HEaT ExCHangErS
Multiple Heat Exchangers in Series
- Able to extend the thermal length (capacity) of a
heat exchanger.
- Generally a high pressure drop occurs through
the heat exchangers
Multiple Heat Exchangers in Parallel
- Able to handle large flow rates with smaller
sized heat exchangers.
- Can maintain lower pressure drops through the
heat exchangers with larger flow rates.
SoldErIng and WEldIng ConnECTIonS
Soldering Procedures:
Recommended solder material: 30 - 55% silver alloy
Recommended flux material: Black flux for silver soldering
1. Degrease and clean the soldering surfaces on
the piping and the heat exchanger connections.
2. Apply the flux to both surfaces.
3. For refrigerant applications, purge using dry
nitrogen gas on the refrigerant side to prevent
internal oxidation.
4. Heat the soldering area to approximately 1200ºF
(650ºC). Use a wet cloth to protect the heat-
exchanger while brazing.
do not heat the soldering area higher than 1200ºf.
damage to the heat exchanger brazing material
could occur.
5. Keep the piping in a fixed position and apply the
solder.
