Thompson Pump Arctic Knight cold-weather package

The Arctic Knight from Thompson Pump & Manufacturing is a cold-weather package that allows diesel-powered pumps to be used in climates as cold as minus 40F. The Arctic Knight uses a self-contained, thermostatically controlled heating system that operates from the on-board fuel supply to regulate the temperature inside the pump enclosure. To prevent liquids from freezing when the pump is off, an auto-drain feature drains fluid from inside the pump and piping system. This system requires no external electric power to operate, and a powerful drain valve prevents debris from interfering with closure.
