Here are common questions and answers about this product

Gelu is on every product pageJust ask a question, anytime
What temperature range can I set on this refrigerator?

The adjustable temperature range is 2° C to 15° C, controlled by a microprocessor temperature controller with variable frequency compressor control, switchable between C° and F° with a resolution of 0.1° C/0.2° F.

Temp Controller tab
What are the exterior dimensions and weight?

The unit measures 54″ wide, 34.75″ deep, and 81.75″ high. Product weight is 448 lbs and shipping weight is 540 lbs.

Details tab
How much clearance does it need for ventilation?

The refrigerator requires a minimum 2″ of clearance at the back and sides for proper ventilation.

Temp Controller tab
What alarms does it have?

It includes audible and visual high/low temperature alarms, remote alarm contacts, a sensor error alarm, a power failure alarm, and a door ajar alarm. A battery backup supports the controller temperature display and alarms only, with no cooling active.

Temp Controller tab
What are the electrical requirements?

It is rated at 3 Amps and uses a NEMA 5-15 plug. The facility must provide 110–120V AC with a 15A breaker and a NEMA 5-15 receptacle.

Details tab
What refrigerant and defrost type does it use?

The system uses EPA SNAP compliant R600a Isobutane, a hydrocarbon natural refrigerant, with a hermetic variable speed compressor and cycle defrost.

Refrigeration System tab
What is a Variable Speed Compressor (VSC)?

A variable speed compressor (VSC) self-adjusts to cooling demand instead of running at one fixed speed, giving greater efficiency and more cost savings than a traditional fixed-speed model. On this unit it works alongside the microprocessor temperature controller, which provides the precise temperature control.
