Ultra deep freezer
TC series

ColdFAST TC series - the new generation of ultra-low temperature freezers

Maximum safety. Energy efficiency. Technological precision.

The ColdFAST TC series represents the latest generation of high-performance ultra-low temperature freezers for professional use in laboratories, biobanks, pharmaceutical facilities and research institutes. With state-of-the-art technology, innovative double cooling and exceptional reliability, these appliances are the first choice for long-term storage of temperature-sensitive samples at up to -86 °C.

Your product benefits at a glance

  • Two inverter compressors for maximum operational reliability
  • Energy-efficient, quiet and sustainable operation
  • Large 10" touch display - intuitive & fully networked
  • Seamless temperature monitoring and recording
  • Stable storage temperature down to -86 °C
  • Versatile expansion options for GMP & FDA-compliant applications
  • Robust, durable construction - ideal for continuous operation
  • S-TwinDrive™ system - two compressors for double safety

    At the heart of every appliance in the TC series is the intelligent S-TwinDrive cooling system with two independent inverter compressors. This system not only ensures constant and even temperature distribution, but also guarantees operational reliability in the event of a fault:

    • Should one compressor fail, the second keeps the temperature stable at up to -75 °C.
    • Ideal for critical long-term storage where sample integrity must be guaranteed without compromise.
  • Highest precision & energy efficiency
    • Temperature range from -40 °C to -86 °C, adjustable with an accuracy of 1 °C
    • Inverter technology adjusts the compressor output to the cooling requirement in real time → up to 9.9 kWh daily consumption
    • Housing with vacuum panel insulation (130 mm) for outstanding energy efficiency
    • Direct cooling system with sound-insulating design - noise level max. 54.4 dB(A)
  • Two model sizes - for every storage capacity
    • 530 litres (model U530 TC)
    • 780 litres (model U780 TC)
      Each size offers plenty of space for a large number of samples, while at the same time optimising the footprint and ergonomics.
  • Sophisticated design for everyday use
    • Ergonomic handle, pressure equalisation valve and smooth guide rails for effortless door opening
    • 4 universal heavy-duty castors and 2 levelling feet for safe installation and mobility

    • Simultaneous display of ambient temperature and input voltage for environmental monitoring
    • Connection to building management system (BMS) possible via remote alarm interface
    • UL and CE-certified
  • Equipment & comfort functions
    • PT1000 temperature sensor in stainless steel protective housing
    • Pre-filter - easily accessible & replaceable
    • Vacuum relief valve for immediate pressure adjustment when opening
    • Solid stainless steel hinges and reinforced shelves for high load capacity
    • USB interface, mains voltage stabiliser, temperature recorder (ink-less) - optionally expandable
  • Optional accessories
    • CO₂ backup system incl. controller and valve
    • Racks and cryoboxes for systematic sample organisation
    • Temperature recording via Modbus (21 CFR Part 11-compliant)
