2. Unit description
The ULTRA.Guard™ ultra-low temperature freezers UF V were produced with great care using the latest
tools for development and production. They were optimized for safe long-term storage of samples in the
ultra-low temperature range and reach the minimum temperature of -86 °C / -122.8 °F in approx. 9 hours.
You can operate the freezer in a temperature range from -86 °C / -122.8 °F up to -40 °C / -40 °F.
The UF V units are regularly equipped with the progressive RFID system (optional for UF V UL), offering
personalized access control. The UF V UL units are regularly equipped with the advanced voltage boost-
er AVC (option for UF V) and a data logger (option for UF V).
The freezers are available with the door hinged on right or left and for several different voltages.
Easy opening and closing door mechanism and access control
A pushbutton permits opening the automatic door mechanism without using your hands. A pull-tight func-
tion automatically closes the outer door when slightly open. For personalized access control, the freezer
door is RFID controlled (standard with UF V, option for UF V UL) and an optional door locking with key is
available (option for UF V UL).
The freezer is regularly equipped with a key switch (main power switch) to switch on and off the unit.
Controller
For temperature control, the freezer is equipped with the microprocessor controller RP1 with a digital
display. The controller keypad can be locked (keyboard locking). Temperature setting is accurate to one
degree. The controller is mounted at eye level.
The controller offers an error diagnostics system generating audible and visual warning and alarm mes-
sages. During power failure, alarm function and control remain active during 72h. The controller provides
password protection for the setting menus. Testing the alarm functions is always possible.
The controller monitors ambient temperature and issues an alarm if it exceeds an adjustable value.
A counter of operating hours / weeks is included.
Housing
The inner chamber and the inside of the insulated outer door are made of stainless steel (material no.
1.4301 (V2A) in Germany). The housing is RAL 7035 powder-coated. All corners and edges are also
completely coated. The inner surfaces are smooth and therefore easy to clean. Easy front access permits
filter cleaning without tools. A 10 mm access port prepared to be finalized by the user and an additional
optional access port serves to introduce a cable and sensor of a measuring device.
The buildup of ice in the door area is minimal due to perfect closing of the inner and outer doors and a
heating of the outer door gasket. Precise spatial distribution of the cold in the interior ensures storage of
all samples at an identical storage temperature. The prevention of thermal bridges protects against de-
frosting. The combination of vacuum insulation panels (V technology) and CFC-free polyurethane foam-
ing maximizes the cold storage capacity.
The freezer has four compartment doors. You can insert stainless steel shelves are make optimum use of
the interior. You can flexibly arrange the shelves to use the interior in a variable and optimum manner.
Inventory racks (stainless steel storage racks with cryo boxes, chap. 13) are optionally available.
Vertically adjustable castors with locks serve to move the freezer and then place it safely at its destina-
tion.
