Integrated heat exchangers
HTX 3.3 – 6.6 kW

Efficient use of engine waste heat

The HTX series of integrated heat exchangers from Webasto offers various models with heating outputs between 3.3 and 6.6 kW. The waste heat from the running engine reaches the heat exchanger via the coolant circuit, where it is transferred to the air in the vehicle. Thanks to various installation positions and an extensive range of accessories, the devices can be flexibly integrated into camping and special vehicles as well as construction and agricultural machinery and boats. Durable, highly efficient fans and blowers ensure a strong and constant air flow and therefore optimum air distribution in the vehicle.
