Many years of experience in rating heatexchangers, pumps and heaters is our basis to design your costum aggregate.

Stationary installations in the oil and gas Industrie or mobile aggregate für changing requirements such as in test stands in research and development departments cover a wide range of application fields.

In order to design and manufacture fluid cooled electric motors and generators, it is necessary to provide tempered coolant from a conditioning aggregates.

It cools and heats the media to provide realistic conditions for simulation purpose. Temperature and flow controller maintain the compliance of the nominal values. No matter if the device has a heat in- or output.

To avoid boiling, the water glycol mixture is set under pressure by a pneumatic device. This way it is possible to run the system with temperatures until 110°C.

The aggregate can be operated with the panel onboard or from an extern control center.

Voith Turbo H+L Hydraulic

Voith internal gear pumps are especially well suited for any application in the low, medium, and high-pressure range. The pumps are available as single units, pump combinations (multi-flow pumps, multi-circuit pumps), motor pump units, and servo pumps.

Voith internal gear pumps feature very low pressure pulsation – usually up to 50% less than other comparable internal gear pumps. This considerably improves the controllability of the pump. It also reduces noise emissions by up to 6 dB(A).

Decades of design improvement have resulted in high volumetric efficiency. At rated speed, the volumetric efficiency of our pumps is often 5 to 10% better than other pumps on the market. This makes Voith internal gear pumps the ideal solution for variable speed drives. And that improves your overall efficiency while reducing ma­chine or system power consumption.

Beeing Voith salespartner and certified distributor for more than 40 years, we are looking forward for your enquiry.


In cooperation with HUAWU we can offer high quality brakes. Due to the high vertical range of manufacture a first-class quality and price can be guaranteed.
