Maximum protection
Both the internal stainless steel chamber (AISI 304) and the extensive external epoxy powder coating guarantee maximum corrosion protection and a long service life for the ultra-freezers.
Optimized interior design
All ULT freezers are equipped with a height-adjustable shelving system that allows maximum use of the interior space by enabling appropriate placement of storage shelves and cryogenic containers.
Uniform cooling - reduced ice formation
Internal doors with variable configurations (between 3 and 5) and new concepts for the pressure equalization valve reduce ice formation to a minimum. The door's insulation efficiency is also ensured by a system of flat hinges, which improve the functionality of the seals.
Maximale Konnektivität
All ULT freezers are electronically controlled by the latest generation controller that optimizes performance and functionality and enables easy remote setting and monitoring of the freezer.
Environmentally friendly operation
“Environmentally friendly” is our goal; for this reason all of our products use HCFC-free refrigerants.

The washable and reusable air filter is easily accessible at the lower front of the ULT freezer. Rounded corners in the internal chamber allow easy cleaning.
Quiet operation
Both the cabinet and cooling system are designed to minimize noise. When installing the ULT freezers in laboratories or hospitals, the equipment therefore do not disturb the staff working there.
Increased access security
Sample security is increased by BIOGUARD , an optional system that guarantees complete access control. With this accessory, the door is locked electrically, so that it may only be opened using authorized cards with total access traceability.
Exceptional Performance at Sample Storage Temperatures from -40 °C to -86 °C
Sie kombinieren mit dem ACP7-Controller der neuesten Generation Performance und Sicherheit:
- 3 independent microprocessors for adjustment, alarming and connectivity
- User friendly interface
- Touch screen with intuitive operation
- Low energy consumption & continuous monitoring
- Maximum connectivity via 3G communication modules, Ethernet or WiFi
More safety for your samples
Constant wear monitoring of key components: As soon as the preset maximum wear threshold has been reached, an alarm will prompt the replacement of the component, reducing the risk of machine downtime.
The internal temperature is constantly monitored with an alert when it reaches the safety threshold. The device features a backup battery, with regular tests, charging status and replacement alarm. In case of a power failure, the battery offers 30 hours autonomous operating time.
In case of power- or mechanical failure, the BACKUP C02 or LN2 system (optional) guarantees the safety of the samples for approximately 24 hours. In case of prolonged door opening, the CO2 or LN2 back up system starts working to support the immediate recovery of the temperature, thanks to the intelligent monitoring of the electronic system.

NEXUS Green Series
Reduced environmental impact by reducing consumption and resources: In this respect, the Nexus Green product line represents a natural evolution in the field of very low temperatures, combining technological development and environmental sustainability.
Use of natural refrigerants
The use of natural refrigerants (HC) with very low GWP (Global Warming Potential) is the outstanding feature of this product line.
Use of inverter compressors
- Energy savings (up to 30%) compared to fixed speed systems.
- Faster achievement of the set temperature
- Speed adjustment according to demand
- Extremely quiet operation
- Constant temperature by matching compressor output to chamber volume being cooled
- Superior operating performance due to lower temperature fluctuations compared to a fixed speed system

Read more about the Inverter-Technology
Inverter technology is extremely energy-efficient compared to traditional fixed speed systems. This is because the inverter can control and adapt the operating speed in relation to the required temperature. To avoid continuous starting and stopping, the inverter technology keeps the compressor running constantly and modulates its output
according to the programmed temperature.
An inverter unit increases its revolutions to obtain the chosen temperature and reduces its revolutions once the temperature is reached, to then keep it constant with a minimum expenditure of energy.
Unlike a fixed speed system, which starts and stops repeatedly, the Inverter system dynamically varies the revolutions of the compressor to obtain the desired temperature,
significantly reducing energy consumption.
