Description

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

the temperature within a specially configured battery pack and maintains

the battery’s temperature within safe levels. If however the battery’s

the temperature rises above 25°C then no heating is applied and the

the system is on standby.
