Air Handling Unit Coil Replacement

Air Handling Unit Coil Replacement

The coils in an air handling unit are usually used to achieve the treatment of air such as heating, cooling or dehumidification.

Coil replacement can be due to the following reasons:

Damage to the coil: e.g., cracks, leaks, etc., which affect its normal heat exchange function.

For example, long-term corrosion may cause the coil walls to thin and break, necessitating replacement.

Performance degradation: After a long period of use, the heat exchange efficiency of the coil decreases and fails to meet the requirements of air treatment.

For example, there is a heavy build-up of dirt on the surface of the coil, which hinders heat transfer.

Mismatch of specifications: When the system requirements change, the original coil specifications are no longer suitable and need to be replaced with a more appropriate model.

When performing AHU coil replacement, the following points need to be noted:

Select the appropriate coil model and specifications to ensure compatibility with the AHU system and to meet the capacity and performance requirements of the treated air.

Replacement operation should be carried out by professional technicians to ensure correct installation and sealing.

After replacement, the AHU system needs to be debugged and tested to ensure that it operates properly and performs up to standard.
