As part of their equipment renovation, the aim was to deal with a sensitive room for weighing raw materials.
The aim was to maintain the temperature at between 17 and 19°C all year round with very high efficiency particle filtration.

The issue
Make the existing air conditioning system energy efficient.
Our intervention
ETT designed 2 bespoke machines to meet the site’s many constraints. The idea was also to integrate functions that would make the system energy efficient:
0-10V signal for adapting supply air flow rates to process extractors
Hydraulic coils for extract air recovery
Hybrid tandem compressors for thermodynamic power adjustment
E10 final filtration
Securing with electric heaters on TRIAC
Creation of a specific regulation to adapt to ducts “Mix Ind” supplied by “SINTRA”
Maintenance of uncontrolled overpressure through fresh air management
