Frequently Asked Questions

How does the cascade system work in the B 35-85?

The unit uses a two-stage cascade refrigeration system to reliably achieve extremely low temperatures of down to -85°C. Two separate refrigeration circuits work together efficiently, with the first circuit cooling the second. This ensures stable cooling performance and protects the mechanical components for a long service life.

Can the freezer be placed in a space-saving manner in tight laboratories?

Yes, the B 35-85 is designed to be particularly space-saving due to its compact external dimensions and stackability of up to four units. Since the cooling air vents are located on the sides, the unit can be placed directly against the wall with its back. With a noise level of only 43 dB(A), it is also very quiet in operation.

What safety features does the unit offer in the event of a power outage?

The freezer features an integrated battery that maintains the visual and audible alarm system for up to 72 hours in the event of a power outage. A potential-free contact also enables connection to an external alarm system for remote monitoring. A temperature recorder can additionally be connected via the 10 mV/K output for seamless documentation.
