ARC—SARC
Sealed Type Isobaric Acceleration Calorimeter
Product Description
The SARC targets battery energy storage systems (BESS) and high-capacity automotive applications. Its sealed pressure vessel captures both thermal heat release and gas generation in parallel — heat, gas, and reaction kinetics integrated into one experiment, reconstructing the complete thermal runaway profile.
The main characteristics of SARC
· It is equipped with 8 heaters and has three independent temperature control zones.
· It shortens the intervals between each heating step, significantly improving the testing speed.
· The maximum tracking rate of 15°C/min and the resolution of 0.001°C enable more precise capture of the battery thermal runaway process.
Thickened stainless steel explosion-proof cavity + independent explosion-proof box, with multiple interlocking protections against overpressure and overtemperature.
Integrated gas storage and multi-channel sampling system
· The dedicated gas storage chamber captures the complete reaction atmosphere.
· The multi-channel sampling interface is compatible with various analytical instruments such as GC-MS, FTIR, and Raman.
· Time-resolved gas sampling enables the dynamic reconstruction of gas evolution.
Lightweight door opening and closing design that significantly reduces the operator’s workload.

The equipment adopts a dual-chamber sealed constant-volume structure (inner chamber V₁ sample chamber + outer chamber V₂ pressure balance chamber), and is equipped with a multi-zone independent temperature-controlled heating system. Relying on the classic adiabatic algorithm "Heating - Waiting - Searching (HWS)", it can real-time track the temperature rise of the sample, compensate for the heat loss of the chamber, and maintain an approximately zero heat exchange adiabatic environment.
