So-Low's Superior Construction

Ultra low freezers have a 16-ga. exterior (cold rolled steel). Interiors are 14 gauge vs. competitions 16 gauge. Ultra low freezer interiors are galvanized, non-corrosive steel. Galvanized steel conducts temperature more efficiently than stainless steel. This creates less stress on compressors making them run cooler and longer.

So-Low's Digital Control

So-Low is the only ultra low temperature manufacturer to utilize a dual display digital temperature control. A red LED display indicates the actual interior chamber temperature while a green LED display located directly below the red display shows the actual setpoint temperature. This will give assurance that the freezer is operating at the correct temperature range whereas other manufacturer's temperature controls show only the actual temperature and not both the setpoint and actual temperature.

FAQ

What side does the door open from?

The door opens from the left side (the hinge is on the right), as in the picture below. If you need it the other way around, please inquire about having the door customized.

Are the So-Low Ultra Low Upright Freezers UL listed?

No, but they are ETL listed, which is a legally equivalent marking from a different organization. Just like UL listing, ETL listing serves as proof of product compliance to North American safety standards in both the US and Canada.

 

What is the weight capacity of each shelf?

75 pounds.

 

Do the So-Low Ultra Low Upright Freezers have a lock?

The latch of the freezer is lockable with a padlock. They do not have a built-in keyed lock.

 

What insulation is used and how much is there?

The insulation is a 5 inch thick polyurethane foam.

 

What is the life expectancy of one of the So-Low Ultra Low Upright Freezers?

If a freezer kicks the bucket, it's probably because the compressor went. So this is really a matter of how long the life of the compressor is. The manufacturer of these compressors puts them through a stress test which simulates, in an accelerated fashion by means of having additional load on it, 8 years of normal wear. According to this test, a So-Low ULT should last at least 8 years.

However, there are situations where you can decrease the life of your compressor. Most of these involve additional stress on the compressor, for instance:

  • Opening and closing the door frequently
  • Having the unit in a hot and / or dirty environment
  • Not cleaning the area around the compressor and allowing dust to build up on the components
  • Not replacing worn door gaskets, if necessary

So under heavy load, in a harsh environment or under conditions of poor maintenance, your ULT might not last as long. This would be true for any freezer.
