Low temperature -45 °C chest freezers
Maximum temperature stability and temperature consistency
The precise Comfort controller guarantees maximum temperature control and stability. All laboratory
chest freezers with comfort controller are tested to NFX 15-140 thus providing reliable and exact data
on temperature stability and distribution within the freezer.
Access port for an external temperature probe
In the low temperature chest freezers with Comfort electronic controllers there is provision for an
independent temperature probe allowing, for instance, a PT 100 probe or similar measuring elements
to be positioned in the interior. The diameter of the access port is 10 mm.
LED light
The freezer lid has an integrated LED light to improve visibility and potentially reduce lid opening
duration.
One-piece lid
The lid of the LGT models is moulded from a single piece of steel. This makes it extremely resistant to
any deformation from vacuum pressure after lid openings. Because it has no joins but instead radiused
corners and edges it is also hygienic and easy to clean. The strong lid hinges are designed for at least
300 000 openings: they counterbalance the lid from about 45° thus improving safety and reducing the
effort needed to open the freezer.
Optional high-quality baskets
The optional baskets facilitate the storage of small items and can help to improve the handling and
organising of the freezer contents. The baskets have retractable handles can be stacked on the freezer
base and/or hung from the top frame.
NTC product temperature probe
An NTC product temperature probe for logging product temperatures is available as a retrofi t kit for the
low temperature chest freezers with Comfort electronic controllers. The logged product temperatures
can either be read by the electronic controller or transferred to an external documentation system via
the existing RS 485 interface.
Interface converter with documentation software
A special interface converter including documentation software is available for central documentation
of the temperature profi le data and alarm events of multiple appliances via the RS 485 serial interface.
Up to 20 laboratory appliances can be networked for central monitoring and temperature recording.
