Are you wishing to purchase the now old generation Eberspacher D4 Airtronic heater only? Eg, do you have existing heaters that you are hoping to replace with identical model?
or is your enquiry regarding full new Eberspacher 4kw heater + installation sets to fit into new applications? 12v or 24v?
Regarding point 1 above – the older generation D4 Airtronic has been replaced by 2 more recent versions. Occasionally we are able to purchase this heater from European suppliers as there still just a very few manufactured to fulfil longstanding contracts by Eberspacher… military, blue light brigades etc
point 2 above – the latest generation is named M3 D4 Airtronic, very popular heaters that we supply and ship daily to customers. We also have upgrade packages and adapter wiring harnesses to allow M3 D4R heaters to act as ‘drop-in’ replacements for the older D4 Airtronic heaters
