Refrigerants compliant with the new F-Gas regulations

As global warming and ecology in general are at the heart of our concerns, the refrigerants used in all Froilabo freezers comply with the new F-Gas regulations (EU No. 517/2014).

Cryo-accumulator Option

Achieve optimised performance with Froilabo’s cryo-accumulator option. The cryo-accumulator ensures a delayed temperature rise in the event of power failure giving the user up to 18 hours to safeguard samples. Room temperature, volume of content within freezers and frequency of door openings can all affect temperature changes.
