Attention: Make sure that the BPHE is not exposed to severe vibration or pulsation. To
avoid that, vibration absorbers (e.g. mufflers) must be installed in pipework system, or
between the BPHE and other equipment must be vibration-absorbing material. The BPHE
lifetime will be significantly reduced, if there is insufficient system and flow control. The
following are some of the factors that have adverse effect on the life of the product.
The following impact should be avoided:

Excessive control valves;

Excessive pressure variations in the different channels of the system;

Poor quality control valves;

Improper controller settings.
Attention: Before connecting BPHE to new or renovated pipework systems, you have to
ensure that pipework is free from garbage and/or course particles which could clog the BPHE
fluid channels. To increase the safety of operation of the BPHE the installation of filters on
the entrance of the mediums is recommended, to prevent the getting into the channels of
small particles.
5. Installation using solder (sweat), welding and threaded
connections.
Soldered (sweat) connections
Clean and degrease the solder surfaces (both – on
the copper pipes and on the BPHE connectors).
Polish the surface to remove oxides. Solder the
surfaces. To prevent oxidation during soldering
process, fill the inside of the BPHE with nitrogen. Point
the flame towards the connectors.
Do not point the soldering equipment’s flame
against the BPHE, do not exceed soldering process
temperature higher than 650°C (1200°F). Soldering
material: with silver content not less than 45%. Use a
wet cloth (1) to prevent overheating of the BPHE. Make
sure the BPHE and tubes stay static during soldering
process.
Warning: excessive heat can lead to copper melting
while damaging the BPHE.
Welded connections
Use TIG (GTAW) welding.
Use a wet cloth (1) to prevent overheating of the
BPHE.
