Laboratory Refrigerator Power Failure Alerts

A laboratory refrigerator may continue to look normal from the outside even when an electrical problem has interrupted its operation. If a power failure happens outside working hours, staff may not notice it immediately.

For facilities storing materials that require refrigerated conditions, knowing that an electrical fault has occurred can be important for taking the appropriate next step.

The Laboratory Refrigerator (Single Door) 108L from Caresource Global includes a dedicated power fault alarm, along with temperature, thermostat, and door monitoring alarms.

Why Power Failure Alerts Matter in a Laboratory

Refrigerated storage depends on continuous operation of the cooling system. When electricity is interrupted, the refrigeration system cannot function normally.

Consider a simple situation:

A laboratory closes at 6 PM. A power interruption occurs at midnight. Staff return the next morning and discover that the refrigerator has been without power.

Without an alert, the interruption may only be discovered after several hours.

A power fault alarm provides an indication that an electrical issue has occurred, allowing responsible personnel to investigate the situation according to their laboratory’s procedures.

What Does a Power Fault Alarm Do?

A power fault alarm is designed to alert the user when the refrigerator detects a power-related fault.

It is particularly useful in situations where the unit is operating without continuous supervision, such as:

Overnight operation
Weekends
Storage rooms
Research facilities
Restricted-access laboratories

The alarm does not prevent a power outage. Its purpose is to make the fault known so that appropriate action can be taken.

A Practical Example

Imagine a research laboratory using a refrigerator for materials requiring controlled refrigerated storage.

During normal working hours, staff can easily notice if the refrigerator stops operating. But an outage at night creates a different situation.

With a power fault alert, the event can be identified rather than remaining unnoticed until the next inspection.

The response may then involve checking:

Whether the building’s electrical supply has been restored
Whether the refrigerator is operating correctly
The recorded or observed internal temperature
How long the interruption lasted
Whether the stored materials require additional action

The appropriate response will depend on the laboratory’s own storage procedures and the materials involved.

Multiple Alarms for Different Situations

The 108L model does not rely on one alarm for every condition. Its alarm system covers several operating situations:

High temperature alarm
Alerts when the internal temperature becomes too high.

Low temperature alarm
Indicates when the temperature falls below the configured operating condition.

Power fault alarm
Provides an alert related to a power fault.

Thermostat fault alarm
Indicates a potential thermostat-related problem.

Door ajar alarm
Alerts when the refrigerator door has not been properly closed.

This separation makes it easier to identify the type of problem requiring attention.

Controlled Storage Between 2°C and 8°C

The refrigerator operates within a 2°C to 8°C temperature range and has a stated temperature accuracy of 0.1°C.

A microprocessor control system manages the unit, while the digital tube display provides a direct way to view operating information.

This combination is designed for facilities where maintaining a defined refrigerated environment is part of routine storage requirements.

Air-Cooled Refrigeration and Automatic Defrost

The unit uses an air-cooled refrigeration system with R600a refrigerant, a CFC-free refrigerant.

Automatic defrost is also included, reducing the need for routine manual defrosting.

The refrigeration system uses a copper tube and aluminum fin condenser/evaporator arrangement, with a Bundy tube.

Compact 108L Storage Capacity

With a 108L capacity, the unit is suited to facilities looking for a relatively compact refrigerated storage solution.

Its dimensions are:

495 × 548 × 934 mm (W × D × H)

The refrigerator comes with three shelves, allowing the available space to be organized according to the user’s storage requirements.

The construction uses spraying steel plate for both internal and external materials, with polyurethane cyclopentane insulation.

Standard and Optional Accessories

The standard configuration includes:

LED lamp
USB port

Depending on the required setup, optional accessories include:

Temperature recorder
Printer
Additional shelf
RS485 port
Temperature analysis port

These options can be selected when additional recording, communication, or monitoring capabilities are required.
