Wandfluh has launched a new line of energy-efficient powerpacks. The big difference between these energy-efficient powerpacks/basic modules and other commercially available hydraulic powerpacks is the conception of the interface which for the customer-specific circuit set-up can either be arranged directly on the powerpack, or in a decentral location. As a result, from a basic module and a customer-specific design, a system solution especially tailored to the customer's needs is realised.
In order to offer excellent functionality, energy efficiency, small space requirement, durability and reliability at low costs, a customer-specific hydraulic system is often designed using basic modules from the BM standard line.
The core element of the newly developed powerpack/basic modules is an intelligent basic control unit with an integrated economy circuit. The design basically consists of an electric motor, a hydraulic pump, filter units, and a pressure accumulator. For the calculation and the development of the basic control unit and the choice of the electric motor, special attention is paid to energy efficiency.
Up to 80 % energy savings thank to intelligent circuits
Due to the new, intelligent circuit diagram for the basic control unit, the motor operating time can be considerably reduced compared with the conventional accumulator unloading operation. This leads to significant energy savings of up to 80 % during operation. And in addition to the improved circuit diagram of the basic control unit, the new basic modules can optionally be equipped with a process-controlled frequency converter which leads to a further substantial improvement of the energy balance.
CHN Standard powerpack line
The proven CHN standard powerpack line remains part of the programme. It is also available as a ATEX execution. With tank volumes of up to 60 l, a pump flow rate of up to 25.5 l/min, and motor power of up to 7.5 kW, these powerpacks cover a broad spectrum.
