Firm promises to ‘disrupt the decades-old compressor paradigm’ with solid state freezer

Phononics claims new levels of temperature stability with its Evolve solid state medical freezer

US solid state cooling specialist Phononic has unveiled a cold storage unit which claims unrivalled temperature stability for medical applications. The Evolve compact freezer – a compressor-free, pharmacy-grade 1.8 cubic foot (50 litre) freezer features proprietary the company’s proprietary SilverCore solid-state technology.

Phononic claims: “By efficiently moving particles of heat known as phonons via non-toxic coolant, SilverCore technology is revolutionising the ability to create cold temperatures.”

Tony Atti, founder and CEO of the firm said: “Our solid-state technology achieves freezer performance thought impossible from a solid-state solution, represents a refrigeration milestone and meets the demanding requirements of healthcare professionals. Our commitment to disrupting the decades-old compressor paradigm will help further life-changing research and stop putting vital inventory at risk.”

The Evolve will enable a range of medical products – from tissue samples to vaccines to blood to medicines – to be stored at ‘precise, stable and uniform temperatures’ between  -15 deg C and - 25 deg C in normal ambient working environments, while accommodating temperatures up to 32 deg C, Phononics noted.

The Evolve also features  Wi-fi-based monitoring, enabling live reports to be generated, sending alerts in case of out-of-temperature situations. The firm noted that this function could save significant cost in preventing lost products or avoiding compromised research results.

Mike Demasi, vice president and general manager of Phononic’s Cold Products business added: “Evolve consumes significantly lower energy than a compressor-based system and because it’s so energy efficient, it can run on a battery backup power supply for several hours, adding even more peace of mind for our customers in hurricane-prone regions of the US or countries with inconsistent supplies of power.”

Production of the Evolve freezer is planned for late 2015. The Evolve follows the launch of a 50 litre refrigerator with SilverCore technology last month. In addition, an undercounter refrigerator is scheduled for launch in 2016.

The firm believes that use of the semiconductor-based technology will enable the rethinking of refrigerator design, since there is no space requirement for compressors and no refrigerant gases in the system.
