RIGID: Your Premier Ultra-low Temp Vaccine Freezer
RIGID ultra-low temperature portable vaccine freezer-RG01L86 adopts international advanced Stirling technology. With a small footprint, it can be used in hospitals, laboratories, research institutes, and other medical facilities. The temperature of this vaccine freezer can reach as low as -86℃, which is specifically designed for vaccine storage and transportation. Its intelligent temperature controller is able to maintain a precise temperature of ±0.1°C to protect vaccines from any harmful effects of changing temperatures.
This Stirling vaccine freezer has a built-in large-capacity lithium battery, which can work for more than 1 hour without an external power supply. Stirling technology is a breakthrough in small and deep freezing. It can be used in abundant applications, also a better alternative to a refrigerated compressor. RIGID breakthrough cooling technology makes the Stirling ultra-low temperature (ULT) freezer uniquely efficient, lightweight and flexible enough to meet today’s unprecedented COVID-19 vaccine cold chain deployment challenges.
