Purpose-Built Cold Chain Storage
PHCbi brand ULT freezers are engineered from the inside out to create, maintain and restore precise temperatures necessary for vaccine storage. Our purpose-built ultra-low temperature freezers are designed for temperature uniformity and stability that is not commonly found with household or commercial cabinets. Ultra-low freezers provide reliable temperatures as low as -80°C and are suitable for the storage of certain new and emerging vaccines. PHCbi brand vaccine cold chain storage solutions satisfy current and evolving storage protocols essential for continued vaccine efficacy.
Ultimate Sample Protection with Redundant Refrigeration
The patented TwinGuard Dual Cool compressor system from PHC uses two cooling systems to double the level of sample protection. The two circuits work together for fast temperature recovery, while the secondary system keeps the temperature at -70°C if a service event occurs.
Superior Temperature Uniformity
Redundant auto-cascade refrigeration systems unique to TwinGuard Series achieve superior temperature stability during initial startup and maintain uniformity following routine door openings and throughout the steady state, minimizing the loss of cold air even when the freezer lid is open.
Maximized Storage Capacity for Efficient Use of Lab Floor Space
Patented VIP Plus (vacuum insulation panels) of the TwinGuard Series ultra-low temperature freezers, maximizes storage capacity and optimizes use of floor space. This thin-wall composite insulation includes narrow-profile vacuum panel layers supported by foamed-in-place 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
An eye level, door mounted color LCD touchscreen allows full user control while the USB port makes transferring logged data to a PC convenient. This full function display panel includes audible and visual warnings, unit diagnostics, temperature and door opening history. All performance attributes are displayed and an internal temperature log is expressed in graphic form over time.
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
TwinGuard Series freezers are designed and constructed for peak performance and reliability while maintaining efficient operating costs. An ECO mode provides additional energy savings.
