Features

Next generation “Twin Guard” Dual Cooling system with reduced power consumption.

The next generation Twin Guard Eco Ultra Low Temperature freezers use natural refrigerants and inverter controlled compressors, reducing energy usage, with enhanced access control via an electronic lock with facial recognition (optional) to provide the highest level of protecting for your valuable samples.

Ultimate Sample Protection

The Dual Cooling System offers high levels of protection through the use of two independent refrigeration systems. If one system unexpectedly fails the other can maintain the freezer in the -75°C range.

Performance and Reliability

Naturally occurring hydrocarbon (HC) refrigerants have minimal effect on the environment. Combined with inverter technology, these refrigerants also provide more efficiency without compromising cooling performance, ambient tolerance, and recovery speeds following door openings.

Security control and Monitoring

An eye level, door mounted, 10.1 inches high resolution LCD touchscreen allows full user control. A USB port makes transferring logged data to a PC convenient. All performance attributes are displayed and an internal temperature log can be expressed in graphic form over time.

Valuable Sample Storage

Securely store valuable and irreplaceable samples with the utmost confidence that they won’t be lost in the case of compressor failure.

Natural Refrigerants

Natural refrigerants, compressors and integrated electronics combined to lower operating costs resulting in less energy consumption and less heat output. Freezer operation is managed by effectively balancing temperature performance and energy management.

 

Electronic Door Lock

Know who entered the freezer and when. Track how long the door was open.
3 Ways to Lock
• Pin code
• Unique individual key
• Facial recognition (optional)

Dual Cooling System.

The Dual Cooling System offers ultimate sample protection. The two independent refrigeration systems provide a reliable and exceptionally stable -86°C ultra low temperature environment. If one system unexpectedly fails, the other can maintain the freezer in the -75°C range until service can be arranged.

Filterless Design

The filterless construction of the freezers reduces routine maintenance time by eliminating the need for regular cleaning of filters.

Innovative Cabinet Design

The enhanced cabinet design with chamfered edges reduces footprint for use in multi freezer laboratories.
