SuperFreezer Ultra-low temperature Unit

Ultra-low temperature for critical cargo

Designed for seagoing transport refrigeration applications, SuperFreezers can also be used on land by plugging in the 360-500 Volt 50 or 60 Hz power supply. Its exceptional high performance offers protection for valuable pharmaceuticals or blood plasma, and preserves first-day product freshness of seafood (Grade A sashimi, tuna, salmon). As low as -65°C in 40ft special insulated containers, and -70°C in 10ft and 20ft special insulated containers.
