Freezer Features and Benefits

Security and Data Management

i.Series Upright ULT Freezers feature the i.C3 User Interface that provides constant temperature monitoring and control, security and multi-information logs

Heat Barrier System Reduces Frost

Heat Barrier System features a fortified outer door and a reinforced insulated inner door that prevents frost build-up by minimizing temperature fluctuations

Ice-Resistant Sealing Surface

An ice-resistant sealing surface features an energy-efficient hot gas loop for a frost-free door frame and composite panels reduce heat transfer

Frost Reduction

Polygonal gaskets on the outer door compresses against the frame and forms a tight seal that prevents migration of moisture and reduces frost build-up

Dual Blade Gaskets Eliminate Frost

Dual-blade gaskets between the swing-out inner doors (with a positive latch) stop warm air from entering the storage chamber for ensured temperature uniformity

Optimum Oil Management

Models feature an oil separator that protects the compressor and an optimized mixed refrigerant that ensures proper flow rate at extremely low temperatures

Ergonomic Door Handle with Key Lock

An easy-to-open door handle made with heavy-duty, cast aluminum and hardened steel includes a key lock and a padlock hasp for security

Revco ExF ULT Freezer Eye Level Microprocessor Controller

Eye level microprocessor controller provides convenient operation of alarms, modes and temperature display; shows vibrant display of ULT freezer temperature.

Internal Doors and Security Features

Padlock-compatible doors, ergonomic door handle, eye-level touchscreen, alarm settings and an optional access card entry

Capacitive Touch Interface

Touchscreen display can be used with latex gloves and features a set-up wizard, event log, temperature mapping and a USB port

Five Interior Compartment Doors

Revco Series ULT Freezers have 5 internal compartments that protect samples by reducing cold air loss and improving temperature recovery time after opening the freezer.

Air Filter Access

Maintenance is easy with a Revco ExF Ultra-Low Temperature Freezer: simply open the access panel and slide out the air filter for replacement.

Revco Convenient Access Ports

Convenient Access Ports are located on the right and left side of the Revco ExF Ultra-Low temperature freezers by Thermo Scientific.

More Information

TSX V-Drive Technology

Variable speed compressors and adaptive controls adjust to both internal and external conditions. The control system detects multiple door openings (such as when adding samples to the freezer) and increases the drive speed to expedite recovery times. Once conditions stabilize, the compressors will slow down to the minimum idle speed to maintain the temperature setting, preventing wasted electricity. Two internal doors protect samples from temperature changes and reduce ice buildup, providing further energy savings.

A conventional ULT freezer has a single-speed compressor, requiring on/off cycles that increase wear-and-tear on the compressor, shortening its usable life span. The single-speed design slows door-opening recovery and wastes energy by inefficiently switching between maximum speed and zero.

Sustainability Features
  • Dual hermetic compressors use natural, hydrocarbon-based refrigerants R170 Ethane and R290 Propane
  • Water-blown foam insulation cuts down refrigerant out-gassing as foam ages
  • Award-winning, zero-waste-to-landfill production facility recycles 93% of waste and converts 7% of waste into energy
Natural, Hydrocarbon Refrigerants

The TSX Series employs hydrocarbon refrigerants due to their excellent thermodynamic properties, low Global Warming Potential (GWP) and zero ozone depletion. Hydrocarbon refrigerants are also better for the compressors, as they eliminate the lack of oil return associated with conventional refrigerants. The TSX-Series is UL and CE certified and adheres to the strictest safety standards.
