For the heavy duty gear units produced by SEW-Eurodrive, Universal Hydraulik has developed special air cooling systems which are ideally suited to the modular concept adopted by the gear unit manufacturer. Thanks to a special feature of their construction, the cooling systems are exceptionally compact and efficient.

Combining the ability to cool and heat in one piece of equipment is a tricky business: How did Universal Hydraulik succeed in integrating the two thermodynamic processes of warming and chilling in a single device?

In order to prevent an oil-water mixing in the cooler, two heat exchangers with separate circuits are often used. However, there is also an easier way.

New heat exchangers from Universal Hydraulik

Particularly when it comes to cleaning the water side, tubular heat exchangers have advantages over plate heat exchangers. Universal Hydraulik has now presented two innovations for this tried-and-tested product. One of these was given a closer look by fl uid at Kaeser Kompressoren in Coburg.

Hybrid coolers ensure efficiency in oil cooling

Fire engines, gearbox manufacturers, wood working, mechanical engineering, in fact anywhere where oils are used, there is cooling. This is why the hybrid cooler from Universal Hydraulik comes in many differed versions.

Primary and secondary circuits provide high cooling output for a press.

Due to the lack of a cooling tower and corresponding available water circuit, a system specialist developed a solution comprising two inter-linked cooling circuits for dissipating the cooling output of a large hydraulic press.

Pipe bundles with vanes increase the heat exchanger surface many times on the oil side

Plate or pipe-bundle heat exchangers - this is a question often decided by designers in favour of the former, due to the compactness that can be achieved. But this supposed advantage no longer comes into the balance, thanks to the development of a pipe-bundle heat exchanger with vanes.
