  • Touchscreen display, size 12.5 cm (5″)
  • PT1000 temperature sensor, for better accuracy of temperature control
  • Digital temperature setting and display with an accuracy of 0.1 °C
  • Power supply from 100 to 240 V and 50 to 60 Hz
  • Password protected in order to prevent manipulation


Alarm signal:

  • Conspicuous optical alarm
  • Audible alarms with muting and continuous warning indication on the display

  • Parameter changes
  • Functioning of the cooling machine etc.


Graphical display of the temperature profile on the display:

  • Illustration of the actual value and, if requested, the product sensor
  • Viewing period freely selectable


Further features:

  • USB export
  • Network connection
  • Connection for external fault signal, potential-free
  • Maintenance message
  • Test facilities for alarm limits and battery charge level

Laboratory deep freezer with high-quality and precise equipment

Being aware of the high expectations that surround our laboratory equipment, we attach great importance to ensuring that a laboratory deep freezer manufactured by us provides constant temperatures. When opening the door, we minimise the deviations by automatically switching off the circulating air fan. That prevents warm air from being drawn in from the outside. The aim is to keep the stored samples as safe as possible.

In the logical continuation of this idea, every laboratory deep freezer by tritec® is equipped with the touch screen temperature controller TC 2015, with which you can comfortably control the temperature setting, among other things, and display them at any time. In addition, the touchscreen is password-protected to prevent data manipulations by strangers or unauthorized persons. An acoustic and optical alarm indicates both under- and overtemperatures. All events are stored in the event list for approximately four weeks so that they can be checked and exported for analysis via USB or Ethernet. Further technical details and optional equipment of the laboratory deep freezers can be found in the stored data sheets. You also have the possibility to contact us by e-mail or telephone if you have any questions. At tritec®, we meet your expectations of a laboratory deep freezer due to highest standards and state-of-the-art technology.


Customized laboratory deep freezer

We offer you our laboratory deep freezers in several versions, which, depending on the model, cover a temperature range from -5 °C to -40 °C and have a capacity of 140 to 2,300 litres. Both the interior and the exterior housing can optionally be made of stainless steel. If the laboratory deep freezer has to be moved regularly, for example, due to the lack of space, we equip it with castors. Additionally secure the door with a door lock – in the classic version with two keys or electronically. A battery module ensures that the laboratory deep freezer is supplied with power for up to 72 hours in case of a power failure, so that the samples remain undamaged. With the optional GSM module, you will receive an automatically generated SMS or call in the event of an alarm.
