In the case of unexpected failure of one of the cooling circuits, the other circuit will maintain the freezer continuously in the -70°C range. Medical Device Directive PHCbi has become one of the first companies in our industry to introduce Medical Device certification to underline our strong commitment to product design, quality and safety. In 2010, PHCbi was awarded certification by TUV-Sud to manufacture blood bank refrigerators, freezers and incubators as Class IIa Medical Devices according to the directives 93/42/EEC and 2007/47/EC. At the same time our quality systems were updated to the...

TwinGuard ULT Freezers ULTIMATE SAMPLE PROTECTION The Dual Cooling System offers the highest level of protection through the use of two independent refrigeration systems. If one system unexpectedly fails the other can maintain the freezer in the -70°C range. ENHANCED USE & INTELLIGENT SECURITY The freezers are managed and monitored by an integrated microprocessor controller with a comprehensive alarm system and diagnostic functions. Status and control of parameters are accessible via an LCD information centre. The EZlatch, on the upright models, makes access to stored samples even easier. A colour...

SAMPLE PROTECTION & OPTIMUM CAPACITY Models: MDF-DU302VX-PE | MDF-DU502VX-PE | MDF-DU702VX-PE | MDF-DC500VX-PE | MDF-DC700VX-PE DUAL COOLING SYSTEM Within TwinGuard’s independent Dual Cooling System, efficient ultra-low cooling is achieved through two independent evaporator circuits surrounding the interior chamber. Two independent evaporator circuits -86ºC VIP PLUS vacuum insulation provides up to 30% more storage capacity than a conventionally insulated freezer, without increasing the footprint. A glass fibre core provides advanced thermal properties. Innovative design PHCbi was the first company...

SAMPLE PROTECTION Models: MDF-DU302VX-PE | MDF-DU502VX-PE | MDF-DU702VX-PE | MDF-DC500VX-PE | MDF-DC700VX-PE • Each refrigeration circuit includes a closed-loop cold-wall evaporator configured in parallel to the other. Two independent refrigeration systems • If a component, such as a compressor, fails in a conventional ULT freezer with single or cascade refrigeration circuits with mutually dependent high and low stage systems, the whole system will fail and the freezer will eventually rise to room temperature, putting samples at serious risk of degradation. • Independent compressors, evaporators...

INDUSTRY FIRST INTELLIGENT ECO MODE OPERATION The TwinGuard ULT Freezers can be set to Normal or ECO mode operation, depending on the requirements of the user. Although both refrigeration systems are completely independent, ECO mode establishes an overlapping cycle to significantly reduce energy consumption while maintaining optimum interior uniformity for protection of high value materials. Normal mode maintains the most repeatable, cycling wave form for the strictest of GMP applications.

CABINET CONSTRUCTION Models: MDF-DU302VX-PE | MDF-DU502VX-PE | MDF-DU702VX-PE An automatic vacuum release port allows smooth door opening when a vacuum has been formed due to the large different in ambient and chamber temperature during previous door opening. A manual vacuum release port allows smooth door opening in case of unexpected failure of the automatic vacuum release port. The EZlatch door handle makes access to stored samples even easier. Multiple access ports permit insertion of independent probes, instrumentation or liquid CO2 back-up injectors. Gasketed inner doors seal inside to...

Touch Panel Legend MDF-DC500VX-PE, MDF-DC700VX-PE MICROPROCESSOR CONTROL WITH TOUCH SCREEN DISPLAY The TwinGuard ULT Freezers are managed by an integrated microprocessor controller with LCD touchscreen to simplify all freezer functions. Uniform ultra-low temperature is achieved through a combination of performance systems supervised by the controller complete with alarm, programming and diagnostic protocols. The built in USB port allows logged data to be easily transferred to a PC. 1. Present temperature display field: The current chamber temperature is displayed. 2. Set temperature value display...
