  • Possibility of assistance
  • Subsidies available

To make this measure more effective and tailored to the specific context of your company, we recommend that you first perform an overall analysis of your energy situation.

Installation or replacement of a centralised refrigerating system

Cold production is used to cool down a room or a component, preserve food products, control the temperature of a process or ensure proper air conditioning.

Installing a centralised refrigeration unit generally offers better efficiency than a decentralised installation, reduces noise and heat disturbance in occupied rooms and frees up space in the cooled area, as the equipment is installed in a dedicated room.

However, this solution requires a higher investment and the involvement of a qualified refrigeration technician. Below are all the necessary steps to prepare for the installation of a centralised refrigeration system.

Definition of cold production requirement

Analysis of the current situation

  • Determine the condition of the existing installation (if one is already in place), for example: age, load level, general condition, temperature level, energy consumption and associated costs, etc.
  • Assess the energy consumption of the production unit(s) as well as the peripheral components of the installation.
  • Monitor performance indicators and identify any malfunctions. (e.g. pressure and temperature curves)

Assessment of the building’s cooling requirements by a qualified craftsman or an engineering office

  • Analyse the company’s current energy situation
  • To go further:
    • Analyse and reassess the technical characteristics of the installation, such as temperature level and nominal output
  • Check the technical limitations of the existing unit(s)
  • Check whether it is possible to optimise the existing installation. See measure Optimising the cold production system
  • Identify a location for installing a new centralised cooling unit

Identification of a centralised cold production solution suited to the company’s needs

Elements of the solution

Define the scope of the requirements, for example:

  • Replacement of the main production unit
  • Modernisation of the cooling towers
  • Replacement of the entire cooling installation
  • Adaptation of the distribution network
  • Insulation
  • Control system
  • Integration of an adiabatic cooling system
  • etc.

Using waste heat

In principle, cooling is generated by electric compressors. This process releases a high percentage of the energy in the form of waste heat. This heat can be repurposed for other energy needs, such as domestic hot water production, heating of production halls, material drying, etc.

Feasibility check of the project

  • Based on the requirements analysis, define the scope and the solution, in collaboration with an engineering office or a qualified craftsman
  • Draft the specifications and requests for tenders
  • Applying for operating permits In case of modifications to existing installations, and especially when installing new equipment, verify the validity of existing operating permits.

State subsidy application

State subsidies

To respect the ‘incentive effect’, no binding commitment (such as signing a quote or paying a deposit) may be made BEFORE submitting the subsidy application or receiving the agreement in principle from the State or the electricity and natural gas supplier following an application for aid.

SME Packages – Sustainability

  • Aid for small and medium-sized companies, covering up to 70% of eligible costs for carrying out a project aimed at reducing their environmental impact. The total project cost must be between €3.000 and €25.000 excluding VAT.
  • Points de contact :
  • SME aid scheme – Aid for consultancy services

Aid for small or medium-sized enterprises, up to 50% of the fees of external consultants for consultancy services.

Aid for small and medium-sized enterprises, up to 10% or 20% of the amount of miscellaneous investments aimed at promoting the modernisation and competitiveness of the Luxembourg economy.

N.B. State subsidies cannot be combined for the same project.

Application for subsidies from electricity and natural gas suppliers

Since 2015, natural gas and electricity suppliers have been required to achieve energy savings for consumers under the obligation scheme. Since then, energy suppliers have been offering support and advice, as well as subsidy programmes to help consumers implement energy efficiency measures.

The following suppliers offer this service for companies:

N.B. Supplier subsidies can be combined with any state subsidies for the same project.
