Glacier Polar Edition Model NU-9728 Vacuum Insulated Panel Technology  

Vacuum Insulated Panel Technology

A vacuum insulated panel is a high efficiency composite material that through a vacuum is placed into the exterior frame of the freezer eliminating air build up within the insulation. This technology provides more useable space, minimizes moisutre build-up, improves temperature uniformity, and more.




Glacier Polar Edition Model NU-9728 Control Panel

Simplified Eye-Level Controls

[1] Temperature - Digital display defaults to actual chamber temperature. Display mode changes when setpoint, alarm parameters, programming and diagnostic functions are performed.
[2] Status Light - Status alert function uses predictive intelligence to determine if freezer is operating within specifications under existing environmental conditions.
[3] Battery Light - Ni-MH battery powers control memory and alarm functions during power failure.
[4] Alarm Light - Alarm indicator lamp glows when freezer is in alarm condition; alarm ringback is factory set for 30 minutes, adjustable in 10 minute increments from 10 to 60 minutes.
[5] Filter Light - Filter indicator lamp glows when electrostatic filter requires removal for cleaning.
[6] Door Light - Door alarm indicator has 2 minute delay until audible alarm activates; delay time is adjustable.
[7] Right Arrow - Setpoint entry advances digital display to  next position.
[8] Up Arrow - Setpoint entry advances digital to next value  from 0 to 9.
[9] Set Button - Press to set temperature; set button is also used for other diagnostic functions.
[10] Alarm Test Button - Alarm test verifies readiness of alarm function and Ni-MH battery charge.
[11] Buzzer Button - Buzzer silence temporarily mutes alarm.
[12] Compressor start-up delay sequence delays re-start after  building power failure; allows facility power to reach equilibrium to permit smooth compressor start-up.
