanger Installation
The satisfactory use of the heat exchanger equipment is depend upon precautions which must be taken at the
time of the installation.
1. Connect and circulate the hot fluid in the shell side (over small tubes) and the cooling water in the tube side
(inside the small tubes). Note piping diagrams.
2. If an automatic water regulating valve is used, place it on the INLET connection of the cooler. Arrange the
water outlet piping so that the exchanger remains flooded with water, but at little or no pressure. The
temperature probe is placed in the hydraulic reservoir to sense a system temperature rise. Write the factory
for water regulating valve recommendations.
3. There are normally no restrictions as to how this cooler may be mounted. The only limitation regarding the
mounting of this equipment is the possibility of having to drain either the water or the fluid chambers after the
cooler has been installed. Both fluid drain plugs should be located on the bottom of the cooler to accomplish
the draining of the fluids. Drains are on most models.
4. It is possible to protect your cooler from high flow and pressure surges of hot fluid by installing a fast-acting
relief valve in the inlet line to the cooler.
5. It is recommended that water strainers be installed ahead of this cooler when the source of cooling water is
from other than a municipal water supply. Dirt and debris can plug the water passages very quickly,
rendering the cooler ineffective. Write the factory for water strainer recommendation.
6. Fixed bundle heat exchangers are generally not recommended for steam service. For steam applications, a
floating bundle exchanger is required.
When installing floating bundle unit, secure one end firmly and opposite end loosely to
allow bundle to expand and contract. Consult factory for selection assistance.
7. Piping must be properly supported to prevent excess strain on the heat exchanger ports. If excessive
vibration is present, the use of shock absorbing mounts and flexible connectors is recommended.
