TL1 Testing

Specialised type-testing for railway HVAC performance.

TL1 testing verifies that railway HVAC and climate control systems meet thermal comfort requirements under controlled, repeatable conditions. Allovis performs climatic chamber testing and climate comfort testing in line with EN 14750, EN 13129 and EN 14813, covering passenger saloons and driver cabs alike. Full data acquisition — temperature, humidity, airflow and pressure — is combined with HVAC control validation to give manufacturers robust, standard-compliant evidence for type approval and homologation.
