Robust and spark-free
This laboratory freezer with static cooling and spark-free interior is designed especially for storing explosive and highly flammable substances. The interior meets all the safety requirements of the EU Directive 94/9EC (ATEX 95). The cooling temperature is continuously adjustable from -9°C to -26°C with the aid of the thermostat integrated into the control panel.
The precision Comfort electronic controller with digital temperature display enables temperatures to be set to 0.1°C accuracy. Symbols indicate the operating status of the appliance at all times. To satisfy laboratory hygiene requirements, the Comfort electronic controller is flush-mounted and has an easy clean membrane keypad.
Integrated alarm systems
A visual and audible temperature alarm alerts the user if temperature deviation limits are exceeded. The parameters for the temperature alarm can be individually set. Visual and audible door alarms are raised if the door is open for longer than 1 minute. Furthermore, the laboratory appliances with Comfort electronic controllers have a visual power failure alarm when mains power returns and a sensor defect alarm.
Integrated data memory
The Comfort electronic controller has an integrated data memory. It logs the maximum and minimum internal temperatures that occurred once the set temperature was reached, the last three temperature alarms and power failures, together with the time, date and duration of the alarm. The respective data can be recalled using the AlarmLog function and read on the display panel.
The laboratory appliances with Comfort electronic controllers provide 1-point calibration for accurate temperature control. This permits compensation between the set temperature and the actual internal temperature. Positive or negative changes to the correction value can be made in steps of 0.1K.
Maximum temperature stability and temperature consistency
In conjunction with the precision Comfort electronic controller, the static cooling system of this laboratory freezer with spark-free interior ensures maximum temperature stability and high-temperature consistency. All the laboratory appliances with Comfort electronic controllers are tested according to the NF X 15-140 standard with regards to maximum temperature stability and optimal temperature consistency.
