Description
The BNK series consist of the following components:
• cooler matrix
• fan case with mounting feet
• fan motor assembly consisting of an AC motor, fan and finger guard
The cooling matrix and fan can be separated from the fan case individually without the need to dismantle other components.
The cooling matrix of the BLK series is made from aluminium. The matrix is suitable for use with hydraulic fluids but is not suitable for water or water based fluids.
The cooling matrix can be equipped with by-pass valves of different configurations (see type code).
Depending on the application or system requirements, off line filtration is often the appropriate solution. We recommend in these cases that you combine this off line circuit with an off line cooler. Suitable units can be found in our BNK series. These units are also suitable for upgrading existing systems.
