Oil-air-coolers offer more than just compact heat exchange design and high efficiency – the cooling units and fans fitted are also optimized to ensure that the coolers run with a minimum of noise.
The current range consists of 11 sizes with cooling capacities between 4.4 kW and 140 kW at 40°C inlet temperature differential, with one-pass or two-pass versions of unit sizes 5 to 60 available. Two versions in sizes 5 to 60 are available: one with low pressure drop, the other with high cooling performance.
Our oil-air coolers are constructed on a modular basis, so they are suitable for both static and mobile hydraulic systems. From size ACN-10 IEC standard motors are used, so the coolers can be operated with special voltages.
On request the ACN oil-air cooler from size ACN-10 are also available with a declaration of conformity according ATEX 94/9/EG.
