In addition to worldwide availability, it was important for us to deliver a complete, industrial-quality plant ready for connection. The Engine Air Cooling Unit is manufactured from highest quality materials and guarantees maximum reliability and durability. All relevant components are made of stainless steel or rust-free material.

quality control

Every Engine Air Cooling Unit that leaves our factory is extensively tested on our in-house test bench. You can therefore be sure that you will always receive a fully efficient unit for your test lab.


The Engine Air Cooling Unit was developed according to the ASTM standards:
D2699 - Research Octane Number
D2700 - Engine Octane Number.

The centerpiece of the Engine Air Cooling Unit is the built-in glycol cooler. The unit, which can be replaced in no time at all, cools the refrigerant to the desired temperature and pumps it through the climate chamber and the carburettor bracket.

The closed system is made completely of stainless steel and has an optical fi lling level indicator. The integrated agitator motor on the pump produces perfect mixing of the glycol and prevents temperature stratifi cation and thus measurement errors in the glycol bath.

The thermostatic refrigerant injection via E-valve ensures precise temperature control and thus prevents overshooting around the setpoint. With the Engine Air Cooling Unit, you can always be sure of optimum conditions for your test lab.
