Retrofit of a ETT machine at Fnac in Wijnegem - Antwerp (BELGIUM)
Group VHC entrusted ETT with the task of carrying out a complete retrofit of an old ETT water/air heat pump installed in 1996 at Fnac in Wijnegem.
The modifications, completed in December 2023, involved modernising the machine in several respects:
🔹 The old thermodynamic circuits using R22 were completely replaced by R513A circuits (compressors, expansion valves, piping...).
🔹 The electrical board has been completely updated to comply with the latest safety standards.
🔹 A new control system has been programmed to optimise the energy consumption of the machine's various operating modes.
As well as complying with regulatory changes relating to refrigerants, this retrofit will enable the owner of the installation to make substantial savings on his energy bill.
ETT expresses its gratitude to Group VHC for the trust placed in it!
