For more than 50 years the employees of Bühler Technologies have been have been developing, manufacturing and distributing components and system solutions in the “Gas Analysis“ and “Fluidcontrol“ divisions.

We offer flexible, system-compatible sensors and devices with state-of-the-art output signals for liquid level, temperature and pressure monitoring as well as for filter and moisture monitoring in hydraulic-systems. With the oil-water and oil-air coolers, filtering units and customer-specific subsystems, we meet today’s requirements in terms of a cost-effective and reliable operation of oil installations, even in hazardous areas. The Bühler Fluidcontrol product line extends the service life of oil and components, provides connectivity for automated operation, facilitates condition monitoring and helps reduce operating and maintenance costs.

Drives and hydraulic aggregates are used in machine construction, raw material production, maritime and many other areas.
In hydraulic systems oil transfers power and motion, in drives it is a vital lubricant. Both as a power transfer medium and lubricant, oil is heated by friction losses during operation.

Since the viscosity of the oil changes along with the temperature, precise temperature stabilisation using oil/air coolers is a vital requirement for systems and drives for consistent power. Furthermore, the temperature also affects ageing behaviour and the service life of oils.

To minimise the negative effect fluctuating oil flow has on the cooler design with varying ambient air temperatures, it is wise to combine the cooler with a built-in circulation pump.
The BNK series is characterised by efficient cooling matrixes, a compact, easy to maintain design and energy-efficient drive motors along with gerotor pumps.
