Key features
- Two SECOP compressors form the cascade cooling system.
- The chamber uses direct cooling and manual defrost.
- An optional LN₂ backup and optional racks must be specified separately.

Installation and use
Confirm the electrical version before installation. Rated power is an electrical rating, not daily energy consumption. Storage temperatures and acceptance criteria must follow the material instructions and the facility’s approved procedure. The temperature display does not replace an independent monitoring and alarm response plan.
Frequently asked questions
How should storage capacity be selected?
Consider container dimensions, quantity, rack layout and space needed for air circulation or sample retrieval. Nominal chamber volume is not the same as usable loaded volume.
Does a 0.1 °C display imply 0.1 °C temperature uniformity?
No. Display resolution, stability over time and spatial temperature uniformity describe different properties. Validate the usable storage area through temperature mapping under the agreed protocol.
What should be confirmed before delivery?
Confirm the exact model revision, electrical supply, door arrangement, access route, ventilation clearance, shelves or racks, monitoring and backup provision. List optional accessories separately in the order specification.
Does the alarm battery run the cooling system?
An alarm backup battery in a stationary freezer does not power its compressors. Continued cooling requires suitable backup power or a compatible backup cooling system. Portable freezer run time depends on the actual battery and operating conditions.
