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. Maximum temperature variation (cabinet air) is +/- 2.0° C, and stability on the simulator ballast is +/- 0.5° C.

Refrigeration System tab
What are the exterior dimensions and weight?

Exterior width is 39.625″, depth is 32.5″, and height is 81.75″. Product weight is 355 lbs and shipping weight is 419 lbs.

Details tab
How much clearance does it need for installation?

The refrigerator requires a minimum 2” of clearance around the back and sides for proper ventilation, and more if next to heat rejecting equipment. Improper installation will void the warranty and will lead to temperature maintenance issues, overheating and possible failure.

Temp Controller tab
What alarms are included?

The unit has audible and visual high/low temperature alarms, remote alarm contacts, sensor error alarm, power failure alarm, door ajar alarm, and alarm mute. Battery backup supports the controller temperature display and alarms only, with no cooling active.

Temp Controller tab
What are the electrical requirements?

Rated amperage is 3 Amps with a NEMA 5-15P plug. The facility must provide 110 – 120V AC, a 15A breaker, and a NEMA 5-15 receptacle.

Details tab
What refrigerant and defrost type does it use, and what is the warranty?

It uses EPA SNAP compliant R600a Isobutane (hydrocarbon natural refrigerant) with Cycle Defrost. The warranty is two (2) years parts and labor, with a seven (7) year compressor warranty.

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.
