The Benefits of Electric Driven Hydraulic Power Units

Hydraulic power units (HPUs) are crucial components in a multitude of industries, powering a vast range of machinery with precision and efficiency. Among the various types of HPUs, Electric Driven Hydraulic Power Units stand out for their myriad of advantages, particularly in terms of energy efficiency, environmental friendliness, and performance. In this blog post, we'll delve into the core benefits that these electric-driven systems offer and why they could be the ideal choice for your hydraulic needs.

Enhanced Energy Efficiency

One of the primary benefits of electric-driven hydraulic power units is their energy efficiency. Unlike traditional combustion engines, electric motors convert electrical energy into mechanical power much more efficiently. This not only means lower energy consumption but also reduced operational costs, making them a cost-effective solution for businesses looking to maximise their investment. The Daikin EHU 40 series, the SUPERUNIT Hybrid 40 series, and the Nachi NSPi series of Hydraulic power packs are at the forefront of energy saving in the Hydraulics world, with the inverter motor driven EHU 40 series notably offering a 30% reduction in power consumption over it's predecessor as well as a reduction in noise and heat generation.

Environmentally Friendly Operation

Environmental concerns are increasingly directing industrial processes. Electric powered HPUs contribute to a greener footprint, as they do not emit gases or produce pollutants that are commonly associated with combustion engines. This is incredibly beneficial for companies striving to comply with stringent environmental regulations and for those who prioritise sustainable practices within their operations.

At Zeus Hydratech, we are always looking for ways to utilise new energy effecient tecnology and components in our project where possible- for example, in all our Industrial Modular Power Packs, we are utilising the more energy efficient IE3 Electric driven motors as the primary mover. The IE3 motors are described as 'premium efficiency' and are ideal for continuous (or near-continuous) operations and offer substantial energy savings over the IE1 and IE2 versions.

Reduced Noise Levels

Workplace noise can be a significant concern, especially in enclosed spaces or areas where employees are exposed for prolonged periods. Electric-driven HPUs are generally quieter in operation compared to their diesel counterparts, thereby contributing to a more comfortable and compliant working environment.

Superior Precision and Control

When it comes to control and precision, electric-driven hydraulic systems provide superior performance. These units can offer more precise control of pressure and flow, facilitating more exact movements and functionality in machinery. This level of control is paramount in sectors such as aerospace and motorsport, where precision is synonymous with safety and performance.

Low Maintenance Requirements

Maintenance can often be a burdensome and costly aspect of machinery operation. Electric HPUs are renowned for their low maintenance requirements. With fewer moving parts and no need for fuel filters, oil changes, or engine services, these units are a hassle-free alternative, ensuring minimal downtime and consistent performance.

Versatility in Application

Flexibility in operation is another highlight of electric-driven hydraulic power units. They can be designed to operate effectively in an array of environments - from indoor facilities where air quality is a concern, to remote and offshore locations where the supply of fuel may be challenging. This versatility makes electric HPUs an attractive option for a wide range of applications.
