1.9 - Data plate
- Stuck to the rear and front plates
- MANUFACTURING YEAR:Year of manufacture.
- MODEL: for example, PWB 4 11 027H00.
4 = Model.
1 = Number of passes for the hot fluid.
1 = Number of passes for the cold fluid.
027 = Number of plates,
H = Type of plates (H high efficiency, L low efficiency, M mixed).
00 = Proportion of H plates, in % (H00 = 100% H plates, M30 =
30% H plates).
Special case: L00 = 100% L plates.
- DESIGNATION:
- SERIAL No.: Production number, to identify your heat
exchanger.
- DATE: Date of manufacture.
- ALLOWABLE TEMPERATURE MIN. / MAX. (TS): Minimum and
maximum allowable temperatures.
- ALLOWABLE PRESSURE MIN. / MAX. (PS): Minimum and
maximum allowable pressure, in bar.
- TEST PRESSURE (PT): Test pressure, in bar.
- VOLUME: Total capacity of the heat exchanger, in litres.
- 97/23/CE PED CLASSIFICATION: Category of the heat
exchanger (fluid type and group).
- CE: Only for heat exchangers cat. I, II, III and IV. The unit
conforms to the Pressure Equipment Directive (PED 97/23 CE).
This symbol may be followed by the number of the notified body
for category II, III and IV heat exchangers.
- CIRCULATION: 1° indicates the inlet and outlet of the primary
loop. 2° indicates the inlet and outlet of the secondary loop.
- TIGHTENING MEASURE: Minimum and maximum tightening
dimension (A) between the plates, in mm.
2 - STORAGE
- Store the units in a dry room protected from the weather and maintained at a temperature of b5°C and +60°C.
Make sure that they do not touch any walls or each other or are in direct contact with the floor. Protect them against impacts and
make sure that nothing is placed on them.
- The heat exchangers must be placed on blocks that have been adjusted to ensure good stability and levelness. The floor should
be protected from collapsing.
- Do not remove the sealing gaskets on the ends of the pipes until you are ready to make the hydraulic connections.
- All unused spare parts must be stored away from humidity, light, and dust, and protected from impacts.
- Gaskets and plates must be stored in a cardboard box at a temperature of between 10°C and 30°C. Maximum storage time: 6
to 12 months.
