Oil and water conditioning units

for combustion engine test benches

To achieve accurate and reproducible measurements on a combustion engine test bench, constant temperatures of the supply media are, amongst others, an indispensable prerequisite.
It must be ensured that the temperature of the supply media at steady state is kept at +/- 1 K.
Precisely for these and also other tasks the conditioning units of LEW Automotive are designed and developed with years of experience to the present state. Due to the modular design of the conditioning units in the construction and function, they can be combined and individually adapted to the specific task.
Both stationary units for wall and raised floor mounting and mobile units for flexible use are available.

Denomination of the conditioning units:

  • MK = engine water conditioning unit
  • OK = engine oil conditioning unit
  • KKM = combination cooler module conditioning unit


-->   high control accuracy

Your benefit !

-->   defined and constant temperatures of the supply media

-->   modular design

-->   short installation and commissioning times
-->   wall and raised floor mounting possible
-->   different options:
       - preparation for connecting a
         cold shock device
       - shortening the warm-up phase of the engine
         by installing a heating system
       - cooling water regulation to save
         the cooling water quantity provided by the customer

-->   stationary or mobile

-->   user-friendly

-->   compact design

-->   individual construction
       adapted to the locations
-->   quickly changeable operating parameters by
       integrated cabinet
       if realized in in mobile design
-->   easy integration into
       test bench automation system
-->   space-saving due to variable dimensions
