BMW 3-Series A/C Evaporators & Components

An evaporator is a small radiator located in or under the dashboard, and it is that very component of the A/C system that actually cools the cabin. When the refrigerant reaches the evaporator, it has already been cooled down in the condenser, and it is ready to absorb the excessive heat from the cab. In the meantime, the blower fan blows air through the evaporator, circulating cold air inside the car, while the refrigerant quickly reaches its boiling point and transforms from liquid into vapor, getting ready for another refrigeration cycle. The BMW 3-Series features a premium A/C system, as expected from the German maker, yet some issues related to evaporator leaks have been reported.

Usually evaporators are made from aluminum and look like radiators, just being smaller in size: it is a thick net of thin tubes where the refrigerant is cooled. Problems affecting evaporators are mainly related to leakages due to corrosion - organic materials sucked from the air intake can possibly start the process. In this case, installing a new evaporator is recommended, and you can find it at our online shop, where a vast choice of BMW 3-Series A/C evaporators and components is available.
