Gelu is on every product pageJust ask a question, anytime
What temperature range does this benchtop ULT reach?

The temperature setpoint range is 40°C to -86°C. Pull down time to nominal operating temperature is less than 210 minutes to -86°C in an empty chamber.

Temp Controller tab
What are the exterior dimensions and weight?

Exterior dimensions are 10.25" wide, 11" deep, and 18.5" high. Product weight is 21 lbs and shipping weight is 40 lbs.

Details tab
How much clearance does the unit need for ventilation?

The freezer requires a minimum 2" of clearance at the back and sides of the unit for proper ventilation.

Temp Controller tab
What refrigerant and compressor does this freezer use?

It uses a Stirling engine compressor with helium refrigerant. The condenser is an integral heatsink and the evaporator is an integral cold plate. Defrost is manual.

Refrigeration System tab
What are the electrical requirements and plug types?

The AC configuration requires 110-127V, 15A on a NEMA 5-15 receptacle with a NEMA 1-15P plug and draws 1 Amp. The DC configuration uses a 12V automotive socket with a 15A fuse and draws 10 Amps.

Details tab
What alarms are included and is there any battery backup?

The unit provides audible and visual alarms when the temperature is above the set point by 10°C for 5 minutes. An adapter is included for 12V socket power as a battery backup option; an external alarm connection is not applicable.
