A strong character shows its sensitive side. In all Memmert appliances, heating performance, heating-up
speed, air exchange rate and device specific parameters such as humidity or pressure are syntonised with
the utmost precision and can also be adjusted by the user during operation. Therefore, the appliances’
temperature stability is unparalleled, they save energy and last a scientist‘s half lifetime.
The new models score in all areas:
• Higher air flow rate and faster drying processes thanks
to enlarged air intake and exhaust air vents.
• Fan speed and air flap position adjustable via
the ControlCOCKPIT.
• Different loading types and volumes influence heat
distribution in the chamber, particularly during
heating-up. Thanks to the HeatBALANCE function,
this can be compensated.
• By activating the SetpointWAIT function, the process
time does not start before the set temperature is
reached at all measuring points – optionally including
freely positionable Pt100 sensors in the interior.
• Optimum distribution of temperature and humidity in
Peltier-cooled appliances thanks to individual controllability
of Peltier elements.
Simple but brilliant – All-round surface heating
Ideally, an equally heated cubic interior radiates heat in the same intensity from all sides. The smaller the heated
surface in a temperature control chamber, the worse the temperature distribution. Punctually radiating ring
heaters with an overall heating element length of one metre will probably even start to glow, making a gentle
and accurate adjustment considerably more difficult to achieve. Heat transfer must be supported by motor-driven
air circulation, dark loads are excessively heated and loads in shaded areas do not heat up properly.
WORTH KNOWING
A Memmert oven with a chamber
volume of 750 litres is surrounded
by more than 52 metres of heating
elements.

Physics cannot be outsmarted, therefore the only
way to achieve optimum temperature homogeneity
and stability is the unique Memmert all-round surface
heating system. Heating circuits surrounding the
interior in ovens, incubators and sterilisers are
individually controlled to exactly provide and hold the
desired temperature at every point inside the chamber.
The heating is not simply switched off when the set
temperature is reached, but sensitively and evenly
controlled according to requirements.

WORTH KNOWING
No other manufacturer has more
experience in Peltier technology and
offers a greater variety of these pre-
cise and energy-efficient temperature
control appliances than Memmert.
The triumph of Peltier technology
At the turn of the millennium, Memmert opened a new chapter
in its history of innovation. The heating and cooling process of
the interior in temperature control appliances is by nature very
energy intensive. Therefore, Memmert was the first manufacturer
that consequently developed energy-efficient and environmentally
friendly laboratory appliances.
Saving resources – a task for the future
At Memmert, every innovation is thoroughly tested with respect to its sustainability. Whether climate chambers
or conventional heating and drying ovens, all appliances feature outstanding energy efficiency, thanks to their
finely tuned control technology in connection with sophisticated individual heating concepts.
The insulation concept has been optimised. Insulation of up to 90 mm and insulation inserts in the door are two
important changes to almost completely prevent thermal bridges and thus heat emission from the chamber.
WORTH KNOWING
All Memmert appliances are made
of stainless steel and thus nearly
100 % recyclable.

Heat emission at 250 °C, air flap closed
In the same way as in a heat pump, in heating
operation, thermal energy is removed from the
ambient air and introduced into the chamber.
Due to the closed Peltier cooling system, no
outside air is exchanged. The advantages:
No dehumidification of the chamber and
heavily reduced risk of contamination.
In contrast to compressor technology, Peltier
technology works in a particularly economical
and energy-saving manner at temperatures close
to the ambient temperature, since energy is only
required if heating or cooling is needed. Heating
and cooling are perfectly fine-tuned.

Better than any standard*: Thanks to the patented MEMMERT air circulation system,
the surfaces and operating elements of the new appliances only heat up moderately,
even at a chamber temperature of 300 °C
