The TwinGuard MDF-DU702VX -86°C Ultra Low Temperature Freezer satisfies an industry demand for safe, long-term storage for the most high-valued materials. 2 INDEPENDENT REFRIGERATION SYSTEM , combined with optional liquid nitrogen or liquid CO2 back-up systems, offer a circle of protection unmatched in the marketplace. With two independent refrigeration systems TwinGuard freezers maintain a reliable and uniform -86ºC ultra low temperature environment. Should one cooling system suffer an unexpected failure, the other circuit will keep irreplaceable samples safely around -70ºC until service can be arranged.
Dual Cooling System (TwinGuard ULT Freezer)
In the case of an unexpected failure of one cooling circuit, the other circuit will maintain the freezer in the -70˚C range, protecting samples until service can be arranged.
The dual cooling technology differs significantly from conventional cascade refrigeration technology in fundamental design and operation. In dual cooling systems, two independent refrigeration systems provide a reliable -86ºC ultra-low temperature environment. Should an unexpected failure occur in one cooling circuit, the other can maintain the freezer in the -70ºC range until service can be arranged. This level of ultra-low temperature back-up cannot be achieved by conventional cascade systems.
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. Securely store valuable and irreplaceable samples with the upmost confidence that they won’t be lost in the case of compressor failure.
Efficient Sample Storage
The combination of VIP PLUS vacuum insulation and an enhanced cabinet design with insulated outer door, ensures optimum temperature uniformity, while the reduced wall thickness maximizes storage capacity.
Flexible shelf layout
Multiple shelf configurations allow a variety of storage options. Organize your samples by transferring your current inventory racks.
The EZlatch makes access to stored samples even easier. A colour LCD touch panel allows full user control, even with gloved hands, while the USB port makes transferring logged data to a PC convenient. Significantly extended time to react to any sudden mechanical failures and data logging are ideal for high security applications such as pathogenic research.
