Control operating costs related to compressed air systems in the company
Compressed air is an energy carrier that is frequently used in many sectors, particularly when operating production machines and specific pneumatic tools. Despite its abundant use, it is a difficult vector to control, with high operating costs. In an unmonitored installation, production (heat) and distribution (leakage) losses can be as high as 90%. The aim of this measurement is to demonstrate the various levers for optimising a compressed air system.
Organise periodic inspections (to be carried out by an approved body).
Use the conclusions of inspection reports to optimise the installation.
Setting the correct compressed air pressure level
Each compressed air consumer and compressor is designed to operate at a specific pressure. It’s a question of finding the right balance between production, the network (with its load losses) and the various consumers.
Implementation of best practices for compressed air system use
Raising awareness among employees who use compressed air
Adapt operating times to work schedules, e.g. overnight or weekend shutdowns, temporary shutdowns, etc.
Waste heat recovery:
Renewing the system is an ideal opportunity to check whether waste heat can be used. The heat recovered can be used to heat domestic hot water or premises. The use of waste heat with a heat exchanger is generally economical if the compressor size is 15 kW or larger. If conditions are ideal, heat recovery can also make sense with smaller compressors.
The following points should be clarified:
Can waste heat be used for warm-air heating in winter?
Is it possible to install a heat exchanger (used to support heating, domestic hot water production or process heat)?
Does it make economic sense to use waste heat?
How can I remove waste heat from the compressor when it’s not in use (in summer)?
Good to know
Small investments can save even more energy:
Add an automatic trigger system
Installing pressure-reducing valves
Replace timed condensate traps
Equip permanent consumers with solenoid valves
Replace old fittings with low-loss materials
Notice: incentive effect needs to be respected for all requests for subsidies (state or otherwise)
In order to respect the “incentive effect”, no binding commitment (signing a quotation; paying a deposit) can be made BEFORE having received the agreement in principle from the State or the electricity and natural gas supplier following a request for assistance.
SME Packages – Sustainability
5,000€ lump-sum grant for small and medium-sized companies for projects to reduce their environmental impact, costing between €6,650 and €25,000 excluding VAT.
Assistance from electricity and natural gas suppliers for compressed air systems
Since 2015, natural gas and electricity suppliers have been obliged to deliver energy savings to consumers as part of the obligation mechanism. Since then, energy suppliers have been offering support and advisory services, as well as assistance programs for consumers to implement energy efficiency measures.
The following suppliers offer this service to businesses:
