Product Description

Sub-ZeroTM is an emergency lighting battery solution for low-temperature applications. The system comprises a mains-powered control unit that operates alongside the normal emergency control gear to provide low-temperature support when needed. It is for batteries of many traditional formats, so making them suitable for retrofitting or upgrading existing luminaires. The system is the UK designed and built and comprises a compact microprocessor-based controller, which constantly monitors the temperature within a specially configured battery pack and maintains the battery’s temperature within safe levels. If however, the battery’s temperature rises above 25°C then no heating is applied and the system is on standby.
