Planned preventative maintenance

Periodic manual checks are essential to ensure the accuracy and functionality of your district energy network, and it will save you money in the long run.

A district energy network needs regularly planned preventative maintenance and inspection to ensure that the life of the system is maximized and that the risk of failure through neglect is mitigated.

There are primarily two ways a network can fail. First, the network carrier pipe can fail due to poor water quality. A network alarm system will alert you of the failure once it has occurred, but by then the damage is already done and the repair cost can be significant. The optimal way to prevent this problem is to ensure that the quality of the water in the system is maintained and monitored on a permanent basis. Second, failure from external damage to the outer casing can occur, and if it is left unattended, this can result in failure of the inner carrier pipe due to moisture penetration. Regular planned inspection of the integrated alarm system can prevent these system failures and detect ingress of water into the insulating foam.

To provide customers with the knowledge that their networks are being maintained and protected properly isoplus now provide an option to enter into a planned preventative maintenance service contract.


How can isoplus help?

The details of the specific operation and maintenance contract can be customized to fit the needs of each customer, but outlined below are the areas that can be provided:

  • Six monthly visits to visually check for signs of corrosion to termination points where the network leaves the ground
  • Six monthly operation and reporting of network isolation valves

  • Six monthly detailed inspection reports and repair recommendations
  • Access to call out facilities should failure occur on the network
