The Spark Free Freezer line is designed for applications where ignition risk must be minimized during low-temperature storage. The official page states that it can be used for safe storage of potentially flammable items and other temperature-sensitive samples.

The system uses a microprocessor electronic thermostat with LCD temperature display and 0.1°C resolution, allowing temperature adjustment between -10°C and -30°C. It also includes high and low temperature alarms, sensor error alarm, and power failure alarm, with audible and visual warnings.

Public material for the spark-free family also indicates an explosion-proof interior, hydrocarbon refrigeration technology for higher energy efficiency, and CE and ATEX certification across family models. The display and alarm system are battery-backed for 24 hours in the event of power failure.
