H4 / H4 Hybrid

 

H2 / Airtronic D2


Air heating unit powered by diesel suitable for small campervans (like Hiace etc.) or smaller up to short wheel base vans (Transit, Crafter, Sprinter). Can be used also for smaller modern caravans with great insulation and double glased windows. This size is suitable for boats up to 10m long.


H4 / Airtronic D4


Air heating unit powered by diesel suitable from mid size motorhomes from long wheel based (Transit, Crafter, Sprinter) up to large horse trucks, buses etc. This size is suitable for boats 8-20 metres long.


H4 Hybrid


Air heating unit powered by diesel that shares exactly the same components as H4. The difference is an additional circuit in the heat exchanger allowing to flow water or any coolant thru the exchanger.


Please note: H4 Hybrid is not an instant hot water system for shower or tap, but rather hybrid air heating solution allowing to distribute the heat via coolant to more remote locations with less heat loss in conjunction with radiators. The water circuit can be also used for preheating the engine coolant. The thermostatic regulation of the power reads the temperature of the air and does not consider the temperature of the coolant.
