Challenges for Gas Turbines in Snow & Ice Environments

Understanding the air quality challenges that can lower gas turbine and compressor performance in arctic locations or areas with harsh winters and how to remedy these challenges to maximize efficiency and profitability.

Overview - Snow & Ice-min

In sub-zero or arctic climates, snow and ice are the biggest hazards.

Snow and ice can often covering the outer surface of the filter elements and significantly reduce the airflow. This in turn causes high pressure drop, resulting in gas turbine power output deterioration or a unit trip.

Worse still, ice formed in the gas turbine inlet can be ingested into the engine, this may result in foreign object damage and can ultimately result in the subsequent failure of the gas turbine.


Anti-ice systems heat the intake air to eliminate the problems associated with snow and ice.

This can be achieved in several different ways and AAF can design and supply a system to suit an individual installation.

In addition, pulse filters have an anti-ice function that removes the outer layer of snow and ice on the filters when it begins to form. This will avoid differential pressure spiking, lower operating costs, and avoid costly downtime.
