Arctic Fox

In 2011 Powerscreen partnered with Arctic Fox to provide cold weather kits for machines due to work in especially cold environments.

The add-on kits are provided for two temperature levels. The first kit includes an engine pre-heater for machine operation at temperatures as low as -25°C (-13°F). The second enables operations at -40°C (-40°F) and has the engine pre-heater in addition to a kit for engine and hydraulic oils.

Several Powerscreen machines have been equipped with the cold weather kit to date, with more scheduled in the coming months. The existing machines are working in Mongolia, Russia and Kyrgyzstan in desert-like conditions where temperatures have reached -40°C (-40°F).
