-86°C/-80°C Ultra-low temperature freezers for the ultimate sample protection.
Twice the protection. Double your peace of mind.
The TwinGuard series upright and chest -86°C/-80°C ultra-low temperature freezers from PHC has the industry's most time-tested redundant cooling systems designed to protect the viability of your biological samples. Ideal for critical preservation applications, TwinGuard's patented cooling engines deliver reliable performance working together, both independently and concurrently, to provide continuity in stored product protection over a range of real world conditions.
The advanced combination of redundant cooling systems, intuitive electronic controls, on-board monitors and frost-mitigating, ergonomic cabinet design represents more than 50 years in refrigerated sample protection for the life science industry.
TwinGuard Dual Cool Lab Freezer Performance
Superior and reliable preservation of your biological samples cannot be compromised for any reason. The primary purpose of a -86°C/-80° ultra-low temperature freezer is to protect a stored biological by achieving and maintaining uniform temperature to assure cell viability, regardless of where samples are stored inside. PHCbi TwinGuard Series -86°C/-80°C ultra-low temperature freezers undergo thorough temperature uniformity testing allowing us to provide our customers with temperature uniformity data that upholds our excellent performance.
Temperature Uniformity Data
Data featured is for the TwinGuard Series Upright Freezer model MDF-DU702VXC-PA.
TwinGuard Series -86°C/-80°C chest and upright freezers demonstrate temperature stability in the steady state, quick pull-down on initial startup, fast recovery following a routine door opening, and slow warm-up during a power outage.
TwinGuard Ultra-low Temperature Freezer Reliability
While performance is the first test of our product, long-term reliability is essential for protection of your research, peace of mind and return on your investment. The patented TwinGuard dual cool lab freezer system enhances the PHC reputation for reliability in refrigeration safety and predictive maintenance which is second to none in the world.
TwinGuard's dual cooling system offers the highest level of sample protection through the use of two independent refrigeration systems that maintain -86°C temperature. The two circuits work together for fast temperature recovery, while the secondary system keeps the temperature at -70°C if a service event occurs. With two independent systems each sustaining ultra-low temperatures, your samples remain safe. Optional CO2 backup provides an extra layer of protection.
Integrated Access and Frost Mitigation Design
Opening the door of any ultra-low temperature freezer is not an insignificant event. Because extreme inside/outside temperature differentials often exceed 116°C (212°F), careful planning is encouraged before accessing the interior. To minimize duration of the door or lid opening, users should know the location of stored product inside the freezer before accessing. Such best practices lead to better chamber uniformity, faster recovery of setpoint temperature and longer freezer life.
The new EZlatch is the centerpiece of a holistic inventory access and frost mitigation system. The simplified one-handed, comfortable operation keeps TwinGuard upright freezers operating at maximum energy efficiency.
EZlatch design is available on TwinGuard series freezer models MDF-DU702VXC-PA, MDF-DU502VXC-PA and MDF-DU302VX-PA.
New design features color touchscreen LCD interface.
TwinGuard Upright Controller Platform
TwinGuard Series freezers are managed by a microprocessor-based digital controller designed for setpoint security, temperature display, system status, alarm functions and predictive performance advisories.
Data is continuously collected throughout the system to predict any deviations from expected performance, which would in turn initiate alarms with audible and visual alerts. All performance attributes are displayed and an internal time/temperature log is expressed in graphic form.
An eye level, door mounted color LCD touchscreen allows full user control while the USB port makes transferring logged data to a PC convenient. The new TwinGuard LCD interface is available on TwinGuard series freezer models MDF-DU702VXC-PA, MDF-DU502VXC-PA and MDF-DU302VX-PA.
TwinGuard Freezer Sensible Energy Management
As refrigeration technology evolves in response to a global demand for non-ozone depleting refrigerants and more efficient operating costs, TwinGuard -86°C freezers confirm the PHC investment in a new generation of ultra-low temperature cooling systems.
While reducing power consumption remains a priority in our research and development efforts, the scientific community can be assured that PHC will never pursue an engineering policy that places operating costs above performance and reliability that are so critical to global research.
Patented VIP® (Vacuum Insulation Panels) Plus
PHC was the first company to use VIP Plus cabinet insulation, standard on TwinGuard cabinets. VIP Plus is a composite formed of thin-profile vacuum insulation panel substrates supported by foamed-in-place urethane insulation within the exterior walls. VIP Plus cabinets offer additional interior storage volume and exceptional insulation value within a compact footprint.
Choosing Your TwinGuard Series -86°C/-80°C Upright or Chest Freezer
PHC offers TwinGuard ultra-low temperature freezers in four sizes: 12.7 cu.ft., 18.6 cu.ft., 25.7 cu.ft. upright freezers and a 25.3 cu.ft. chest freezer.
LabAlert Monitoring System - PHC offers a real-time monitoring and notification system developed to protect your stored product investment. PHC's LabAlert provides independent wireless monitoring for refrigerators and freezers. The secure, cloud-based solution offers comprehensive monitoring with customizable dashboards for easy user interface. No software installation is required. Supports FDA 21 CFR Part 11 compliance. LabAlert is scalable to meet corporate enterprise standards. It works across multiple units, multiple locations and easily adapts to growing facilities.
