Connecting the heat recovery system
➤ Take the electrochemical series into account and choose suitable materials for connections.
➤ Keep the effect of pressure surges on the heat exchanger as low as possible.
➤ Install an expansion tank to act as a pulsation damper if pressure surges cannot be avoided.
➤ Install appropriate regulating devices if the heat transfer medium is to be kept constant.
➤ Avoid very low inlet temperatures of the heat transfer medium as it can cause condensation.
If required, contactKAESER for suitable insulation measures.
WARNING
Cooling oil in the heat-receiving medium!
Oil may contaminate the medium if a leak occurs.
➤ Do not use the heat-receiving medium as drinking water.
➤ Install the heat recovery system in accordance with the following specifications.
