Espar D4L Airtronic M3 diesel heater kit for van conversion 12V with Easystart Pro
The Espar Airtronic D4L (M3 generation) delivers a maximum of 4 kW (≈ 13,650 BTU) of clean, dry heat—perfect for Sprinters, Transits, ProMasters, and similar builds. It’s engineered for reliable performance in extreme conditions—even high altitudes up to 9,900 ft (3,000 m)—without requiring an altitude kit, thanks to its automatic adjustment.
Why it Stands Out:
- Low-noise operation: Features a brushless fan and quieter fuel pump that help reduce distracting clicks during sleep or rest compared to the Webasto equivalent.
- Smart temperature control: Includes integrated temperature and altitude sensors and the EasyStart Pro controller with built‑in diagnostics and timer function.
- Flexible ducting: Supports up to 4 duct outlets and approximately 15 m (49 ft) of ducting for truly customized layouts.
Features:
- 4 kW heating power – great for medium to large vans
- Works up to 3,000m (9,850 ft) – no altitude kit needed
- Fuel-efficient – uses only 0.11 to 0.51 L/h
- Quiet and compact
- Easy to install – complete kit included
- Runs off your van’s diesel tank
Perfect for winter road trips, full-time vanlife, or anyone who needs a reliable heat source on the road.
Installation available in the greater Montreal area, QC.
