HERAfreeze™ HFU T Series -86°C Upright Ultra-Low Temperature Freezers


Protect a large amount of samples in a single area with Thermo Scientific™ HERAfreeze™ HFU T Series -86°C Upright Ultra-Low Temperature Freezers. These new freezers achieve outstanding thermal performance, safety and security through state-of-the-art engineering. They are environmentally-friendly, with CFC/HCFC free refrigerants. Available in five sizes, they store 300 to 700 2″ boxes per freezer.†
Customize your freezer with several optional features including LN 2 and CO2 back-up system, chart recorder, stainless steel inventory racking solutions and a hands-free locking option.


New Features
Cabinet + Vacuum Insulation Panel Technology increases the internal capacity of 2″ vials up to 4.2 percent‡—gain up to 76% more capacity in the same footprint‡— with 1mL CryoBank tubes.
High-efficiency compressors for outstanding performance and reliability
Store up to 278 lb. of samples (depending on freezer model) on reinforced, stainless steel shelving.
4×7 heated gasket provides four touchpoints of security and seven zones of protection, maximizing cabinet temperature and eliminating frost build-up.
Five polystyrene insulated inner doors help maintain cabinet temperature during openings and feature embedded rare earth magnets, eliminating exposed latches.

Innovative Technology
Feature a touch-screen control panel that allows 24/7 monitoring of the freezer's health provides access to a detailed event log—built-in USB port enables easy downloading of temperature and event log reports to a portable drive, or freezer settings from one freezer to another.
Store up to 15 years worth of temperature and event data on our on-board computer.
Power management system protects against a wide range of voltage variation and is easily accessible through the touch-screen display.

Temperature Control
Features an outstanding BTU (British thermal unit) reserve, leading to fast door recovery times so that sample integrity isn't compromised.†
High-performance mode provides the tightest temperature uniformity and peak variation‡—for most applications, energy-savings mode offers excellent temperature control, plus up to 15% savings on energy usage.
Brazed plate heat exchanger for more efficient heat transfer—induction brazed joints to reduce leak potential and improve reliability

Key Benefits
Freezers maximize sample storage capacity while minimizing the freezer's physical space inside the lab.
Freezers allow up to 15% savings in energy usage with the energy-savings mode‡ or choose the high-performance mode for applications requiring ultra-tight temperature uniformity—all through an easy-to-use, touch-screen interface.
Remote alarm contacts come with 4-20 milliamp output compatible with external alarm and monitoring systems.
Two rear access, 1″ (25mm) ports allow for the use of inexpedient probes or instrumentation.
Easy-to-remove, washable filter provides protection against dust on the condenser, which can cause reduced refrigeration performance and increased risk to samples.
