Ice accumulating on the filter elements will block the filter and lead to loss of power through a drop of pressure and reduced mass flow. In extreme cases, chunks of ice may be ingested into the compressor and cause physical damage to the turbine.

Carefully monitoring the ambient temperature and relative humidity enables operators to use heating systems effectively and efficiently.

Where the relative humidity of the air is often more than 80 %rh, dense fog is likely to form. In these conditions, when the ambient temperature drops to below 5 °C ice may start to form.

Effectively protecting against damage from ice is important and has an extremely low cost-to-value ratio. Employing a chilled-mirror-based system can protect the operator from costly turbine damage and failures.
