Hydac Oil / Air Cooler Units AC-LN MI Low Noise Series

HYDAC Oil / Air Cooler Units AC-LN MI Low Noise Series

The integrated frequency inverter controls the fan speed depending on the fluid temperature. This way fluid temperature keep a constant level with less energy consumption and less noise

AC-LN MI coolers use high efficiency axial fans driven by a frequency inverter. This guarantees immediate adjustment to required cooling performance under changing load conditions

Variable speed
The inverter controls the fan speed in order to have a constant temperature

Plug and Play
Simple installation thanks to the integrated frequency inverter and temperature probe

Lower operating cost
The electric power is required only when cooling power is needed allowing lower power consumption

Lower average noise level
When less power is required the cooler generates less noise

PT1000 Temperature probe with probe holder
Accurate and reliable temperature measurement, no need to drain the cooling system when probe replacement is needed

Fail-Safe operation
Operation at maximum speed in case of Probe failure detection (open or short circuit)

Own safety
If during operation the electronic overheats, fan speed drops automatically

Software interface
A user friendly interface is available to check and modify all the parameters directly on site

Typical Applications include systems with high cooling requirements in return line and off line, such as:

• Hydraulic systems
• Lubrication systems
• Gears
• Motors
• Generators
• Converters
• Machine tools

Efficient cooling systems can help to lengthen the service life of the operating fluids and filters used and reduce life cycle costs
