Thermo Scientific TSU -86C Ultra Low Upright Freezer, 24.1 cu ft
Part Number: TSU500A
Touch-Screen Control Panel
The highlight of our TSU freezers is an innovative, touch-screen control panel. Here you can control all freezer settings and user authority levels, as well as monitor the freezer's health 24/7 and access a detailed event log. Need a record? Simply download a report of the event log to a portable drive via a built-in USB port.
Two Modes: High Performance, Energy Savings
For customers who require the strictest tolerances, our high-performance mode provides the tightest temperature uniformity and peak variation. For most applications, our energy savings mode offers excellent temperature control, plus up to 15% savings on energy usage by controlling the temperature and time of the cycles.
Health Monitoring System
You can check your freezer's "health" at any time by simply touching the heart icon on the main screen. Here, you will see the freezer's temperature, alarms, and freezer system status.
If the heart icon is blue, your freezer is in good health and is protecting your samples.
In the event the heart's color changes to yellow, something needs to be addressed. The yellow heart provides indications of system status, battery alerts, preventative maintenance reminders, ambient alerts and unacknowledged alarms.
A red heart indicates there is a problem. Should this occur, you will be notified with visual and audible alarms. Conditions causing a red heart include warm and cold alarms, door open alarms and power failure.
See What's Happening Inside!
If at any time you want to see what's going on inside the freezer, you don't need to open the door (despite our excellent recovery times). The following are just a finger stroke away:
Alarm Status: including active alarms and past events
Door Opening Status: How many door openings and length of time the door was open.
Temperature Status: What is the actual temperature? When was it at its warmest and coldest? Need more detail? - press the thermometer to get the temperature status at 8 points in the freezer and refrigeration system.
Environmental Conditions: See a summary of the ambient temperature and the incoming electrical voltage.
Backup System Status: CO2 or LN2 is actively injecting into the freezer. "Green" means good. "Yellow" indicates caution. "Red" signifies "fill up now."
Who is using this freezer?
Our freezers have multiple security levels to fit your lab requirements. No access control required - use our fully accessible mode and this freezer operates like any other.
Need to restrict who can change setpoints? Use our secure mode where you can designate different types of users. General users can operate all aspects of the freezer but do not have access to change settings. Administrators can change freezer and alarm setpoints, as well as add or delete users.
What happened, when, where?
Because each one of your samples is precious, we've developed an intuitive event log as part of our touch-screen control panel. And, you can easily export your event log data via the USB port in the front of the unit to Microsoft™ Excel®. Simply insert your drive into the USB outlet and touch the download icon.
Do you have multiple freezers?
No problem. Simply load the data from one freezer to the next via the USB drive. This simple action takes the freezer setpoints and user database from one freezer to another.
The industry's fastest Door Opening Recovery! If you open all FOUR inner doors for one full minute (not a likely situation), the freezer will recover to -86°C in 28 minutes.
Reinforced, stainless steel shelves hold 125 pounds of weight
Freezer contains four independently sealed compartments allowing access to samples without subjecting entire freezer to ambient temperatures. The five polystryene insulated inner doors feature embedded rare earth magnets, eliminating the need for exposed latches or magnets.
4x7 heated uuter door gasket provide four touchpoints of security and seven zones of protection, maximizing cabinet temperature and minimizing frost build-up
