Brazed Plate Heat Exchangers Installation, Operation, and Maintenance Manual 6
WARNING:
Many heat exchangers circulate fluids which are irritating or dangerous to
the human system. These fluids could cause problems if bolted or
threaded joints are not maintained in a leak tight condition at operating
pressures, temperatures, an no flow, ambient conditions.
CAUTION:
Even if fluids are not irritating or dangerous, a leak could cause a slippery
situation on the floor below.
CAUTION:
Since one fluid in the heat exchanger is at a higher temperature, any leaks
may cause burns.
CAUTION:
Brazed plate heat exchangers have exposed sharp metal surfaces.
Protective gloves are recommended during handling.
1. Upon receipt of the exchanger, inspect for shipping damage, especially to the connections. If
damage is extensive, notify the carrier immediately. Finally, check the heat exchanger against
proper drawings and spec sheets to make sure everything is as expected.
2. Before piping up, inspect all openings in the heat exchanger for foreign material. Remove all plugs
and shipping covers immediately prior to installing. Make sure it is thoroughly cleaned to remove
all preservation materials, if any were used, unless the material is soluble in the system fluid.
3. For single phase fluids, the heat exchanger can be mounted in any orientation that is convenient
and should be piped in a counter current, parallel flow arrangement. For two phase fluids, the heat
exchanger should be mounted vertically and piped as shown in Figure 1 and Table 1. Connections
may be either on the front or back of the exchanger.
