Introducing Telstar's series of low-temperature freezers for safe and long-term storage of samples at -86 oC. These refrigeration units are unique in their class. All features and user benefits are outlined below.


Capacity and flexibility

Compared to traditional freezers, Telstar uses modern ultra-thin vacuum insulation panels (VIP). The use of vacuum insulation allows for up to 30% more usable space and storage of more vials per meter of surface area for the same unit volume. With only 80 mm of insulation, VIP technology enables the best insulation performance. Telstar freezers feature maximum capacity with minimal external dimensions. The unit has 5 interior doors as standard, and the interior is entirely made of stainless steel (shelves, compartment, doors). Optionally, it can have 2,3 or 6 inner doors.

Cooling class with the highest efficiency
VIP technology and an insulated inner door minimize heat flow when the door is opened and allow the temperature to stabilize quickly. The chamber seal is heated by two independent heaters to prevent the seal from being glazed. The pressure equalization port is located in the door and ensures easy opening.

Reliable alarm systems and easy-to-use display
All low-temperature freezers have a bright digital LCD display with easy access menus and a reliable alarm system. Located at eye level, the control system also offers its own diagnostic system with error and disturbance analysis. Telstar freezers have 2 operating modes: economy mode reduces energy consumption by about 15% and extends compressor wear time, or optimal mode for the best temperature distribution. The display, as a standard, stores the history of achieved temperatures during the day and allows to graphically present the stored data as a chart (day, month, year).

Ergonomic design
With a depth of less than 822 mm and 4 large casters, the Telstar freezer can easily change door opening sides - to the right or to the left. This allows you to choose whether you want the door to open on the right or left side depending on your final location in the laboratory.

Easy to service
The main control board is located at eye level, away from dust and moisture. The location of the capacitor filters allows for easy and quick inspection of their condition. All electronics are housed in a safe and compact "black box" protected from dust and moisture.

Two spare batteries, remote alarm (NO/NC/COM), RS485 port and CO2/LN2 connection are included.
