In modern truck engine compartments, the available space in recent years has been steadily decreasing and accordingly, the demands on the engine cooling system have never been greater. The demands are obvious: Shorter warm-up phases, rapid heating of interior and low fuel consumption must be guaranteed with a longer design life of all components.
The comprehensive product range of Behr Hella Service which contains more than 60,700 applications for commercial vehicles perfectly satisfies these requirements and comprises:
- Coolant radiator,
- Expansion tank,
- Visco® fan,
- Condenser/radiator fan
- Intercooler
- Oil cooler
- Cabin heat exchangers and
- Electrical auxiliary heater
In short - we offer everything you need to maximize the efficiency of the cooling circuit.
The cooling circuit in trucks
The heat produced by the combustion of the engine is absorbed by a coolant consisting of water, antifreeze and additives and is transferred to the external air via the radiator. The components of this cooling circuit are connected by hose lines and constitute a self-contained system in which the radiator assumes the central role, as the coolant is cooled back down here via the ambient air. The all-aluminum radiator which is available from Behr Hella Service and is characterized by lower weight and reduced overall depth and is also 100% recyclable, represents state-of-the-art technology. The coolant flow which is driven by a pump is controlled with reference to temperature using a thermostat. With powerful engines such as those used in trucks, the radiator may also require assistance from special fans, e.g. our Visco® fan, when cooling the engine.
If the cooling circuit is perfectly harmonized, this can have a positive impact on fuel consumption, emissions, driving comfort and driving safety.
