Main features

Single compressor technology
Single compressor technology with a simple structure that ensures easy maintenance, lower heat dissipation, low energy consumption, and noise reduction.

Filterless construction
Filterless construction prevents dust from blocking the airflow and reduces the unit’s ability to dissipate heat effectively, which minimizes maintenance procedures.

Direct cooling
Direct cooling for optimized temperature stability and uniformity, even with multiple door openings.

Heated door frame
A heated door frame prevents ice from building up around the gasket securing a stable and uniform temperature inside the freezer.

Heated vacuum release valve
The heated vacuum release valve ensures that the doors can always open, making the unit perfect for an active work environment.

100 % HCFC & CFC free
