Implementation of a variable speed system on dust or fumes extractor fans
The project consists in setting up a speed regulation system on the extractor fan, activated by the machines in operation which actually require the extraction of sawdust or fumes. It involves the addition of valves and a speed variator on the extractor fan. The valves open only when the machine is operating and the fan flow rate adjusts according to the pressure.
Installing this technology, which has been available on the market for more than 5 years, the company can save significantly, up to 50%, on its electricity bills (depending on the baseline production regime) and reduce its carbon footprint. This measure is quite simple to implement, can show a rapid return on investment, and does not require a production shutdown during installation.
Use of high-performance, combination tools to reduce cycle time
The measure involves replacing simple machining tools, changing the production mode and avoiding shutdowns for unplanned maintenance and cleaning.
Use of high-performance machining tools to increase machining speeds.
Use of combination machining tools to reduce the operating time of machine tools.
Optimisation of production changes using the SMED method (Single Minute Exchange of Die – rapid tool change in less than 10 minutes).
By installing these technologies, which have been available on the market for over 5 years, companies can save up to 30% on electricity costs and reduce their carbon footprint. This measure is not simple to implement and would entail a medium-to-long term return on investment. This measure can be implemented with only a partial production shutdown during installation.
The use of articulated arms to extract dust and fumes is a system that optimises dust collection.
Dedicated profiled nozzles must be placed as close as possible to the points generating dust or fumes.
It is necessary to set up a heat recovery system on the extracted air flows with air reinjection to balance the pressures.
By installing these technologies, which have been available on the market for over 5 years, companies can save up to 20% on electricity costs and reduce their carbon footprint. This measure is quite simple to implement and would entail a medium-to-long term return on investment. However, this measure requires a production shutdown during installation.
Some older machines do not have standby mode or energy-saving mode. Companies need to purchase new machines equipped with automatic shutdown functions to save money during periods when their equipment is not in use. Here are some examples of equipment requiring ECO mode: lubrication pumps, cooling fans, hydraulic pumps, servo motors and display standby (screens).
Installing this new technology can save businesses up to 5% on electricity consumption and reduce their carbon footprint. This measure is not easy to implement and cannot be justified by the cost of energy alone. This measure requires a temporary shutdown of production during installation.
Company halls and workshops, often characterised by large open spaces and high ceilings, present a particular challenge when it comes to installing an energy-efficient, targeted heating system. The ideal heating system for halls must therefore be able to heat the different work areas individually and produce heat at the right height.
Halls and workshops have specific heating requirements due to their size and use. It is therefore essential to carry out a thorough requirements analysis before installing a new heating system.
Optimising the operating costs associated with the energy efficiency of your company’s building envelope
Much of the heating energy is lost through leaks in the poorly insulated or non-insulated building envelope. Improving the building envelope will therefore lead to considerable savings in heating and/or cooling requirements.
The use of domestic hot water varies from company to company. In some cases, it is used for sanitary installations and cooking, while in others, hot water is used for manufacturing or to assist in the production of materials or services. As a result, it is important to put in place the right solution, tailored to the specific situation.
Below is an approach that shows the stages and benefits of changing your domestic hot water (DHW) production system.
Energy savings: lighting, a key element in energy consumption in the workplace
Lighting accounts for around 10% of electricity consumption in buildings. The potential savings are quite varied and depend heavily on the condition and management of the lighting system. In order to unlock the full potential, this measure proposes a range of optimisation measures, from simple practical initiatives to a complete overhaul of the lighting system.
