  • Three sizes with 360, 528, 729 l interior volume offer flexible storage capacities
  • Individual optional features
  • Additional insulated inner doors for minimised temperature loss when doors are opened
  • High product safety thanks to two independant refrigeration systems
  • Low energy consumption
  • Ergonomic attractive design for easy access to the products
Further Product InformationUltra-low freezers of the PHCbi TwinGuard-series are characterised by optimum cooling performance and high reliability. The Dual Cooling System provides the highest level of protection through the use of two independent refrigeration systems. If one system unexpectedly fails, the other can maintain the freezer’s temperature uniformly in the -70 °C range.

VIP PLUS vacuum insulation provides up to 30 % more storage capacity than a conventionally insulated freezer without increasing the footprint.

The devices feature a colour LCD touch panel which allows full user control, even with gloved hands. The integrated microprocessor controller includes a non-volatile memory, a potential-free alarm contact and an individually configurable door and temperature alarm. A built-in USB port allows logged data to be easily transferred to a PC.

A unique circulating air control system ensures optimum temperature distribution in the test chamber and precision temperature control.

PHCbi TwinGuard ultra-low freezers satisfy the requirements of the ICH guideline as well as the requirements of GMP.
