The Profi electronic controller.
The menu-guided, multilingual Profi electronic controller with
integrated real-time clock allows the temperature to be set
to 1/10 °C accuracy. The membrane keyboard is dirt resistant
and easy to clean – to meet the most stringent hygiene
requirements in the laboratory.
Integrated alarm systems.
A visual and audible door alarm alerts the user to temperature
deviations. An alarm is also raised if the door is open for longer
than one minute or in the event of power failure.
Integrated data memory.
The Profi electronic controller is equipped with data memory
which records the last 30 alarm events together with the date,
time and maximum temperature. In addition, the internal
temperature is logged in 4-minute intervals. The last
2,800 temperature logs are respectively available, which
corresponds approximately to a 1-week logging period.
Maximum temperature consistency.
Maximum temperature stability in the interior is ensured by the
dynamic cooling system with double ventilation. Very short
defrost cycles allow the internal temperature to be kept almost
constant during the defrost phases. All laboratory appliances
are designed according to the ISO 60068-3 standard with
regard to maximum temperature stability and consistency.
Quality right down to the smallest detail
The MediLine range appliances with a Profi electronic controller are equipped with many features to guarantee the safety of
stored products and temperature stability in the interior. High-quality materials and precise workmanship, extremely efficient

External temperature and alarm documentation.
The laboratory appliances with a Profi electronic controller are
equipped with a volt-free contact for alarm forwarding to an
external remote warning system. The data can be read out of
the internal memory and transferred to a PC via an infrared
interface. In addition the appliances have an RS 485 interface
which enables as many as 20 appliances to be networked with
a central monitoring and alarm system.

Precision with 3-point calibration.
The laboratory appliances with a Profi electronic controller
have a 3-point calibration function
for extremely accurate
temperature control. This permits compensation between the
set
temperature and the actual internal temperature at as many
as three temperature points. Positive or negative changes to
the correction value can be made in steps of 0.1 K.
Mains-independent power supply of the electronic controller.
In case of power failure, the electronic controller is powered
by a battery. As a result, the memory continues to log the
internal temperatures without interruption for another 72 hours.
If external alarm and monitoring systems have been
connected, then data transfer to these is also maintained.
External temperature sensor.
The laboratory appliances have an access port (diameter
7.0 mm) in the appliance ceiling which allows a temperature
sensor to be positioned in the interior.
Energy-e cient hot-gas defrost system.
Defrost less often and faster: the controller calculates the
optimum
defrost cycles based on the compressor run-time.
Then the refrigerators defrost in just 8 minutes and the
freezers in just 12 minutes. The internal temperature is
slightly lowered shortly before so it remains almost constant
during the defrost cycle.
Versatile interior.
Sturdy and versatile: the U-shaped trayslides are height-
adjustable – so refrigerated or frozen products of any kind can
be stored optimally on the plastic-coated grid shelves.
Hygienic benefi t: the interior made of high-quality 304-grade
stainless steel is easy to clean thanks to the large corner radii.
refrigeration components as well as documentation and alarm functions ensure optimum storage of sensitive samples, chemicals
and research materials.
