Here are some answers to questions we are often asked. For more detailed information the team at UNEX will be happy to help.
The heat exchanger should be connected in cross-flow, this ensures that
optimal performance can be achieved. Further information can be found in
the relevant manual.
The heat exchanger is best fitted vertically, this helps reduce air and dirt being trapped. Further information can be found in the relevant manual.
This depends on the medium in the heat exchanger. For advice please contact UNEX technical support.
In most systems the air in the heat exchanger will be bled together with the other air in the system.
The guarantee is valid, as long as the heat exchanger has been fitted, used and services according to the relevant fitting, operations and service manual.
Your heat exchanger can be cleaned using a special cleaning material, available from UNEX. We can also clean heat exchangers for you in our workshops.
Welding and other similar processes create very high temperatures, which can damage seals and structure within the heat exchanger. Any work undertaken would invalidate the garauntee.
It is recommended to use mounting brackets. Additional strain on the connections can lead to premature failure and will invalidate the guarantee.
Depending on the operating temperature, insulation prevents heat loss from the heat exchanger and prevents the risk of injury through burns.
Cold leaks can be caused by thermal relaxation in a sealed plate heat
exchanger. As a result, the sealing properties of certain elastomers are
temporarily reduced. Cold leaks occur mainly in older heat exchangers where the
seals have already lost their elasticity.
