Product description Product description With this new generation of Universal Hydraulik LKI oil-coolers, the manufacturers have succeeded in reducing the noise level. These coolers are ideally suited for stationary installations - for the cooling of hydraulic or lubricating oils. The range has been extended to include slowrunning ventilators, and the housings have been optimised, in order to produce the very low noise level. In order to make the cooler range as comprehensive as possible, the smaller models are also available as single or dual versions, thus covering oil-cooling requirements for both low and high oil throughflow volumes. The max. oil flow is reduced by 50% in the dual version and the cooler gets a slightly higher performance by this. The oil flow through one half of the cooler and then through the other half in the dual version. The oil stays longer in the cooler, which results in higher performances. The single version is ideal for higher oil volumes, to avoid too big pressure drops on the oil side. You can also see the differences in the performance data and the oil connections on the cooler drawings.

The figures apply to ISO VG32 hydraulic oil with 30 cst. For variances, Δp is multiplied by the correction factor f from the diagram on Page 3.
