These spark-free laboratory freezers feature static cooling with an electronic controller system ensuring high temperature consistency and uniform temperature distribution. They are designed especially for storing explosive and highly flammable substances but are also suitable for non spark-free applications for the storage of temperature-sensitive and high value products.
- Electronic control system with 0,1 °C temperature adjustment
- Audible and visual alarms for door open and temperature (user-adjustable)
- RS485 interface volt-free contact
- On-board data logging
- Pre-drilled access port
- Self-closing door with fitted lock
The controller stores minimum and maximum interior temperatures, the last three temperature alarms and power failures, together with the time, date and duration of the alarm. The digital display indicates the exact temperature and the operating status. The refrigerant used is a hydrocarbon.
Temperature range: −9 to −26 °C and −9 to −30 °C.
Certifications: All Liebherr laboratory freezers with spark-free interior are tested according to the ATEX Directive. They have a Zone II nA interior for gases, taking into account the safety requirements of material category 3G. They are, therefore, suited for storing explosive and highly flammable substances.
