The Automotive Aftermarket division of industrial and
automotive supplier Schaeffler is expanding its range of thermal management
modules under the INA brand. Schaeffler has been series supplier in many
vehicles since 2011 with its first-generation thermal management module.
In close partnership with automotive manufacturers,
Schaeffler develops thermal management modules that are capable of controlling
the coolant temperature in various cooling circuits as required. This enables
the engine to reach its optimum operating temperature more quickly. Driving
comfort is increased, and fuel consumption and CO2 emissions are reduced. Over the years, the module has been consistently
developed. The second generation is now sold exclusively by Schaeffler in the
independent aftermarket as a complete repair solution.
The second generation of thermal management modules is
still based on rotary slide valves that control the coolant flow depending on
the driving situation. However, the new actuator concept with two independent
rotary slide valves achieves significant improvements in functionality. While
one valve is responsible for controlling the flow of coolant to and from the
radiator, the other is responsible for separating the engine cooling circuits
in the cylinder head and block. This makes it possible to implement a so-called
The concept meets the increased demands placed on the
engine in start-stop or hybrid operation and ensures optimum temperature
control of the cylinder head and block through more targeted cooling.
Frictional power in the combustion chambers significantly reduces when
switching from pure electric mode or longer resting phases during start-stop
operation. This leads to optimised combustion, reduced wear and lower CO2
"Thermal management plays a central role in
improving energy efficiency and reducing CO2 emissions of vehicles. Fine-tuned,
intelligent control of increasingly complex cooling and heating circuits
ensures that all relevant systems operate within the optimum temperature range
at all times. This protects the environment and at the same time increases the
service life of the components. In line with development of the global car
parc, we are constantly developing our thermal management product range. We are
proud to be the first supplier in the aftermarket to offer this repair solution
for hybrid vehicles," explains Maik Evers, Head of Product Management at
Schaeffler Automotive Aftermarket.
Previously, Schaeffler exclusively offered the thermal
management module for VW Group vehicles in the independent aftermarket. The
range has now been extended to include two-part numbers for BMW and MINI
engines: part number 538 0810 10 for 3- and 4-cylinder engines (B38 and B48)
and part number 538 0811 10 for 6-cylinder engines (B58). These two-part
numbers already cover a car parc of more than two million vehicles, which is
set to double in the next three years.
