Classic 'ARC-type' adiabatic calorimeter (Phi-tec I) and also low-thermal inertia or low phi-factor version (Phi-tec II) to provide thermal stability, runaway potential, vent sizing (according to DIERS methodology) and thermo-kinetic data on liquids and powders. Used both in process industries and for material hazard testing.
The Phi-TEC I is an adiabatic calorimeter that can be used to determine the heat evolved and pressure developed during an uncontrolled exothermic runaway reaction. It is the modern alternative to the classic "ARC" developed by Dow Chemicals and can be used for thermal hazard studies of liquids and powders, at a scale typically from 0.5 to 5g.
A version for testing small batteries and battery components is also provided which can be used to determine maximum safe temperature and by connecting to a cycler, the maximum discharge rate and maximum safe over voltage. For details of this and larger batteries and packs, see the Battery Testing Calorimeters produced by HEL.Read more
The phi-tec II is top of the range adiabatic calorimeter that can generate thermal runaway data which can be used directly to understand consequences on plant scale. This is enabled by the ability to work under low phi-factor (low thermal inertia condtions) and hence also enables Vent-Sizing using DIERS methodology. It can also serve as a conventional "ARC-type" calorometer for general applications and in this mode uses the exact same test cells as ARC-devices.Read more
This calorimeter enables the maximum safe temperature, maximum discharge rate (current) and maximum overchage (voltage), to be determined, above which thermal runaway explosion can occur, in different sizes and shapes of batteries.
Specially designed for safety testing of large and small scale (Li-ion & similar) batteries and components, the BTC is an evolution on standard "ARC-type" (TM) adiabatic calorimeters.Read more
