These periodic tests are extremely long (even 24 hours continuous) and occur within low temperature tunnels.
Italian Transport Ministry chose Assing to realize these systems and now Assing Isotherm is the reference system installed in all Italian Ministry Testing Centers.
Assing Isotherm can perform simultaneous tests on multiple vehicles and can generate renewal and homologation certificates for all isothermal vehicles with or without refrigerating / refrigerant systems on board. Isotherm can issue ATP national and international certificate and communicates directly with National Data Processing Center of Ministry of Transport.
Isotherm’s peculiarity is the management not only of the test cycle but also, through a specific PLC control, of thermo-hygrometric conditions of the test tunnel.
The system mainly includes:
- Isotherm control system.
- Temperatures acquisition system: SIT12-PT (4 units) – PT100 probes (48 probes) – telescopic support posts for PT100 probes.
- ISOTHERM 7 software.
- Switching power supply box for refrigeration units.
- Heating units (up to 5 channels).
