Frequently Asked Questions
| Here are some answers to questions we are often asked. For more detailed information the team at UNEX will be happy to help. |
| Q: | How should the heat exchanger be connected? |
| A: | 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. |
| Q: | In which position should the heat exchanger be fitted? |
| A: | The heat exchanger is best fitted vertically, this helps reduce air and dirt being trapped. Further information can be found in the relevant manual. |
| Q: | Which sealing materials should I use? |
| A: | This depends on the medium in the heat exchanger. For advice please contact UNEX technical support. |
| Q: | Does the air need to be specially bled from the heat exchanger? |
| A: | In most systems the air in the heat exchanger will be bled together with the other air in the system. |
| Q: | Is the guarantee still valid once the heat exchanger has been built into a system? |
| A: | 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. |
| Q: | How can I clean my heat exchanger? |
| A: | 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. |
| Q: | Can I weld anything to my heat exchanger? |
| A: | 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. |
| Q: | Do I need to fit a mounting bracket, or will the connections support the heat exchanger? |
| A: | It is recommended to use mounting brackets. Additional strain on the connections can lead to premature failure and will invalidate the guarantee. |
| Q: | Does the heat exchanger really need insulation? |
| A: | Depending on the operating temperature, insulation prevents heat loss from the heat exchanger and prevents the risk of injury through burns. |
