Refrigerador de ar industrial AC-LN 8-14 / ACA-LN 8-11 / ACAF-LN 8-11


The AC-LN 8-14 air cooler series can be used in all areas where either oil or water-glycol is to be cooled with air. The coolers with an axial fan can be used in the return line as well as in the bypass flow.

The wide range of accessories and optional versions mean that the coolers can be adapted flexibly to various applications.

Product Features

The air flow of the cooler has been optimized by the use of a more efficient axial fan and a variety of housing modifications. As a result, the AC-LN series 8-14 is especially efficient and quiet.

The cooler can also be used in the bypass flow by attaching a boost pump. An additional filter enables continuous filtration of the medium; the cooler can then be connected as required.
