Twinguard® Series -86°C Upright Freezers

PHCbi TwinGuard® Ultra-Low Temperature Freezer Series:

• Upright and chest freezers
• Two independent refrigeration systems offer a circle of protection unmatched in the marketplace.
• Performance down to -86°C is based on integrated complementary refrigeration circuits, robust cabinet design, and intuitive, intelligent controls and monitoring.
• TwinGuard Series long-term storage laboratory freezer is ideal for safe, long-term storage of high-value products, such as stem cells, embryos, cell lines, rare specimens, and other biological materials.

Ultimate Sample Protection

• The dual cooling system offers the highest level of sample protection by using two independent refrigeration systems that maintain normal temperatures as low as -86°C.
• The two circuits work together for fast temperature recovery.
• Should a service event occur, temperatures will hold at -70°C.
• With two independent systems, each sustaining ultra-low temperatures, your samples remain safe.
• Optional CO₂ backup provides an extra layer of protection.

Superior Temperature Uniformity

• Redundant auto-cascade refrigeration systems unique to TwinGuard Series achieve superior temperature stability during initial startup and maintain uniformity.

Maximized Storage Capacity for Efficient Use of Lab Floor Space

• The cabinet and door insulation are constructed using patented VIP Plus thin-profile vacuum insulation to maximize storage capacity and optimize the use of floor space.
• This thin-wall composite insulation
• The highly efficient insulation also improves temperature stability following frequent door opening and extends warm-up times during power outages.

Intelligent Color LCD Display

• Easy to read close-up or from a distance
• High contrast color LCD allows for easy touchscreen use.
• The display panel includes comprehensive audible and visual warnings, unit diagnostics, running temperature logs, and predictive analytics.
• A USB port makes transferring this logged data to a PC convenient.
• All performance attributes are displayed, and an internal time/temperature log is expressed in graphic form.

Microprocessor Controller and Alarms

• TwinGuard ultra-low temperature freezers are managed by a microprocessor-based controller that combines security, monitoring, predictive performance,, and data logging functions into a single display with password-protected menu screens.

Energy-Efficient

• They are designed and constructed for peak performance and reliability while maintaining efficient operating costs.
• An ECO mode provides additional energy savings.

EZlatch Ergonomic Design for Quick Access and Positive Door Closure

• The patent-pending EZlatch is engineered to tolerate frequent door openings.
• One-handed access and control frost associated with extreme temperature differentials.
