Customized Hydraulics


Reducing the complexity of your HVAC project

All over the world, our hydraulic units help customers reduce project time and complexity. With more than 10 million already in action, you can rest assured that they have been field-tested to perfection. The units consist of pump housings with built-in functionalities combined with high quality motors. Your benefits include seamless integration, significantly reduced manufacturing costs, and trouble-free operation.


Tailor-made solutions

The modular approach of our hydraulic units allows for high degree of customisation. Examples of customisation options include air vent, pressure release valve, and temperature sensor, and other functions of the primary circuit of the individual system.


Composite experts

Composite is an extremely flexible material that makes customisation and, thus, system integration easier. We manufacture approximately 5 million highly complex hydraulic units from composite moulding every year, and your project will undoubtedly benefit from this experience and expertise.
