Heat Exchangers – Oil-Air Cooler

Universal Hydraulik LKI oil-air 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 slow-running 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.
