Part of the Standard Performance (STP) family, Thermo Scientific™ TDE ultra-low temperature freezer packages include one ultralow temperature freezer, two shelves of sliding drawer racks and boxes, and a factory-installed CO₂ back-up system.

Performance
• Powered by H-drive's hydrocarbon technology, these systems save up to 25% in energy usage and heat rejection over conventional refrigerant ultra-low freezers
• Designed for daily usage, recovers cabinet temperature 20% faster after opening the door
• A quiet sound output below 53 dBA, enables the freezer to come out of the hallway and into the lab
• Meets +/-10°C validation protocols at -80°C with strong peak variation and steady-state temperature variation
• Natural hydrocarbon refrigerants reduce system operating stresses promoting outstanding reliability and worry-free sample protection

User Friendly
