Energy Efficiency Audit

A huge amount of energy is wasted due to leaks in compressed air systems. Capacity losses of up to 20% are common in many installations. During an Energy Efficiency Audit Atlas Copco checks the static and dynamic pressure for your air tools on the line. The pressure drop is measured and documented and a visual inspection of the air installation is performed. Based on the information acquired, using the Energy Efficiency Calculator, Atlas Copco recommends the correct installation in terms of air line accessories and various other aspects.

Atlas Copco USA - Eco Design
Eco Design and environmental aspects of product development is nothing new to us. Atlas Copco has a history of developing modular tools with a deep respect for materials and natural resources used in the products. We always strive to maximize the functionality of the product and at the same time minimize the energy consumption to make sure the environmental impact is as low as possible. By developing accurate tools we make sure the customer never has to waste time or energy to re-do an operation. For battery tools we also have the option to connect multiple tools to one controller and thereby decrease the standby energy consumption considerably.

Eco Design is all about minimizing a product's environmental impact during its entire life-cycle, including extraction of raw materials, manufacturing, customer usage and recycling while maximizing the productivity.

Our approach to Eco Design

Eco Design
Within Industrial Technique we approach Eco Design from six different areas. These form the core of the Eco Design review performed in each product development project. This procedure helps define Eco Design targets early in the project.
    We avoid hazardous substances and materials listed on the Atlas Copco Restricted & Prohibited list.
    We use materials and structural features to minimize the product’s weight and invest in strong, durable materials to protect the product.
    We avoid mixing materials since blends inhibit recycling and consider fastening methods to facilitate disassembly.
    We consider how the final product will be used in order to minimize energy and resource consumption in the use phase, in production and during transportation.
    We design with recycling in mind. We promote repair and upgrading, especially for long lasting and system-dependent products. To increase the customer’s awareness regarding the importance of recycling, we are now including Recycling Instructions in the Product Information (PI).
    We prepare for upgrading, maintenance and recycling, through labelling, modularization and information in the product information.
This is how we do Sustainable Productivity in practice!
