Brand new Eberspacher / Espar Airtronic M2 D4L 24v Air Heater Kit , upgraded Airtronic D4 Plus / D4S 

The cutting-edge M2 Espar D4L sports an upgraded burning chamber, fuel pump, a brushless blower fan, and an integrated altitude sensor for those higher climbs. These upgrades make the Espar D4L significantly more durable with a 5000 hour lifespan. The heater is noticeably quieter, more fuel-efficient, and can operate at altitudes up 9,800 feet.

This kit doesn't include the EasyStart Pro Controller, which is highly recommended with the Espar D4L. This controller gives you full control over the brushless motor, with stepless adjustment to the heat output of the heater. It also gives accurate information about the heater and provides easy-to-read fault codes in the case of an error.
