ASA offline coolers for oil maintenance
An independent cooling and circulation circuit keeps oil condition stable without loading the main circuit.
ASA offline coolers
ASA recommends offline cooling when oil maintenance is needed aside from the working hydraulics. Solutions include compact air-cooled motor-pump-cooler combinations or water-cooled versions with plate or shell-and-tube heat exchangers.
- Separate from the main hydraulic circuit
- Can combine cooling, filtration and tank conditioning
- Available as compact motor-pump-cooler arrangement

ASA offline coolers
Why use offline cooling?
Because oil can circulate, filter and cool even when the main circuit is idle or variable.
Does offline cooling affect the working hydraulics?
No. It is a separate circuit, making selection and service simpler.
Can filtration be included?
Yes. ASA rail and filter options combine offline cooling with oil maintenance.
