Polar GSH-N400 is a completely new aircraft heater. The design of the heater is based on our existing civilian and military aircraft heater models of which our customers have years of experience in harsh conditions.

We have used this vast experience and combined the best features of our old models to design the new GSH-N400. Furthermore, we have collected our customers’ ideas of the features they’d want to see in aircraft heaters in the future and tried to enable these features in the new model.
