4.0 INSTALLATION
4.1 Location
The heat exchanger should be installed in an area with
adequate clearance around the unit to install or
remove plates and perform maintenance.
The unit should also be located with consideration for
the required piping connections. Product and service
lines should be designed to minimize pressure drops
and be adequately supported to minimize the loads on
the heat exchanger.
4.2 Foundations
The foundation pad for the heat exchanger should be
level and sized properly for the outline of the frame. It
must also be of adequate strength to support the full
operating weight of the unit. The overall dimensions
and operating weight are listed on the general
arrangement drawing.
4.3 Space Requirements
On at least one side of the plate heat exchanger there
must be sufficient clearance to remove a plate from
the top bar. Also, there must be adequate room to
tighten or remove the tie bars and inspect the plate
heat exchanger
(Figure 15 ) . The follower must be
free to move along the full length of the top bar as
shown in
(Figure 16) . The general arrangement
drawing provides overall dimensions and plate
removal distance.
4.4
Connections and Piping
The plate heat exchanger must be connected in
accordance with the arrangement shown on the
general arrangement drawing provided with the heat
exchanger.
Pipe lines to the follower and connector grid(s) must
be located to allow the unit to be easily opened for
inspection and maintenance. These lines must also
be flexible to allow for small variations in the tightening
dimensions and possible thermal expansion.
4.5 Pressure Pulsation and Vibration
Piston pumps, gear pumps, valves etc. must not be
able to transfer pressure pulsations or vibrations to the
plate heat exchanger as this may cause fatigue
fracture in the plates. The use of pressure dampers in
the pipeline is recommended to minimize this effect.
4.6 Pressure / Temperature Ratings
The pressure and temperature ratings for a specific
heat exchanger are listed on the general arrangement
drawing provided with the unit. These ratings must not
be exceeded at any time during startup or operation.
Over pressure protection must be provided if it is
possible the system may develop a higher pressure
than the maximum allowable working pressure of the
heat exchanger.
