The Espar Airtronic AS3 D2L VDP Heater Kit perfectly combines price, performance, and reliability. It provides a 2.2KW / 7500 BTU maximum output with a record-breaking 5,000-hour lifespan.
The AS3 D2L is an all-weather heater that functions in temperatures as low as -51°F / -46°C and at altitudes up to 4000m/13,120ft, while the EasyStart Pro controller makes altitude adjustments automatically.
The S3 D2L VDP (Pressure-Resistant metering fuel Pump) Model is engineered for dependable performance in fuel systems with inlet pressures ranging from 0.7 to 2.5 bar. This self-regulating metering pump ensures accurate fuel delivery, even when connected to pressurized fuel lines. It is ideal for:
Unlike standard S3 D2L models, which are rated for up to 0.4 bar, the VDP pump can withstand pressures up to 2.5 bar, offering enhanced flexibility and performance in both pressurized and non-pressurized systems.
Key benefits:
The new S3 can be tilted by max. 30° (downwards flow direction!) or turned to either side by max. 90° around its own longitudinal axis.
The VDP Inlet Pressure-Resistant Metering Pump operates with fuel inlet pressures from 0.7 to 2.5 bar, self-regulating for accurate fuel metering, even in pressurized systems.
Can operate in extreme conditions, including at high altitudes up to 4,000m and low temperatures.
The Airtronic S3 D2L Heater Kit ticks all the boxes in terms of performance and price. The energy-efficient D2L heater provides 2.2kW / 7500 BTU maximum output.
With AS3, Espar delivered a new smart sensor-controlled starting sequence that allows efficient ignition with a lower current draw. Moreover, the new combustion chamber and dynamic heating control contribute to improved fuel efficiency. Low as 0.06 - 0.28 litres per an hour.
